Since 2001 Isotek have dedicated their research towards mains conditioning products to maximise audio and video performance in the home. Customers whose homes are in built up areas or close to industrial areas may benefit from an Isotek most of all, as these mains currents often contain spikes, noise and distortion which can seriously take the edge off your hifi's sound quality.

If you have mains generated noise on your home ring main from a household appliance like a fridge or microwave oven, the Isotek Isoplug will massively reduce it's effects on your audio system so that music becomes much more expressive and musical.

You can add further Isotek Isoplug's to your home to improve noise reduction even further. Start by adding the first Isotek Isoplug in a mains socket near to your system, then add them into mains sockets closest to noisy appliances.

A cost effective, first line defence against mains noise pollution of your hifi system.
