Spike protection

Our X8 PowerBlocks™ are all fitted with our most sophisticated and powerful MegaClamp™ spike protection. We believe that spike activity on the mains supply can degrade the sound quality from your equipment (they can raise the background noise level in amplification circuits); remove them and in our opinion the sound is cleaner and clearer.

Our MegaClamp™ components were developed for use in the communications industry; we’ve found that they are the most effective way of absorbing spikes affecting your Hi-Fi or Home Cinema.

Connecting to the mains supply

X8 PowerBlocks™ are fitted with a 10A IEC socket which allows you to choose the grade and length of cable you need to connect it to the wall socket. We recommend you opt for either the PowerKord-300™ or PowerKord-500™ for this application.

When choosing your mains cable, make sure you select the version with the 10A IEC connector. Click here to view PowerKords™.
