Integration with Background Music and Emergency Notifcation systems
Many Public Address systems also incorporate zoned background music playback and the
requirement for an Emergency Notifcation override; Barix Simple Paging supports both of
these features per device, enabling the creation of a multiple zoned background music
environment.
Audio Volume: Typically Emergency messages are required to be at a higher volume than
BGM or standard Paging announcements, with Simple Paging, each audio source has its own
associated volume.
Audio Format: The incoming audio for BGM and Emergency Audio must be contained in an
RTP stream in a Barix supported audio format: mp3, PCM uLaw/aLaw.
Audio Source Priority:
Emergency audio has the highest priority and will override any other audio source,
A Paging message has middle priority – will interrupt BGM playback, but in turn be dropped if
an Emergency Announcement is made
Background Music has the lowest priority and only plays if no other source is active.
Refer to chapter 8 for details of how to confgure individual Simple Paging devices to support
these services.
