Hi, I've recently borrowed a friend of my friends Behninger XENYX 1002b non powered mixer. The reason was to test it recording drums, and acoustic live recordings. I've successfully recorded drums and acoustic with mics. But I can't seem to get the line ins or mono ins to pick up the guitar/bass/keys. I assume that would be the run in for the instrumentals. I don't have the instructions, the guys out of town and this is why I'm using it. Does anyone have any idea how to pick up the instrumentals? My friend said I may need guitar to mic output. He said the board may not pick up simply guitar input, and as I said before, I need an adapter to make the guitar input to a mic input. If anyone knows if this is or what is my problem, please let me know.
