CSMA280 Amplifier + (2) CSR-V Wall Controls

The CSMA280 mixer amplifier gives restaurants, retail stores, offices, and other commercial spaces a complete background music and paging system in one unit, and this bundle adds two black CSR-V wall volume controls so staff can adjust levels from the floor instead of the equipment closet. Eight mic/line inputs feed two 80W output channels, and the built-in transformer runs 70V or 100V distributed speaker lines directly, or 4 and 8 ohm loads, with no separate transformer. One amp can cover a dining room and a patio, or a sales floor and a back office, as two independently adjustable zones.

Each CSR-V connects to one of the amplifier's two RJ45 remote volume ports over standard Cat 5 cable with runs up to 1000 ft, so both zones get wall-mounted volume control out of the box. Voice activated ducking on channels 1 and 5 lowers the music automatically when someone speaks into a paging mic, and priority muting cuts every other channel for announcements, even waking the amp from sleep mode. Euroblock and RCA inputs accept mics, music players, and streaming sources, 27V phantom power runs condenser mics, and independent bass and treble controls let you tune each zone to its room. An auxiliary output feeds additional amplifiers when the system grows, and sleep mode powers the unit down after about 30 minutes without signal to cut idle energy use.
