iFi audio SilentPower iDefender MAX USB filter
The SilentPower iDefender Max is an intelligent USB-C ground loop breaker designed to eliminate distracting hum and buzz from computer-based audio setups. It intelligently removes unwanted earth connections using IsoGround® Technology, then automatically restores grounding if a current-related fault is detected — keeping your gear safe. USB Noise Termination® cleans up noise riding on USB power at the source, while a dedicated external USB-C input lets you bypass noisy PC power with a cleaner supply. Compact at just 21 g, it supports up to 100W (20V/5A) and USB 3.0 for stable high-resolution playback.
- Eliminates ground loop hum and buzz in USB-C computer audio setups
- IsoGround® Technology removes the earth connection while preserving safety
- USB Noise Termination® reduces noise from USB power right at the input
- Supports up to 100W (20V/5A) passthrough and USB 3.0 (backward compatible with USB 2.0)
Eliminate USB-C Ground Loop Hum
The SilentPower iDefender Max is an intelligent USB-C ground loop breaker that silences the low-frequency hum and buzz that creeps into computer-based audio when multiple devices share different ground paths. Place it inline between your computer and your USB DAC, headphone amplifier, or powered speakers, and unwanted earth connections are intelligently removed. IsoGround® Technology handles the lift while a built-in safety function automatically reestablishes the earth connection if a current-related fault is detected — so equipment and user safety stay intact.
Cleaner Power, Broader Compatibility
USB Noise Termination® tackles noise riding on USB power at the input, and a dedicated external USB-C power input lets you bypass the computer's USB bus for a cleaner audiophile-grade supply. With USB 3.0 support and up to 100W (20V/5A) passthrough, the iDefender Max fits comfortably into broader USB-C setups while keeping high-resolution playback stable.
