CSMA240 Mixer Amplifier + 4 8124 Ceiling Speakers + 2 Black CSR-V Controllers

This JBL package covers a small commercial space with background music, paging, and wall volume control in one order: a CSMA240 mixer amplifier, four 8124 4" ceiling speakers, and two CSR-V in-wall volume controllers. It suits cafes, boutiques, salons, waiting rooms, and small offices that want clear overhead sound without piecing a system together part by part.

The CSMA240 puts out 40W per channel across two output channels and connects directly to 70V or 100V distributed speaker lines through its built-in output transformer, so there is no separate transformer to buy or wire. Run two speakers per channel and you have two zones, each with its own bass and treble. Eight mixer inputs take mic and line sources on euroblock connectors plus unbalanced RCA, and 27V phantom power runs condenser paging mics. Voice activated ducking on channels 1 and 5 lowers the music when someone speaks, and priority muting silences the other inputs for announcements. Sleep mode powers the amp down after about 30 minutes without signal.

Each 8124 pairs a 4" full-range driver with 93 dB sensitivity and 130° conical coverage across 60 Hz to 18 kHz, with 6W, 3W, 1.5W, and 0.75W (70V only) taps to set the right level for each room. The open-back design and dog-ear blind mounts let the speakers go into a ceiling without a backcan, and each one ships with its sculpted grille. The two CSR-V controllers connect to the amp's RJ45 ports over standard Cat 5 cable on runs up to 1,000 ft, so staff can adjust the level from the wall instead of walking back to the equipment rack.
