The Decklink 4k Extreme (regular and 12G) have inputs A and B. Those models are not multi - channel and do not function like the Decklink DUO or Quad. The A and B connections are for dual link support or 3D stereographic support.

The output are the same scheme with A and B or alternately, A can be Fill and B can be Key for graphics support.
