backup amplifier can serve for zone 1 to zone 4 actually. The below figure shows the concept of that.
Share the Backup Amplifier
In the figure, Z1~Z4 represent the normal amplifier for Z1~Z4, B1 is backup amplifier. S1~S4 are
switches to select path of audio signal coming from DSP processing. S5~S8 are switches to select
path going to Line A/B output. B1 can service for zone1 to zone 4 by controlling switches S1~S8. In
example, amplifier Z2 is fail, IDA8 control S6 and S2 to change audio path from normal amplifier Z2
to backup amplifier B1. The behavior of other channels are the same as channel2. A backup
amplifier can't serve more than one zone at the same time. In such limitation, for example, if
amplifier Z3 is fail, then there is no available amplifier for backup.
Advance Backup Amplifier Setup
There are more cost down solution of IDA8 backup amplifier setup. It is possible to let one backup
amplifier serve more than four zones. See the below figure, an Ateis Net system is consist of one
IDA8C and two IDA8Ss, there are 24 zones in the system divide into three backup amplifier groups.
For each group, there is an backup amplifier to redundant if any of normal amplifier in the group is
failure. To group zones, you need to wiring AMPI and AMPO between backup amplifier connectors.
red wires show the wire connections to group zones.
