AMR equipment already includes ground lift circuitry internally so there isn’t any further benefit in using this GND Defender with them.

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…

You don’t, it’s a passive component that does its job upon connecting it right in-between a power cable and audio product powered by it.

Plug the GND Defender into the IEC socket of your earthed component, then plug the IEC power cable into the GND Defender.

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.…

That’s correct, our Ground Defender works only with products and power cables based on the IEC standard.

Yes, our GND Defender is safe to use as it is a fireproof product.

The core operation principle of our Ground Defender is the same, but this one was designed to work with AC line.

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…

Our Groundhog+ also eliminates ground loops, but via a set of connectors different that our GND Defender’s IEC interface.
