Gain Controls
Use these controls to adjust the signal level of each input channel. First select the fader knob, then
adjust the level with the mouse, arrow keys, or specify a level in the value box. For complete
instructions on their operation, see the Faders section on page 31. The adjustment range is from
+30dB to –30dB, and the default setting is 0dB, or unity gain.
Note: The input gain controls adjust the level of the signal after it has already been
digitally converted within the System Processor. Signal levels exceeding the
input threshold of the System Processor must be adjusted externally.

groups, see the Linking section on page 25.
