Overview
1.0 OVERVIEW
1.1 INTRODUCTION
This unit is a very versatile cost effective public address/background music control system which provides audio to up to 16
zones. Background music which can be selected to play through any zone is muted when general paging occurs or when
an evacuation input overrides the system.
Operation is as follows:
Background music
is piped to any zone which has been selected to have background music via switches on the front of
the A 4585.
General Paging (via optional A 4586 paging station)
will mute the background music to the zone paged or all zones
depending on the setup configuration. The paging audio will then feed to the selected zones.
A 4575 RJ45 Input
mutes background music to all zones. This is a vox enabled input which can be adjusted via a vox
sensitivity control. The audio from the A 4575 will then feed to all zones.
Evac Input
mutes background music to all zones. This input has the same priority as the A 4575 RJ45 input. This input
is a vox enabled dual RCA input adjusted via a vox sensitivity control. The audio from the Evac input will then feed to all
zones.
