Multi-Channel Configuration
This configuration is used for spare device switching in multi-program installations.
Input and output signals of the affected power amplifier are switched over to the
corresponding spare amp in case of power amp failure.
An equal amount of DCS 422R and DCS 423R modules is employed (a minimum of one of each). The pilot tone
signal is generated in the DCS 422R module(s) (generator active).
