Ideal for commercial and industrial use, this lightweight mixer-amp leverages Crown’s high-efficiency DriveCore Technology and HARMAN’s GreenEdge environmentally-conscious manufacturing so it quickly pays for itself in energy savings. With a sleek industrial look and a clean front panel featuring only volume controls for each channel, it offers you an easy-to-use professional tool with uncompromised performance.
All volume controls on the CSMA 2120 are surrounded by an illuminated ring, making it easy to see and operate in darkened environments. This amplifier can drive 8 ohm and 4 ohm loads and can be used with 70V and 100V distributed audio systems without the need for a separate transformer. In addition to balanced mic/line inputs, unbalanced RCA inputs and speaker connections, this unit includes RJ45 connectors for use with JBL CSR-V in-wall volume controls. This model features a universal power supply which enables the ability to accept AC voltages from 100 to 240 VAC, 50/60Hz.
