JBL CSMA2120 Commercial Series Mixer/Amplifier
Overview
Description
The JBL CSMA2120 Commercial Series Mixer/Amplifier ideal for commercial and industrial use, our new line of lightweight mixer-amps leverage Crown’s high-efficiency DriveCore Technology and HARMAN’s GreenEdge environmentally-conscious manufacturing – so they quickly pay for themselves in energy savings. With a sleek industrial look and a clean front panel featuring only volume controls for each channel, they offer you an easy-to-use professional tool with uncompromised performance.
The amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you'll find euroblock connections for mic/line inputs, as well as unbalanced RCA inputs, speaker connections, dip switches for input routing, and more.
This Commercial Series mixer/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channels one and five, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with two auxiliary outputs, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.
