from embedded SDI passed into the egress transport stream ( IP, RF, ASI ). 
To enable Audio passthru for Audio 1: 
 

Step  Action 

On the Audio -> Encoder 1 subtab in the Web GUI Control Application, configure 
the 

"Audio Mode"

 for 

<PASSTHRU>. 

Configure the 

“Audio Input”

 for 

<SDI>

.   

Select the type of audio from the “Type” drop down. <

Dolby Digital

>, <

Dolby 

E

>, or <

Linear PCM / E2

>. 

note:

 If Dolby E or Dolby Digital is valid at the input, the bit depth and bit rate 

are automatically determined after clicking Apply. 

On the 

“PID”

 tab, type in the desired Audio PID for 

“Audio 1”

 

Common Passthru Problems: 

Dolby E Line Placement and/or Dolby E Continuity Count Errors: 
Dolby E audio compression technology is designed so that 1 Dolby E audio frame 
corresponds to 1 Video frame.  This 1:1 ratio of video and audio timing was designed to 
assist in Video editing and seamless cuts without losing audio data.  Due to the crucial and 
sensitive timing, Dolby E encoders must have a reference phase locked to the video.  In 
other words, the SDI video timing feeding the encoder must match the same composite 
reference timing that is connected to the Dolby E encoder.  A simple black burst generator 
that does not share the same SDI video timing will not work to source a Dolby E encoder.  A 
composite video reference that shares the same timing as the video source should be used. 
The encoder preserves audio and video timing as it is presented.  If the audio timing does 
not match video timing at the inputs of the encoder,  there will be line placement errors 
and/or CRC errors seen on a decoder. 
 
No Detection of Dolby E / Dolby Digital, Front Panel shows “DE ---”, “DP ---”, “LP ---”: 
The encoder will automatically detect the bit depth of Dolby E ( 16 / 20 bit ) and the bitrate 
of Dolby E / Dolby Digital.  If Dolby E is selected and Dolby Digital is presented, the encoder 
will change automatically and vice versa.  If Dolby Digital is selected and Dolby E is 
presented, the encoder will change the configuration automatically.  If the front panel shows 
dashes for the detected bitrate ‘---’, Dolby is not being detected.  This is most commonly 
due to a mis-configured SDI Audio Matrix or Dolby not being present on the specified input 
pair. Look at the SDI signal on an SDI analyzer to verify that Dolby is present on the pair 
intended. If an SDI analyzer is not available, one troubleshooting tip is to set the mode to 
ENCODE.  If silence or regular audio is heard on the decoder,  a compressed bitstream is 
not being presented on the corresponding input.  The SDI matrix can be changed to each 
pair without restarting the encode session.  Once hash is heard, then a compressed 
bitstream should be present.  Set the mode back to Passthru for the automatic detection 
mechanism to configure the Dolby type and bitrate.
