PCMCPU

6-Zone System with One-Way Paging With Mixed

High-Power & Low- Power Zones and Local BGM

In the application illustrated on the next page, both high-power passive speakers

and low-power amplified speakers are used in the same system. Two separate

sources are used to supply BGM. In this configuration, background music will not

be interrupted in all zones not being paged.

The right-most PCMZPM module is set for high-powered paging, and its

OUTPUT switch is in the HI PWR position. Only passive speakers may be

connected to this module. This module is also being supplied by a local back-

ground music source. Note that the BGM source is amplified; the same type of

signal that the paging amplifier produces. The high-power BGM source is wired

to the module's LOCAL IN and RT terminals, and the GLOBL BGM jumpers have

been moved to the OUT column.

The other PCMZPM module is set for low-power paging. Its OUTPUT switch is in

the LO PWR position. Background music is being supplied to the low-power am-

plified speakers by another low level BGM source. The BGM source is connected

to the LPBGM terminal, which supplies BGM to all low-power PCMZPM modules

having their GLOBL BGM jumpers in the IN column.

The centralized paging amplifier's input is connected to the PA IN & RT terminals.

The amplifier's output is connected to the PA OUT & RT terminals.
