i've read stuff about certain peices of equiptment being balanced and unbalanced and stuff like that. on my 8-track, fostex mr-8, I have two balanced XLR inputs and two unbalanced 1/4" inputs. Now, I just got a mixer (Soundcract Series 1S) and someone said something that its pin 3 hot. I don't know if that's unbalanced or balanced... can i plug my 8-track into the mixer via the XLR output on the mixer? if they're not balanced, would that mess it up?
