Switched Out: Replaces the Program 1 audio with the PCM input. The PCM Dly
Output is muted. Switching is accomplished with a smooth crossfade.
Main In can be PCM or Dolby E.
Voiceover: Mixes the Program 1 audio with the PCM input. The PCM Dly Output
is muted. Main In must be Dolby E for Voiceover to function properly.
Delay Out: Matches the decoding latency of the Main In signal path. This is used
when the decoder is connected to a VTR to synchronize Dolby E en-
coded audio with non-encoded PCM audio. This is the default setting.
External Ctrl: Puts the DP572 in a standby state waiting for commands from the
Status port.
