overview

Fit our best spike clamps

The MegaClamp Ultra is a plug-in device designed to improve the sound of your Hi-Fi or Home Cinema by reducing the effects of mains voltage spikes. MegaClamp Ultra is the most sophisticated model in the 'MegaClamp' family and offers the best performance of all of our spike-clamping products.

MegaClamps use components culled from the communications industry which are more effective at absorbing mains spike activity than anything we have tested before. MegaClamp Ultra contains multiple MegaClamps and also employs a component that reduces spike activity on the earth. The MegaClamp Ultra is mounted in a 'wall-wart' type box which simply needs to be plugged into a power socket close to your Hi-Fi system. A spare socket in your mains extension is ideal.

It doesn't need to be replaced

Unlike the SuperClamp which wears out and becomes less effective over time, the MegaClamp is many times more effective than the SuperClamp and has the advantage of not needing to be replaced every five years. As with all of our clamping products, we recommend that you unplug your Hi-Fi or Home Cinema equipment in the event of a storm - nothing will protect your equipment in the event of a direct lightning strike. Not compatible with Balanced Mains

  • What are spikes?

    A spike is a very brief over-voltage 'event' ranging from a few tens of volts above the highest legal peak voltage (360V for 230V), up to several thousand volts. They are typically under 1 millisecond in duration, are very common and often (though not always) the energy involved is small. Longer duration events are called surges and have the potential to do more damage, but mercifully these are less common.

    Spikes are caused by things such as lightning strikes, power outages, tripped circuit breakers, fluorescent lights, refrigerators and washing machines switching on and off. The quality and severity of spike activity varies during the day, and from day to day. Even with well-designed equipment, spikes or transients – if regular – can and will prematurely stress and wear out critical mains-connected parts and their insulation.

    In our opinion, high voltage spikes can also cause audible degradation of Hi-Fi sound by their effect on a Hi-Fi system's power supply and by raising the background noise level in amplification circuits. The spikes saturate the core of the mains transformer, preventing normal transformer operation during the period of each spike and causing distortion to the waveform. Mains spikes reduce the capacity of the power supply by 'strangling' the transformer operation producing subjective effects on an amplifier like softened bass and increased high frequency distortion.

    "Highly Effective Clamp."
    I have purchased 2 of these little diamonds and find them to be highly effective, as I have had my fair share of bleeps, crackles, spikes and other mains borne rubbish finding it's way through to my loudspeakers!
    The beauty of this Megaclamp Ultra, is that it's effectiveness lasts for for life, as they are made using top quality components, unlike the cheaper 'Silencer' or 'Superclamp' which will probably need rebuilding, or replacing after 5 years or so - you only get what you pay for is a well worn maxim that I am not about to abandon now!
    A simple looking plug-in device maybe, but I am well pleased with the damping effect that they have on my hi-fi system. I have 2 Powerbars plugged into the mains supply, and have a Megaclamp Ultra plugged into each one of those, the results are a cleaner sounding music system, and any spikes have been squeezed and filtered away from the business end - the loudspeakers!
    Highly Recommended!
