NeoPlug builds upon IsoPlug’s performance by utilising an innovative circuit that overcomes capacitor inductance allowing it to react quickly to transient and high frequency mains noise.

  • Removes Common Mode and Differential Mode mains noise.
  • Shunts mains noise away from your sensitive audio components.
  • Second stage auxiliary circuit reacts quickly to high frequency mains noise.
  • Can be deployed next to mains noise creating devices.
  • Useful and cost effective way to upgrade a standard mains distribution block.
  • 8,000A of instantaneous protection.
  • Available in UK, EU and US versions.


The NeoPlug is the next step on from the IsoPlug, developed as an intellectual exercise to overcome capacitor inductance and produce a device that works consistently at optimum levels and reacts quickly to transient noise. The NeoPlug has an additional circuit to the IsoPlug, which reacts at lightening fast speed – critical for the effective removal of high frequency mains noise.

The NeoPlug can also be used in many ways, one option is to plug it into a typical ‘off-the-shelf’ distribution strip to give added performance. This forms a very cost effective way of giving a good level of mains filtering whilst distributing power. Plug two NeoPlug’s into this strip to separate digital and analogue components. You can also deploy NeoPlug around your home next to noisy appliances.

The NeoPlug features two highly effective circuits that work together and synergise to create a result far greater than the sum of the parts. In sonic terms the NeoPlug has a way of making the music more involving to listen to. The midrange, where the ear is more sensitive, is extremely open with an increased realism in terms of imaging. The big difference between NeoPlug and other similar products on the market is it’s ability to effectively remove high frequency mush, that typical digital sound which can all to easily cause listening fatigue, it is in this area that the auxiliary circuit really comes into its own.

We live today in an environment where the majority of appliances that draw power, corrupt the mains electricity supply (for example computers, fridge freezers, TVs, etc.) The result is a heavily distorted waveform and this is not good for audio equipment. The irony is that many audio products and often the best ones produce a lot of noise themselves. Without doubt, the best way to attenuate this noise is as close as possible to the source. The GII NeoPlug will solve this problem.

Simply plug the NeoPlug into any wall socket as close as possible to any domestic appliance that produces, or is suspected of producing noise. This will prevent it from polluting the mains in the rest of your home. Use the NeoPlug to eliminate mains noise so that your Hi-Fi or A/V system can perform at its best. More than one NeoPlug can be used to reduce mains noise further. For best results start with the socket next to your system, and then position additional NeoPlugs near noisy appliances, fridge freezer, computers, etc. There is no harm in experimentation. Although the NeoPlug works brilliantly on its own further benefits can be achieved when more than one are used together. Make sure your plug socket switch is in the on position.
