Galvanic isolator transformer for stereo audio signals, RCA inputs and outputs

Hearing weird humms in your audio systems? There is a good chance you have something called ground loop problem. This means that your audio signal ground leads carry a small current between devices. This small current generates magnetic field and induces this small interfering signal into your audio signal, which can be heard in many cases as some sort of a humm, buzz or some other weird noise. Occasionally these weird sounding noises can originate from audio source itself or it's power supply... And no, listening to Justin Bieber is considered as noise, but this device will not help you with this issue.

Audio isolator transformer helps the problem by breaking the galvanic path between the two devices. Galvanic means a path made by electricity conducting conductor. This unit has internal transformer for both channels and this signal transformer has equivalent number of windings on primary and secondary side. This way the the signal is converted from electric to magnetic and back to electric, therefore breaking the galvanic path.
