Operating tips
To avoid overloading the pre amp inputs,
always operate the master volume at a high
level and control the volume from the input
volume. The ideal situation is to have all the
components of the audio chain operating at
the same operational range. Do not run the
system with the mixer “peaking in the red”
while the box is turned down.
Also do not operate the system with the input
peaking (red overload light on or ashing) and
the master volume turned down.
Red lights ashing on a mixer indicate
distortion. If you have a mixer with the facility
to show you the input level on a meter, for
example then you push a CUE/PFL button,
set the input level to below the level of the
red end of the LED ramp. If you run the row
of red lights to the end of the ramp you will
cause distortion at the very start of the pre
amplier stage of the mixer. At this point
it will sound dirty and “zzy” regardless of
how good the rest of your sound system is.
The rest of the system will be reproducing a
distorted sound. If you need more volume,
turn down the input signal so it is out of the
red and turn up the output of the mixer.
