Backup Amplifiers Connection
The connection of amplifiers for backup. In above figure(Basic Amplifier Connection), B1, B2 are
backup amplifiers. There two connectors for each backup amplifier. Follow the wire, audio signal
start from the AMP I connector, goes into the amplifier's input, then gained by amplifier and input to
AMP O connector. The following figure is an example of backup amplifier connection.
4.1.5.2 Amplifier Backup
Basic Concept
IDA8 system apply a flexible mechanism for amplifier backup. Before dig deeper inside the rule of
amplifier backup, let's understand the basic concept of it. For most of case audio go through the
normal amplifier, once the normal is failure IDA8 will switch to backup amplifier to make sure the
system still working. At this time, the technician should analysis the problem, of course, to replace
the bad amplifier with good one. The figure(Audio Routing without Backup Amplifier) show the
general case of audio routing using normal amplifier, the number in figure is the sequence of audio
path.
