Blackmagic Design DeckLink Duo 2
The DeckLink Duo 2 has four fully independent 3G-SDI connections for capture and playback to a computer and supports SDI formats in SD and HD up to 1080p / 60. Four SDI inputs and four SDI outputs plus a tri-sync / black burst reference. The DeckLink Duo 2 behaves like four independent SDI cards but only takes one PCI-e slot in the computer. Duo is perfect for servers where simultaneous captures and playback are required per system. Duo 2 is compatible with Windows, Mac OS X and Linux.
