SilentPower GND Defender

SilentPower GND Defender — Ground Loop Elimination

Unpleasant low-frequency hum or hum from speakers can be caused by ground loops in audio systems that have multiple grounds. SilentPower GND Defender is a solution that intelligently detects and interrupts ground loops at the component level to eliminate interference without compromising safety or EMI shielding. With worldwide voltage support of 90-240V and continuous current of 7A, it is ideal for a wide range of devices. This product stands out for its robust construction and ability to maintain system integrity.

Intelligent Ground Loop Elimination

SilentPower GND Defender uses AI Ground Detection to quickly and effectively recognize ground loops on a component. Unlike conventional "ground lift" solutions that can compromise safety or shielding, GND Defender:

• Disconnects DC ground loops, eliminating hum.
• Maintains EMI shielding, meaning that sensitive signals are not disturbed.
• Does not violate safety standards, as it is not a classic "earth lift".

If there are multiple ground loops in the system, it may be necessary to use multiple GND Defender units.

Robust and safe construction

Designed like a "battleship", GND Defender is equipped with technologies and materials that guarantee high reliability:

• X7R capacitor for stability even at high temperatures.
• Flame-resistant IEC socket and chassis, made of fire-resistant polymers with a UL94-V0 classification.
• Ability to handle surge peaks up to 220 A, protecting connected devices from damage.

These features make the device ideal for both professional and home audio systems.

Technical data

• Voltage: 90-240 V, compatible with all world standards.
• Maximum power rating: >10 A.
• Continuous current rating: 7 A.
• Surge protection: 220 A.

Practical recommendation

Although GND Defender effectively solves ground loops, it remains a good practice to maintain at least one direct power cable ground in the system.

SilentPower GND Defender is the ideal choice for those looking for a smart and safe solution to optimize audio performance without compromise.
