Demux Ch 1/2
,
Demux Ch 3/4
, etc. (Output > Audio Source Select > AES Audio).
For optional minimum propagation delay, set the

Dolby-E Automatic Header Alignment
When you embed Dolby E audio, the module automatically adjusts input audio delay such
that the Dolby E header resides on the line specified by the
Dolby E Start Line
parameter,
shows the ranges and default values for the
Dolby E
Start Line
parameter.
In order for Dolby-E automatic header alignment to operate correctly, the following
conditions must be met:
The
Audio Track Video
parameter must be set to
No
.
If the Dolby-E source is from an AES signal and the
Frame Sync Mode
parameter is set
to
Sync Mode
, the module must be locked to the same reference video source as the
Dolby-E source (when
Genlock Video Locked
is
Yes
).
If the Dolby-E source is from an AES signal and the
Frame Sync Mode
parameter is set
to
Delay Mode
, the input SDI must be frequency locked to the same reference source
as the Dolby-E source.
If the Dolby-E source is from incoming embedded audio,
Frame Sync Mode
must be
set to
Delay Mode
.
