JBL CSM -21 2 x 1 Stereo Public Address Mixer

 

The JBL CSM-21 2 x 1 Stereo Public Address Mixer is a digital commercial mixer for conferencing, retail, and hospitality applications. The mixer features two stereo music inputs with bass and treble equalizers and one line input for connecting the mixer to a building's alarm system. It also features one microphone input with phantom power, gain control, and a ducker that can lower the volume of the music when making announcements.

The mixer also features one stereo output with a zone equalizer, an active crossover, and a separate subwoofer out. The unit does not require a computer to operate. Designed with a simple analog style control panel, you can switch between source 1, source 2, and remote control with the turn of a knob. An included security plate can be installed over the front panel to prevent changes to the unit's controls once configured.

The mixer works with optional CSM remote wall controllers, allowing you to remotely adjust the input source and volume level. Additional output zones may be added to the system by connecting multiple CSM mixers together using a Cat5 cable plugged into the unit's RJ-45 link ports. With the above features, the mixer provides flexible options for different sound applications such as in restaurants, retail stores, yoga studios, and other commercial establishments.
