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 .
Do not operate the system with the input peaking
(red overload light on or flashing) and the master
volume turned down .
Red lights flashing 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 amplifier stage of the mixer . At this point
it will sound dirty and “fizzy” 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 .
