Protect Against Ground Loop Noise
iFI Audio - iDefender+

iFI Audio - iDefender+

Is your audio still taking a beating from buzz and hum? Is your audio still plagued by hum and buzz? Using multiple plugs within your audio chain means separate earth/ground points. These multiple earth or ground points cause a ground loop problem. This creates an unwanted chain of noise, buzz and distortion.

Struggle no more. iFi’s iDefender+ provides the simple, effective solution you need.

Break the loopWhen plugged into the source device’s USB socket, the iDefender+ detects whether there is a ground loop problem. It breaks the ground loop by ‘intelligently’ disconnecting the computer’s earth and, as well as eradicating audible ground-loop hum, it lowers the system noise floor, improving resolution and dynamic contrast.

Using a USB DAC?


greater performanceAre you using the iDefender+ with a DAC that relies on USB power from a computer rather than power from the mains or a built-in battery?

Good news. The iDefender+ offers an additional benefit. If an external power supply is plugged into the USB-C socket on its side, it blocks power from the computer and instead feeds the DAC with ‘clean’ power from the external supply.

If a high-quality, low-noise power adapter such as iFi’s iPower X is used, the performance of the USB DAC will be significantly improved.

Premium iFi Features


Kills USB power noise by ‘breaking’ the earth/ground loops in the correct way. It significantly reduces the system noise floor and makes for better dynamic contrast, warmth and resolution.


Inject 5 volts of clean power via the ‘separate’ USB-C port. This disconnects the USB power from the PC and replaces it with clean external power. For ultra-low noise, use our 5-volt iPower Elite or iPOWER X.


‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible.
