JBL / CSMA 180

The CSMA180 is a power amplifier with a 4-channel mixer function. It features microphone/line input terminals that allow for signal level switching and 27V phantom power supply, as well as a line input terminal for direct connection of CD players and other devices.

An all-in-one power amplifier with a built-in mixer that makes it easy to set up a broadcast system. Packed with features in a compact chassis, it allows you to build a broadcast system simply by connecting microphones and speakers. Furthermore, because it requires minimal operation, high-quality sound reinforcement (SR) can be achieved even in locations without a dedicated operator, such as stores, various facilities, and workspaces.
