CM Series power amplifiers have a standard AC switch on the front panel.

The CM Series is designed to operate under extreme conditions. The
front-panel design features a duct that allows air to be drawn in by the fan,
circulated through the removable filter (for cleaning) and finally dispersing
out the sides of the unit. The openings on the front and sides of the unit
should never be blocked. It is recommended that the removable filter be
cleaned with compressed air.

Upon powering up the unit, the Protect LEDs illuminate momentarily and
then turn off one channel at a time and then remain off. During normal
operation, an over-current condition can occur if the amplifier is being
overdriven to the point where clipping is continuous or from a short circuit
in the speaker output. The Protect LED will illuminate red when one of
these conditions occurs.
The internal temperature of CM
Series amplifiers is 65º celsius. Should
the unit exceed this temperature, the amplifier will go into thermal protect
mode (generally, this would only occur if the internal fan fails). If the
amplifier has a thermal fault condition‚ all LEDs will illuminate. When the
amplifier cools down, the unit will restart automatically.
