AudioQuest RCA Noise Stopper Caps - Premium RCA Jack Protectors for Hi-Fi & Home Theater Systems - Reduce Noise & Protect Audio Connections - Perfect for Stereo, AV Receivers, and Professional Audio Equipment

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. You’ll be pleasantly rewarded with a blacker background, a deeper sound stage, and a richer more satisfying overall experience.
