If you’ll hear audible hum on your speakers or headphones, this is due to a ground loop in your setup and our Ground Defender was designed to eliminate this unpleasant…
Sound systems can range in scale from being simple to very extensive. Generally the more components that are earthed in the system, the more likely an earth loop will develop.…
To maintain earthing safety for connected equipment a maximum of 1.2V is allowed to develop across the 100 ohm resistance in the GND Defender, with excess current being passed through…
Ideally you should use one Ground Defender per audio component, but also you should remember to connect at least one such product to your power bar/conditioner directly.
The GND Defender won’t be of benefit to an unearthed system (where all the components have double insulated 2 pin power supplies). Instead, it will probably help if the system…
Although these words sound similar, here we are using ‘earth’ to mean the mains earth, and ‘ground’ to mean the audio zero volt (0V) line on your equipment.
It aims to reduce the effect of ground loops in a system. If more than one audio device in your system is earthed to the mains, you may experience hum…
The GND Defender is a ground lift device. It inserts resistance between the mains earth and your equipment ground. It is meant to eliminate ground loops in your audio setup,…
