Cap Those Unused USB-A Inputs or Outputs
Extraneous and unwanted RF / EMI signals are everywhere. Cell phones, computers, microwave ovens, and other devices spew these sources of electrical noise that highly sensitive audio and theater components can pick up.
The AudioQuest Noise-Stopper Caps fit over unused USB inputs or outputs, preventing RFI and EMI noise from entering the active circuit. Noise-Stopper Caps also protect against dust and corrosion. These Noise-Stoppers are for USB-A inputs or outputs.
This package contains a set of four caps.
