Crown 135MA Three Input, 35 Watt Mixer-Amplifier


These amplifiers are used in our REAT systems for talk-back and talk-forward microphones, and support muting via external switch. This is useful to avoid feedback when communicating back and forth between testing and control rooms.

Crown’s 135MA is a high value mixer-amplifier for commercial audio. They provide 8-ohm and constant-voltage outputs (70V). Typical uses are paging, background music, and music-on-hold. The 135MA provides 3 inputs (each with a volume control) and a 35W amplifier output. Other features include priority muting, voice activated muting, phantom power, and bass and treble controls.
