Embedded Audio The 9083 supports all four groups (16 channels) of embedded audio at
full 24-bit resolution in both SD (with extended data packets) and HD.
Analog Audio The 9083 supports 8 channels of balanced (differential) analog audio.
The analog audio is encoded such that a +24 dBu input is equivalent to
digital 0 dBFS.
Discrete AES Audio Input The 9083 can accept 16 channels (8 pairs) of discrete AES audio on
75
Ω BNC connections. Sample rate conversion can be employed to
account for minor clock rate differences in the AES stream and the
input video stream.
Note: The AES signal must have a nominal rate of approximately
48 kHz. The 9083 does not support AES input at 32 kHz,
44.1 kHz, 96 kHz or 192 kHz rates.
Discrete AES Audio Output The 9083 can provide 16 channels (8 pairs) of discrete AES audio on
75
Ω BNC connections.
(9083-DEC only) Dolby ® E/
Dolby ® Digital™ Audio Input
Decode
The 9083-DEC provides up to 10 decoded AES channels when valid
Dolby
® E or Dolby ® Digital™ audio is received on either discrete AES
or embedded inputs with corresponding metadata.
(1) All rates displayed as frame rates; interlaced (“i”) field rates are two times the rate value shown.
