## Overview

The Pureformer Stereo Isolation Transformer delivers a pristine audio experience with a frequency response of 20Hz to 20kHz and a 600-ohm impedance, all housed in a durable diecast aluminum construction. Perfect for professionals looking to enhance their sound quality.

## Description

The Jk Audio Pureformer Stereo Isolation Transformer provides hum and noise reduction for sound cards and audio equipment and removes ground loops and DC paths that can cause hum and signal breakup. The Pureformer isolates the electrical grounds of two pieces of audio equipment. This is especially important in the case of computer audio cards connected to high quality/low noise audio equipment. The computer electrical ground is often filled with noise from disk drive activity and data transmission. Many audio cards use the same electrical ground for the computer and the audio signal. When the computer audio card is connected to your studio equipment, the electrical noise from the computer can leak into the rest of your audio system. The Pureformer completely isolates the electrical ground of the two systems and only allows audio signals to pass through. Pureformer cannot remove noise once it has been mixed with the audio signal, so it is important to find and treat the source of each problem.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fanstastic little gadget!
  

*by M***N on Reviewed in the United States on February 25, 2014*

In my living room I have a PS3 console hooked up to a mixer which is then hooked up to some powered monitors. This way I can watch Netflix streaming and DVD's/Blu-ray discs with a nice loud sound as our HDTV has fairly weak speakers. Although the sound is magnificent I was always bothered by this buzzing noise that came out of the speakers and was present throughout the movies. I tried using the more expensive surge protectors in hopes that the noise would disappear or at least be less obvious, but it did not work. Doing a little bit of Googling I learned others had the same issue with the buzzing sound. I took a chance and ordered this gadget. Now it is not the cheapest thing on the market, but some of the cheaper solutions had mixed reviews. I can now state that I am very glad that I took a chance, because I hooked this gadget up and the buzzing noise is completely GONE! It is so quiet that when nothing is playing it seems as if I didn't even turn on the monitors. Hook-up is ridiculously easy as you plug in the source of the sound into the "IN" side (left) and plug in the output of the sound into the "OUT" side (right). Now I can enjoy a nice rich sound with my movies. Highly recommended.

    Not usable
  

*by K***H on Reviewed in the United States on February 11, 2015*

I used several of these to isolate the ground on laptop audio outputs (mostly Mac PowerBooks) from the ground on the video outputs (routed to projectors, usually adapting to VGA on the way).  This combination frequently produces ground-loop hum, even when that systems are properly set up and grounded.  These transformers cannot handle the laptop audio outputs if they are turned up all the way and the signal is pretty hot.  Mostly, they just distort under these conditions, but I recently had one self-destruct (internally) and just turn into a permanent distortion generator--completely unusable.  I'm now shopping for an alternative brand which can actually handle the use I need them for.

Did not fix my ground loop problem, I used on my RCA cable to my sub woofer and did not do the job.
