Avaya Bogen PCM Paging Control System Installationsanweisungen

The PCM system is very flexible in how it can provide background music throughout the system:

The BGM SRC terminals are used to control background music operations when using a single power amplifier
that does not provide a separate music input. This feature is only used when a single amplifier will be used for both
background music and paging (background music is lost in all zones when a page is made).

NOTE:  This input and its associated control is not used when using amplifiers with separate music inputs and
paging control terminals because background music is supplied directly to the amplifier.

1. When using the BGMSRC (background music source) input on the PCMTIM as input for background music, the
music is muted to all speakers when any zone is selected. The source input signal is line level.

2. When the HPBGM (high-powered background music) input on the PCMCPU is used, music is muted only in the
zone selected. The source input has to be an amplified signal.

3. When the LPBGM (low power background music) input on the PCMCPU is used as an input for background
music, music is muted only to the zone selected. In this application, either amplified speakers or an amplifier per
zone is used. PCMZPM output power switch is set to LO-PWR. The input background music is line level.

4. When the Local BGM input on the PCMZPM is selected as input for background music, music is muted only to
the zone selected. An amplified signal is required at this input if using 70V speakers. 

NOTE: When you want to mute the background music only to the zone in which you are paging, use 2, 3 or 4.
