- Mixer amplifier
The JBL® CSMA 240 Series of Mixer-Amplifier is a professional tool with a sleek industrial look that is designed and built for commercial sound applications. The CSMA 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 70 volt and 100 volt distributed audio systems without the need for a separate transformer. In addition to balanced mic/line inputs, unbalanced RCA inputs and speaker connections, all units include RJ45 connectors for use with JBL CSR-V in-wall volume controls.
