JBL Professional NCSMA240-U-US Audio Mixer

Deliver consistent, professional audio for commercial, retail, education and security applications with the JBL Professional CSMA240 mixer-amplifier. This compact 1U, fanless pro audio mixer combines Crown DriveCore efficiency with flexible connectivity so integrators can power paging, background music and monitoring from a single rack-mounted unit. With eight inputs and two outputs capable of 60 or 120 watts, the CSMA240 supports both low-impedance (4Ω/8Ω) speakers and 70V/100V distributed audio systems without external transformers—ideal for large facilities, surveillance command centers and multi-zone installations. The clean front panel gives technicians easy access to individual channel volumes, master level, and adjustable bass/treble, while illuminated control rings improve usability in dim monitoring rooms. Energy Star qualified and built under HARMAN’s GreenEdge initiative, it lowers operational costs and complies with commercial environmental standards. Use the JBL CSMA240 in security paging, public-address, or AV monitoring setups where dependable, easy-to-manage audio is required.
