iFi Audio iDefender+ USB C – USB A

Is the sound of your audio system affected by noise, hissing, buzzing, or humming? The iDefender+ from iFi Audio is designed for anyone struggling with audio signal disturbances caused by unwanted ground loops in the audio chain. Using multiple plugs in your audio setup means separate grounding points. These multiple grounding points create a ground loop problem, leading to unwanted noise.

Here’s the solution: When the iDefender+ is plugged into the USB port of the source device, it detects whether a ground loop issue is present. The iDefender+ interrupts the ground loop by intelligently disconnecting the grounding of the computer. It not only eliminates the audible hum of the ground loop but also reduces the system's background noise and enhances the sound resolution and dynamic contrast.

Are you using the iDefender+ with a DAC powered via USB from the computer rather than from the mains or an internal battery? Good news: the iDefender+ offers an additional benefit. When an external power supply is plugged into the USB-C port on the side of the iDefender+, it blocks power from the computer and instead supplies the DAC with clean power from the external power source. When using a high-quality, low-noise power supply like the iPower X or iPower Elite from iFi Audio, the audio performance of the USB DAC significantly improves.

Thanks to the iDefender+, you can enjoy a markedly improved sound quality as all disruptive noises such as buzzing, hissing, humming, and noise are eliminated. Additionally, the iDefender+ also enhances the stability of the USB signal, helping the DAC or amplifier reproduce the signal more cleanly and accurately. It is compact and lightweight, making it easy to integrate into any audio system.
