There was nothing I could find on the Focusrite page that addressed this question, and I found no easy way to contact them. Doesn't the LR in XLR stand for Left/Right?
And there was a mention in some of the FAQ about using a stereo mic, but not in the context of my concern.
There are two other glimmers of hope I will cling to until dismally disappointed.
1. The possibility of a single patch-cord to XLR adapter that may allow both channels to go to the two Ins--one to the 1/4" and the other to the XLR.
2. There is a "digital out" on the KURZ that looks quite a bit like an XLR connection. I suspect it was intended to go to a DAT or similar, but I don't know what actually leaves (analog audio, or digitized audio, or something else.)
Anyway, I've contacted Sweetwater and hope to get some kind of answer soon.
Thanks for the kind replies.
