My current setup requires the ups (battery backup) to be near a klipsch subwoofer (promedia 4.1). Would that have any kind of interferences? Thanks.

The generator company suggested that we use a noise suppression device. Surge protectors have an EMF/RFI rating, but some are listed as 150KHz to 100MHz and others are listed as 40 to 80 dB.

Which would be better for removing “snow”/interference from the electronic equipment when using a generator? Or what would be recommended rating?

I have a fairly complicated setup, and when I moved and re-hooked everything up, I now have a hum. I have an integrated sound card on my computer, which is connected to my mixer by a 1/8 to RCA cord. Somewhere in there is where the hum is coming from. I’ve tried to separate power from audio cabling as best as I can, and all power is run through an auto voltage regulating battery backup, so there really shouldn’t be any interference there. What else can I do to eliminate the hum?
