GND Defender
SKU: 03-06-042-0001-00
Key Features
Intelligent Detection
With a GND Defender at the IEC power input, it will intelligently detect and remove the ground loop at the component.
EMI Shielding
The GND Defender device safely retains its EMI shielding.
Global Usage
The GND Defender can be used all over the globe.
Battleship build.
The GND Defender is not only at the cutting-edge in terms of technology but also safety:
- High-performance glass passivated semiconductor
- High Case Dielectric Strength of 1500VRMS UL Listed
- X7R Capacitor
Intelligent ground detection.
The GND Defender:
- Intelligently breaks DC ground loops to eliminate ground loop hum
- EMI shielding is retained
- Equipment Safety is unaffected (not a ground lift – so maintains equipment safety ground)
If multiple ground loops exist, more than one GND Defender may be required. The GND Defender is smarter than the average ground lift. By a long way.
How do I use?
GND Defender
Insert the GND Defender into the device and the connect the external device into the GND Defender.

Frequently Asked Questions
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, that often lead to audible hum on your speakers.
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 and/or buzz. By isolating one of the grounds you may reduce the amount of hum in the system.
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 noise.
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.
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. It forms when there is more than one path for the audio ground or shield signal to flow through. For example, if a system consists of a preamplifier and power amplifier connected by RCA interconnects, and both the power amp and preamp are earthed to the mains, there are two paths for the ground signal to flow. One through the shield and return wire in the interconnect, and the other via the mains earth in the power board or house wiring and the two equipment earth wires.
Here is where the GND Defender can be of assistance. By inserting it into the earth system of the second (or more) low-resistance earthed component, you may reduce the effect of the earth loop, evidenced by a reduction in hum or buzz
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.
If anything, our Ground Defender will improve a connected component’s sound quality past eliminating a ground loop.
