The iFi iDefender Max is a highly advanced USB adapter specifically designed to detect and eliminate ground loops in audio devices. This technology significantly enhances the clarity and quality of the audio signal, especially when a computer is used as the audio source. The iDefender Max separates the noisy USB power supply from the computer and replaces it with a clean external power supply via a USB-C connection, resulting in noticeably better sound quality.

A standout feature of the iDefender Max is its ability to automatically detect and interrupt ground loops without compromising device safety. This effectively prevents hum that can arise from different ground potentials. Additionally, the adapter provides an external power supply through a USB-C port, offering a clean and stable power source for improved audio performance.

The iDefender Max supports USB 3.0 for fast data transfer and is backward compatible with USB 2.0, allowing it to support a wide range of devices and enabling lag-free playback of high-resolution audio files. The housing of the iDefender Max is made of aluminum, which not only ensures a long lifespan but also acts as a heat sink to improve heat dissipation. Furthermore, the housing provides complete protection against electromagnetic interference (EMI), further optimizing audio quality.

With a power output of up to 100W (20V/5A), the iDefender Max is versatile and can be used with a variety of devices, including USB DACs, audio interfaces, USB microphones, and USB speakers. The iFi iDefender Max is the solution for audiophiles seeking interference-free audio playback.
