Audio Path
The output audio source selection consists of two sets of controls.
• Input Sample Rate Conversion (SRC) routing source selections
Each SRC source can be assigned to one of the following sources:
• AES In (1A/1B to 8A/8B) (with AES8 option)
• Demuxed audio (Group 1 channels 1/2 to Group 4 channels 3/4)
• Output Audio Source Selection for the embedded audio
Each output embedded Audio channel can be assigned to one of the
following sources:
• SRC (1a to 16b)
• In Pair (SRC1a+1b to SRC16a+16b) Sum
• TstTone 400 Hz
• TstTone 1 kHz
• TstTone 2 kHz
• TstTone 4 kHz
• EBU R68
• SMPTE RP155
• SRC1a+2a
• SRC1b+2b
• SRC2b+3b
• SRC2a+4a
• SRC2b+4b
(The parameters are listed on page 45.)
Seamless Sound Function
When used in conjunction with HDX6803+ or SFS6803+ in a de-embedding
mode, the HMX6803+ can provide an uninterrupted (“popless”) embedding and
de-embedding path for the discrete audio channels regardless of the presence or
input switching of the video, as long as a constant video standard is maintained.
HMX6803+/OP+HMX+ connected to HDX6803+/OP+HDX+
HMX6803+/OP+HMX+ parameter settings (embedding module):
Set the Seamless Sound Enable parameter (Processing > Audio) to Enable.
Set the Audio LOV Output Mode to Pass.
If an audio group already exists and you want to replace it, set the ADS Clean
parameter to Yes (Processing > Audio > Embedding).
The ADS Clean parameter removes all audio groups from the video stream.
