Operator’s Guide

Thanks to the sound gating feature, there’s far less need for you to turn
mics up and down during the program. We still recommend, however, turning
down mics that are obviously finding only noise:
•
Mics being moved
by stage handlers
•
Certain wireless receivers that pick up
radio noise
when their mics are
turned OFF – turn up wireless mics only after they’ve been switched ON.
In short, working this mixer is like driving with cruise control – it makes
your job easier, but you still have to drive. Here’s some “safety tips.”
•
When you hear ringing
, reduce gain on the affected mic(s). You’ll know
which mics are causing ringing by watching the mixer’s
GATE
LEDs while
listening for the ringing. Mics gated “off” cannot contribute to ringing at
that moment.
•
The
COMPRESS
LED may glow
green
or perhaps yellow momentarily at
“high points” in the material. That’s good – it indicates you’re providing
maximum usable sound.
•
When accidents happen
– a dropped mic, a cough, or a feedback howl –
the mixer limits these nasty sounds (the
COMPRESS
LED lights
red
).
•
If the
COMPRESS
LED lights
red
for normal material, your mic gain(s) are
set too high! Turn them down until the mixer indicates only a slight,
intermittent compression. You’ll get clearer, more natural sound and
less feedback. If you find yourself frequently needing more volume this
way, slightly increase your power amplifier’s gain setting. You and/or
your system installer may wish to repeat the procedure on Page 18.
