3.3 Setting Gain Structure

The primary goal when establishing the gain settings of the MC mixers is to have each channel
operating at the maximum gain without clipping, while leaving adequate headroom on the
volume control knob. Setting the gain structure involves two interactive adjustments: the
channel's front panel volume knob and the channel's input gain/trim control.
The channel input gain/ trim control directly control the microphone preamplifier available at
each channel.
The channel volume control on the front panel controls
how much of the gain is routed to the main output stage.
The front panel controls should optimally operate between
"10 o'clock" and "3 o'clock" when gain structure is
correct.
The master output control on the front panel controls the mixer's final amplifier stage to
themaster output. This control should optimally operate between "10 o'clock" and "3
o'clock" when gain structure is correct.
With all channels operating, the main output meter should show a signal output range between
0 and +6. Adjust the main output control accordingly. If the output occasionally peaks in the
range of +6-+12, activate the compressor/limiter.

3.4 Gain Structure Procedure

1. Adjust each channel's input volume.
a. Verify an audio source is driving the channel being adjusted. Turn the front panel
volume knob for that channel up until the yellow (+3 to +6) range of the LED
bargraph lights. The channel adjustment is correct if the front panel volume knob is
between "10 o'clock" and "3 o'clock" when the yellow range is reached. Make
small adjustments using the front panel volume knob.
b. If the front panel volume knob is not between "10 o'clock" and "3 o'clock", adjust
the gain/trim control.
- If the front panel volume knob was set lower than "10 o'clock", set the front
- If the front panel volume knob was set higher than "3 o'clock", set the front
2. Toggle the amplifiers to the audio levels desired and use the mixer's front panel volume
knobs to make final adjustment to levels.
