Libra Live Features
Easy Emulation Of Familiar Consoles
Libra Live uses a traditional broadcast signal flow with input channels,
groups, main outputs, PFL, AFL and the digital equivalent of console wide
mix busses. The Libra Live is purposely designed to work in a similar way to
analogue consoles. However, where in the past large numbers of faders
and inputs were required, this is no-longer necessary with the Libra Live.
First time users can disregard advanced digital features and operate the
console in a style of working that they are already accustomed to. New
features and alternative working methods may be introduced, as needs
change. The operator is always in control.
Dedicated Controls
With the growing demand for higher quality processing and the permanent
need for more outputs etc, the traditional analogue module does not have
enough space for all the necessary controls. There are two main ways to
solve this problem and AMS Neve offers both solutions.
The Assignable Channel Strip approach: uses a centrally located panel
with all the channel controls on dedicated knobs and switches called to
any fader with a single button press. The benefit of dedicated controls is
that there is no need to check the function of a control before using it; a
great speed advantage when the pressure is on.
The Channel Strip approach: keeps all the controls associated with the
channel in line with the fader. A single button press brings the EQ to the
surface, or the auxiliary sends. Many operators find this approach intuitive
as it more closely resembles an analogue console and allows easy
simultaneous adjustment on multiple channels.
It is also possible to fit a Libra Live Series II with a combination of strips
and an assignable centre section.
Configuration Library
Libra Live offers a user-definable library of configurations for those rare
occasions when a user chooses to change the configuration of the
console. The configurations, which may be modified, allow stereo channels
where you need them; any mix of mono and stereo auxiliaries; and
processing in the order and type that works best for your audio.

Visual Displays and Hard Controls
When mixing audio for TV there are enough monitors to keep an eye on
without having a console cluttered with additional screens. On the Libra
Live, the user has full control of the audio without needing to use screens.
Once the show has been loaded, neither of the two screens in the Libra
Live are essential for operation. The screens are there simply to offer a
visual display of the EQ and an overview of the console's routing.
Total Visibility
Routing on Libra Live Series II couldn't be easier:
Forward Interrogation (Routing)
Hold down a source button and all the destinations on the routing panel to
which it is routed will illuminate, with no paging required.
Reverse Interrogation (Routing)
Hold down a destination button and all the sources that are routed to that
destination will illuminate. No paging is required if there are less than 96
input channels. (Libra Live is capable of handling up to 192 input
channels).
To change the routing, hold down a source button and touch the required
output buttons.
Alternatively (and more conveniently when setting up a group or an
auxiliary output), hold down the output button and select the required
inputs.

The EQ and Dynamics curves can be displayedgraphically, and the display follows path selection
on the console surface.
Features continued
Mono Or Stereo Inputs In Any Order
Any fader may be made mono or stereo without restriction on quantity or
position. Inputs may also be re-arranged on the surface to suit momentary
needs without interrupting the audio. All the channel settings, including the
scribble name, are instantaneously and noiselessly transferred from one
channel strip to another. Groups and outputs can be mono, stereo,
analogue or digital and as far or near to hand as the style of operation
requires.
Clearly Visible Control Settings
AMS Neve's patented Logicator
controls have unique illuminated
position indicators in the top of the
knob. This feature makes it easy to
see the position of the control from
any angle, regardless of whether
movements are made manually, or
by one of the console's automation
systems.
Whenever a control is touched a precise digital value is displayed in a
nearby window. Functions with interactive controls, such as EQ and
dynamics, also have screen based, high resolution graphics to help
visualise the overall effect of the whole group of controls. Other indicators
only become visible when relevant, making it easy to read the console
status.
Flexible Mix Minus
In addition to regular aux sends, Libra Live Series II includes a dedicated
mix-minus matrix for IFBs. This most flexible of systems combines simple,
clear operation with full metering, monitoring, talkback and level control.
Unlike conventional channel based n-1 systems, outputs are not tied to
specific inputs, so there is no need to re-patch every time a different clean
feed is needed. 'On the fly' changes may be made at will, with sources
added to or removed from an output at the touch of a button. For off-air
conferencing, sources can also be switched pre-fader. Up to 96
independent mix-minus feed outputs may be created.
Tone and talkback may be switched into the mix-minus outputs individually
or globally.

Built-in I/O Router
Up to 672 analogue or digital inputs can be connected to Libra Live Series
II, from which over 200 can be used simultaneously. Selection is via an
integral router screen, or simply by selecting the input on the required
channel. All analogue and digital input and output interface racks connect
to the console via MADI, allowing easy interfacing to additional external
routers, or direct 3-cable connections to digital multitrack recorders.
Modular I/O System (MIOS96)
Libra Live uses a compact high resolution I/O system that is ideal for
remote mounting.
For more information on MIOS96 visit www.ams-neve.com or contact
your local office.
Flash RAM
The software which operates the console is stored in Flash RAM - a
non-volatile memory which retains its contents when power is removed.
This makes the system faster to start, with no dependency on the
mechanical stability of a hard disk. Flash RAM increases reliability
particularly in mobile applications, while retaining the ability to upgrade
software as new features become available.
SRAM Tracking
The console configuration is written into battery-backed Static RAM
(SRAM). This further improves the start speed, removes reliance on the
hard disk and allows the console to track every control change made, so
that it will restart in exactly the same state as it was when the power was
removed.
Comprehensive GPI
In addition to the usual fader start, mic-live and on-air logic and
signalling, Series II comes with a user configurable General Purpose
Interface (GPI) that supports functions such as snapshot recall, remote
monitor selection, lazy talkback, third party talkback/intercom support, etc.

“As the Libra Live can be set-up as being any desk you want it to be, any external operator can workwith it almost instantly. Since we had almost exclusively stereo sources in this particular event it wasvery useful that we could set-up the desk surface to our exact needs with both operators having theirchannels right in front of them. On a regular console you’d have to route your sources according tothe desk layout which could also limit operator convenience.”
Frank Mosch, Outside Broadcast

Surround Sound
Multi-format surround sound is built into
Libra Live as standard, providing basic
facilities for occasional surround sound
projects.
There is also a full surround monitoring
option available for Libra Live that
provides multiple surround sound
outputs, more convenient monitoring,
Dolby E� support and joystick panning.
This option can also be retrofitted if the
need for surround sound arises in the
future.
Snapshot Automation
Libra Live Series II provides a simple
method of capturing the position of
every control on the console and
restoring the position at any time with as
few as just 3 button presses.
More importantly, the snapshot system also allows full operator control
over which parts of the console are to be reset - from protecting the
presenter's channel, or recalling just his EQ, to resetting half the console
for the second band of the evening.
Dynamic Automation
In the event that greater flexibility is required, the Libra Live also has the
ability to run dynamic automation. The movement of every control on the
console can be recorded and replayed against timecode. Mixes can be
edited and updated, stored and transferred to other consoles in the AMS
Neve family of post-production consoles. Libra Live Series II has a 6 port
synchronising tape transport controller built in. This allows an audio
machine to be locked to a video transport for simple post-production or
audio recovery work. Encore automation on Libra Live is exactly the same
as that used on the world’s definitive mixing console, the DFC, which mixes
the world’s biggest blockbuster movies.
Offline Encore
For those occasions when
configuration is required
off-line, all the essential
information about the
console - the number of
faders, processing and
quantities of I/O can be
transferred in one file to a
stand-alone PC running
Encore automation. This
PC can then be used to
pre-configure the console off-line, including options to define the numbers
of channels and mix-busses; select channel inputs; and setting up routing.
Libra Live's unique Desk Editor enables absolute control over the console
configuration.

PFL on Overpress
Libra Live uses this standard broadcast feature, omitted on many other
digital "broadcast" consoles.
Intelligent Layers
Layers allow the Libra Live to handle more inputs than there are faders. For
most broadcast applications, one layer at a time is enough. However, up
to 4 layers are available, for example:
� Slave inputs, such as audience mics controlled from a master fader onthe surface.
� Back-up inputs.
� The band's microphones - brought to the surface for their number andthen taken off again.
� Multitrack returns.
� Spillover on a once-a-year special e.g. election night.
Whatever the application for layers, it's important that access is
straightforward and that signal paths can be moved between layers easily.
Libra Live allows layers to be selected on individual faders or globally
across the console. The top row of Logicators can also be used as small
faders for a second layer if required and there are fader lock and Logicator
lock buttons to prevent individual paths such as presenters' mics from
being accidentally removed.
Two versions of the in-line bargraph meter are available, one with full
height metering and one with metering for both the small and large fader.
Both meter types can be switched to display dynamics on the right hand
side.
Meter Bridge Options
Libra Live has an incredibly large
headroom within its DSP, making it
impossible to overload the processor.
The only places signal level is critical
is at the physical I/O ports - and this
is where Libra Live has its metering
points.
The fader strips are equipped with
large, bright input signal presence
and overload indicators as standard
and a small bargraph indicator that
can be switched between dynamics
gain reduction or input level. These
alone are often sufficient for input
level monitoring.
There are also two optional in-line
meter packages as illustrated.
Two pairs of analogue output
meters are provided which can be
either VU or PPM.
Alternatively, the whole meter
bridge may be customised with
the user’s choice of instruments
and fittings.

Audio Follow Video(V2.8 software)
Libra Live's AFV system offers more than just remote channel on/off
switching. Each fader's in and out fade times are programmable, as is the
minimum level to which the channel will fade. Operators can choose
whether the faders move to reflect the tally control, or stay still to enable
trimming.
Dual Control Option
In applications where there is more than one operator it can be useful to
have a second assignable central channel section. Libra Live allows the
console to be split between two operators at any fader point. Each
operator may have their own independent set of channels, or channels
may be duplicated in each section allowing parallel access to controls.
Resiliency
In the rare event of a failure Libra Live exploits a range of techniques to
keep audio on air:
� Redundant PSUs in every rack.
� Bootable from Flash RAM or disk.
� PC and console surface can be switched off without affecting audio.
� The processor will re-allocate around faulty processor boards using auser defined path priority system.
� Ultra stable audio processing software and detailed diagnostics.
� Hot pluggable I/O.
� User warnings of common external failures such as sync loss orremoval of a remote I/O rack.
Networking & Resource Sharing
Broadcasters with two, or more Libra Live equipped studios will benefit
from networking and resource sharing advantages. By networking the
consoles via Encore automation, desk set-ups may simply be shared
between studios.

ISSUE 6 9
MADI - the AES standard forMultichannel Audio Digital Interfacing
Libra Live Series II makes use of MADI, the AES standard for MultichannelAudio Digital Interfacing. Using MADI provides several significant benefits,including:
Ease of Connection
Up to 56 channels of digital audio data are transmitted on one cable. AMSNeve's MIOS system uses a MADI connection that also carries sync and micamp control.
Cost Benefits
Use of MADI means that expensive analogue converters are not required foruse with multitracks. AMS Neve's low cost TDIF- MADI interface rack enablessimple MADI interfacing with 48 tracks of low cost Tascam modular digitalmultitracks.
Long cable runs/signal quality
Using MADI, long cable runs are possible without degrading audio quality - upto 2km if using fibre optic cable.
Redundancy
Parallel redundant MADI links may be made between the console and a remoteMIOS I/O rack.
Signal Routing
Use of MADI provides the flexibility of picking off MADI channels for cable freeinternal routing. Wider connectivity is also possible via AMS Neve's DNA(Digital Networked Audio) or third party routers which also make use of MADI.
Typical Libra Live Series II System
The flexibility of the Libra Live Series II means that the console's scalable
architecture is more than capable of meeting the needs of medium to large
sized studios as well as outside broadcast vehicles.
With the Libra Live you can be assured that you will always benefit from the
latest technology as the console is fully equipped to be upgraded at any
point with all the latest technological advances. In addition, if your
operational requirements change, the console can be upgraded to meet
your needs.
Unlike conventional analogue consoles, the Libra Live Series II can
accommodate large numbers of inputs while retaining a small footprint.
