Description

JBL CSMA 240 is a mixer/amplifier with eight mixer-channel inputs and two output channels. It’s capable of reaching 40W of peak power with 5W per channel. The CSMA 240 Mixer/Amp offers unmatched ease of use, with a clean, front panel featuring only volume controls for each channel, master volume adjustment, adjustable bass and treble controls and a power switch. All the volume controls are surrounded by an illuminated ring, making them easy to see and operate in darkened environments. The amplifier can drive 8 ohm and 4 ohm loads and can be used with 70V and 100V distributed audio systems without the need for a separate transformer. In addition to balanced mic/line inputs, unbalanced RCA inputs and speaker connections, the unit includes RJ45 connectors for use with JBL CSR-V in-wall volume controls. This Commercial Series mixer/amplifier features a universal power supply which enables the ability to accept AC voltages from 100 to 240 VAC, 50/60Hz.
