9.5.3Multi channel interface and basic amplifier co-operation

The multi channel interface monitors the functions of the basic amplifier. Under certain conditions a fault with a basic amplifier channel will set a spare amplifier channel as a main amplifier channel.

The faulty main amplifier does not have to be in use for the spare amplifier to be used as the main amplifier. The software makes sure that the spare amplifier channel has the same setting as the main amplifier channel that it replaces. The spare amplifier channel does not become main if a main amplifier channel is disabled in the configuration.

A spare amplifier channel will not replace more than one main amplifier channel. If a spare channel is already being used as a main channel, and another main channel reports a fault, the second main channel is put on a waiting list for the spare amplifier channel. If more than two main channels are connected to the same spare channel, the first amplifier channel to report a fault will receive the spare channel.

When the first amplifier channel becomes available for use again, the spare channel takes over the functions of the second main channel until the second main channel becomes available.

9.5.4 Front panel LED indication

The front panel of the multi channel interface has LED indicators that show the status of the connected amplifier channels and the network status. See table 9.3 and table 9.4 for the description of the status LEDs.
