Ground control to Major components.

The optimum configuration for each system is one Ground/Earth for the whole system. If a system has multiple Grounds/Earths then it often creates unwanted ground loops. These systems will then have an annoying low-frequency hum (emitted from the speakers).

Current solutions either jeopardise (i) both safety and EMI shielding (e.g. cheater plug) or (ii) EMI shielding. And most are single country (US) uses only.

The GND Defender in the correct way intelligently detects a ground loop and will cut the ground for that component.

AI ground detection.

With a GND Defender at the IEC power input it will intelligently detect and remove the ground loop at the component.

Behind this 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.
