Accessories specialist Russ Andrews has announced two new mains noise-reducing products with the Mains Zapperator and MiniZaps.
Following the release of the Speaker Zapperator last year both of the new products are designed to remove RF (radio frequency) and EMI (electro magnetic interference) spikes from the mains power supply by absorbing them.
Andrews claims the spikes are often caused by mobile phone and wireless networks, both of which are becoming more common in the home.
The Mains Zapperator is intended for use in homes with wireless networks or ethernet-over-mains Homeplugs. It simply plugs straight into a wall socket near the hi-fi or AV system, or wireless router, and creates a ‘quiet zone’ without the potential interference.
There are two types of MiniZaps. One is tiny and fits into Kimber analogue interconnect cables for use with line and phono level signals, the other is built into blanking plugs (phono, DIN or XLR format) that plug directly into unused sockets on the amplifier or source components.
Russ Andrews said: “Working at RF and super high frequencies, the Zapperator has the effect of reducing the impact of these spikes on the audio bandwidth without affecting the audio frequencies themselves. I was shocked by the level of deterioration in sound quality whenever I had my computer switched on near the hi-fi system. This led me to investigate the effects of RF and EMI on audio signals and working with (mains experts) Ben Duncan and Paul Houlden, we developed the idea for the Zapperator to help combat this degradation.”
The Mains Zapperator is on sale now for £85, the Mini Zaps start at £139.
