JBL NCSMA1120-U-US Commercial Series Mixer/Amplifier
Product Overview
The JBL CSMA 1120 (NCSMA1120) is a commercial series mixer/amplifier that combines a multi-input mixer with an integrated amplifier in one unit, for distributed background-music and paging systems. It supports 70V/100V and low-impedance loudspeaker loads.
Product Description
The CSMA 1120 mixes several mic and line sources and amplifies the result to one zone, simplifying small commercial systems by removing the need for a separate mixer and amplifier. Selectable distributed-line or low-impedance output supports a range of loudspeaker layouts, and it integrates with JBL CSR wall controls. For loudspeakers to pair with it, browse the JBL Professional Installed Audio collection.
