CSMA240 2x40W Amplifier + (8) Black 5.25" Slim Wall Speakers

The JBL CSMA240 8-input mixer-amplifier and eight Rockville Rock Slim 70B black wall speakers give restaurants, bars, and cafes a full room of low-profile sound without a single speaker box standing out from the wall. The amplifier mixes up to 8 sources down to 2 outputs at 40W per channel, and a Hi-Z switch brings in the built-in transformer for direct 70V or 100V speaker wiring, so no separate step-up transformer is needed. Voice-activated ducking and priority muting on channels 1 and 5 let a page cut through background music automatically, and a sleep mode powers the unit down after about 30 minutes of silence.

Each Rock Slim speaker has its mounting bracket molded directly into the cabinet, so hanging one takes the same effort as hanging a picture frame, and recessed spring-loaded terminals with a molded wire groove hide the cabling completely. A 5.25" paper cone woofer paired with a 0.5" mylar dome tweeter keeps sound balanced between bass and highs, and a rear switch selects 4W or 8W of 70V power per speaker, so quieter zones and louder ones can share the same amplifier. With eight speakers included, this bundle is sized to wire a full dining room or retail floor in a single order, with every speaker sharing the same low-profile look.
