JBL CSMA 2120 8-input commercial mixer/amplifier — 120W x 2 at 70V

If you need a powerful, versatile sound system for a growing business, the JBL CSMA 2120 has you covered. Eight input channels give you plenty of options for background music, with two priority channels for microphone connections so paging and announcements can be heard loud and clear. With two channels of 120 watts each, capable of driving 4- or 8-ohm loads, you'll have all the flexibility you need to build a dream system for your place of business.

The CSMA 2120 is even easy to operate when hidden away in a darkened cabinet, thanks to the illuminated rings around each dial on the front panel. The lights are signal-sensing, so each will glow green as soon as an input signal is detected. The mixer/amplifier is also compatible with remote volume control (not included) via twin RJ-45 ports on the back panel.
