Lab Test Results from Cal Tech's Ligo Observatory -- As Balanced Power moves beyond the world of professional audio and video production, various other high tech industries where power quality is of extreme importance have reported their findings with clinical testing of Equi=Tech's balanced power products in various venues where they've been applied.  This is a report from one of the top scientific research facilities in the country.  Here is a link to the Cal Tech / MIT Ligo observatory website.

Equi=Tech Model 2Q and Model Q650 Product Review -- A product review of the Model 2RQ and the Model Q650 (replaced by Model 1RQ) that first appeared in Stereophile magazine.  (The review begins about 1/2 way down the page.)
.
"Balanced Power from Equi=Tech" -- A Revolutionary Concept and Newly Adopted Standard in AC Power Distibution.  An article published on the subject of balanced power by Equi=Tech's founder and President, Martin Glasband.  This one is written especially for the layman who may not be familiar with much engineering terminology.  Published in the August, 2001 issue of Wide Screen Review magazine, this paper provides the reader with the simplest explanation of balanced power technology that we know of.

"Lifting the Grounding Enigma" -- A landmark article first published in the November, 1994 edition of Mix Magazine that represents a breakthrough in power technology as it specifically applies to the quality and accuracy of sensitive electronic equipment with respect to performance specifications. This writing offers a simple explanation for grounding noise and interference in the most sensitive of all electronic signal circuits. It further goes on to describe from a historical perspective how electrical industry standards have led to a "noise crisis" and offers an elegant, common sense solution to the problem.   (en Español)

"Balanced Power: The Next Generation" -- A technially in depth writing about balanced AC power in theory and application by Martin Glasband that appeared in Live Sound! International Magazine. Is balanced power just patch or is it better understood as a foundation for sensitive electronics systems? The article provides clear description of AC power issues as they impact sensitive equipment performance in both digital and analog systems.
.
"The Origin of Balanced Power" --  Here's another recent paper written by Martin Glasband on the subject of balanced AC.  This article, published in the September 1997 issue of S&VC Magazine, is both anecdotal and informative, giving the reader some interesting background on the discovery of balanced AC, also going into some depth and detail on how "dirty power" affects both digital and analog signal processing.
.
"An Overview of AC Power and Noise" -- A condensed introductory piece on the subject of electrical noise and power. This article briefly covers the ways that AC noise manifests, the subject of power quality in general, non-linear reactive loads, objectionable grounding currents and moreover how balanced AC addresses these issues.
.
"Equi=Tech Symmetrical Power System" -- A review of Equi=Tech's Model ET1.5R by Roger Nichols that was published in EQ Magazine.
.
"Equi=Tech ET2R Symmetrical Power System" -- A field test of an Equi=Tech Model ET2R by Mark Frink that appeared in the June 1997 Issue of MIX Magazine.  It is interesting to note that field testing of Equi=Tech's balanced power gear was performed with the intent of demonstrating the effectiveness of balanced AC as it applies to digitally based signal processing equipment.  The results are both verifiable and quite astonishing, especially when one considers that a "state-of-the-art" Neutrik A2D test set was used in this field test. 
.
"Power Management in the Studio" -- Roger Nichols' background in Electrical Engineering is demonstrated here in this popular reprint article from the July 1996 issue of EQ Magazine. Roger discusses power quality issues, ac power distortion and how these factors affect electronics, particularly in recording studios. Roger's legacy will continue to provide a higher quality of life for many millions of people for centuries to come. RIP Roger. 
.
"Audio Noise and AC Systems" -- The first of two articles published in Recording Engineering and Production Magazine (REP) in the early '90s written by Martin Glasband, the President of Equi=Tech Corporation. These articles were among the first on the subject of balanced AC power ever to appear in print in any professional publication.
.
"Audio Noise and AC Systems Revisited" -- Here's the second of the REP articles written by Martin Glasband which launched balanced AC into the world of professional audio and video.
