Notes:
• SDI embedded audio and the Merging Technologies' audio option cannot be used to capture audio simul-
taneously.
• VCube does not use the RS422 connector on the breakout cable currently.
• This card needs a HD 2K VCube because of the PCI-Express architecture. SD or early HD VCube cannot be
updated with this card.
Reference Input (video card):
• This BNC connector allows you to synchronize outputs to your house reference video signal (or black
burst). If you have a sync generator or central piece of video equipment to use for synchronizing other
video equipment in your studio, then connect its composite output here. When Xena outputs video it uses
this reference signal to lock to. For HD reference, use
• Tri-level Sync as defined in SMPTE 274M. For 1080i and 720p modes only, you may also use analog 525 or
625 black.
Sampling Rate
•The Composition Sampling Rate must be set to 48 KHz when the Xena audio channels are used for cap-
ture or playback.
• During capture audio monitoring must be done from the card outputs where audio inputs are connected.
