iFi audio iDefender+ Protect against Ground Loop Noise & Noisy USB power
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.
Features:
- Kills USB power noise by ‘breaking’ the earth/ground loops in the correct way.
- Inject 5 volts of clean power clean via the ‘separate’ micro 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 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. The units incorporate high-quality gold-plated connectors for optimal signal transfer.

Manufacture Description
Break the loop
When 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?
Are 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.
New and improved.
We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.
The iDefender+ now comes in 3 versions and includes the newer USB-C connector.
