Mixer offers fixed I/O, pre-configured architecture, full stereo or mono operation, flexible routing and control of multiple audio sources. The CSM-32 features three stereo music inputs with gain control and clip LEDs, and two stereo outputs with active crossovers and dedicated subwoofer outputs. Zone Remote ports 1 and 2 facilitate connection of the CSR wall controllers, which can provide source selection and/or volume control in each output zone. Source select per zone, music level per zone, and mic level per zone can also be controlled on the front panel. For additional control, two logic inputs facilitate page steering and music muting via contact closure.
