JBL CSMA2120 8 input - 2 x 120W DriveCore Mixer-Amp, Fanless, 4ohm/ 8ohm/ 70V/ 100V The JBL® CSMA series of Mixer-Amplifiers are 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 – all mixer/amps are highly efficient, fanless and just 1U rack space high. There are both single channel and two channel models with four or eight mixer channels, respectively. The JBL CSMA2120 Commercial Series Mixer/Amplifier is a mixer/amplifier with one output channel and four mixer-channel inputs designed professionally for commercial and industrial use. JBL CSMA2120 is capable of reaching 120W of peak power with 15W per channel. For each channel, the unit's front panel sports is the volume controls, as well as a master volume adjustment bass, treble controls and knob, and a power switch. The volume controls are illuminated making them to be easily recognized and operate in darkened environments.The amplifier is capable of driving both four and eight Ohm loads, and can be also used with 70V and 100V distributed audio systems without the need for a separate transformer. On this JBL CSMA2120's back panel you'll find the speaker connections, the mic/line inputs, unbalanced RCA inputs and phantom power switches, and more. The unit is also equipped with a RJ45 connector for use with JBL CSR-V in-wall volume controls (available separately).This Commercial Series mixer/amplifier, JBL CSMA2120, it widely known for such features priority muting for channel one's input, a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes and voice activating ducking (useful for paging over background music). Also, you may connect to an additional amplifier, with an auxiliary output, though the tone and master volume will have no bearing on the resulting signal. JBL Commercial mixer/amps are manufactured under HARMAN’s GreenEdge™ environmental initiative, conforming to lead-free RoHS standards and utilizing recycled copper, aluminum and steel, an energy-saving powder coat finishing process and other environmentally-conscious manufacturing processes. Their highly efficient DriveCore design reduces power consumption and yields much more efficient operation – up to 80 percent more efficient than previous designs. All models carry a 3-year no-fault transferable warranty.
