Pan/Bal Panel - AMS Neve Libra Live II Series User Manual

Issue 4 Libra Live Series II User Manual

PAN/BAL Panel

Used to adjust the Panning or Balance of a path.
The PAN/BAL controls are used to route the signal across stereo and suitably surround
designated stems (groups of tracks arranged as surround outputs) or group destinations. They
have no effect on signals routed to mono destinations.
In most instances the FRONT LCR PAN/BAL Logicator is a duplicate of the PAN/BAL Logicator
on the fader strip. The exception is when an output path such as a main output is on the fader
strip. Only the AFU PAN/BAL control will affect the output balance and the fader strip control will
only be available if the output path is also routed to another path, for example if the main output is
routed to a cue.
For surround sound work, the tracks and groups are assigned as mono, stereo or surround sound
destinations using the Pan Designators and Pan Macros in Desk Editor. The pan control is then
destination sensitive and sends the correct pan law to each destination that it is routed to. It can
simultaneously correctly pan across an L-R image, an LCR image and an L, LE, C, RE, R image
for example.
The DIV Logicator is used to control divergence of a stereo signal. Divergence is the surround
equivalent of the stereo width control and affects the size or spread of the source signal in the
surround image.
The FRONT/BACK and REAR LR are for panning across the appropriate axes for surround
destinations.
Each Logicator has an individual ON/OFF key for switching the function in and out as needed for
surround destinations.
The pan/balance function can also be achieved using optional joysticks.
Surround Panning
Surround panning is covered in more detail in the Surround Sound section of this manual.
When a path is routed to surround destinations (track Monitors or Groups that have been setup
as surround destinations Desk Edit) then the panning controls must be enabled according to the
surround format being used. If the correct panning controls are not switched on then the signal
will be routed to the surround destination(s) with unity gain.
Stereo sources are not generally suitable for routing to surround destinations and the panning
controls may not affect the signal in the expected manner. It is advisable to listen to a stereo
source as it is panned across the sound field to determine how it will behave before actually using
it. Alternatively, feed the input into two separate mono paths and pan these independently (this
may not be possible with M/S sources).
To enable panning controls
Press the ON/OFF key associated with the PAN/BAL Logicator.
