Having sustained an electric shock, ALWAYS consult a doctor.


Introducing the mc²36


System Components

The mc236 is an all-in-one digital mixing console with integrated power supplies, DSP processing and I/O

connections. The console has a similar architecture, operating system and application software to other mc2

products. As a result, it benefits from a powerful feature-set and can be networked to the other mc2 systems. Theconsole is available in three standard sizes: 16, 24 or 40-fader:

16-fader 24-fader 40-fader

Unlike other mc2 consoles, the mc236 is a self-contained unit. The integrated DSP micro-core provides a 512 x512 digital routing matrix and two physical DSP boards. Local I/O, within the console frame, provides 32 mic/linein, 32 line out, 8 AES in, 8 AES out, 1 stereo headphone out, 8 GPIO, 1 MADI and 3 RAVENNA ports. To expand

the I/O capabilities, you may connect up to three Compact I/O stageboxes, or network to other mc2 systems, viathe console's RAVENNA ports. Any source can be routed to any input channel, and any output bus or channelsend routed to any destination. In addition, you may route sources directly to destinations, for example to feed amic/line in to an AES out.

Signal Flow & Processing

The DSP resources provide a mixture of input channels (INP), monitor return channels (MON), groups (GRP),main outputs (SUM) and auxiliary sends (AUX). The exact numbers are determined by your choice of productiontemplate. Each channel comes with either full or reduced signal processing (known as tiny channels). Thisenables EQ, Dynamics, Delay, etc. to be applied to both inputs and outputs. The production template alsodetermines the channel type (Broadcast or Recording), and whether DSP redundancy is active.

Broadcast Channels – more channels with simplified signal processing (no track bus send; noindependent filter section; simpler dynamics):

Recording Channels – less channels with more signal processing and increased flexibility:

Channels can be configured for mono, stereo or surround operation. The following tools provide easy managementof surround sources and outputs: Surround VCAs (master control from a single fader strip); REVEAL (reveal thesurround slaves); Hyper Pan (reposition a surround source); AMBIT (5.1 upmix and spatialise processing);Downmix Matrix (convert 5.1 back to stereo).



Banks & Layers

Any physical fader strip can control any input, monitor return, group, sum, aux, VCA or Surround VCA. Thisallows you to lay out your source channels, audio masters and control masters where you want them. Theconsole supports six control surface banks (1 to 6), each with two layers - Layer 1 and Layer 2. Think of eachbank as a separate console, with fast global switching from one bank to another. Within each bank, layers can beswitched globally or individually. This makes layers ideal for related channels. For example, you could assign apresenter's input channel to Layer 1 with their mix minus aux master on Layer 2.

Console Reset

One of the major benefits of the mc236 is the ability to store and recall your mix:

Productions form the top level for user data storage and store all the settings required for a production ortype of job. Within each production, folders are created to store snapshots.

Snapshots store different mixes for recall before or during the show. For example, to recall a different mixfor each band in a live entertainment show, or to recall scene changes during a live theatre production. Tomanage recall, snapshot isolate and filtering may be applied to protect channels or elements of the desk.

A Sequence is a list of snapshots which can be loaded in sequence during a live show. The transitionbetween snapshots in a sequence can be cross faded if required. In addition, offsets can be applied todeal with last minute changes such as a change of artist.

Presets are stored independently of productions and snapshots. They can save and load settings forindividual processing modules (EQ, Gate, Compressor, Panning, etc.) or for a complete channel. Forexample, you may wish to save your favourite vocal EQ, or the complete settings for an announcerchannel.

All user data is stored on the system's internal flashcard and may be imported and exported to a USB memory

stick or mxGUI computer. Note that, unlike other mc2 systems, the mc236 does not support timecode-basedautomation.

mxGUI (Matrix GUI)

mxGUI is a Lawo software programme which runs on an external computer to provide offline setup or remote

operation of any mc2 system. You can work offline to create productions, snapshots, sequences and presetswhich can then be transferred to the console at a later date; thus saving valuable setup time before a show. Whenrunning online, mxGUI can provide an additional screen display or remote operation for a second engineer. Formore information on mxGUI, please refer to the Operators Reference Manual.

Configuration

The mc236 is delivered in a fully-configured state from the factory. The console comes with a selection ofproduction templates which configure the DSP resources, make default routing assignments (sources andoutputs) and assign the console's fader strips. By loading a template and connecting your external signals youwill be ready to mix very quickly.

The console surface includes a number of user buttons which you may re-programme from the Central GUI'sCustom Functions display. The default functions are covered in this manual. For more information on user buttonfunctions and their programming, please refer to the Operators Reference Manual.

Compact I/O (optional Stagebox)

The Compact I/O is an external stagebox (5RU) providing 32mic/line in, 32 line out, 8 AES in, 8 AES out, 8 GPIO and 1MADI port. Up to three units may be connected via theconsole's RAVENNA ports.

If a new Compact I/O stagebox is installed, thenthe system configuration must be edited usingAdminHD. Please refer to the Compact I/Ochapter for details.

Central Control Section

Central GUI

Centre Section

Rear Connector Panel


Quick Reference

The Control Surface

1 Channel Display - metering and touch-screen operation of channel assignments.

2 Fader Strips - 24* dedicated fader strips (* dependent on the frame size).

3 Central Control Section - master channel control for the selected fader (EQ, DYNAMICS, etc).

4 Central GUI - touch-screen operation of the console's setup displays.

5 Console Keyboard - space for the console keyboard and its USB port.

6 Centre Section - master controls including SCREEN CONTROL (Central GUI) navigation.

7 Headphone & USB Ports - 1 x stereo headphone out and 2 x USB ports.

The 16-fader console is fitted with a single touch-screen (4). In addition, the console keyboard (5) isfloating and should be connected to one of the front buffer USB ports (7).

On 40-fader consoles, the left-hand channel bay includes some additional fader strip controls: A/Binput and local BANK/LAYER switching.


Quick Reference

Channel Display

The Channel Display is a high resolution touch-screen providing visual feedback and touch-basedoperation of channel metering and assignments.

Up to three metering rows may be enabled. The lower row always meters the active bank/layer, whilethe upper rows can be assigned to a "hidden" bank/layer of channels (defined by the "Metering Row"options in the System Settings display).

On the lower metering row (the active bank/layer), you will see:

AFV – the Audio Follow Video event number plus a camera icon (if the event is active).

Master – the name and colour coding of VCA or Surround VCA masters.

Link group Name – the name and colour coding of link groups.

N-1 - the name and colour coding of the N-1 bus.

Bus assignments onto the GROUP, TRACK, AUX and SUM busses. TRACK busses aresupported by Recording channels only. AUX bus assignments are colour coded to indicatepre-fader, pre-EQ (Recording channels only) or post-fader assignments.

Channel Meter – peak metering, loudness metering or both.

Gain reduction metering for the Gate, Expander, Compressor and Limiter, plus theAutomix Level. If the dynamics section or automix algorithm is enabled, then the G, E, C, Lor A letters are green.

Automix - the name and colour coding of the Automix group.

Mini display – graphical feedback on parameter values (e.g. EQ). If the processing module isturned on, then the outline of the mini display is green. If nothing is assigned to the faderstrip, then the console logo is shown.

Name or Label - the two lines display the name or label for the channels assigned to the 1stand 2nd layer fader strips. In our example, input channel 1 is assigned to the A input on layer1 (A: INP 1); there is nothing assigned to layer 2.

Source GAIN – this value displays the input gain for the channel. Note that this could bemic, line or digital gain depending on the source.

Some of the elements above can be hidden from view using the "Strip Layout" options inthe System Settings display. In addition, the number of busses shown is set by the "BayBus Count".

Touch the screen to edit the channel's VCA Master, N-1, GROUP, SUM, AUX, TRK, or Automix assignments.You can also touch the meter to change its mode and pickup point; the mini display to choose feedback on adifferent DSP module; or the source label (e.g. A: INP 1) to assign a new input source. In each case, anexpanded pop-up window appears offering the relevant options:

Bus Assign Meter Pickup Mini Display Assign

To close the pop-up, touch the X in the top right corner, touch twice in quick succession anywhere else on thedisplay, or wait 3 seconds for the window to close.


Quick Reference

Fader Strip

Each fader strip on the mc²36 provides:

1 Free Control (FC)

The Free Control (and its push button) can be assigned to any channel parameter, providinglocal control of key functions such as input gain. The default assignments can vary channel-by-channel, and may be overridden globally using the centre section's FC PRESETS. FreeControls are colour-coded, making it easy to distinguish between gain (orange), aux sends(green), EQ (blue), etc. The function and value appear briefly in a pop-up window on theChannel Display, when you touch a control.

Turn a control for fine adjustment; push down and turn for coarse adjustment.

2 A/B Input Switching

On 40-fader consoles, the left-hand channel bay includes dedicated A and B buttons. Theseswitch an input channel between its main and backup source. If no B source is assigned,then the buttons have no affect.

For fader strips without these buttons, A/B input switching can be actioned from the CentralControl Section (for the selected fader), or programmed onto user buttons (4).

3 ISO BAY & Local BANK/LAYER Switching

On 40-fader consoles, the left-hand channel bay includes the following buttons:

ISO BAY ON isolates the 16-fader section from the centre section's bank and layerswitching. This allows a second engineer to independently bank/layer switch the isolatedbay, while the main engineer has full control of the rest of the console. Isolated bays can beexcluded from snapshot loads. The AFL/PFL bus can be split to provide a second AFL/PFLoutput from the isolated bay(s) if desired.

Press BANK 1 to 6 and LAYER FLIP to switch the 16-fader bay between its six banks andupper/lower layers.

4 Fader User Buttons

These buttons are programmed from the Custom Functions display. Typical applicationsinclude mix minus control and monitor channel input switching. Four functions are available,switched by page keys on the centre section's FADER USER BUTTON panel. The defaultkey engravings reflect the upper and lower pages: either CORD and CONF, or SEND andRET.

5 Fader Strip Select (SEL)

This button selects the channel assigned to the fader strip - otherwise known as placing achannel "in access". Various operations can be performed on the channel in access,including parameter adjustment from the Central Control Section.

The name and label of the channel in access are shown in the title bar on the Central GUI (top left).


Quick Reference

6 Fader Label

This 8-character display shows the name or label of the channel assigned to the fader strip.The centre section's LABEL buttons determine which option is displayed:

CHANNEL NAME = the system name of the channel (e.g. INP 1).

USER LABEL = the user label given to the channel (e.g. GUEST).

INHERIT SOURCE = the user label given to the source which is routed to thechannel (e.g. MIC 1).

User labels for sources and DSP channels are edited from the Signal List display. Labels forcontrol channels, such as VCA masters, may be edited from the title bar on the Central GUI.The display also shows the main channel level (in dB) when a fader is touched (if the "FaderDisplay" option in the System Settings display is enabled).

7 Mute

Press the MUTE button to mute (cut) the channel.

MUTE buttons may be disabled (globally), or their position altered (from after-fader to input),using the "Mute" and "Channel Mute" options in the System Settings display.

8 Layer FLIP

Press FLIP to switch the fader strip from Layer 1 to 2, or vice versa.

9 Status LEDs

LNK - indicates if any modules within the channel are linked. Link groups provide linking ofindividual processing modules across multiple channels - for example, to link EQ sectionsbut not faders. For more details, please refer to the Operators Reference Manual.

Signal Present - the two lower LEDs light in different colours to show that signal is present.The meter point is always at the channel input. There are five possible states:

< -60dB > -60dB > -30dB > -15dB > OVR

The Overload Threshold (OVR) may be adjusted from the System Settings display.

10 Level

The 100mm fader is motorised and touch sensitive. Level may be adjusted from –128dB to+15dB.

11 AFL & PFL

Press AFL to listen to the post-fade channel signal. Press PFL to listen to the pre-fade channel signal. The listenbusses may be switched to different monitor outputs from the Central GUI's Monitoring options.

12 LAWO Backlight

The LAWO backlight is colour-coded to indicate the channel type. The colours may be customised from theChannel Config display. The defaults are: input and monitor channels = white; groups = yellow; auxes = green;VCAs = blue; sums = red.


Quick Reference

Central Control SectionThe Central Control Section provides master channel control for the selected fader:

Select a channel, by pressing its fader SEL button, and then reach out to adjust a parameter. A pop-up parameterwindow automatically appears on the Channel Display when you touch a control.

Rotary controls are colour coded, making it easy to distinguish between gain (orange), dynamics (magenta), EQ(blue), etc. Note that the controls are black (unlit) if a processing module is not supported. This could be for avariety of reasons: for example, IMAGE is not available for mono channels; not all DSP modules are supported onBroadcast channels; DSP modules may be suspended if AMBIT or Loudness metering are active.

Turn a control for fine adjustment; push down and turn for coarse adjustment.

The panel is divided into the following areas:

INPUT - input gain, microphone preamplifier settings, stereo input balance/controls and tone to channel.

DIG AMP - digital amplifier (gain); DELAY - channel delay; INSERT - insert return on/off and send level.

DIROUT – channel direct output level and mute.

IMAGE - width and positioning for a stereo channel.

DYNAMICS: independent GATE, EXPANDER, COMPRESSOR and LIMITER. Recording Channelssupport sidechain filtering (SCF) and an external KEY input.

EQUALIZER - 4-band equaliser (EQ) plus, on Recording Channels, 2-band filters (FILTER) and sidechainfilters (SCF).

PAN / HYPERPAN - multi-channel panning onto the channel’s mix bus outputs.

CHANNEL - AFL for individual modules (LISTEN TOUCH SNS), snapshot isolate (SNAP ISO), channelMUTE and channel level (FADER).

AUX SENDS - 32 aux sends; AFV - audio follows video.

Every module includes a SEL (selection) button. This can be used to copy, reset, or link modules, or selectmodules for snapshot crossfades. The SEL ALL button selects (or deselects) all modules.

Use the Couple group to quickly adjust parameters across a range of channels: press and hold thefader SEL button on the first and last channels you wish to couple - the fader SELs turn red toindicate that coupling is active. Now adjust a parameter (e.g. EQ gain) - all EQ gains across thecouple group are adjusted; any offsets are retained. To dissolve the couple, press any other fader SELbutton (outside the couple group range). This method assumes that the "Direct Couple" option in theSystem Settings display is enabled (the default).

On 40-fader consoles, you cannot couple across the entire console; coupling is permitted within theleft-hand bay (fader strips 1 to 16) or the rest of the console (fader strips 17 to 40).


Quick Reference

Central GUIThe Central GUI (Graphical User Interface) is a high resolution touch-screen providing access to the console'ssetup displays. Settings can be adjusted via the touch-screen, trackpad and mouse keys, or console keyboard.The GUI is divided into the following areas:

1 Title Bar (Headline)

Across the top you will always see the page select button, next/previous page buttons, the name and label of thechannel in access, the time (local time, timecode or integrated loudness), and the name of the current productionand snapshot. You may also see a yellow warning flag if the global alarm is triggered, or a locked icon if theconsole keyboard is locked.

2 SCREEN CONTROL displays

Various displays can appear in this area. To change display, touch the page select button (top left); use akeyboard shortcut; or press one of the dedicated buttons on the centre section's SCREEN CONTROL panel. TheNext (<-) and Previous (->) page buttons in the title bar (1), can also be used to quickly return to an earlierselection.

The Signal List display is shown above; this can be used to route any source to any destination. The MainFaders display is the usual selection during a production. This provides "Channel Display" operation for the 8central faders plus two module feedback windows for the selected channel (e.g. EQ and Dynamics).

3 Status Bar

The status bar provides feedback on the amount of used data storage space (%) and the software release version.The icons on the right indicate the status of the console PSU(s) and system connection; hover over an icon toreveal further information.

4 Touch-screen Buttons

This area is reserved for monitoring or ACCESS/ASSIGN functions. The default mode is monitoring. Press theACCESS/ASSIGN button, on the centre section's SCREEN CONTROL panel, to reveal the access/assignfunctions.

The title bar (1), status bar (3) and touch-screen buttons (4) remain visible at all times, regardless ofthe selected SCREEN CONTROL display (2).


Quick Reference

Centre SectionThe centre section provides the following master controls:

1 Central User Buttons

These buttons are programmed from the CustomFunctions display and can be customised to meet yourinstallation's needs. Typical applications include Global A/B switching, Loudness Metering Start and Reset andGlobal Tone enable. Eight buttons are available, each withits own electronic label.

2 Fader User Button PAGE Switching

This area displays the four fader user button functions, andswitches the console globally between the two pages.

3 Reveal (VCA or Surround VCA)

This button reveals VCA or Surround VCA slaves so thatyou can offset fader levels and other relative parameters.First, select the VCA or Surround VCA master (by pressingits fader SEL button). Then press REVEAL - the slavechannels automatically appear, in their predeterminedposition (as defined by the "Reveal" options in the SystemSettings display).

4 Global BANK & LAYER Switching

The 1 to 6 buttons switch the fader strips, globally,between banks. One button is always lit; this is the activebank. Six banks are available, each with its own electroniclabel. Within each bank, press FLIP to invert the layers.

The bank labels are edited from the Central GUI. Press theACCESS/ASSIGN button, on the SCREEN CONTROL panel (11), to view the ACCESS/ASSIGN functions (on theright of the GUI). Then, select the MISC tab (on-screen), and click to edit the BANK's label field.

5 Fader Control of Levels

These buttons temporarily assign another level parameter onto the console's faders. Press AUX SENDS to assignan aux send - the electronic label shows the name of the send (e.g. AUX 1). Then, use the arrow buttons to scrollthrough each aux. Alternatively, touch the aux send on the Central Control Section and then press USE TYPE -this switches the faders directly to say Aux Send 28 without scrolling. The following level parameters may becontrolled in this manner: Aux Sends (1 to 32), digital gain (DIG AMP) or INSERT SEND level. The fader labelsacross the console show the parameter name, and flash to warn you that you are now controlling something otherthan channel level!

6 Free Control Assign & Presets

The FC ASSIGN button is used to change the default Free Control assignments. Press FC ASSIGN. Then, selecta parameter by touching its rotary encoder on the Central Control Section. Then, touch the fader strip FreeControl(s) to complete your assignment(s). When you have finished, remember to deselect FC ASSIGN.

The FC PRESETs temporarily override the default assignments. These can be used to access a specificparameter globally across the console. When you deselect the preset, all Free Controls return to their defaultassignments. The first four presets are fixed: press GAIN for source gain; PAN for LCR panning; DELAY for delaytime; press AUX, and turn the rotary control, to assign an aux send from 1 to 32. The four USER presets areprogrammed as follows: select a fader strip (with the required parameter assigned to its Free Control). Then,press and hold a USER preset (1 to 4) until the button flashes - this stores the selected channel's Free Controlassignment. Now press the USER preset button quickly - the stored assignment is recalled globally across theconsole.


Quick Reference

7 Monitoring

This area is divided into two. The upper buttons select themonitor source for either CRM 1 (5.1 surround) or CRM 2(stereo). Below are the volume controls and CUT / DIM foreach monitor output. The physical controls work inconjunction with the Central GUI, and are covered in moredetail later. See Monitoring Audio.

8 Talkback

This area includes four central user buttons (ideal for globaltalkback functions) and a female XLR connector for yourengineer's talkback mic. The user buttons are programmedfrom the Custom Functions display. The XLR is wireddirectly to the TB connector on the console's rear panel.From here you can connect to an external communicationssystem (via an external talkback mic preamp), or to one ofthe console's rear panel MIC inputs (for integrated consoletalkback). If using the latter option, the mic input should bedefined as the talkback source in all user-defined CustomFunctions.

9 Label

These buttons switch the fader strip labels between thechannel system name, channel user label or inheritedsource label.

10 Production UPDATE

This button saves the current console settings into theactive production. Note that the button overwrites (updates)the active production. If new snapshots have been saved, then the button flashes as a reminder to save. For moreinformation, see Saving Settings.

11 SCREEN CONTROL

This area works in conjunction with the Central GUI:

Press the ACCESS/ASSIGN button to switch the touch-screen buttons (on the right) between monitoringand ACCESS/ASSIGN functions.

Use the SIGNAL, METER, PROD FILE and CHAN CONFIG buttons to select the associated display.Each button provides access to more than one display, so keep pressing to cycle through the options.

Once a parameter field is selected, turn the rotary control to adjust the value. When focussed on a list,such as in the Signal List display, turn the rotary control to scroll up/down to change the selection.

The left/right arrow buttons focus on a different part of the display. Keep pressing to cycle around thedisplay areas.

Press the ESC button to cancel any mode or operation - for example, to cancel out of FC ASSIGN.

Use the trackpad to move the pointer around the Central GUI - left-click to enable or disable an on-screenfunction; right-click to view additional menu options.

Installation

Frame Installation

The console is designed for table-top mounting onto a cross bar (not supplied). Note that no separate OBmounting kit is required, as mounting threads are integrated into the frame. All plug-in connectors are located onthe rear panel. Therefore, when installing, please leave enough room for the cables.

You will find full specifications and installation drawings for all frame sizes in the Appendices at the end of thismanual.

Temperature and Cooling

Proper operation of the control surface can only be guaranteed at an ambient temperature between 10°C and 35°Cand a relative humidity between 15% and 85% (not condensing). To keep the control surface cool in extremeenvironments, the front panel is fitted with low spinning fans. When relying on convection cooling, ensure that theunit’s ventilation holes are not blocked to allow air circulation.

Warning

ALWAYS observe the minimum distances around the console frame to allow for ventilation and cableducting.

Take care that no devices or cables obstruct the flow of air thereby hindering cooling.

The Console Keyboard

The console is supplied with a wired USB keyboard (either English or German). On larger frames, the keyboardsits on top of the console surface. On 16-fader frames, the keyboard is floating and should be connected to one ofthe front buffer USB ports.

If you change the console keyboard, from English to German or vice versa, then you will need to update the

keyboard driver. Details can be found in the separate document: "mc236 Service Instructions".


Installation

SFP Module InstallationIn order to use the console's rear MADI port, an optical fibre SFP transceiver must be fitted. The SFP moduledetermines the type of optical fibre connection.

Rear MADI Port (Dust Cap Fitted) Plug-in SFP Module

The following transceivers can be specified at the time of order and delivered with your console:

981/60-80 - for MADI multi-mode fibre

981/60-81 - for MADI single-mode fibre

For more details, please refer to the module's data sheet.

The SFP transceiver is hot-pluggable. To install, remove the dust caps from both the rear MADI port and the SFPmodule. Then, push the module into the rectangular MADI slot. Press gently and firmly until the module locks intoposition.

Warning

CAUTION: Please unlock the transceiver before removing to avoid mechanical damage to the slot.

If the transceiver is removed, please refit the MADI port dust cap to protect the internal components.


Installation

Grounding & Power

Grounding

The console is grounded via the 3-pin IEC MAINS connectors at the rear of the frame. However, for EMC reasons,you may wish to establish an additional ground as follows. Fasten the grounding cable to the CASE groundingbolt (M5 x 12) using a Torx T25 driver:

For compliance with AES3, external digital interfaces should also be connected to a field ground.

Warning

The control surface must be on the same potential as all other system devices/modules.

For Scandinavian countries, ALWAYS use a grounded mains connection, to prevent the device frombeing grounded through Ethernet or other signal connections.

Power

The console is fitted with two independent power supplies running in parallel. Only one supply is required tooperate the system. For redundancy, connect both supplies, each to a separate AC mains circuit. This willensure continued operation if one of the mains circuits fails.

16-fader 24-fader 40-fader

Power Consumption(max)

370 W per mains 440 W per mains 520 W per mains

Current (max) 3.7 to 1.6 A 4.4 to 1.9 A (936/16)5.2 to 2.2 A

Input Voltage auto-sensing 100 to 240 VAC (PFC) / 47 to 63 Hz

Connection 2 x IEC power connectors

The two MAINS connectors are located at the rear of the frame. There is no on/off switch, and so the console willstart automatically when power is supplied. For redundancy, run each connector from a separate phase of the ACsupply. It is recommended that you install a master power switch to control both supplies.

Warning

The console MUST be connected to the mains using the IEC power cables supplied with the system.Country-specific mains adaptors will be supplied.

When running with multiple mains supplies, make sure that both circuits lie on the same groundpotential. Otherwise, an internal bridge of two ground wires will lead to a ground loop!

The MAINS connectors include an IEC locking mechanism. Please unlock beforeremoving a connector. Be sure to turn the mains power off BEFORE connecting ordisconnecting the power cables.


Installation

Powering On & Checking the SystemThe console starts automatically when power is supplied to either of the MAINS connections.

The control system boots in a few seconds; during this time you will see the boot-up progress on the console'sdisplays. When boot-up is complete, the displays refresh to show the Channel Display and Central GUI screensThe console is now ready for operation:

The console can be booted before any Compact IO stageboxes. This enables you to preparesettings, including signal routing, before remote stageboxes are connected or have received power.

Checking the System Components

At this stage, it is a good idea to check the status of all system components. In the event of a failure, a hazardwarning flag (the global alarm) appears in the title bar of the Central GUI:

To interrogate further, press the SIGNAL button, located on the SCREEN CONTROL panel, to view the SignalSettings display. A red/white cross in the System tree, and a red highlighted component, shows the location ofthe problem. If the fault is hidden, follow the red crosses in the System tree to reveal the problem. In our example,there is a Compact IO stagebox which is not yet connected:

Once the fault is rectified, all components appear in grey and the global alarm clears.

The status of the internal PSUs is shown on the Central GUI (in the Status Bar). Hover your cursorover the PSU icon for more information.

For details on servicing components, please refer to the separate document: "mc236 Service Instructions".


Installation

Signal ConnectionsYou should connect all external audio, network and reference signals at the rear of the console:

1 Analogue & Digital Monitoring (XLR)

LINE OUT 1 to 8 and AES OUT 1 to 4 are reserved for monitoring.

Two independent monitor outputs are supported: CRM 1 (5.1 surround) and CRM 2 (stereo). In each case, youmay connect either an analogue or digital loudspeaker system. The XLRs are labelled L/R, C/LFE and LS/RS toguide you. If you wish to use stereo main monitoring, then simply connect the CRM 1 L/R outputs and leave theother outputs free. Note that the Monitoring User Buttons on the Central GUI determine which outputs are active:analogue Line or digital AES.

For digital main monitoring, connect your speaker system to AES OUT 1 to 3.

Or, for analogue main monitoring, connect your loudspeakers to LINE OUT 1 to 6.

For digital secondary monitoring, connect your speaker system to AES OUT 4.

Or, for analogue secondary monitoring, connect your loudspeakers to LINE OUT 7 & 8.

2 External Mic, Line and AES Devices (XLR)

The remaining AES IN/OUT, LINE OUT and MIC IN connectors are free for external devices such asmicrophones, outboard effects, playback machines and external metering. They comprise 8 AES IN (1-8); 4 AESOUT (5-8); 24 LINE OUT (9-32); 32 MIC IN (1-32*). *Note that MIC IN 32 may be reserved for talkback.

All XLR connections are electronically balanced.

AES INs and OUTs conform to the stereo AES 3 standard.

For LINE OUTs, the maximum analogue level can be adjusted to+12, +15, +18, +21 or +24 dBu relative to digital full scale(dBFS). This is a factory-configured setting; +24dBu isrecommended.

Each of the 32 MIC INs features a discrete class-A preamplifierwith superb performance at both low (mic) and high (line) levels.In addition to variable gain, each input comes with switchablephantom power, a high-pass filter and 20dB PAD. The maximumanalogue input level (with the PAD enabled) is +24dBu.


Installation

3 MADI (optical fibre via SFP Module)

The console's MADI port carries up to 64 input and output channels. It is ideal for connecting a multitrack recorderor external multi-channel device. The connection conforms to AES 10 and is available on optical fibre LCconnectors, once you have fitted the recommended SFP module. The LOCK / ERR LED indicates the status ofthe MADI link: green = active; flashing red = link is asynchronous; off = no connection or link is invalid.

4 GPIO (D-Sub)

The GPIO connector provides 8 General Purpose Inputs and Outputs. Their functions are programmed from theCustom Functions display, and typical applications include fader starts, red light switching, etc. A wiringdiagram for the D-Sub connector is included in the Appendices at the end of this manual.

5 ETHERNET A & B (CAT 5)

The ETHERNET B port provides a network connection to the mc236 control system. You can use this to connectan external computer (for remote control, configuration and service), a third-party controlling device, or anotherLawo system (to support audio networking). A single device may connect directly. However, more commonly, anetwork switch is installed. Connections are made using standard CAT 5/6/7 Gigabit Ethernet, RJ45 connectors,crossed or straight (1:1) cable, up to 100m. Please see the Ethernet B topic for more details.

In this release, the ETHERNET A port (internal network) is unused.

6 RAVENNA / AES67 (CAT 5)

Each of the three RAVENNA ports provides an Audio-over-IP interface (conforming to the RAVENNA Link 1.0

standard). These can connect either to a Compact I/O stagebox, or to another mc2 system, as defined by theAdminHD configuration. Connections are made using standard CAT 5/6/7 Gigabit Ethernet, RJ45 connectors,crossed or straight (1:1) cable, up to 100m. Each link provides 128 bi-directional channels (at 48kHz).

RAVENNA links should be directly wired. Providing the correct RAVENNA port is connected (to match theAdminHD configuration), the interface is self-configuring. Once you have connected the ports (e.g. from Consoleto Compact I/O), no further network configuration is necessary.

Warning

To guarantee low latency, reliability and easy setup, do NOT connect any other network equipmentbetween the RAVENNA links.

7 CLOCK IN & OUT (BNC)

The CLOCK IN can be used to connect an external sync reference. The input accepts Wordclock, Video BlackBurst (PAL or NTSC) or AES 3-id. Tri-level sync is not supported. When running the system referenced toWordclock, the frequency of the sync source MUST match the internal operating sample rate of the system. Thesync signal priorities are defined using the "Wordclock" options in the System Settings display.

The CLOCK OUT provides a Wordclock out, following the system sampling rate.

Both connections use a standard BNC video connector.

8 TB - TALKBACK (XLR)

This connector is wired directly from the TALKBACK XLR on the console's front panel. It can connect either to anexternal communications system, or to one of the console's MIC inputs (e.g. MIC IN 32). Your chosen inputshould be selected as the talkback source when programming talkback functions from the Custom Functionsdisplay. If you are using an external communications system, then an external microphone preamplifier will berequired (as the TB connector is simply wired through from the front panel XLR).


Installation

Reference Settings (System Clock)The Wordclock options (in the System Settings display) define the console's sample rate and sync reference.

Select this display by clicking on the page button (at the top right of the Central GUI), and selecting System ->System Settings. Then select the Word clock topic (on the left):

Sample Rate

The Max Sample Rate field is for display purposes only, and shows the highest sample rate available (either 48or 96 kHz). The Sample Rate option will change the operating frequency of the console (for example, 48kHz or44.1kHz).

Warning

It is NOT recommended to change the sample rate unless you wish to lock to an external Wordclockreference signal. If this is the case, then the frequency of the sync source MUST match the SampleRate option.

You should mute your loudspeakers when changing the Sample Rate option.

Sync Source

The Source Priority 1 & 2 fields define the main and redundant clock source. If sync is lost or a signal of anincorrect frequency appears on Source Priority 1, the system automatically switches to Source Priority 2.Similarly, if sync is lost on Source Priority 2, the system automatically switches to internal sync.

You can set each of the Source Priority options to:

Input 1 – signal connected to the CLOCK IN connector (on the console's rear panel).

Input 2 – not supported on the mc236.

MultiCh - Multichannel Sync (MADI). This option must be configured using AdminHD.

The Active Synchronization Source displays (and can override) the active source for the system:

Src Prio 1 – the input selected as Source Priority 1.

Src Prio 2 – the input selected as Source Priority 2.

Internal.

When enabled, the Return Mode forces the system to switch back to Source Priority 1 (or 2) when it returns.The system checks whether the return sync is valid and will not switch until the sync source matches the chosenoperating frequency of the console.

When enabled, the Alarm on Internal activates the global alarm if the system switches to internal sync.

The five fields at the bottom of the display show the type of signal detected (e.g. Wordclock) and its status (OK).


Installation

In Practice..

On the mc236, there are two possible modes of operation: sync to an external reference (CLOCK IN), and sync tointernal (the console's internal generator).

Sync to External

First, connect your reference signal to the CLOCK IN on the console's rear panel. The Input 1 Signal and Input1 State fields should update to show the type of signal and its status (OK). If using a Wordclock signal, thencheck that the frequency of the sync source matches the Sample Rate option

Next, click on the Source Priority 1 field and select Input 1. Then click on the Source Priority 2 field and alsoselect Input 1. This defines the CLOCK IN signal as the main (and redundant) clock source.

If there should be a problem with the external reference, then the system will automatically switch to internalsync.

Enable the Return mode option if you wish the system to instigate an automatic return to the external reference(once the signal is reconnected and valid).

Sync to Internal

First, deactivate the Return Mode option, to prevent any automatic switching to external sync inputs.

Then, click on the Active Synchronization Source option and select Internal.

In this mode, it is recommended that you disable the Alarm on Internal option. Otherwise the global alarm willalways be on.


Installation

Ethernet B (External Network)

The ETHERNET B port provides a network connection to the mc236 control system. It supports a variety ofapplications including:

Remote control and configuration from an external computer running Lawo's mxGUI and AdminHD.

Remote control from a third-party device (via Lawo's Remote MNOPL)

Remote diagnostics and maintenance via the Web Browser Interface and Telnet sessions.

Network connections to other Lawo systems, to support audio networking.

Remote maintenance from Lawo's service department via the optional dial-up router.

A single device may connect directly. However, more commonly, a network switch is installed:

Connections are made using standard CAT 5/6/7 Gigabit Ethernet, RJ45 connectors, crossed or straight (1:1)cable, up to 100m.

Using a suitable network cable, connect the Ethernet B port on the console's rear panel (ETH B EXT.) to yourcomputer's network interface card (either directly, or via a Network Switch as shown above).

Depending on the number of network connections, one console is able to support up to 16 clientssimultaneously.

For more information on installing a suitable network switch, please contact your local Lawo representative oremail [email protected].

Warning

You must use a network switch and NOT a hub, and keep the Lawo network separate from othernetwork traffic within the installation.

Installation

TCP/IP ConfigurationTo establish communication, you will need to configure the TCP/IP settings for your computer’s network interfacecard. The following screenshots demonstrate how to do so on a computer running Windows 7 and Mac OS X:

IP Address

The IP address of your computer’s network interface card must be unique, and set within the same range as thatof the mc²36 control system. You can check the IP address of your control system from the Central GUI (usingthe Signal Settings display). For example, if your Lawo system's IP address = 192.168.102.36, then set yourcomputer's IP address to 192.168.102.101. In a networked installation, it is likely that you will be connecting viaan Ethernet switch, so please consult your network administrator for further details.

Check the address carefully. If there is an IP conflict, then the console may not operate correctly.

Subnet Mask

The Subnet Mask should be identical to that of the system. The default Subnet Mask is 255.255.255.0.

Checking Network Communication

Open your browser software, and enter the IP address of the mc²36 control system into the URL field - the WebBrowser Interface home page should appear.


Operation

OperationThis chapter covers the operating principles of the mc236 and guides you through some common operations. Theobjective is not to teach every single detail, but to introduce the basics. For more in depth knowledge, please referto the Operators Reference Manual. Please also refer to the Quick Reference guides, earlier in this manual, for anoverview of each control area.

The topics covered here are:

Working with the Central GUI

Loading a Production

Interrogating the Fader Strips

Assigning an Input Source

Adjusting Input Gain

Checking Bus Assignments

Monitoring Audio

Creating Your Own Configuration

The Signal List Display

Assigning Channels to Fader Strips

Saving Settings & Next Steps


Operation

Working with the Central GUIThere are four different ways to navigate around the Central GUI and make selections:

1. Touch-Screen

Anything which is a button or menu option can be selected by touching the screen. Buttons change colour whenenabled (e.g. Monitor Centre Cut). List selections are highlighted in black (e.g. snapshot0001):

2. Trackpad & Mouse Keys

On the SCREEN CONTROL panel, use the trackpad to position the cursor andpress the left mouse key, or double-tap on the trackpad, to make a selection. Thetrackpad includes a scroll bar (on the right). Additional functions appear if you right-click on a selection (using the right mouse key).

3. Rotary Control & Left/Right Navigation Buttons

When focussed on a list, turn the rotary control on the SCREEN CONTROL panelto scroll up/down and make a selection. You can tell which part of the display is "in focus" by the yellow text (inour example, the Snapshots list).

The Left/Right arrow buttons move the focus to a different part of the display. Press the Right arrow to moveclockwise, and the Left arrow to move anti-clockwise. Keep pressing to cycle around the display.

4. Console Keyboard

You can also use keyboard shortcuts ("Hot Keys") to move around the display and make selections:

[TAB] or [SHIFT] + [TAB] - changes the focus area.

[Cursor Up]/ [Cursor Down] - scrolls up or down entries in a list.


Operation

Changing the SCREEN CONTROL Display

Various displays can appear in the main working area of the GUI. One isalways active and its name is shown in the title bar.

There are several ways to change the display: select the on-screen Pagebutton (top left) followed by a drop-down option; use a keyboard shortcut(they are listed beside each page option); or press one of the dedicatedbuttons on the SCREEN CONTROL panel: SIGNAL, METER, PROD FILEor CHAN CONFIG. Each button provides access to more than one display,so keep pressing to cycle through the available pages. The on-screen Nextand Previous Page buttons (top left) can also be used to quickly return tothe last viewed page.

A list of all SCREEN CONTROL displays, and their function, is included in the Appendices at the end of thismanual. For more information on a specific display, please refer to the Operators Reference Manual.

The Main Faders Display

This is the usual selection during a production, as it provides "Channel Display" operation for the 8 central fadersplus two module feedback windows for the selected channel (e.g. Compressor and EQ). To select the display,press the METER button on the SCREEN CONTROL panel - you may need to press more than once to cyclethrough the other metering pages:

ACCESS/ASSIGN Functions

The ACCESS/ASSIGN button, on the SCREEN CONTROL panel, switches the right of the GUI from Monitoringto Access/Assign (plus MISC and COPY/RESET) functions. You will need these buttons to perform assignmentoperations such as fader strip assign, bus assign, copy/reset of channel parameters, etc.

De-select the ACCESS/ASSIGN button to return to the Monitoring functions.


Operation

Loading a ProductionBy default, the console's warm start data is loaded at the end of boot-up. This means that the system comesback exactly as it was when you last shut down, ensuring fast recovery of all previous settings following a loss ofpower. Depending on who was last using the console, you may be sat in front of a fully configured control surfacewith DSP settings or a series of blank fader strips! In either case, the fastest way to reset the console is to load aproduction.

Productions form the top level for user data storage and store all the settings required for a production or type ofjob.

On the mc236, you can choose to load an existing production (from the Productions List display), or start afresh

by loading a Production Template. A wide range of templates are delivered with the mc236 release. Theseconfigure the DSP resources, make default routing assignments (source to channel to bus to output), and assignthe console's fader strips; all other settings are reset (to flat or to the factory defaults). You should load atemplate to reset the console to a known a starting point. Then save your own settings into a user production(from the Productions List display).

To load a production template:

Press the PROD FILE button, located on the SCREEN CONTROL panel, to view the Production Templatesdisplay. Select a template from the list - the Properties area offers a description so that you can clarify thecontents before loading:

Each template is named with an index number to identify the DSP configuration (e.g. 2.53), and defines theconsole's Format (Stereo or 5.1); DSP channel Mode (Recording or Broadcast); how many DSP Cards are inuse (1 or 2); and the maximum number of Input, Monitor return, Group, Aux and Sum channels. The channelnumbers are described as x/y, where x = the number of full processing channels and y = the number of tinychannels (reduced processing). Note that if only one DSP card is in use, then the system is operating with DSPredundancy; the spare card will automatically takeover in the event of a failure.

To simplify the selection, templates are divided into Stereo/Surround (Recording channels), Stereo/Surround -High Availability (Broadcast channels with DSP redundancy) and Stereo/Surround - High Channel Count(Broadcast channels, no DSP redundancy). To work in 5.1, choose any Surround template. For DSPredundancy, choose a High Availability template. For more details on the differences between Broadcast andRecording channels, see Introducing the mc36.

When ready, press Load as New Production to load the current selection - the console resets accordingly. Foradditional confirmation, watch the status bar at the bottom of the Central GUI; you should see a loading…message as the production data loads:


Operation

Interrogating the Fader Strips

You can interrogate which channels have been assigned to the control surface bylooking at the fader strip label displays (below), or the Channel display (opposite):

You will see the channel name (e.g. INP x), channel label OR inherited sourcelabel depending on the centre section LABEL buttons. The Channel display alsoshows metering, bus assignments, group masters, N-1 assignments, AFV, etc.

In addition, the LAWO backlights, at the bottom of each fader strip, are colourcoded to provide quick channel indentification. The default colours are input andmonitor channels (white); groups (yellow), aux masters (green), VCAs (blue) andsums (red):

If button-glow is enabled, then fader strip buttons in their off state are dimly litaccording to the channel colour. This makes channel identification even easier,especially in low-light conditions.

Use the fader strip FLIP buttons, or the global BANK/LAYER buttons to interrogateother fader banks and layers.


Operation

Assigning an Input SourceOn input channels, you can assign any source connected to the console's routing matrix. This can be a localsource (from the Rear Connector Panel), or a remote source (from a Compact IO stagebox or networked Lawosystem). The simplest way to assign a new source is from the Channel Display touch-screen:

Touch the channel's source label at the bottom of the display (e.g. A: INP 1), and then select a directory,subdirectory and input - for example: Local I/O -> Mic -> Mic 01. Note that sources are listed using both theirsystem name and user label - System name / User Label:

Check the assignment by pressing the INHERIT SOURCE LABEL button (in the centre section), to view sourcelabels globally across the console:

This method can be used to assign each of the following channel inputs: A Input - the main channel input; BInput - the alternate channel input, switched by the INPUT B button on the Central Control Section; InsertReturn - switched by the INSERT ON button on the Central Control Section. In each case, the directories andsubdirectories provide access to the following source options:

Bus Out - the bus outputs from the console (Auxes, Groups and Sums).

Direct Out - the direct output from any other channel.

Insert Send - the insert send from any other channel.

Local IO - external sources connected to the Rear Connector Panel.

Ra-Link - external sources connected to a Compact IO stagebox (optional).

Generator - the internal signal generator (two sine wave, one pink noise and one white noise output).

To disconnect the source from a channel, select Disconnect.

Sources can also be assigned to channels from the Central GUI's Signal List display. The Signal List providestools for assigning consecutive inputs to consecutive channels, editing source labels, etc.


Operation

Adjusting Input GainInput gain can be adjusted from either the fader strip or Central Control Section:

Fader Strip Central Control Section

Fader Strip: Input Gain

The upper rotary control on the channel fader strip is, by default, assigned to source gain - either mic/line ordigital depending on the channel's source. The amount of GAIN is shown on the Channel display.

Central Control Section: INPUT Control

For additional parameters, such as 48V, high-pass filter or the 20dB PAD, assign the channel to the CentralControl Section by pressing its fader SEL button. You can also switch the channel between its A and B inputs, ordeal with problem stereo inputs using Left to Both, Right to Both, Left/Right reverse.

Input Metering

The Signal Present LEDs beside the fader always meter the channelinput, while the meter on the Channel Display may be switched todifferent positions: input, pre-fader, post-fader, etc. Touch the meter toselect an option for the Peak meter Pickup point. If you select Input,then you will see the level immediately after the source gain and beforeall signal processing.


Operation

Checking Bus AssignmentsThe Channel Display shows the bus assignments onto the GROUP, TRACK, AUX and SUM busses.

TRACK busses are supported by Recording channels only. AUX bus assignmentsare colour coded to indicate pre-fader (e.g. Aux 9, 13, 14), pre-EQ (Recordingchannels only) or post-fader assignments (e.g. Aux 11, 12). The number of bussesshown is set by the "Bay Bus Count" options in the System Settings display.

The production template configures the default bus formats. So, for example, Sums 1to 8 are defined either as four stereo Sums (1/2, 3/4, 5/6, 7/8), or one 5.1 and onestereo (Sums 1 to 6; 7/8). These formats can be modified later, from the Signal Listdisplay, if you wish.

Each number on the display represents a mono bus. So, for a 5.1 Sum, you will seeall six individual assignments: SUM 1 = Left; SUM 2 = Right; SUM 3 = Centre; SUM4 = LFE; SUM 5 = Surround Left; SUM 6 = Surround Right.

Touch the screen, within one of the bus areas, to edit the assignments - anexpanded pop-up window appears. Now touch the numbers to enable (or disable) anassignment. Note that when you make an assignment onto a stereo or surroundbus, the console assumes you wish to route to all outputs (e.g. to all six Sums). Ifthis is not the case, then you can deselect an individual assignment - for example,touch Sum 3 to remove the channel from the Centre Sum.

For simplicity at this stage, you should check that all channels are assigned to SUM 1 to 6 (if working in 5.1) orSUM 1 & 2 (if working in stereo). This ensures that once channel panning is turned ON, you will benefit from full 5-channel surround, or stereo, panning.

In addition to viewing bus assignments from individual channels, you can reverse interrogate an output as follows.Select the Busses Reverse display, by choosing Busses -> Busses Reverse from the Central GUI Page selectbutton. Then select a bus master by pressing its fader SEL button - for example, select SUM 1/2 if working instereo, or SURR 217 (the Surround master of SUMs 1 to 6) if working in surround. The display now shows allassignments to the channel in access - in our example, INP channels 1 to 24 are assigned to SUM 1:

You can touch the coloured buttons to remove an assignment. Or, select Show All to reveal all available sourcechannels. Then touch the grey "unassigned" buttons to make assignments onto Sum 1:


Operation

Monitoring AudioThe console provides two monitor outputs with independent source selection, volume, cut and dim. CRM 1supports 5.1 surround, while CRM 2 is stereo. In each case, you may connect either an analogue or digitalloudspeaker system from the Rear Panel. The stereo headphone output, located on the front buffer, can followeither monitor source selector and has its own output level. The principal controls can be found on the centresection's MONITORING panel, with additional functions on the right of the Central GUI.

Monitor Source Selection

Under MONITORING SOURCES, press either CRM 1, or CRM 2, to select a source for the main, or secondary,loudspeakers. The first eight buttons are factory-configured to select various Sum, Group or Aux busses. ForCRM 1, read the black text on white engravings. For CRM 2, read the white text on black engravings. The USER 1to 8 buttons can be assigned to any source and are electronically labelled. If no source is assigned to a button,then the label shows no asgn. The buttons are programmed from the Central GUI Monitoring User Buttons.

Volume, CUT and DIM

Under CONTROL ROOM, use the upper and lower rotary controls to adjust the main and secondary loudspeakervolumes. The accompanying buttons will CUT or DIM each monitor output; the amount of dim defaults to 20dB.

Each monitor output can be assigned to either its analogue or digital outputs. Therefore, if you are nothearing anything, check your connections and the Speaker assignment (made from the Central GUIMonitoring User Buttons).

Central GUI Monitoring Functions

The on-screen functions are divided into two areas: Monitoring and User Buttons.

In the Monitoring area, use the two tabs to switch between the main (CRM 1) and secondary (CRM 2) monitoroutputs. From here you can cut an individual loudspeaker (L, C, R, Ls, Rs and LFE); mono the monitoring (M);assign left or right to both front speakers (LtoB, RtoB); reverse the phase of a front speaker (Ph L, Ph R); reducethe volume (DIM); or activate ALT (alternate monitoring). The SET button allows you to adjust the dim level,stereo balance, etc. For example, press SET followed by DIM and then turn the CTRL ROOM 1 rotary control -the electronic label shows that you are now adjusting the Dim level and its new value. When you have finished,remember to deselect the SET button!


Operation

The nine User Buttons perform the following functions:

Assign - assigns sources to the USER 1 to 8 buttons (on the MONITORING SOURCES panel).

Speaker - assigns each monitor output to its analogue or digital connections.

HP - adjusts options for the Headphone output.

PFL/AFL to CRM - assign the AFL and PFL busses to the CRM outputs.

To programme the USER Buttons (on the MONITORING SOURCES panel)

Select the channel routed from the source you wish to assign, by pressing its fader SEL button. Note that thechannel format (mono, stereo or surround) will determine the monitor source assignment (1, 2 or 6-channel). Next,touch the on-screen Assign button - the text "Access to CRM Sel" appears. Then, select one of the USER 1 to 8buttons on the MONITORING SOURCES panel. The assignment is made and the electronic label updates. TheUSER button assignments are stored in the production.

To change the Speaker assignments (to analogue or digital outputs)

Select the monitor output you wish to assign, by selecting either the CRM 1 or CRM 2tab. Then, touch the on-screen Speaker button - the options Unlock, Line and AES3appear. The current speaker assignment, Line for analogue or AES3 for digital, ishighlighted in red. Note that if both Line and AES3 are yellow, then neither of the rearpanel connections are active. In our example, CRM 1 is currently assigned to AES3outputs 1-3. For safety, the assignment is "locked". To change it, first select theUnlock button, followed by the new output - e.g. Line 1-6. The Speaker assignmentsare stored in the production.

To adjust the Headphone Monitor Source and Level

Select the on-screen HP button. Then, select either CRM 1 or CRM 2 so that the headphone output follows one ofthe monitor source selectors. To adjust the independent headphone volume, select Set Lvl and then turn theCTRL ROOM 1 rotary control on the front panel - the electronic label updates to show that it is now Headphonelevel which is being adjusted:


Operation

AFL & PFL

The surround AFL and stereo PFL busses may be switched to either the CRM 1 or CRM 2 outputs.

From the Central GUI, select the monitor output you wish to assign, by selecting either the CRM 1 or CRM 2 tab.Then, touch the on-screen PFL to CRM and/or AFL to CRM buttons. Select both options if you wish to hear AFLand PFL on the same speakers.

AFL to CRM 1 PFL to CRM 2 AFL & PFL to CRM 1

The PFL/AFL CLEAR button, on the front panel, illuminates if any AFL or PFL selections are active.Press the button to quickly clear all active selections.


Operation

Creating Your Own ConfigurationIf the production template contains all the connections and fader strip assignments you need, then you are readyto mix!

Please refer to the Fader Strip and Central Control Section quick reference guides for more details. You can usethese areas to adjust any channel parameter - level, mute, AFL, PFL, EQ, Dynamics, Delay, Aux sends, etc.

Alternatively, you may want to modify the configuration to suit your particular show or mix. You can perform theseoperations in any order, but the most efficient way is as follows:

Configure signal routing, user labels and channel formats – from the Signal List display, you canlabel signals and configure signal routing. You can also choose which input channels, groups, sums, etc.need to be mono, stereo or surround.

Assign your channels to fader strips – design your console layout by assigning your input channels,groups, sums, etc. where you want them.


Operation

The Signal List DisplayFrom the Signal List display, you can configure signal routing and edit user labels. You can also choose whichinput channels, groups, sums, etc. need to be mono, stereo or surround. Press the SIGNAL button, located onthe SCREEN CONTROL panel, to view the Signal List display. The display shows connections from Sources (onthe left) to Destinations (on the right). To keep the list manageable, sources and destinations are divided intoDirectories and Subdirectories. Signals which are connected are indicated by a red/white cross:

To route a source to an input channel:

Select a source – e.g. Local I/O (Directory) -> Mic (Subdirectory) -> Mic 28. Then select the destination – e.g.Input/Mon A + B (Directory) -> A Inp 1 (Subdirectory) -> INP 28A. Note that input channels support an A/B inputswitch, hence you will see both A and B INP Subdirectories.

Then press the on-screen CONNECT button to make the connection - the Signal List updates with a linebetween the source and destination. If the input channel is already assigned to a fader strip, and INHERITSOURCE is selected (from the centre section LABEL buttons), then you will see the source label in the faderstrip's label display. You will also see signal present beside the fader, and metering on the Channel display(according to the meter pickup point).

To route consecutive sources to consecutive channels:

Follow the steps above, but BEFORE you press CONNECT, enable the on-screen Step mode. This time whenyou press CONNECT, the route is made, and both the source and destination selections automatically step downto the next entries in the list. Continue pressing CONNECT until all of your sources are connected to yourdestinations.

If the list of sources is shorter than the list of destinations, then when you reach the last source in the list, Stepmode automatically scrolls back up to the first source in the list. Step mode can be used with an offset betweenthe starting source and destination: for example, to route Microphones 1-16 to Input Channels 17-32.

To remove a route:

Select the destination (e.g. INP 28A), and press DISCONNECT - the line between the source and destinationdisappears.


Operation

Editing User Labels

The user Label for each source and destination may be edited from the Signal List, and is stored and recalledby both snapshots and productions:

Note that the source and destination Name is defined by the AdminHD configuration, and cannot beedited from the Central GUI. This provides a fixed Name, relevant to the installation, which remainsconsistent for all users.

The centre section LABEL buttons control what is displayed on the fader strip. For input and monitor DSPchannels, use the Source Label field to edit your source labels, and the Destination Label field to edit thechannel user labels.

To edit a label:

Click on the label field - either once to select all existing text (white) or twice (black cursor) to modify the existingname. Then enter a new name from the keyboard. Press Enter, on the keyboard, to confirm the new name. Or, ifyou make a mistake or want to exit without making any changes, press ESC.

Turn on Easy Edit mode to speed up the labelling process. This mode carries forward your text, sothat you can quickly enter the same label for multiple signals. Or, if the label ends with a number,then the number will increment.

BEFORE editing your first source or destination label, turn onEasy Edit at the bottom of the Signal List display. Then selectand edit your first source or destination label in the usual manner -e.g. Mic 1. Then press Enter, on the keyboard, to confirm - thesystem automatically steps down to the next signal in the list,and the text label is copied. If the text ends with a number, thenthe number increments. If the label does not end with a number,then the same text is carried into the next label field. When youhave entered the last label, press the ESC button on thekeyboard, to exit the labelling mode.

Note that you can temporarily enable Easy Edit using the console keyboard SHIFT button as follows. Select thefirst signal label and enter a new label in the usual manner. Then press and hold SHIFT and then press Enter onthe keyboard - the system automatically steps down to the next signal in the list, and the text label is copied.Keep holding SHIFT and pressing Enter until you have labelled all the required fields. Then press ESC to exit thelabelling mode.


Operation

Changing Channel Formats

Any odd/even pair of input or output channels may be configured for stereo and controlled from a single fader strip.Or, multiple channels may be configured for surround (up to 8-channel) and controlled from a single Surround VCAmaster.

To create a stereo input channel:

1. Select an odd numbered input channel from the Destinations list (e.g. INP 7).

2. Press the STEREO soft key, or right-click and select the Stereo option:

This links the selected channel to its adjacent DSP path. For example, INP 7 and INP 8.

You can link any odd/even pair of input or monitor channels using this method. Alternatively, select a Bus Outfrom the Sources list to create a stereo bus master.

To create a surround sum:

1. Select the first sum for the surround output from the Sources list (e.g. SUM 1).

2. Press the SURROUND soft key, or right-click and select the Surround option:

This links consecutive sums, according to the global surround format, and automatically assigns a SurroundVCA - in our example, SURR 217.

You can configure surround sums, groups or auxes using this method. Alternatively, select InputMon from theSources list to configure surround input or monitor channels.

For surround inputs, panning is automatically reset so that INP 9 feeds SUM 1, INP 10 feeds SUM 2, etc. Thebest way to position a surround channel within the surround field is using Hyper Pan.

Surround channels may only be created in 8-channel blocks, so you must select Sum 1, 9, 17, etc.You cannot select Surround if you right-click on an invalid channel number.

Note that the front and rear left/right pairs of a surround channel are automatically linked for stereo. This is forconvenience when revealing the component channels. The stereo linking is only a default state; you can deselectthe stereo link at any time.


Operation

Assigning Channels to Fader StripsHaving made some new connections, you may want to re-assign the console's fader strips.You can use the following method to assign any input or monitor channel, group, sum,aux, VCA or Surround VCA to any fader strip.

To assign a single channel to a fader strip:

First, put the channel into access - you can do this either by pressing its fader SEL button(if the channel is already assigned to the surface), or using the ACCESS/ASSIGN touch-screen panel as follows:

1. On the SCREEN CONTROL front panel, press the ACCESS/ASSIGN button toswitch the right of the Central GUI from Monitoring to Access/Assign functions:

2. Enter the channel type - e.g. INP for input channels - the button flashes.

3. Enter the channel number from the numeric keypad - e.g. press 2, 5 and ENTERfor the number twenty five.

The channel in access is shown in the ACCESS/ASSIGN display. If you enter an invalidselection, the display tells you by flashing the letters NOTAVAIL for ‘Not Available’. PressESC to exit the operation and start again.

With the correct channel in access, select the on-screen STRIP ASSIGN button (shownopposite) - the fader SEL buttons across the console flash, in green:

Press a fader SEL to complete the assignment - the fader strip updates and the SEL button changes colour, fromgreen to red. Deselect the on-screen STRIP ASSIGN button, or press ESC, to exit the strip assignment mode.

To assign a range of channels to consecutive fader strips:

Repeat the steps above to put the first channel into access - e.g INP 1. Then select the on-screen FIRST LASTbutton (instead of STRIP ASSIGN). This time press the fader SEL on the first fader you wish to assign (e.g. strip1) followed by the fader SEL on the last fader (e.g. strip 24) - the console incrementally assigns channels fromfader strip 1 to 24, and then cancels the FIRST LAST mode.

If all the channels are mono, then you will have assigned INP 1 to 24 to fader strips 1 to 24. If some channels arestereo, then they are automatically assigned to a single fader. For example, if INP 1&2 and INP 3&4 are stereo,then they are assigned to fader strips 1 and 2; INP 5 is assigned to fader strip 3, INP 6 to fader strip 4, and soon. If some channels are surround, then it is the component channels which are assigned (e.g. L/R to fader strip1, C to fader strip 2, LFE to fader strip 3, Ls/Rs to fader strip 4). You can control surround channels from a singlemaster (called a Surround VCA), but this must be assigned to the control surface separately.

The start and end of the range can be at any position across the control surface, and sources may be routed fromleft to right or from right to left by reversing the order of your first and last fader selection.

On 40-fader consoles, you cannot use FIRST LAST across the entire console; first/last selectionsare permitted within the left-hand bay (strips 1 to 16) or the rest of the console (strips 17 to 40).


Operation

Saving Settings & Next StepsAt any time you can save the current settings of the console into a new production using the Save button (on theProduction List display).

Save keeps all the current settings, including any snapshot folders, and saves them under a new productionname. (i.e. this operation performs a "Save As..".)

Note that New will clear all snapshots and folders and create an empty directory. Therefore, to start with anempty snapshots page, select New before saving.

First, select the Production List display by pressing the PROD/FILE button located on the SCREEN CONTROLpanel. Then select the on-screen Save button - the current settings are saved into a new production which isgiven a default name (e.g. production 0012):

The production is time and date stamped, and automatically becomes the active production (A) as indicated inthe title bar. For additional confirmation, watch the status bar at the bottom of the Central GUI; you should see asaving... message as the production data is saved.

To rename the production, click on its Name field - either once to select allexisting text (white) or twice (black cursor) to modify the existing name. Enter anew name from the console keyboard, and then press Enter.

You can now continue to save regularly into the active production using the frontpanel UPDATE button. Note that this button flashes if you have snapshots whichhave not been saved.

Next Steps

Hopefully, you should now have enough information to start mixing!

Please refer to the Quick Reference guides for a reminder about each control section. You will also find a briefoverview of the console's other SCREEN CONTROL displays in the Appendices.

Compact I/O

Compact I/OThis chapter covers the optional Compact I/O stagebox.

Each 5RU unit provides 32 mic/line in, 32 line out, 8 AES in,8 AES out, 8 GPIO and 1 MADI port. Up to three units maybe connected via the console's RAVENNA ports. Eachstagebox is delivered as a self-contained unit (picturedopposite) and comes with the required RAVENNA networkcable.

If the Compact I/O is specified at the time of order, then theconsole will come pre-configured to accept the deliveredunit(s). As a result, you will find the corresponding sourcesand destinations in your console's Signal List. Please see Assigning an Input Source and The Signal ListDisplay.

If a new Compact I/O stagebox is installed, then the system configuration must be edited using AdminHD.

This chapter deals with:

Frame Installation & Connections

System Configuration (AdminHD)


Compact I/O

Frame Installation & Connections

The Compact I/O is designed to be mobile with two lifting handles mounted on the front of the chassis. All plug-inconnectors are located on the front panel. Therefore, when installing, please leave enough room for the cables.

Temperature and Cooling

The unit is convection cooled and therefore is ideal for installation within noise critical environments. Properoperation can only be guaranteed at an ambient temperature between 10°C and 35°C and a relative humiditybetween 15% and 85% (not condensing).

Warning

Take care that no devices or cables obstruct the flow of air thereby hindering cooling.

Connection to the Console

The Compact I/O should be connected to one of the RAVENNA ports on the console's rear panel, as defined bythe AdminHD configuration. Note that it is important to connect to the correct port number (1, 2 or 3).Connections are made using standard CAT 5/6/7 Gigabit Ethernet, RJ45 connectors, crossed or straight (1:1)cable, up to 100m. A network cable is delivered with the Compact I/O.

RAVENNA links should be directly wired. Providing the correct RAVENNA port is connected (to match theAdminHD configuration), the interface is self-configuring. Thus, once you have connected the ports (e.g. fromConsole to Compact I/O), no further network configuration is necessary.

Warning

To guarantee low latency, reliability and easy setup, do NOT connect any other network equipmentbetween the RAVENNA links.


Compact I/O

System Configuration (AdminHD)If a new Compact I/O stagebox is installed, then the system configuration must be edited using AdminHD.

About AdminHD

AdminHD is the Lawo software application used to configure all mc2 and Nova73 systems. The software isresponsible for generating the config.tcl and gui_config.tcl configuration files, which are read by the controlsystem at boot-up following a cold start. These files define the system components (Core configuration) and theorganisation of signals within the Signal List display (Signal List configuration).

For more in-depth knowledge, please refer to the AdminHD User Manual. The rest of this section covers the steps

required to add a new Compact I/O to a standard mc236 system.

Configuration Checklist

To amend the configuration, please complete each of the following steps:

1. Install the AdminHD software.

2. Connect your AdminHD computer to the mc236 control system.

3. Start the software and download the existing Core and Signal List configuration data.

4. Backup the existing cold start configuration files (config.tcl and gui_config.tcl).

5. Edit the Core configuration - add the new Compact I/O and rename its signals.

6. Edit the Signal List configuration - add the new signals to a Compact I/O directory.

7. Export the Core and Signal List configuration data (as a new config.tcl and gui_config.tcl).

8. Upload the cold start .tcl files from your computer to the mc236 control system.

9. Cold start the console and check the functionality.

Installing the Software

AdminHD can be downloaded from the Lawo website at www.lawo.com (after Login).

Take care to download the correct AdminHD version - the first three digits of the release must match that of your

mc236 system. (You can check the software version of your console from the "Global Options" in the SystemSettings display.)

Run the installer and follow the on-screen instructions accepting the default options provided. By default, files areinstalled in the location: ‘C:\Program Files\Lawo/AdminHD X.XX’. where X.XX is the release version. You caninstall multiple versions of AdminHD on the same computer; there is no need to uninstall the previous version.

Connecting to the mc²36 Control System

1. Connect your computer to the ETHERNET B port on the console's rear panel.

2. Configure the TCP/IP settings on your computer's network interface card.

http://www.lawo.com


Compact I/O

Downloading the Existing Configuration Data

1. Start the programme, by selecting AdminHD for Mixing Consoles from the START menu (Windows) orApplications folder (MAC):

It is important that you choose the correct mode (... for Mixing Consoles and not ... for Nova73),AND the correct software version (the first three digits must match the software running on yourremote system). If not, AdminHD will not be able to connect to the mc²36. Or, the system may notread your configuration data.

AdminHD starts up and opens the last configuration file you were working on.

2. Select File -> New from the main menus, and choose mc2 console. (Do not select mc236 console, asthis will define a default system).

If you have not closed the previous AdminHD session, then you will be asked if you wish to save the file -select No to continue without saving. The new session opens - you will see the entry System in the ‘CoreBrowser’ and confirmation of the system type in the status bar:

Click on from the main toolbar to show the 'Remote log' window at the bottom of the screen -this will indicate the status of all operations as you work with AdminHD.

Click on to show the 'Graphic' view - this will reveal a pictorial view of the System components(see Step 5).


Compact I/O

3. Click on from the main toolbar (Download all data from remote HD) - a pop-up appearsrequesting an IP address for the Remote connection.

4. Enter the IP address of your control system - for example: 192.168.102.36 (the default IP address):

5. Click Connect - AdminHD downloads the Core configuration data from the remote system; the 'RemoteLog' reports on the progress.

After a successful download, the current components appear in the ‘Core Browser' System tree:


Compact I/O

6. Now click on from the main toolbar to show the ‘Signal List Editor’ - a new 'empty' Signal Listappears in the window:

7. Click on (Download GUI signal list config) from the 'Signal List Editor' toolbar to download theSignal List configuration data from the remote system; the 'Remote Log' reports on the progress. After asuccessful download, the 'Signal List Editor' updates:

8. Click on the minimise button (top right) to hide the 'Signal List Editor' for now. We will return to thiswindow later.


Compact I/O

Backing Up the Cold Start Config Files

Before continuing, it is a good idea to make a backup copy of the configuration files stored on the remote system.This will allow you to transfer back the originals should you make a mistake during editing.

1. Select Remote -> Download file from the main menus, and select the Core cold start config(config.tcl) option:

2. You are asked to specify a folder location and name for the file - for example:

3. Click Save - AdminHD downloads the file from the remote system; the 'Remote Log' reports on theprogress.

4. Repeat steps 1 to 3 to backup the GUI cold start config (gui_config.tcl) file.


Compact I/O

Editing the Core Configuration

You are now ready to add the Compact I/O to the Core configuration. At this stage, all changes remain offline (inAdminHD). It is only once you upload a new .tcl file that you start to modify the live system.

1. Use the + and - buttons in the ‘Core Browser’ to reveal the current System components - a standard

mc236 micro-core supports two DSP Modules, an internal RAVENNA link card (RVL) and a single Routermodule.

If you open Module 6 (RVL), you will see four Ports: the top entry (named Compact I/O) defines the internalLocal I/O; the remaining entries define the external RAVENNA ports (1 to 3 RVL).

2. Right-click on the stagebox connection (e.g. Port 1 RVL), and select Define Compact I/O (128channels).

The Compact I/O is added to the System tree, along with its sub components: IO-Card 1 (GPI), IO-Card 2(MIC), etc:


Compact I/O

Renaming Signals

If you wish, you can modify the signal names and labels - for example, if there is more than one Compact I/Oconnected, you could rename the mic signals as "SB1 m01", "SB1 m02" to identify StageBox 1. Note that thesesteps are optional; if you continue to the next section, then the system will apply the default names and labels.

1. Using the + and - buttons in the ‘Core Browser’, open up a card - e.g. IO-Card 2 (MIC) - and select anindividual signal - e.g. Signal In 1.

2. Click on from the main toolbar to show the 'Parameter Box' - here you will see the current Signalname and label:

3. Click in each field to edit the text - you may enter up to 8 characters.

Note that the Signal name can only be edited in AdminHD, and cannot be altered from the console GUI.Therefore, it should be used to provide a "fixed" name relevant to the installation. The Signal label is the labelwhich the system resets to after a cold start. Users can change labels later from the GUI's Signal List display.

4. Select the next signal and repeat as required.

You can use CTRL + C and CTRL + V to copy and paste text between fields.

To name a range of signals with the same suffix, turn on the Extras -> Datasheet -> Comfort TextEdit Mode option; name the first signal and leave your cursor in the "name" field; now press CTRL +SHIFT + PAGE DOWN - AdminHD steps down to the next signal in the system tree andautomatically increments the suffix.


Compact I/O

Editing the Signal List Configuration

Having added a new component to the Core configuration, its signals can now be organised using the 'Signal ListEditor'.

1. Click on the minimised 'Signal List Editor' icon to maximise the window - there should be an asterisk (*)beside the window title to indicate that changes to the Core configuration have been made.

2. Click on the button, from the 'Signal List Editor' toolbar, to refresh the Hardware Tree - your newCompact I/O should appear in this column:

If you closed the 'Signal List Editor', instead of minimising, then open a new 'Signal List Editor'

window, and click on to download the existing Signal List from the remote system and update theHardware Tree.

The 'Signal List Editor' has three columns:

Directories & signals - this column displays the configured Signal List. Signals are organised intodirectories and subdirectories which may be added and renamed as you wish. Use the + and – signs toopen and close each directory and subdirectory to interrogate the individual signals.

Hardware Tree - this column lists all the signals defined in the System configuration. Use the + and –signs to open and close branches of the Hardware Tree. Click on an individual signal, or a card, and thesignal(s) appears in the third column - Selected signals.

Selected signals - this column is used to build a list of signals, which you can add to the selected

subdirectory using the button. Signals in red are already used somewhere within the configuration;those in black are not.

At this stage, the new Compact I/O appears in the Hardware Tree, but its signals have not yet been added tothe Directories & signals.


Compact I/O

To create a new directory structure and add the signals:

1. Click on the Source page tab to configure the input signals.

2. Select an entry in the Directories & signals column - for example, Local I/O - then right-click and selectCreate new directory - the new directory is added below your selection and given a default name.

3. Double-click to edit the name and type up to 16 characters. Note that it is best to keep names as shortas possible for easy operation from the console GUI.

4. Repeat steps 2 and 3 to create and name each directory and subdirectory. Note that the Signal Liststructure supports three levels: directories, subdirectories and signals; you cannot configure additional levels.

Create new directory Rename directory Naming Example

You are now ready to add the signals:

5. First, use the Hardware Tree to build up a list of signals in the Selected signals column. To select allthe signals from a card, click on the card within the Hardware Tree. To select a range, press and hold SHIFTand then select the first and last signal or card. To select non-consecutive signals, press and hold CTRL andthen click on the signals or cards. To remove a signal, select an entry in the Selected signals column andclick on the button.

In our example, we have selected all the mic input signals (from the first MIC card).


Compact I/O

6. Once you are happy with the Selected signals content, choose a directory or subdirectory from the first

column (e.g. Stagebox 1 -> MIC) and click on the button - the Selected signals are added to yoursubdirectory:

7. If you make a mistake, right-click on the signal (in the Directories & signals column) and select Delete.

8. Repeat steps 5 and 6 to add all the new signals to the relevant directory/subdirectory.

9. Repeat all the steps from 1 to 8, but this time choose the Destination page tab to configure the outputsignals:


Compact I/O

Exporting the Cold Start Configuration Files

The next stage is to export the Core and Signal List configuration changes as a new config.tcl andgui_config.tcl.

1. Select File -> Export file -> Core cold start config (config.tcl) from the main menus:

2. Specify a folder location for the file - note that you must NOT rename the file, as it must be named

config.tcl in order to be read by the mc236 control system following a cold start.

3. Click Save - the Core configuration is exported from AdminHD and saved on your computer.

4. From the 'Signal List Editor' follow a similar procedure to export the gui_config.tcl - click on the (Export to cold start config) button on the toolbar.

5. Specify a folder location for the file - do NOT rename the file.

6. Click Save - the Signal List configuration is exported from AdminHD and saved on your computer.


Compact I/O

Uploading the Cold Start Configuration Files

You can now upload the cold start configuration files from your computer to the mc²36 control system.

If you haven't already done so, please make a backup of the old files BEFORE you continue. This willallow you to transfer back the originals should there be a problem.

1. Select Remote -> Upload file -> Core cold start config (config.tcl) from the main menus:

2. Then select the config.tcl file you wish to upload:

3. Click Open.

The file is uploaded to the remote system's cold start data; the 'Remote Log' reports on the progress:

4. Repeat steps 1 to 3, but this time upload the gui_config.tcl.


Compact I/O

Cold Starting and Checking the System

You will need to cold start the mc²36 to see your changes take affect:

1. From AdminHD select Online to remote system to make an online connection, and then selectRemote -> Reset system (cold send):

Or, from the console GUI select the Prepare Coldstart option from the System Settings display, and thenpower off and on.

2. Following a cold start, select the Signal List display on the console GUI - the new Compact I/O(Stagebox 1) and its signals should appear in the Source and Destination Directories:

3. Connect the Compact I/O to the correct RAVENNA port (on the console's rear panel). Once the CompactI/O is connected and powered, the Signal List should update to show that its signals are now available - the !symbol clears.

4. Make a connection to test each signal.
