iFi iSilencer MAX — USB-C Noise Filter with ANC3

Silence never sounded so good. Eliminate USB-related interference and noise.

The iFi iSilencer MAX is a next-generation USB-C noise filter designed to eliminate interference, jitter, and signal integrity issues in computer-based audio systems. USB ports on computers are often powered by poorly filtered supplies, allowing electrical noise to contaminate connected audio devices. The iSilencer MAX provides a simple, plug-and-play solution that restores clarity, timing, and musical coherence—so you can fully immerse yourself in your music.

Silence Never Sounded So Good

Whether you’re unwinding after a long day or seeking focus through music, pristine audio clarity is essential. The iSilencer MAX removes USB-related noise at its source, preventing data loss and timing errors that degrade sound quality—leaving your music cleaner, smoother, and more engaging.

Active Noise Cancellation III (ANC3)

iFi’s latest ANC3 technology actively cancels incoming EMI and RFI noise directly at the USB source. By removing interference before it reaches your DAC, music becomes more transparent, bass gains definition, and the overall presentation feels calmer and more refined.

Jitter Elimination

Internal precision circuitry reduces jitter by improving signal timing at the digital-to-analogue conversion stage. The result is enhanced dynamics, sharper detail, and a more natural musical flow.

REBalance Technology®

REBalance Technology® cleans up the digital signal and ensures that the data received by your DAC is identical to the original source. It also removes distortion caused by DC offset, which can manifest as audible clicks and pops through speakers or headphones.

Military-Grade Precision

Inspired by military radar cancellation techniques, iFi’s Active Noise Cancellation technology duplicates incoming interference and inverts its polarity—effectively cancelling it out. This approach reduces measured noise by up to 100× (40dB).

Combined with specialised jitter-elimination circuitry, this technology improves depth, timing accuracy, and overall musical cohesion—making music sound more dynamic and detailed.

Balanced, As All Things Should Be

To ensure maximum compatibility with modern devices, the iSilencer MAX supports USB-C Power Delivery up to 100W (20V / 5A). This allows it to work with a wide range of equipment—from USB DACs to high-power USB-C devices— without compromising performance or charging capability.

Double Down on Noise Reduction

For even greater effectiveness, the iSilencer MAX can be used in multiple ways:

• Placed between the PC and a USB audio device
• Inserted into an unused USB port to reduce system-wide noise
• Using two iSilencer MAX units doubles noise reduction via dual ANC circuits

With full USB 3.0 support and backwards compatibility with USB 2.0, the iSilencer MAX does not limit data transfer speed or high-resolution audio playback.
