CSM14 [Open Box]

The JBL CSM14 is a 4-input, 1-output commercial mixer built for background music, paging, and security audio in schools, hospitals, restaurants, and fitness facilities. It combines four sources, including euro-block mic and line inputs plus unbalanced RCA inputs for consumer devices, into a single output, with independent bass and treble controls for shaping the overall sound. The fanless, one-rack-unit design keeps the unit silent in an equipment closet or behind a front desk.

A universal power supply accepts AC voltages from 100 to 240 volts at 50 or 60 Hz, letting the mixer work across different electrical setups without extra hardware. RJ45 connectors support an optional JBL CSR-V wall volume control, so staff can adjust levels from the floor instead of the rack, and phantom power is available for microphone inputs that need it. Priority muting and VOX ducking let a page or announcement cut through background music automatically, which matters in facilities where overhead announcements need to be heard clearly. Built with HARMAN’s GreenEdge environmental standards and RoHS-compliant materials, the CSM14 is sized and priced to sit at the front end of a larger paging or background music system.
