Fig. 53: Example of a backup amplifier concept: Typical fault
The figure above shows a typical fault in a system. One channel on the
amplifier (1) fails. After several seconds, the 'Digital audio matrix (4/4/16)' detects
the error and reports it to the backup master.
If no other errors were reported previously, analog audio outputs 3 and 4 of the
backup master take over the audio function of analog audio outputs 1 and 2 of the
'Digital audio matrix (4/4/16)'.
The backup amplifier (3) strengthens the signal to 100 V and transmits it to all
'Digital audio matrix (4/4/16)' connected in the backup configuration.
The relay matrix of the 'Digital audio matrix (4/4/16)' toggles from the 100 V inputs
to the 100 V backup input (4). The loudspeaker lines (5) connected to the
amplifier (1) are now operated by the backup amplifier (3).
