Single-Channel Configuration
This configuration is used for spare device switching in single-program installations,
i.e. when a single LF-signal is fed to several power amps. In that case, only one DCS
422R module is being used per spare system, since the inputs of all power amps
included are connected in parallel. The output signal of a power amplifier that fails to operate is switched over to
the corresponding spare amp. The pilot tone signal is generated in the DCS 422R module.
