I'm sure this has been covered in numerous previous posts, and I apologize in advance for not having read any of them or looked for a YouTube video that *might* be able to answer such a seemingly simple question (I'm just overly impatient). I can't seem to figure out which in/out in an audio track (and in Reaper's audio preferences) has to do with the "Digital I/O" 'In' jack where the XLR male end plugs into. Thank you for any answers!
