Cover all the unused RCA inputs in your system with the RCA caps to keep unwanted noise from interfering with your components. Our RCA caps easily slide over unused RCA jacks and provide both sonic and environmental protection. These noise-stopper caps are grounding plugs designed to help block out unwanted noise. Simply slip a cap over the open inputs on the back of your Hi-Fi equipment. You will notice that noise-stopper caps lower the noise floor and allow your equipment to perform at its fullest potential. For the elimination of electromagnetic noise pickup from unused RCA connectors in audio and video equipment, these caps also offer dustproof protection. Gold-plated brass construction ensures ultra shielding and long-lasting protection. They shield against RFI, EMI, dust, and corrosion. Suitable for either shorting or non-shorting applications.
