This application shows three CMA60s being used in a multi-floor office/hospital paging system. An all-call paging microphone and a
background music source are connected to an ADVANTAGE
®
DA28R, which distributes those signals independently to the three CMA60s.
Channel #1 of each CMA60 is set for input from line-level all-call paging, and is assigned as a priority channel. Channel #2 of each CMA60
is set for input from the respective floor paging microphone, and is assigned auto muting of -40dB. The push-to-talk switch of each floor
paging microphone is wired to the Mute/Chime terminals of the respective CMA60. Channel #3 of each CMA60 is set for input from line-
level background music, and is assigned manual and auto muting of -20dB. Therefore, local paging will manually mute the background
music only on that floor (-20dB), whereas, all-call paging will automatically mute background music (-20dB) and local paging (-40dB) on all
floors. The CMA60s are set for 'xfmr' output and are connected to 70V distributed speaker systems for each floor.

DIAGRAM SHOWS THE OUTPUT TERMINAL COVER REMOVED FOR CLARITY ONLY. THE COVER MUST BE INSTALLED WHEN THE UNIT IS ENERGIZED.
