iDefender Max

The SilentPower iDefender Max by iFi Audio is an advanced, intelligent USB-C ground loop breaker designed to completely eliminate distracting hum, buzzing, and noise from your computer-based audio setup. This essential audio accessory removes the common issue of ground loop noise, which can be introduced by using multiple plugs and excess earth connections within your audio system. With the iDefender Max, you can experience uninterrupted, crystal-clear audio that allows you to fully immerse yourself in your favorite music, movies, and games.

IsoGround® Technology – Safety Meets High-Performance Audio

Equipped with IsoGround® Technology, the iDefender Max intelligently removes unwanted earth connections without compromising safety or performance. This ground loop isolation ensures that any hum or interference caused by ground loops is eliminated, offering you a clearer, more precise listening experience. By isolating the ground connection, this technology enhances the purity of your sound, making it the ideal solution for high-end audio enthusiasts who demand the best from their equipment.

USB Noise Termination® – Remove USB Power Noise for Pristine Sound Quality

The USB Noise Termination® feature in the iDefender Max targets and eliminates noise generated by USB power sources at the point of origin. This intelligent noise filtration removes unwanted interference, distortion, and electrical noise that can detract from your audio experience, ensuring that your system delivers only clean, high-quality sound. Whether you're using USB DACs or other audio devices, the iDefender Max ensures your sound is free from electrical interference.

External USB-C Power Input for Enhanced Audio System Performance

To further elevate your audio system, the iDefender Max includes an external USB-C power input that allows you to bypass noisy USB power coming from your PC. By connecting a high-quality, clean external power supply like the iFi iPower2, you can further reduce noise and interference. The iPower2 power supply is an ultra-quiet, audiophile-grade solution, featuring iFi's proprietary Active Noise Cancellation II technology to eliminate any remaining noise. This results in more than 10 times quieter performance compared to typical power supplies, ensuring a significant boost in sound quality and clarity.

Safety-First Ground Loop Elimination – Protect Your Audio Equipment

The iDefender Max doesn’t just eliminate ground loops – it ensures the safety of your valuable audio equipment as well. Many ground loop breakers compromise the safety of your gear, but the iDefender Max automatically reestablishes the earth connection whenever a current-related fault is detected, such as from a short circuit or power surge. Excess current is safely directed to the earth instead of reaching your connected devices, preventing damage and ensuring that your equipment remains protected during unexpected electrical events.

Perfect Pairing – Maximum Compatibility and Power Support

The iDefender Max supports power inputs of up to 100W (20V/5A), making it compatible with a broad range of devices, including high-powered audio systems, USB DACs, and even larger equipment. Whether you're using it with a USB DAC to stream high-resolution audio files or connecting it to a desktop audio setup, the iDefender Max ensures that your system is powered by clean, filtered electricity. Plus, with USB 3.0 compatibility and backwards compatibility with USB 2.0, you can enjoy high-speed data transfers without compromising on performance.

Unleash the Full Potential of Your Audio System with the iDefender Max

The iDefender Max goes beyond ground loop isolation. Its intelligent design, superior power support, and ability to completely remove USB power noise make it the ultimate companion for any audiophile or high-performance audio setup. The option to use an external power source, such as the iFi iPower2, offers unparalleled flexibility and upgrades your system to deliver pristine, noise-free sound. Whether you're streaming music, working with high-resolution audio, or using your system for professional purposes, the iDefender Max ensures that your sound is always clear, crisp, and free from interruptions.
