mono channel. Set the GAIN control by watching the LE
graph meters—above the MAIN MIX level control in the
Master section of the mixer—while the signal source for that
channel is active (whether it be a microphone or an instrum
connected to the LINE IN of the channel). The ideal level is
between 0dB and +6dB on the bar graph meters.
If the CLIP LED on the channel lights up consistently, the
GAIN control is set too high. It is acceptable for the CLIP
LED to flash periodically especially with loud instruments li
drums or during peak sound levels during loud portions of a
performance.

chosen from the prime frequencies for most
musical applications, and allows up to 15
decibels of boost (increase) or cut (decrease) of
the signal in the tone range for which it controls.
