AudioQuest RCA Noise-Stopper Caps (Set of 10)

We are able to ship to United States - View Rates


AudioQuest RCA Noise-Stopper Caps fit over unused RCA Phono sockets, preventing RFI and EMI noise from entering the active circuit.

In a world immersed in RF/EMI interference we all need the sound of silence. Nothing makes an audio/video system more irritable than RF interference- the bane of dynamics and clarity. To reduce the amount of RF interference entering your system we recommend capping all unused RCA and XLR inputs / outputs. You’ll be pleasantly rewarded with a blacker background, deeper sound stage, and a richer more satisfying overall experience.

Noise-Stopper Caps also protect against dust and corrosion. Sold in packs of 10 Noise-Stoppers.


  • Prevents RFI + EMI noise from entering active circuitry.
  • Protects against dust + corrosion.


  • 10 x RCA Connector Noise-Stopper Caps
