its a shure pg57, and i dont thknk it requires phantom power. nothing is said about it in the manuals.
as for the min and line-in being selected, i only have one, like you said, and it still is not working.
my computer is a 2002, so it might be incompatible with what im using, but probably not. (i dont know, im computer stupid)
