7. BACKGROUND MUSIC INPUT
The OPM-3SM allows for a background music source to be mixed with pages
and pre-recorded messages. Background music is muted when pages or pre-
recorded messages are played to the audio output. The BGM Level control
allows you to optimize the level music sent to the audio output.
8. AUDIO OUTPUT
The audio output of the OPM-3SM is the audio interface for your zone controller,
amplifier or public address system. All audio from the paging channels, priority
input, messaging system and BGM input is routed to this output. The OPM-3SM
manages stored pages on a first in, first out basis. This means that pages will be
played in the order they were successfully completed and or triggered,
independent of the particular input. Only the priority input has the ability to
interrupt the playback queue. In the case of a priority page, the system will pause
the playback queue during the priority page, and then continue when the page is
complete.
