Redback® A 4469 Audio Switcher

1.0 OVERVIEW

The A 4469 Audio Switcher provides a Microphone level or Line level output which can be connected directly to the inputs
of up to four amplifiers to provide up to four zones of audio. A BGM input on the rear of the A4489A directs background
music to all zones until over-ridden by zone paging.
Zone paging is achieved with the addition of A 4660 paging consoles.
The A 4660 paging console provides up to 4 zones of paging, and allows the operator to manually select any zone or
any combination of zones. A pre-announcement and post announcement chime is available at the paging console and
through the PA system. Provision has also been made on the A 4660 for a local BGM input for background music.
Connection between the A 4660 and A 4469 is via a Cat5e/6 cable which carries power and the balanced audio output
from the microphone.
