Cobalt Networks 9034 사용자 설명서

••••  (V 2.0) 

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. 

The 9034 supports the complete range of modern SMPTE standard SD and HD video formats.

Notes:  

1.  All rates displayed as frame rates, interlaced (“i”) field rates are two times the number shown. 

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). 

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.
