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

0.0dBFS (digital full scale). You can move several faders 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 MUTE MACHINE 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 ALL key 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.
