The Model 135MA Mixer/Amplifier by Crown

The Crown® 135MA is a high value mixer-amplifier for commercial audio. It provides 8-ohm and constant-voltage outputs (70V and 100V). 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.
