This bundle includes everything you need to get a Quad2 working on a modern Mac. The Startech Thunderbolt 3 PCIe Expansion Chassis is an external PCIe enclosure with a Thunderbolt 3 port (and cable included). Once you install the Blackmagic Decklink Quad 2 into the chassis and plug it in to your computer, you need only install the Blackmagic drivers and you're up and running!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 completely independent channel.

NOTE: You will likely need adapters to go from the DIN connector to BNC (available here). Also, the chassis and the card are shipped separately and will arrive in multiple shipments, perhaps on different dates.
