JBL CSMA 240 Commercial Series Mixer/Amplifier

The JBL CSMA240 is a commercial mixer/amplifier designed to handle audio needs in various professional settings with ease and reliability. It offers 8 input channels and 2 outputs, delivering up to 40 watts of peak power per channel, making it suitable for background music, paging, or announcements in environments like retail stores, offices, or restaurants.

This unit supports multiple speaker configurations, including 4 ohm, 8 ohm, 70V, and 100V systems, without requiring additional transformers. Each output features separate bass and treble controls, allowing you to fine-tune the sound to fit the space. The illuminated volume knobs make adjustments straightforward, even in dimly lit areas.

For microphone inputs, phantom power is available on all channels, and priority muting is built into channels 1 and 5 to ensure important announcements come through clearly. Voice-activated ducking automatically lowers background audio during paging, so messages are always heard without manual intervention. The AUX output lets you connect additional amplifiers if you need to expand your system.

Remote volume control is possible through RJ45 ports, which connect to wall-mounted volume controls using standard Ethernet cables. The CSMA240’s 1U rackmount design fits neatly into professional audio racks, and its fanless operation keeps noise to a minimum. Energy Star certification and RoHS compliance reflect its efficient and environmentally conscious design.
