iFi Audio GND Defender - Ground Noise Defender for HiFi & Audiophile Systems | Reduce Hum & Buzz in Home Theater, Studio, and Car Audio Setups

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 both safety and EMI shielding (e.g. cheater plug), or EMI shielding.

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

AI ground detection
Deploy GND Defender at the IEC power input to intelligently detect and remove ground loops at the component to eliminate unwanted ground loop hum. EMI shielding is retained and equipment safety is unaffected. More than one GND Defender maybe required if multiple ground loops exist.

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
• High-temperature stability
• Flame resistant IEC socket/connector/chassis
• Fireproof polymers UL94-V0

Remember that best practice is to always keep at least one direct power cable connection.
