Functional Block Diagram
The 9034-SD 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-SD product.

Supported Audio and Video Formats
Input and Output Video
The 9034-SD supports both NTSC and PAL SMPTE formats.
Raster structure | Frame Rate |
486i1 | 29.97 |
575i1 | 25 |
Notes:
1.All rates displayed as frame rates, interlaced (“i”) field rates are two times the number shown.
Analog Audio
The 9034-SD 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-SD 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.
Discrete AES Audio Output
The 9034-SD can emit 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES clock rate will be precisely locked to the output video rate.
