CSMA180 Mixer Amplifier + 10 Black Rock Slim 70V Wall Speakers

Putting background music and paging into a restaurant, bar, cafe, or retail store gets a lot simpler when the amplifier and speakers are already matched. This kit pairs the JBL CSMA180 commercial mixer amplifier with five pairs of black Rockville Rock Slim 70B 5.25" 70V wall speakers, giving you a ten-speaker system for a dining room, sales floor, or lobby in one order. The CSMA180 puts out 80W from a fanless 1U chassis, so it takes a single rack space and runs silently in a back office or AV closet. It connects directly to 70V and 100V distributed lines with no separate transformer, accepts balanced mic/line and unbalanced RCA sources across four inputs, and uses priority muting to drop the music when someone makes an announcement.

Each Rock Slim 70B sits just 1.38" off the wall, and its black ABS cabinet suits darker walls, bars, and accent areas. A 5.25" paper cone woofer and 0.5" Mylar dome tweeter cover 100Hz to 20kHz with clear vocals and full mids. Built-in 8W and 4W taps let you run the dining room louder than the hallway or restroom, and mixing taps keeps the total load comfortably under the amplifier's 80W rating. Installation is about as easy as hanging a picture: the bracket is molded into the cabinet, recessed spring-loaded terminals and a molded wire groove keep cable hidden behind each speaker, and the shielded grille guards against dust. On the amplifier, illuminated volume rings stay readable in a dim room, independent bass and treble controls tune the sound to the space, and RJ45 ports accept JBL CSR-V in-wall volume controls. A rack mounting kit is included.
