    TABLE OF CONTENTS

  • Feature OverviewThe SP / TC / GT features listed beloware common to all Century Series Consoles.

    • SSM/PMI High quality preamplifiers on balanced micro-phone/line inputs and on all balanced outputs for uncompro-mised audio quality and reliability. All IC’s within the audiopath are socket mounted for easy upgrade or service.

    • 48 Volt switchable phantom power on all microphone inputs.

    • Optional transformers available on all microphone inputs andon Group, Left/Right, Mono, and Matrix outputs.

    • Full Bus assignment section on input and group sectionsallow for independent assignment to the Mono Clean Bus inaddition to the Stereo and sub group sections of the console.The Mono Clean Bus allows for any input or return signal tobe assigned to the Mono output without first having to passthrough a group.

    • Dynamic Signal Present and multiple-sample-point peak indi-cator LED’s are used on all input sections of the console aswell as on all primary outputs.

    • Mono/Stereo PFL and AFL system. When a stereo module isused, the signal is monitored in stereo while mono modules aremonitored in mono. Selected outputs may be monitored inmono or as stereo pairs.

    • 8 Auxiliary Mix buses for use as effect and monitor sends.Aux Send circuitry has front panel Pre/Post fader switching.Pre fader signals have internal jumpers to select between a PreEQ or post EQ signal (Standard) source.

    • Standard frame sizes include 24, 32, 40, 44 and 52 position,with a 64 position frame available on special order. Consolesmay be ordered as 4 subgroup (8 Module Positions usedincluding Master Section) or 8 subgroup (12 Module Positionsused including Master Section) versions.

    • Any frame size may be ordered short loaded for later expan-sion.

    • Direct access to Group Mix Bus allows expander mixers tobe easily patched into the console.

    • Full facility return sections includes Gain Control to handle awide range of input levels, High and Low frequency EQ, AuxSends, full Bus assignment section and level, pan, PFL andMute controls.

    • Mute system on input channels is designed to mute both pre-and post-fader signals including those Aux sends used as mon-itors. When muted, PFL circuitry, Peak and Dynamic SignalPresent LED indicators remain fully operational. This is a fea-ture not available on many consoles at any cost.

    • External power supply with optional shared load parallelpower supply for uncompromised reliability.

    • The EQ section includes an EQ IN switch with LED and a80Hz High Pass filter switch.

    • Optional Matrix modules available.

    • Optional Stereo Input modules available.

    • Comprehensive Talkback section allows access to all primaryconsole outputs. Additional access provided to an externallocation such as an on-stage monitor mixer system. Externalsignals can also be assigned into the talkback system includingOscillator and Pink Noise source inputs.

    • Left/Right summing switches to Aux 1-2 and Aux 3-4 allowfor simple setups of overdub mixes by allowing Left/Right sig-nals to be blended with Auxiliary mixes when used in record-ing applications. In contracting applications, this feature allowsthese Aux outputs to act as additional distribution amplifiersfor the Left/Right signals.

    Century Series Console Power SupplyCentury Series Consoles use a separate rack-mountable power supply which provides the specific voltages used by each console.Crest Audio’ Century Series makes use of two different power supplies. The model and frame size of your particular consoledetermines which of the two supplies should be used. SP, TC, and GT consoles use power supplies as follows: Consoles withframe sizes of 24 or 32 modules use supply model XCVA04; consoles with frame sizes of 40, 44, 52, or 64 modules use supplymodel XCVA06.

    Supply IdentificationThe type of power supply can be identified by the model num-ber shown on the back of the chassis and panel label..

    Power RequirementsThe Century Series power supplies have certain electricalrequirements to operate properly. If possible the power supplyshould be connected to a dedicated circuit. Should any otherappliance on the same circuit draw enough current to overloadthe circuit, the breaker or fuse will trip causing loss of powerto the console. Note the maximum current draw specificationsat right. Be sure that the circuit to which you connect the sup-ply can handle the draw. The power switch on the supply front panel is also a circuitbreaker, there is no power fuse. Should the supply ever shutdown, or trip at start up, simply push the switch to the off posi-tion and then on again.

    Ground LinkingSafety Considerations -Each new power supply is shipped with the AC third wireground connected to the console chassis ground. The connec-tion is made at the rear of the power supply unit. This is neces-sary for safety reasons so that exposed metal parts are ground-ed. In the event of a live conductor making contact with theconsole chassis or the power supply chassis then the currentwill flow to ground without a safety hazard arising. Note thatwhen the console is disconnected from the power supply thechassis ground connection to AC third wire ground is brokenand safety protection is lost. For uninterruptible grounding, ina fixed installation for example, make a connection directly tothe console chassis from the safety ground. Disconnect theground link on the rear of the power supply. This disconnectsconsole ground from power supply AC third wire groundwhich would otherwise create a hum-loop.

    Twin Supply OperationWhen twin supplies are in use for automatic back-up, then theground links on both supplies should be fitted. In a situation where the safety ground to the console chassishas been connected and the ground path via the power supplyis causing a hum-loop, then disconnect the ground links onBOTH power supplies.

    Console and Power Supply GroundingConsole chassis ground is electrically connected to audioground, pin 1 of XLR connectors and 1/4" sockets and to theterminal 'CONSOLE GROUND' at the rear of the power sup-ply. The AC third wire connection in the power supply cableconnects the metal chassis of the power supply to safetyground. This connection should never be disturbed. Hazardousvoltages exist inside the power supply which require the caseto be grounded. When rack-mounted, the power supply groundmay transfer to the rack case thru the front fixing screws,though this connection is not reliable. When a console is con-figured within a complete sound system the grounding require-ments may call for the ground link to be disconnected. This ispermissible only when an alternative ground path has beenprovided. If in doubt seek the advice of an experienced electri-cal engineer.

    Power ConnectionsThe connections to and from the power supply vary dependingon your specific configuration. Before setting up the console,always check to make sure the AC voltage marked on thepower supply agrees with the local supply. Always connect theconsole to the power supply before switching on the powersupply. Do not run the power supply if it is not connected tothe console.

    Multiple power supplies can be daisy-chained to provide fail-safe protection in the event of a supply failure. When two ormore supplies are used, both power supplies run all the time. Inthe event of supply failure, the remaining power supply(s) willtake over the entire load.

    NOTE: Although both of the multi-pin connectors on the backof the power supply are labeled “POWER OUT”, it is neces-sary (and acceptable) to link two power supplies together asshown in the diagram below.

    ADDITIONAL NOTE: The multi-conductor cable used forpower supply-to-power supply connection is different than thatused for a conventional power supply-to-console connection,and must be specified when the second power supply isordered.

When the pan is in its center position, signal isfed equally to the odd (left) and even (right) mix bus. Whenused in stereo applications, the channel signal may be locatedanywhere within the stereo image as controlled by the Pan con-trol.

    PFL SwitchSamples the channel’s signal pre-fader and allows for monitor-ing within the master section of the console. This signal is notaffected by the Mute Switch. When depressed, the signal levelcan be seen on the Left/Right meters, and heard via the mixer’sheadphone or local monitor output. When this PFL Switch isdepressed, the channel PEAK LED indicator illuminates at alower intensity. When used as a status indicator of switch posi-tion, the Peak LED indicating circuit remains fully operationalby illuminating at a much higher intensity than its use as a PFLstatus indicator.

    PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of the clipping point. Signal is sampled after the inputpreamplifier stage, after the EQ section, and after the fader.

    This LED also serves as a PFL ON indicator, but at a muchlower intensity than when it is used to indicate clipping.

    SIGNAL PRESENT LEDConstantly displays level activity of the input channel by vary-ing in intensity.

    100mm FaderUsed for control of all outputs of the channel except those Auxoutput sections selected by switch to a pre fader position. (TheInsert Output level is not affected by the fader position.)

    Aux 8 Direct SwitchRemoves the Aux 8 signal from the Aux 8 bus and assigns tothe direct out 1/4" connector on the rear panel.

    PRE/POST SwitchSelects the Aux 5 through 8 signal sources between pre andpost fader positions.

    PAN CONTROLPositions the channel image between the left (odd) and right(even) channel assignment.

    MUTE Switch with LEDMutes the channel and all send functions. This switch does notaffect the PFL switch or the Peak and Signal Present LED indi-cators. The LED illuminates when the channel is muted fromthe local mute switch.

    MONO Bus Assign SwitchAssigns the input signal directly to the Mono Clean bus.

    Bus Assign Switches (L/R, 1-8)Assigns the post Pan Signals to the mix bus in odd/even pairs.Pan controls assignment between these two mix buses withextreme left pan assigning signal exclusively to the odd mixbus and extreme right pan assigning signal exclusively to theeven mix bus. When the pan is in its center position, signal isfed equally to the odd (left) and even (right) mix bus. Whenused in stereo applications, the channel signal may be locatedanywhere within the stereo image as controlled by the Pan con-trol.

    PFL SwitchSamples the channel’s signal pre-fader and allows for monitor-ing within the master section of the console. This signal is notaffected by the Mute Switch. When depressed, the signal levelcan be seen on the Left/Right meters, and heard via the mixer’sheadphone or local monitor output. When this PFL Switch isdepressed, the channel PEAK LED indicator illuminates at alower intensity. When used as a status indicator of switch posi-tion, the Peak LED indicating circuit remains fully operationalby illuminating at a much higher intensity than its use as a PFLstatus indicator.

    PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of the clipping point. Signal is sampled after the inputpreamplifier stage, after the EQ section, and after the fader.

    This LED also serves as a PFL ON indicator, but at a muchlower intensity than when it is used to indicate clipping.

    SIGNAL PRESENT LEDConstantly displays level activity of the input channel by vary-ing in intensity.

    100mm FaderUsed for control of all outputs of the channel except those Auxoutput sections selected by switch to a pre fader position. (TheInsert output level is not affected by the fader position.)

    Scene Mute AssignmentsAssign the input channel to any of the four scene mute groups.Scene mute combines with the module’s local mute button, andactuates the local mute LED.

    Scene Mute Safe SwitchDisables any selected scene mute assignments. An associatedgreen LED indicates the channel is in a safe state.

  • GT Stereo Input ModuleThe GT Stereo Input Module is essentially two GT InputModules fit into one module space. This module is very use-ful for accepting remote feeds, effects inputs and other sig-nals that require stereo handling.

    48V Phantom Power SwitchTurns on 48V Phantom Power for both L and R XLR inputs,required by certain microphones for proper operation.

    LINE SwitchSelects between the Balanced XLR Microphone Input con-nector and the Balanced Line Input 1/4" TRS connector forboth L and R channels.

    XLR PAD SwitchIntroduces a -20 dB drop to the mic input signal for both Land R XLR inputs.

    L GAIN & R GAIN ControlsAdjusts input gain for proper signal level for both L and Rinputs.

    80Hz High Pass SwitchFor both input channels, reduces all low frequency content ata 12db per octave rate referenced to 80Hz (-3db point).

    Polarity Reverse SwitchFor both input channels, inverts the polarity of both themicrophone and line inputs. An internal jumper selectsbetween Left channel only or both Left & Right channels.

    Three-Band Equalizer ControlsThe equalization controls in this module act upon both L andR stereo channels at once. The upper band is a fixed shelvingEQ with one control knob. The middle and low frequency EQbands are set up as sweep EQ’s: the lower knob controls thegain or cut as in the fixed EQ; while the upper knob controlsthe center frequency adjusted by the inner knob. These centerfrequencies are printed on the chassis around the upper knob.

    EQ IN SwitchInserts the EQ section into both L and R input channel sig-nals at once. An associated LED illuminates when the switchis down.

    AUX Level 1•3 / 2•4Adjusts audio level of a mix for use as a monitor or an effectsend. The signal source for this mix may be selected pre orpost fader by an associated switch. The left channel is sent tothe odd Auxes, and the right channel is sent to the evenAuxes.

    POST/PRE SwitchSelects the Aux 1•3 and Aux 2•4 signal sources between postand pre fader positions.

    STEREO SwitchAUX 5-8 Individual Level Controls normally send a summed(L+R) signal to the AUX outputs. When the STEREO switchis depressed, AUX 5 and 6 become a ‘right’ send and ‘left’send respectively. This can be used for a stereo effects send.

  • AUX 5 - 8 Individual Level ControlsAdjusts audio level of a mix for use as a monitor or an effectsend. The signal source for these mixes may be selected pre orpost fader by an associated switch.

    WID(TH) ControlWhen used together with the BAL control, the WID controlprovides a unique way to configure stereo panning. Whenturned all the way counter-clockwise, this control convention-ally assigns the left signal to the left (odd) channel assignment,and the right signal to the right (even) channel assignment.When adjusted to the ‘twelve o’clock’ position, left and rightsignals are panned straight up the middle, effectively summingthem to mono. When this knob is turned all the way clockwise,the left and right signals are ‘flip-flopped’, left being assignedto the right (even) side, and the right side being assigned to theleft (odd) side.

    BAL ControlPositions the entire channel image between the left (odd) andright (even) channel assignment. Together with the WID con-trol, this gives total control of the stereo image.

    Group PFLAllows for Pre Fader Listening of the Group signal.

    Group Peak & Signal LED’sThe red LED indicates that the group signal is within 3dB ofthe clipping point.

    The green LED constantly displays the level of group signalactivity by varying in intensity.

    Group FaderControls all post-fader group signal outputs.

    EFX Return Scene MuteAssignmentsAssign the EFX return signal to any of the four scene mutegroups. Scene mute combines with the effect’s local mute but-ton, and actuates the local mute LED.

    EFX Return Scene Mute Safe SwitchDisables all selected EFX scene mute assignments. An associ-ated green LED indicates the return is in a safe state.

    Rear ConnectionsGroup OutThis connector carries the post-fader outputsignal from the associated group module.

    Group InsertThis jack allows for the insertion of an effector signal processor into the audio path of theassociated group.

    EFX ReturnThese two connectors allow for effect signalsto be brought back into the board. The 1/4"TRS jack accepts a balanced or unbalancedsignal at -10 dB level and delivers the signalto the EFX return section. The female XLRconnector accepts a balanced signal at +4dBlevel and delivers the signal to the EFXreturn section of the group.

    Bus InThis connector accepts a balanced signal at+4dB level, and then sums it with all theother signals assigned to the associatedgroups.

  • Matrix ModuleThe Matrix Module allows the creation of an independent mixusing the Main outputs (and an External Input) as signalsources.

    Matrix AUX IN ControlsControls level of external balanced input signals.

    L & R MAINS ControlsControls level of post fader L & R signals from main section.

    MONO MAINS ControlControls the level of post fader Mono signal from main sec-tion.

    STR PGM IN ControlControls level of Stereo Program being input into the matrix.(These switches do not function on the SP/TC Consoles)

    LEFT/MONO/RIGHT SwitchesSelects which main section signals are introduced into thematrix. (These switches do not function on the SP/TCConsoles)

    GROUPS 1-4 ControlsAdjusts the level of Group signals 1-4 introduced into thematrix.

    GROUPS 5-8 ControlsAdjusts the level of Group signals 5-8 introduced into thematrix.

    MUTE Switch with LEDMutes the output. This switch does not affect the PFL switchor the Peak and Signal Present LED indicators.

    TB ENABLE ControlInjects the talkback signal from the Master section into thematrix.

    PFL SwitchSamples the matrix signal pre-fader and allows for monitoringwithin the master section of the console. This signal is notaffected by the Mute Switch. When depressed, the signal levelcan be seen on the Left/Right meters, and heard via the mixer’sheadphone or local monitor output. When this PFL Switch isdepressed, the PEAK LED illuminates at a lower intensity.When used as a status indicator of switch position, the PeakLED indicating circuit remains fully operational by illuminat-ing at a much higher intensity than its use as a PFL status indi-cator.

    PEAK LED IndicatorIlluminates RED when any of the points monitored come with-in 3db of the clipping point. Signal is sampled after the inputpreamplifier stage and after the fader.

    This LED also serves as a PFL ON indicator, but at a muchlower intensity than when it is used to indicate clipping.

    SIGNAL PRESENT LEDConstantly displays level activity of the matrix by varying inintensity.

    100mm FaderUsed for control of all outputs of the channel. (The Insert out-put level is not affected by the fader position.)

    Rear ConnectionsMatrix OutThis connector delivers a balanced signalfrom the matrix module.

    Matrix InsertThis jack allows for the insertion of an effector signal processor into the audio path of thematrix output.

    Aux In 1This connector accepts a balanced signal at+4dB level, and then sums it with all the othersignals in the matrix output.

    Aux In 2This connector accepts a balanced signal at+4dB level, and then sums it with all the othersignals in the matrix output.
