Hi all, I know these auto on power circuits generally leave a lot to be desired, but mine works surprising well, that is till the central air powers on. That will cause my amp to turn on while in auto power on. Is there anything I can do to suppress this voltage spike? I tried an APC surge suppressor, but that does nothing. Is there anyway to use the triggers from a computer?
Ok, I thought maybe the input cable to that amp was picking up noise, so I put a very high quality shielded cable on it. same problem,the amp comes on if the air conditioner turns or, or I flick the wall fan switch, and the amp goes on. So, I tried braiding the cables. same problem. Next I tried my iPod, and that works fine. Soon as I plug the cables back into the Mac I get the problem. So I guess the noise is coming straight through A/C connections. Is there anything (short of finding another outlet), I can do to filter this out?
Since there seems to be noise on the power line, you should try adding a power line filter/conditioner. One of our CMX's might do it. (Note that, even if you have a surge suppressor, they don't all include noise filtering.)
You will want to connect both the Mini-X and the computer's AC adapter to the filtered outlets.
