CSMA1120

The JBL CSMA 1120 combines a four-channel mixer and a 120 W amplifier in one 1U chassis, which is all most single-zone commercial systems need. Connect a music source, a paging microphone and two more feeds, then run the output straight to ceiling, pendant or landscape speakers. The amplifier powers 8 ohm and 4 ohm loads and supports 70V and 100V distributed systems without a separate transformer, so one box covers both wiring approaches. The front panel stays simple: a volume control per channel, output volume, bass and treble, and a power switch, each surrounded by an illuminated ring that stays readable in a dark closet or behind a bar. Rear connections include euro-block mic and line inputs, unbalanced RCA inputs, speaker terminals and an RJ45 port for a JBL CSR-V in-wall volume control over Ethernet. Priority muting and configurable output routing handle paging over music. Crown DriveCore technology keeps the unit fanless, light and up to 80 percent more efficient than earlier designs, and the universal power supply accepts 100 to 240 VAC at 50/60 Hz. Energy Star certified and built to lead-free RoHS standards under HARMAN GreenEdge, with a three-year transferable warranty. A rack mounting kit is included. Suited to restaurants, cafes, retail stores, offices, gyms and houses of worship.
