I have an problem with my Apogee Duet, specifically Line 2 (set to XLR, no phantom)
When I plug a dynamic mic into it and crank it to it's "normal" level (60+), I start getting this nasty hum:

It does NOT exist on Line 1.
I've tried testing this with different XLR cables and the problem replicates. It sounds a lot like something's ungrounded but since the problem in only on Line 2, I assuming maybe that cable has gone bad?
This kind of stuff is totally out of my wheelhouse so if you have any troubleshooting suggestions, they'd be most welcome!

Apogee are located in Santa Monica and I have had great experiences with thier customer support. I would give em a shout tomorrow.
BTW - I fixed the problem with the mic; as it turns out, it was simply that the XLR base screw had become loose. Once I tightened that back up, it also re-ground the unit as a whole. Of course, once I solved that problem is when I discovered the problem with the Duet.
