Product Description

The JBL CSMA1120-U is a four-input, single-output commercial mixer amplifier with a fanless 1U rack design for installed sound systems. It accepts balanced mic/line and [Used]nbalanced RCA sources, then feeds 4- or 8-ohm speakers or 70V/100V distributed systems without a separate transformer. Front-panel channel and master controls, plus bass and treble adjustment, make it practical to tune paging, background music, or program audio at the rack. Illuminated control rings remain visible in dim equipment rooms and venues. Priority muting, configurable output routing, and RJ45 support for JBL CSR-V wall controls suit offices, retail spaces, schools, and other commercial installations. A rack mounting kit is included.
