About iFi AUDIO iDefender+

Just imagine experiencing crystal-clear audio without the annoyance of buzz and hum. The iDefender+ USB 3.0 Ground Loop Isolator by iFi Audio, a leader in the audio and music industry, is designed to combat these common audio issues. This innovative device is specifically engineered for those struggling with noisy audio caused by ground loops in their audio chain.

Ground loops occur when multiple plugs within your audio chain create separate earth or ground points, leading to a chain of unwanted noise, distortion, and that pesky buzz. The iDefender+ is a user-friendly solution that effectively breaks this loop, enhancing your audio experience.

When connected to the source device's USB socket, the iDefender+ intelligently detects the presence of a ground loop problem. It then disconnects the computer's earth, eradicating the audible ground-loop hum and lowering the system noise floor. This results in improved resolution and dynamic contrast, giving you the high-quality audio you deserve.

If you're using a USB DAC that relies on USB power from a computer, the iDefender+ offers an additional advantage. When an external power supply is connected to its USB-C socket, it blocks power from the computer and feeds the DAC with clean power from the external supply. This feature significantly enhances the performance of the USB DAC when used with a high-quality, low-noise power adapter like iFi's iPower X.

The iDefender+ is not just reliable, but also durable and built to last. It features upgraded circuitry with low-ESR tantalum capacitors for enhanced input and output filtering. The filtering capacitance has been increased tenfold, ensuring a superior audio experience.

The iDefender+ is compatible with 'SuperSpeed' USB 3.0, which supports a greater amount of audio transfer while maintaining backward compatibility. It also incorporates high-quality gold-plated connectors for optimal signal transfer.

Experience the difference with the iDefender+ USB 3.0 Ground Loop Isolator. It's more than just a device; it's your solution to cleaner, clearer, and more enjoyable audio.
