CSMA1120 Mixer Amp + (12) DCS8T Drop Ceiling Speakers

This bundle gives a restaurant, bar, cafe, office, or retail floor a complete 70V background music and paging system in one order: a JBL CSMA1120 120W mixer amplifier and twelve Rockville DCS8T 8" drop ceiling tile speakers. Each DCS8T comes pre-mounted in a standard 2' x 2' tile, so installing it means lifting out an existing tile, setting the speaker in its place, and running speaker wire back to the amp. No cutting, no back boxes, and no guessing which speakers pair with which amplifier.

The power plan is already worked out. A rear tap selector on each DCS8T sets it to 10W, 5W, 2.5W, or 1.5W on a 70V line, so twelve speakers at 10W add up to the amp's 120W rating. Tap hallways, restrooms, or quieter zones at 5W and you keep the 15 to 20% amplifier headroom recommended for 70V systems. Every speaker wires in parallel on one line, long cable runs hold their signal, and there's no impedance math to work through.

The CSMA1120 packs four inputs and 120W into a fanless 1U chassis that runs silently in a back-office rack, with a rack mounting kit included. Euro-block connectors accept paging mics and line sources, RCA inputs handle a music player, priority muting lowers the music when someone pages, and bass and treble controls let you tune the sound to the room. RJ45 connectors work with JBL CSR-V wall volume controls, and the universal supply accepts 100 to 240V. Behind each metal grill, the DCS8T's 8" paper cone driver offers 91 dB sensitivity and 105° dispersion at a low 3.9" mounting depth, tuned for clear speech and announcements while still sounding good with music and chimes.
