First off, -1 star for lacking IEC power cable. Who makes a device and doesn't include the power cord these days? I mean, I have dozens of them lying around somewhere, but I had to go find one. So yes, minus 1 star. (the box doesn't even include provisions for storing one, so I suspect it's intentional) After that, though, this box is pretty good. It works like it's supposed to, but like all Blackmagic devices it introduces a 700ms delay to both video and audio on passthrough (expected, hoped otherwise). I'm also tethered to my computer with a Thunderbolt 2 optical cable going into a Thunderbolt 3 adapter. Works flawlessly.

The Blackmagic Design UltraStudio 4K Thunderbolt 2 is an external 1RU/table-top I/O device with two 20Gb/s Thunderbolt ports. It captures DCI 4K 4:2:2 or UHD 4K YUV 4:2:2 by single-link 6G-SDI up to 30p and by dual-link 6G-SDI from 50p to 60p; 1080p RGB 4:4:4 by single-link 3G-SDI; 1080p 4:2:2 by single-link HD-SDI; 1080p 4:4:4 by dual-link HD-SDI; and DCI/UHD 4K 4:2:2 by HDMI. 4K can be input/output compressed and uncompressed. The SDI inputs also support dual-channel 2D/3D stereoscopic workflows. UltraStudio 4K is capable of hardware-based HD down/up/cross conversion.
The other connections are Component and Composite on BNC, 2-channel analog audio on XLR, 2-channel AES/EBU audio on BNC, timecode input and output on XLR, Blackburst and Tri-Sync and RS-422 deck control. A color LCD and six quick-access video and audio input buttons are built in on the front panel.
