Set the input level
to each channel just below the peak - you
may have an overload indicator light on your
channels to show this.
Turn the master levels
up half to three quarters - this may seem
high, but it has the effect of increasing
the headroom or available power on hand.
Raise the channel volume
controls to the desired level (setting the
channel volumes high and the master volume
low can cause distortion and unwanted feedback).
Setting E.Q. levels
(such as Bass) too high can draw more power
and could cause speaker distortion.
It's
important to get to know your system's limitations
- trying to get big bass sounds from a system
not designed to do it is asking for trouble!
