It's plug and play, I connected my DSLR with HDMI output for the feed and it worked straight away in OBS. I have 2 others from other pass through brands that are $50 and $100. Actually I don't really like the $100 because the colors are too garish it looks fake. This one is similar to the $50, a little low contrast, which I prefer (neutral). Now it has a slight delay. I calculated it between 10ms and 15ms. It's barely noticeable, but it's enough to make you think something's wrong when you see someone talking up close. In OBS, I simply added a 15ms delay to my mics and that was it.
