Embedded Audio The 9085 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 9085 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 9085 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 9085 does not support AES input at 32 kHz,
44.1 kHz, 96 kHz or 192 kHz rates.
Discrete AES Audio Output The 9085 can provide 16 channels (AES pairs 1 thru 8) of discrete AES
audio on 75
Ω BNC connections.
(1) All rates displayed as frame rates; interlaced (“i”) field rates are two times the rate value shown.
