So the thunderbolt port will handle audio in?
You don't even want to know how many audio channels a Thunderbolt port can handle.
... now that I said that,
I'm curious about how many audio channels a Thunderbolt port could handle.

And
here is the answer:
Q: What is the maximum number of audio channels available to and from the computer?
Connection, Sample rate, Channels (in and out)
Thunderbolt / USB3, 44.1 to 96 kHz, 128
Thunderbolt / USB3, 176.4 or 192 kHz, 64
USB2*, 44.1 or 48 kHz, 64
USB2*, 88.2 or 96 kHz, 32
USB2*, 176.4 or 192 kHz, 24
*The 624 and 8A provide 72, 36 and 24 channels over USB2 connection at respective sample rates.

And I'm guessing there is TB2/TB3 devices that allow even more channels.
