2.3 INITIAL SET UP
This procedure is very important, even if you don
t
like to read manual,
please read this section. After you connected up the system, you are ready
to set the initial set up for every input channel, the matching of every input
trim to the signal source is crucial, every detail will affect the final output of
the mixer. Basically, the input sensitivity adjustment, channel fader, groups
and output fader is the main factors. You should try to set only as much
microphone trim as required to achieve good balance between signals. If the
input trim 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 trim is set too high, the
channel fader will need to be pulled down in compensation, but leave the
greater risk of feedback because a small fader movements will have a very
significant effect on output level. Certainly, the limited fader travel path will
not successful in the mixing procedure. Please use the following set up
procedure, don
t
use the old way: turning the output up until they clip and
then backing off.
