DeckLink Quad 2 features 8 independent SDI capture and playback channels in a single card! Fully compatible with the previous 4 channel model, this new model also allows 4 independent capture and playback channels but now also includes 4 extra channels that developers can use for configuring the card in any combination of up to 8 capture or 8 playback channels.
This means DeckLink Quad 2 allows each of the 8 3G-SDI BNC connectors to switch direction between capture or playback in SD and HD up to 1080p60 and as a complete independent channel.
