IsoTek’s range of Syncro named products, can remove irritating transformer hum from your equipment and improve sound replay. Strictly speaking the problem with DC on the mains as it is referred to, is an imbalance of the mains sine wave on the zero volts line, it isn’t really a mains noise, but it can cause considerable mechanical vibration within products which will dramatically affect performance.

It is the strangest of problems on the AC line, which is a quirk of magnetic circuit design. A simple hairdryer, as well as solar panels, fast charging stations for electric cars, can cause massive noise in big amplifier transformers. IsoTek has developed a series of devices called Syncro that remove the DC offset and dramatically improve your audio, audio-video or network performance.
