I was trying to connect an Aguilar DB750 through the XLR output on the front to my computer (nothing fancy, just a TerraTek internal sound card). I had to convert the XLR to jack and the jack to RCA to be able to do so. However, the signal is quite low and I hear a huge constant noise (I figure it's the fan, though I'm not an expert enough to know). I have also tried the "Tuner out" jack output, but with the same results. I haven't used this amp yet in a live situation so I don't know if the noise is present when connected to the PA. I'm trying to record stuff for some of my students and it can't be done like this. I had no such problem with my Gallien Krueger 1001-RB's direct out, so I don't think it's some interference special to my apartment. Is this only my home setup's fault? Is there a way to eliminate this noise? Or, at least, is there a way to control the output level? I've tried but neither the preamp volume nor the poweramp volume seem to have an effect.
