This application shows a MXA300 being used in a commercial/industrial paging system. Channel #1 is set for input from the telephone paging line, and is assigned both as a priority channel and manual muting of -80dB. Channel #2 is set for input from the security paging microphone, which also has a push-to-talk switch wired to the Mute/Chime terminals of the MXA300. Channel #3 is set for input from the line-level background music source, and is assigned manual and auto muting of -20dB. Therefore, telephone paging will automatically mute only the background music, whereas, security paging will manually mute both the background music and the telephone paging. The MXA300 is wired for transformer output and is connected to a 70V distributed speaker system.
