For paging, an auto-mute function that provides voice-activated priority muting is included. Rear-panel switches let you select which inputs activate and respond to muting. Other features include external switch-closure mute activation, channel and master volume controls, treble and bass controls, processor insert jacks, and an output level meter. Protection circuitry for overheating and short-circuiting ensure extended operation.
