Balanced Power, by Larry Deniston

Balanced Transformers for Power Conditioning

There are many ways to address the quality of power feeding our equipment.  One of our members, Fred S., brought up the idea of balanced power as a solution for cleaning up power.  This was a new concept to me, but the more I looked into it, the more sense it made.  The following is an excerpt from Toroid Transformers:

Balanced Power Transformers are designed with a center-tapped secondary winding which consists of two identical, mirrored secondary windings in series and an electrostatic shield. When the center tap is grounded, these two identical windings short circuit the equal amplitude but opposite phased noise current and greatly attenuate (low to medium frequency) common mode noise. The ground noise amplitude goes to zero, which eliminates audio to be free of noise interference.

There is also quite a bit of more in-depth information on the Equi=Tech website.   The following figure is from the Equi=Tech site:

Check it out, I have a balanced power transformer in my set up and it’s made a world of difference in the sound quality.

  1. I have a pair of Equi=Tech’s, one upstairs and one in the media room. They do work very well at taming some wildly funky power that is delivered to my home by the City of Ashland.
    I third, Larry & Fred’s recommendations.
