Decklink Duo - PCi-Express - Independent dual channel SDI capture and playback on a single x4 lane PCIe card plus reference input.

3 Year Limited Manufacturer's Warranty.

DeckLink Duo is perfect for developers who need two completely independent capture and playback streams in and out of a computer, as both capture and playback channels are completely independent. There are two SDI inputs, and two SDI outputs plus a common tri-sync/black burst reference. DeckLink Duo appears as two independent SDI cards to the computer, but only uses a single PCI Express slot. DeckLink Duo is perfect for servers where there are multiple streams or simultaneous capture and playback per system. DeckLink Duo is compatible with Windows™, Mac OS X™ and Linux™.
