LORDWORLD HDMI iSilencer Noise Filter Surge Protection 8K 60Hz 4K 120Hz

SKU CH-X9D9-JYF73

HDMI noise filter with active cancellation and surge protection for 8K 60Hz and 4K 120Hz systems

  • Cleaner audio-visual experience through active noise cancellation technology
  • Sharper dark-scene detail and lower audio noise via jitter elimination
  • Equipment protected from voltage spikes by built-in TVS surge suppressor
  • Ready for 8K at 60 Hz and 4K at 120 Hz with Ultra High-Speed HDMI cable
  • Works with HDMI 2.1 and earlier versions for broad system compatibility

Optimised for Large-Screen Systems

This HDMI noise filter targets installations with 65-inch or larger 4K televisions paired with dedicated AV amplifiers or processors. In these configurations, signal degradation is most audible and visible, so the device focuses on cleaning the digital path before it reaches the display or processor. Buyers using smaller screens or integrated soundbars will see less benefit.

Sustained Signal Integrity

Active noise cancellation operates continuously across the full bandwidth, suppressing system noise that accumulates during long viewing sessions rather than only during brief peaks. Jitter elimination steadies the clock signal over extended periods, preserving shadow detail in dark scenes and lowering the background audio floor. The integrated transient voltage suppressor clamps surges the moment they appear, protecting connected gear throughout the entire operating time.

8K 60Hz and 4K 120Hz Compatibility

The filter passes Ultra HD HDR signals at 8K 60Hz and 4K 120Hz when paired with an Ultra High-Speed HDMI cable, and remains fully backward compatible with HDMI 2.1 and earlier versions. It is not a signal booster or cable extender, so runs beyond standard cable lengths still require active optical or amplified solutions.

Questions about this item

Does the iSilencer generate any heat or noise when it runs continuously in an 8K 60Hz system?

The unit is a passive inline filter with active noise cancellation circuitry; it draws minimal power from the HDMI line and produces no audible fan noise or measurable heat during all-day operation.

What must I already own to use this filter with a 4K 120Hz display?

You need an Ultra High-Speed HDMI cable and a source or display with an HDMI 2.1 port to pass 4K 120Hz signals through the iSilencer.

Will it work with my older AV amplifier that only has HDMI 2.0 ports?

Yes, the filter is backward compatible with earlier HDMI versions, so it functions normally with HDMI 2.0 equipment while still providing surge protection and jitter elimination.
