Functional Block Diagram
The 9034 has a very flexible signal flow path and feature set that combines several products into one
compact package. This section diagrams the basic signal flow of your 9034 product.

Analog Audio
The 9034 supports 8 channels differential analog audio. The analog audio is converted in such a way as
to make +24 dBu (analog) equivalent to 0 dBFS (digital).
Discrete AES Audio Input
The 9034 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The
AES must have a nominal rate of approximately 48 kHz. Sample rate conversion is employed to
account for minor clock rate differences in the input AES stream and the input video stream. However,
the card does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.
