SilentPower GND Defender
The SilentPower GND Defender hunts down and disconnects the unwanted ground loops that cause low-frequency hum and buzz in a system — without compromising your equipment's EMI shielding or safety.
Smart, safe grounding
It intelligently detects ground loops and disconnects them automatically, re-instates the ground if a fault is ever detected, and works across mains voltages worldwide (90–240V).
