36. CHANNEL GAIN CONTROL - This adjustment is used to adjust the audio source signal input
gain for a channel. Never use the gain control to adjust a channels output volume. Setting the gain
level properly will ensure a clean output signal. An improper gain level adjustment will send a distorted
signal throughout the entire audio line which may damage speakers and amplifiers. To properly set a
channels gain level control:
1. Be sure the MASTER VOLUME CONTROL (14) is set to level 8.
2. Set the CHANNEL FADER (31) to level 8.
3. Begin playback on an audio source connected to the channel you are adjusting.
4. Use the Gain Control to adjust an average output volume of +4 dB.
5. Repeat this step for all channels.
