Rated 4.7 out of 5 by 6reviewers.
Rated 3 out of 5 by removes speaker hum, but adds transformer hum This worked great at removing 60hz hum from my subwoofer, sadly the transformer vibrates so hard that its 60hz hum is almost as loud. October 13, 2016
Rated 5 out of 5 by Excellent product! The Isolator Series 120V 1000W Isolation Transformer is an excellent product. It is perfect for my needs (with a couple of my own warranty nullifying modifications). Its workmanship is world class and its components are top notch. March 22, 2016
Rated 5 out of 5 by Awesome ioslation xfmr This Tipp-lite isolation transformer is an excellently made item. It is well built and thoughtfully designed. February 24, 2016
Rated 5 out of 5 by Good quality, solved the targeted problem I used this to float my audio system, I live in an old neighborhood with several amps of mysterious ground current that are caused presumably by a high-resistance neutral from the homes of one of my neighbors. the current caused buzzing noise on my audio system. With the IS1000, my system is completely quiet. Build quality is good, mine has a toroid transformer and beefy outlets. Makes no audible noise in my install. October 14, 2014
Rated 5 out of 5 by The IS1000 is quiet & reliable I needed power isolation for a sensitive equipment installation & after searching the Web I came across Tripp Lite products. So I did some research & decided to give the IS1000 a try & after a year of continuous service I know I made the right decision. This unit function's flawlessly, is quiet, built like a tank, is cost effective & has an impressive design. September 6, 2013
Rated 5 out of 5 by Clean Energy! I use this isolation transformer wit my amateur radio equipment. The device provides clean 110 volt power to my power supplies. September 5, 2013
