The optimum configuration for each system is one ground/earth for the entire system. If a system has multiple grounds, unwanted ground loops are often created. These systems will then have an annoying low frequency hum (emitted by the loudspeakers).
Current solutions compromise either (i) both safety and EMI shielding (e.g., the cheater plug), or (ii) EMI shielding. And most are single country (US) uses only.
The GND Defender in the right way, intelligently detects a ground loop and will cut the ground for that component.
With a GND Defender on the IEC power input, it will intelligently detect and eliminate the ground loop in the component.
Behind this, the GND Defender:
If there are several ground loops, more than one GND Defender may be necessary.
The GND Defender is smarter than the average grounding device. By far.
The GND Defender is not only state-of-the-art in terms of technology, but also in terms of safety:
Remember that the best practice is to always maintain at least one direct power cable connection.
220A overload capacity. With a maximum rating >10A, 7A DC rating, handles all voltages worldwide from 90-240V.
Intelligently blocks DC mains voltages to eliminate transformer hum. Equipment safety is not affected.
EMI shielding is maintained.
