IFI AUDIO IDEFENDER+ Anti Ground Loop Filter Male USB-A to Female USB-A

The iFi Audio iDefender+ allows you to cancel noise originating from a ground loop in your audio system. Indeed, the inevitable use of several plugs and cables within your HiFi installation implies the presence of several ground points, which can cause ground loop problems and therefore interference, distortion and noise. The iDefender+ is therefore an effective bulwark against this problem.

iFi Audio iDefender+

Anti Ground Loop Filter Male USB-A to Female USB-A

iFi Audio iDefender+ Filtre Anti Boucle de Masse USB-A Femelle vers USB-A Mâle

The iFi Audio iDefender+ allows you to cancel noise originating from a ground loop in your audio system. Indeed, the inevitable use of several plugs and cables within your HiFi installation implies the presence of several ground points, which can cause ground loop problems and therefore interference, distortion and noise. The iDefender+ is therefore an effective bulwark against this problem.

Its simple but formidable operation allows it to automatically detect the presence of a ground loop once connected to a USB source such as a computer. It breaks this ground loop by disconnecting the ground from the computer, while removing the noise generated, lowering the background noise and improving sound definition and dynamics.

In this version, the iDefender+ has a female USB-A input, a male USB-A output, as well as an additional USB-C port for connecting an external power supply (optional and sold separately) when used with a USB DAC.

Use with USB DAC

If you use the iDefender+ with a USB DAC powered from a computer, rather than from an AC adapter or built-in battery, then the iFi Audio system offers an additional advantage. If an external power supply is connected to the USB-C jack on the side of the iDefender+, then the iDefender+ will block power from your computer to provide your DAC with a clean electrical signal from the external power supply. Thus, it is possible to combine the iDefender+ with a high-quality, low-noise external power supply to maximize the performance of your USB DAC.

Efficient improvements for ever less noise

The iDefender+ is a direct enhancement of the iDefender 3.0, taking advantage of a redesigned circuit that now incorporates low ESR tantalum capacitors for 10 times the filtering capacity.

IsoEarth

IsoEarth technology breaks ground loops to eliminate feed noise, reducing background noise while improving dynamics and musicality.

External power supply

It is possible to inject a 5V DC power supply via an external low-noise power supply, using the USB-C port on the side. This allows the USB power supply from the PC to be blocked and replaced by a power supply providing a clean signal. This is also an excellent way to break ground loops on a USB-powered DAC.

USB 3.0 SuperSpeed

The USB 3.0 SuperSpeed standard allows faster transfer of audio data, while remaining backward compatible with previous standards. The iDefender+ is equipped with gold-plated connectors for excellent conductivity and resistance to oxidation.

Great device!
I have a Chinese DAC that is powered by USB, but there is no noise filtering from the current, so I needed to feed it with clean electrical signal. Ifi Defender+ does a perfect job for this - I'm using a smartphone power supply now, but I'm thinking of buying an Allo Nirvana to further improve the sound quality.
