SETTING THE MICROPHONE GAIN
The gain controls allow you to set your input signals to
an optimum level: not so hot that the mixer is overload-
ed, and not so low that the signal is lost in noise. For
a signal entering the XLR mic inputs, the adjustment
range is from 0 to 60 dB. Use the following procedure for
setting the gain just right:
1. Press the solo switch at the bottom
of the channel your microphone is
connected to. The flashing rude solo
light is a reminder that what you are
listening to in the control room and
headphones, and shown on the main
right meter is the soloed channel.
2. Make sure the solo mode switch is in
the PFL (pre-fader listen) position
(out). This is just below the rude solo
light and solo level knob.
3. Sing/talk/shout/scream into the micro-
phone at typical loudness levels.
4. Adjust the channel gain control until
the right main meter level is hovering
around the 0 dB mark (labeled "level
set").
5. Now that the gain is set correctly,
disengage the solo switch.
6. During a performance, if you notice
that the OL (overload) LED comes on
next to the channel fader, carefully
decrease the gain until OL no longer
comes on.
