A: The answer is yes. you can capture video and audio from different source and it will combine during stream.

Q: 3. Many capture devices specify 4K input but are limited to HD output. Description for this unit is not clear to me. Does this unit provide 4K recording output?

A: Yes it does. This capture device will record up to 4096xx2160 on your computer.

Q: 4. Will the USB port be fast enough to transmit 4k to the computer? I thought only Thunderbolt 3 could handle that.

A: Yes, this supports 4K through USB 3.0.

Q: 5. The Audio input is labeled as MIC, What are the input specs? Will it also work with line levels? (consumer 0.35V)?

A: In terms of specifications provided by the manufacture, what is listed from the manual is "The Mic input can also act as a mono line-level input (giving 0dBFS from ~0dBV with the control at ‘0’), and has ~45dB of gain for handing mic-level signals."

Q: 6. Could I use this devise to record video a black magic ursa pro? Bypassing CFast and the SD cards?

A: You can record video from Blackmagic Design URSA Mini Pro via the USB Capture SDI 4K Plus. Just know that while the device supports SD/HD/3Ga/3Gb/3Ga-DL/3Gb-DS/6G (SMPTE 2081), it does not support 12G SDI.
