AC Power Switch/Circuit Breaker

The CPX Series amplifiers have a combination AC switch/circuit breaker
on the front panel. If the switch shuts off during normal use, push it
back to the ON position once. If it will not stay on, the amplifier needs
servicing.

Input Attenuators

Whenever possible, set the attenuators fully clockwise to maintain
optimum system headroom. The input attenuator controls located at the
front panel, (one for channel A, one for channel B), adjust gain for
their respective amplifier channels in all modes. See the specifications
at the end of this manual for standard voltage gain and input sensitivity
information.

The power only breaks
one side of the AC mains.
Hazardous energy may be
present in the enclosure
when the power switch is in
the OFF position.
When operating in the bridged
mode, both attenuators must
be in the same position so the
speaker load will be equally
shared between the channels.
See the section on Bridged
Mono operation for more
information and precautions.
