Blackmagic Design UltraStudio Express, the original model with the first-generation Thunderbolt port. Used, unit only. 10-bit SD/HD capture and playback for Mac, powered over Thunderbolt, so no power supply is needed. No cables are included: you'll need a Thunderbolt 1/2 cable, and the analog connections require Blackmagic's breakout cable, which is not included. Newer Macs with USB-C/Thunderbolt 3 ports also need Apple's Thunderbolt 3 to Thunderbolt 2 adapter. Please confirm that Blackmagic Desktop Video supports your OS before buying.
