Program Play

Enable: Allows the input to Main In to vary from the nominal 48 kHz sample rate. Permits the decoder to operate with a VTR in Program Play mode. As the sample rate varies from 48 kHz, the decoding latency is no longer exactly one video frame. The P in the display below reflects that Program Play is enabled.

Disable: The sample rate of the Main In input must be 48 kHz for the DP572 to decode.

48 kHz Pull Down

See 48kHz Pull Down on page 3-10.

PCM Bypass

Enable: Allows smooth transitions between decoded Dolby E and PCM audio.

Disable: Audio outputs are muted until a valid Dolby E stream is received at the Main In input. This is useful when editing on a VTR while decoding with the DP572.

Bypass Metadata

This feature is only relevant if PCM Bypass mode is enabled.

Disable: While the DP572 receives PCM input, no metadata is output.

Enable: While the DP572 receives PCM input, a default set of metadata parameters more appropriate for two-channel audio is sent instead of the Dolby E stream’s metadata.
