The JBL CSMA 240 can be your best friend if you're setting up a sound system for your restaurant, retail store or other business. 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. The CSMA 240 is even easy to operate when hidden away in a darkened cabinet, thanks to the illuminated rings around each dial on the front of the unit. The lights are signal-sensing, so each will glow green as soon as an input signal is detected. The mixer/amplifier is compatible with remote volume control (not included) via twin RJ-45 ports on the back panel. With two channels of 40-watts each, stable from 2 to 16 ohms, you'll have all the flexibility you need to build a dream system for your place of business.
