I've been slowly gearing up for recording on my computer direct from my amp. I have a Workingman's 8004 Head and a Soundblaster Live Drive that I use the front Line-In 2 input on. I tried using an instrument cable to go from the amp (Preamp Out) to the PC and it had HORRIBLE buzzing that came through in the recording AND the amp. My friend gave me an XLR to 1/4" to try out and I connected it to the Balanced Output to Line-In 2. There's still hum coming out of my amp's speakers but much less (a few decibles of hum) in the recording. When I use the ground/lift switch, it cures the humming of the speakers but the recorded signal has something like 30 decibles of hum. It goes freaking crazy. Anybody know what's going on here? Why would my speakers pick up sound from a one way output connection? Please help me. -Eric.
