The CX263 audio mixer is compatible with Cloud PM Series paging microphones. Alternatively, Mic 1 input may be configured to suit most OEM paging systems: paging may be activated by voice (VOX) or short-to-ground access connections, and Mic 1 may be configured to have priority over the Mic 2 to prevent announcement clashes. Additionally, one line input may be set to have priority over any other selected to facilitate connection of a digital sound store or similar device. This audio mixer can also be fitted with an optional RS-232 serial control interface as well as allowing remote music control, the interface’s command set permits remote control of other unit functions.
