A computer UPS will not help and could makes matter worse. Computers have different power needs. You would need an audio power center. It could be the preamp causing the noise as well as the amp. If you switch the pre-outs left and right, does the sound then come out the other channel? If so, it is the preamp.
Help, Strange Static Sound Recurring
I am a newbie. I have a nice hand-me-down system (from my Dad), a Jeff Rowland Model 1 Amp, an Audio Research LS3 preamp, Thiel 3.6 speakers, and if it matters, a Theta Data Basic with a Theta DS Pro Basic III.
When I set it up, it was fine. After a few weeks, I awoke to hear loud white noise (static) coming from one channel. I had left the system powered up, but the amp was off and the static persisted. I could not turn the amp on. When I would push the power button, it would light up, but would not "catch" and stayed unlit.
I called Rowland, and sent the unit in to them. It checked out perfectly. I hooked it up again and it was fine, only to repeat the problem. The Rowland people were flummoxed. They had played it continuously for a long time with no problem. I sent it off again, but no problem found.
I talked with a local (Minneapolis) audio guy who speculated that it could be that the power coming into my house is weak or inconsistent. I then tried a computer UPS (uninterruptible power source), and I thought the problem was solved, but alas it recurred.
Someone at one point mentioned that perhaps the 3.6's were a bit much for the amp, but he wasn't saying that was the cause.
At times I have unhooked the speaker cords, swapped channels, changed fuses, etc. Sometimes, unhooking and then reconnecting the speakers seems to make it work, but then after a few weeks, here comes the static again.
Anyway, it is frustrating and the wife wants me to sell the whole system. I just bluebooked it at 5K. I might do so, but I'd love to solve the problem.
Any thoughts? Anybody wanna buy it?
