Hi All.
I currently use my computer for various DSP functions - EQ, XO, phase correction, volume control. The problem, although my soundcard measures amazingly (Asus Xonar D2), it has ground loop problems - in particular, I can't get it to shut up! I've tried a number of different things, and I've decided to try using transformers on the output.
I've already got six Edcor wsm 10k/10k line matching transformers. I'm currently working up an opamp output stage for each transformer, because I assume I can't just leave the secondaries of the transformers flapping in the breeze. Correct? I don't really want to, but I think I have to.
The schematic is mostly done, I'm doing the layout now. I'll post them when I can. A lot of trouble for a little ground hum...
Any feedback would be appreciated!
