RP-L2
This application shows a CMA30 and a CMA120 being used in a retail store paging system. Channel #1 of the CMA30 is set for input from
the telephone paging line. The telephone system also provides a paging contact closure which is wired to the Mute/Chime terminals of the
CMA30. Channel #2 of the CMA30 is set for input from the line-level digital message repeater, and is assigned both as a priority channel
and manual muting of -20dB. Channel #3 of the CMA30 is set for input from the line-level background music source, and is assigned
manual and auto muting of -10dB. Channel #1 of the CMA120 is set for input from the warehouse paging microphone, which also has a
push-to-talk switch wired to the Mute/Chime terminals of the CMA120. Channel #6 of the CMA120 is set for input from the line-level Pre
Out of the CMA30, and is assigned manual muting of -40dB. Therefore, the digital message repeater will automatically mute only the
background music (-10dB), whereas, telephone paging will manually mute both the background music (-10dB) and the digital message
repeater (-20dB). These combined signals from the CMA30 are then fed to the CMA120 in the warehouse, where they are manually muted
by any warehouse paging (-40dB). RP-L2 potentiometers are wired to the Remote Level terminals of both the CMA30 and CMA120,
providing remote control of store and warehouse levels. The CMA30 and CMA120 are set for 'xfmr' output and are connected to 70V
distributed speaker systems.
