Thanks, Mark. That actually does help. I am a bit frustrated, though, that I can't seem to find the fabled "full manual" anywhere, and I suspect it doesn't really exist. I know that this interface doesn't have anything unusual (at least probably), it would be nice to have a real reference to check these kinds of questions. Anyway, I'm going to see what results I can get with standard insert cables and that'll probably answer my questions as definitively as I can hope for.
I've been trying to find an answer to a fairly basic question about the inserts on the UMC204HD and if anyone could help I would be grateful. I'd like to know if the inserts are stereo TRS jacks or mono (or something else if I've completely missed the boat). Thanks in advance for any info you can provide.
