JBL NCSMA1120-U 4-Input, 1x120W Drivecor Mixer/Amplifier, 70V/100V

The JBL® CSMA series 1120 mixer/amplifier is a professional tool with a sleek, industrial look that is designed and built for commercial sound applications. Utilizing Crown’s DriveCore technology enables significantly reduced size and weight. It’s highly efficient, fanless and just 1U rack space high. The CSMA 1120 mixer/amp offers unmatched ease of use, with a clean front panel featuring only volume controls for each of its four channels, master volume adjustment, adjustable bass and treble controls and a power switch. All the volume controls are surrounded by an illuminated ring, making them easy to see and operate in darkened environments. The CSMA 1120’s 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, all units include RJ45 connectors for use with JBL CSR-V in-wall volume controls. Also features a universal power supply which enables the ability to accept AC voltages from 100 to 240 VAC, 50/60Hz.
