Option 3 : One Zone Amplifier using Mic or Line Level Signals and individual speakers for each zone
The audio from the paging console/s is fed down the Cat5e/6 cable to the A 4469 audio switcher. Take the line level
(1V balanced signal) from the "Line Out" terminals or the low level balanced signal from the "Mic Out" on the rear of the
A 4469 and feed them into the audio inputs of the zone amplifer as shown in figure 5. (Note: The Zone Amplifier can be
up to a maximum of 500 Watts). The speaker output of the zone amplifier is then fed into the "Audio In" terminals of the
audio switcher.
The audio from the "Zone 1" to "Zone 4" terminals are then fed directly into the speakers to provide the audio for the
four zones. Background Music can be supplied to each zone by connecting a Background music amplifier to the "BGM In"
terminals.
