Applications
A typical classroom installation would utilize the AA-PPRC
inserted between the presentation system amplifier and loudspeakers with a trigger input from the school’s 25V paging/
intercom system loudspeaker located in the same classroom.
When a page occurs the presentation system will be muted
for the duration of the announcement and will resume when
the page is complete. (see page 2)
Other applications include zone page management for new
or existing systems and priority switching of line-level audio
sources. (see page 2)
General Description
The AA-PPRC Priority Page Relay Controller is a two-input, by
two-output speaker level switch system rated at 350 watts
per channel.
Inserting unit into the signal path between an amplifier’s
output and the speaker load allows system muting based
upon a variety of external trigger sources including speaker
level audio (3V to 45V), line level audio (10mV to 3V), external
contact closure or 5 to 24 volts DC. Release time of the relay
control is variable from 0 to 30 seconds.
