Clean Power, Pure Sound...

The first input into any audio or AV system is electricity. It flows through the system, utilised by each component in turn to create the signal that eventually moves the speakers’ drive units or delivers the pixels on-screen. What we see and hear is ultimately fashioned from, and by, mains electricity – it is the ‘raw material’ from which the ‘art’ is created.

The mains supply is distorted by numerous factors as it travels from power stations to be distributed throughout our homes, eroding the performance of high-quality audio and AV systems. As the electronic devices we use proliferate and the demand for electrical power intensifies, the quality of the electricity we feed our systems continues to slide.

The escalation of mains-borne ‘noise’ means that the need for IsoTek’s clean-power technology has never been greater. ‘Differential mode noise’ is especially exacerbated by the switch-mode power supplies that are common in many modern devices, from computers to kitchen appliances. ‘Common mode noise’ is ever-increasing thanks to wireless networking in the home, with mobile phones, wi-fi and Bluetooth bathing us in a sea of airborne interference.

The quality of electricity we feed our audio and AV systems has a profound effect on performance, and that’s where IsoTek’s unique clean-power solutions come in. Without IsoTek, you are only accessing around 80 per cent of your system’s full potential, at best.

Differential Mode

Differential Mode mains noise is created by all electrical appliances – everything with a power supply, in fact. This includes your microwave oven, your television and your computer, as well as every hi-fi component you own.

Common Mode

Common Mode mains noise is often referred to as RFI – transmitted frequencies that surround us but we cannot see. For example, imagine how much data is transmitted by smartphones and tablets; cheap power cables act as aerials for these unwanted frequencies.
