The 960L Surround Panning Rules
The 960L does not produce a phantom center in surround
modes, and no signal will appear in both the left and right
output channels, no matter where you set the joystick. In
other words, panning across the front is either between Left
and Center or between Right and Center. For example, an
output signal panned to position 1 in Figure 4-19 would
appear in the left and center front channels and the left and
right surrounds, but would not appear in the right front.
The 960L has true constant-power panning. As you pan a
sound from one channel to the next, the sum of those
channels’output powers will not change.
Setting Levels
In Input and Output Edit modes, moving any fader changes
its associated signal level. The maximum level indication is
0.0 dBFS (digital full scale). You can move sev er al f aders at
once.The channel assignments are grouped to facilitate this.
With outputs set to “0dB,”a +4dBu analog input will produce
a -20dBFS signal. This provides 20dB of “headroom.”
Optimum S/N is achieved when input levels are kept as
close to digital full scale as practical.
Avoiding Overload
If all eight of the “Overload” LEDs on the LARC2’s meter
bridge light, the DSP is overloading internally. (Certain
combinations of parameter settings can cause this.)
Reducing input levels may or may not cure the problems.
If your edits create feedback, press the MUTEMACHINE
key on the LARC2’s Numeric Keypad to mute the output of
the current DSP while you solve the problem.
If you’re not sure which machine is causing the problem,
press the MUTE ALLkey on the Numeric Keypad.
Assigning New Parameters to Faders or the Joystick
Except in Edit modes, the parameter assignments of the
faders and joystick make up what we call a virtual page, or
V-Page. This is simply a convenient grouping of
parameters to simplify operation, but you can group them
any way you find convenient.
There are two ways to assign new parameters to the LARC2
controls:
• Assigning parameters from the V-Page
• Assigning parameters as an Edit option.
