Audio Routing w ithout Backup Am plifier
The figure below(Audio Routing with Backup Amplifier) shows the amplifier backup in the case of
audio routing. When an error with the normal amplifier is detected by the IDA8C, the IDA8C will
change the audio path from the normal amplifier to the backup amplifier and generate a fault to warn
the user that there was an amplifier fault detected by the system. Please correct this issue.

Share the Backup Amplifier:
In most of cases, two amplifiers should not fail at the same time. The probability of more than two
amplifiers failing is significantly low. It is not necessary to have a backup amplifier for each zone as
in most cases the backup amplifiers are waiting for the normal amplifier to fail. If one of the normal
amplifiers fail, one backup amplifier can take over immediately. In the meantime, the unit will quickly
switch from the failed amplifier. During the time that the amplifier backup engages, it is rare to have
another amplifier fail. Based on this concept, the IDA8 system provides a flexible mechanism for
amplifier backup. One backup amplifier can service multiple zones. The preview figure demonstrates
how a backup amplifier works when a normal amplifier connected to Zone 2 fails. The backup
