Model DP579 Dolby Tri-Level Sync Interface
6
The DP579 can be permanently connected to the Dolby E encoder and
decoder as it will detect standard black and burst reference signals, and
pass them directly through to the output connectors.
The DP571 Dolby E Encoder will need to be configured to the video
frame rate present at the DP579 input. This setting is made in the
Operating Mode/Frame Rate setup menu.
The DP572 Dolby E Decoder will automatically detect the appropriate
frame rate from the DP579.
Both the DP571 and DP572 will indicate the presence of a valid Dolby
black signal via a green VRef LED on the front panel. If the Vref is
yellow this indicates a valid video reference, however this reference
does not match the Frame Rate setting in the case of the DP571 or the
frame rate of the input Dolby E stream in the case of the DP572. A red
LED indicates an invalid reference or no reference signal.
