...The entire audio chain is powered from dedicated sockets that have their own dedicated line from the fuse box.The entire PC chain is powered from a Belkin UPS plugged into a different line from the box. ......I have disconnected every cord in and out of the back of the PC save for the line out to the pre-amp, the power cord, and the line in from the modem. Makes 0 difference.
OK, here's a more reasonable price with free shipping.Many places that sell it don't even mention the ground breaking aspect and simply refer to it as a "surge protector" but if you read the outer casing you'll see it is.
Wait, I just realized. You may still need that device I linked to, if you have cable TV or sat TV connected to that same audio system, even if the device isn't turned on. The offending ground loop can come from ANY device and ANY connected wire, be it AC, USB, RF, RJ45, ethernet, cable, sat., etc.
Fandango, I was able to locate that part you linked to locally for $18. I installed it, and it was a success!!!!! Thanks so much everyone, the noise is now gone from the system.I have a question, does this part at all degrade SQ? Like I said the goal is to install an E-mu 1616m to record a friends music for him, and don't want to be introducing something into the chain that will take away from their studio work.Again, thank you everyone! I was going a little crazy there and am starting to feel sane again.
