Using the Status Port to Select Voiceover and Switched Modes

The PCM Input channel routing can be changed via the Status port between Voiceover and Switched Out modes, which are generally used when Dolby E is part of a distribution system without a VTR (i.e., a network feed to an affiliate).

Voiceover mode mixes the PCM input over the main program audio.

Switched Out mode replaces the main program audio with the PCM input.

These modes can be controlled from the front panel, serial remote, or Status port. See “Output Routing” on page 8. for a complete explanation of other PCM Chan Config Output Routing modes not accessible to change via the Status port.
