High Definition, Minimum Interference

HDMI Noise Filter with Surge Protection 

Enhance your entertainment experience by eliminating interference. 

We understand how important it is for you to disconnect and immerse yourself in your favourite media; watching movies or playing games to escape and unwind.  

However, HDMI connections often carry noise and interference, generated by the circuitry of electronic devices in the signal chain, causing visual artifacts and timing issues that only work to pull you out of the experience. 

With proprietary noise cancellation and jitter elimination, the HDMI iSilencer restores the true quality of your media, delivering crystal-clear audio and picture-perfect video. 

Escape into your favourite movies like never before.

Key Features Explained

Active Noise Cancellation II 

ANC2 Technology removes incoming noise and interference generated by electronic devices in your system, to remove visual artifacts.

Jitter Elimination​

The circuitry inside the HDMI iSIlencer reduces jitter, improving timing at the conversion stage and enhancing both contrast and colour accuracy.

Surge Protection 

The HDMI iSilencer suppresses excess voltage, keeping components safe and ensuring continuous operation.

Picture Perfect

Inspired by military radar cancellation techniques, our proprietary Active Noise Cancellation technology duplicates incoming noise signals from the source device and inverts the polarity, cancelling out incoming electromagnetic and radio interference. This technology improves depth and dimensionality in both colour reproduction and black levels – and means that measured noise drops by 100x (40dB) in comparison to typical noise filters.

Coupled with specialised circuitry designed to eliminate jitter, this innovative blend of technology dramatically enhances colour depth and black level precision, creating a more immersive viewing experience.

Pure Passthrough 

Despite its active filtration, the HDMI iSilencer lets digital signals pass through perfectly to meet the following video and connection standards:

  • Ultra HD/HDR 8K/60Hz
  • Ultra HD/HDR 4K/120Hz
  • HDMI 2.1 and all previous HDMI versions
Coupled with specialised circuitry designed to eliminate jitter, this innovative blend of technology dramatically enhances colour depth and black level precision, creating a more immersive viewing experience.

Protect and Preserve

The HDMI iSilencer acts as a shield for connected A/V components, featuring a Transient Voltage Suppression (TVS) system to ensure smooth and continuous operation. You’ll never have to worry about surges, lightning strikes, EMI or electrostatic discharges interrupting your movie night or gaming session

How do I use? Simply insert the HDMI iSilencer between: 

A media device (Apple TV, Fire Stick) and your TV, for deeper blacks and enhanced HDR performance

Between your PC and your monitor, forsharper text and true-to-source colours

An AV receiver and a projector, forreliable 8K playback and better brightness uniformity

SilentPower Reviews


"With the iPower2 the noise disappeared completely with the volume at maximum! That silence is what I expected. I heard the music better! The ZEN Air phono with the addition of the iPower2 goes from being a surprising device for the price, to being surprising for its performance"

The iPower X fever-level transformers introduced this time provide the purest DC power supply equipment. Power supply, iPower X is an AC / DC transformer with extremely low noise. Its small volume is filled with a lot of ifi Audio’s exclusive technologies and fever materials

I believe it is a great everyday carry accessory not only for sensitive IEM/Headphone users but also for beefy headphone amplifier owners who would like to hook up their IEMs to these amps and crank the volume as far as they can. The iEMatch 4.4mm gets the highest recommendation I can give to an audio accessory.

"This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life"
