Does anyone have experience with noise reduction ?

Category: Accessories

I live part time off the grid. My power source is from a 800 Ah battery bank 48 v. converted to 120v true sine wave with a Trace 4048.I tried an Audio Magic Stealth filter without success. The buzz in the line creates a constantly noisey background that dosen't cause fatigue but can be irritating if one dwells on it.Any suggestions? This is a common problem and is not RFI.Thanks

I agree that the source of the noise is the inverter. And it's very hard to get rid of noise that comes from the source of the electrical power itself. I think the most direct way to kill it would be to use a balanced power unit such as Equi-Tech, ExactPower, or Balanced Power Technologies. Basically, they'll divide the single 120V 60~ into two 60V 60~ which are 180 deg. out of phase and
thus null out any line-bourne noise. Read up on it at any of their websites.
