you can listen to them through your headphone.
l For”+4” line level audio signals, slide the +4/-10
switch to +4.
l For “-10” sources, slide the +4/-10 switch to -10.
l For microphone sources, the gain control adjust-
ment will depend on what kind of the microphone
you use, normally turn the gain clockwise around
2~3 o’clock. But please ask the singer to per-
form outloud, don’t whisper, if they do not sing at
a normal level while you are doing the sound check,
you might drive the mixer to overload or produce
feedback, because you set the gain too high dur-
ing the initial set up.
l Repeat this procedure on all other channels. When
more channels are added to the mixer, the meters
LED may move up to the red section. Adjust the
overall level using the master faders if necessary.
INITIAL SETUP
This procedure is very important. Even if you don’t
like to read manuals, please read this section. Af-
ter you have connected the system, you can begin
the initial set up for every input channel. The match-
ing of every input gain to the signal source is crucial.
Every detail affects the final output of the mixer.
Basically, the input sensitivity adjustment, chan-
nel fader, and output fader are the main factors.
You should try to set only as much microphone
gain as required to achieve a good balance between
signals. If the input gain is set too low, you will not
get enough gain on the faders to push the signal up
to an adequate level. If the input gain is set too
high, the channel fader will need to be pulled down
in compensation, but leave the greater risk of feed-
back because a small fader movements will have a
very significant effect on output level. Certainly, the
limited fader travel path will not be successful in
the mixing procedure. Please use the following set
up procedure. Don’t turn the output up until they
clip and then backing off.
FOLLOW THE PROCEDURE FOR EACH
CHANNEL IN USE
l Set all faders and gain controls all the way off.
l Phantom powered microphone should be con-
nected before the +48V is switched on.
l Set power amplifier levels to 70%.
l Set the CTRL RM Level and Headphone level to
about 50%.
l If you want to hear what you’re doing later, plug
your headphone into the phone output socket,
or hook up your control room amplifier system
to the Control Room outputs.
l Set EQ control at center position.
l Set PAN and BALANCE knobs at center position.
l You need a headphone to continue.
l Apply a typical performance level signal, moni-
toring the level on the LED meter.
l Adjust the input gain until the meter shows in
the amber section, with occasional peaks to the
first red LED at maximum source level. This al-
lows enough headroom to accommodate peaks
and the maximum level for normal operation;
