Question

I would not be using both inputs at once, of course, but need to know if both inputs can have cables connected permanently.

Answer 1

I think like most of the other similar gear, plugging in the trs will bypass the xlr.

Actually, I stand corrected. The instrument jacks on the front are the only ones that disable other inputs. So if you are just hooking up in the back, you should be able to use both.
