CSMA1120 Mixer Amp + (12) DCS6T Drop Ceiling Speakers

This bundle gives a restaurant, bar, cafe, office, or retail space a complete 70V background music and paging system in one order: a JBL CSMA1120 120W mixer amplifier and twelve Rockville DCS6T drop ceiling tile speakers. Swap out twelve 2' x 1' ceiling tiles, run speaker wire back to the amp, and the room gets even, overhead sound without cutting holes or piecing a speaker plan together from scratch.

The power math is already done. Each DCS6T has a rear tap selector with 10W, 5W, 2.5W, and 1.5W settings on 70V, so all twelve speakers at the 10W tap add up to the CSMA1120's full 120W output. Tap the dining room at 10W and hallways or restrooms lower, and the amp stays within its rating. Because it's a 70V system, every speaker wires in parallel on one line, long cable runs don't lose signal, and there's no impedance math to work out.

The CSMA1120 fits four inputs, one output, and 120W into a fanless 1U chassis that runs silently in a back-office rack. Euro-block connectors take paging mics and installed sources, priority muting drops the music when someone pages, and bass and treble controls let you tune the sound to the room. It handles 70V and 100V lines without a separate transformer, accepts 100 to 240V power, and comes with a rack mounting kit. RJ45 connectors also support JBL CSR-V wall volume controllers if staff need to adjust levels from the floor. Each DCS6T uses a 6.5" paper cone driver behind a metal grill with a 105° dispersion pattern and a low 3.7" mounting depth, tuned for clear speech and announcements while still sounding good for music and chimes.
