JBL Professional NCSMA1120-U-USAlifier, 120W Mixer with 4 Inputs and DriveCore Technology, Includes Mounting Kit

Designed for commercial AV and security environments, the JBL Professional CSMA 1120 mixer-amplifier delivers reliable, high-efficiency amplification for paging, background music, and surveillance monitoring. This single-channel 120W mixer/amp uses Crown DriveCore technology to provide clean power in a compact, fanless 1U chassis—reducing heat, noise, and total cost of ownership in control rooms and retail installations. Four flexible inputs accept balanced mic/line sources, unbalanced RCA, and RJ45 connections for in-wall volume control, making it easy to integrate with CCTV, intercoms, and distributed audio networks. The unit supports 8Ω and 4Ω loads as well as 70V/100V distributed systems, letting you drive remote speaker zones without extra transformers. A universal 100–240VAC power supply and illuminated front-panel controls speed deployment and day-to-day operation. Ideal for integrators specifying AV for security, surveillance, monitoring stations, retail, or corporate paging, the CSMA 1120 pairs efficient amplification with simple control.
