JBL / CSMA 240

The CSMA240 is a power amplifier with an 8-channel mixer function. It is equipped with microphone/line input terminals that can switch signal levels and supply 27V phantom power, as well as a line input terminal for directly connecting a CD player or other device. It supports high-impedance connections and also features a high-pass filter function to prevent speaker transformer saturation.

This all-in-one power amplifier with built-in mixer makes it easy to build a broadcast system. Packed with a wide range of features in a compact housing, it allows you to set up a broadcast system simply by connecting microphones and speakers. Furthermore, its minimal operation makes it possible to achieve high-quality sound reinforcement even in stores, facilities, and work spaces without a dedicated operator.
