Affordable RCA Protection from Both Oxidation and RFI/EMI
Audio Additives has come up with a much more affordable RCA Cap. These are indispensable for keeping RFI/EMI from contaminating your audio/video systems. Simply place Audio Additives RCA Caps on the unused RCA inputs and outputs in your system, greatly lowering your system's noise floor and keeping your contacts clean. This great budget tweak is simple to use, very effective, and at these prices, you have no excuse for having a single uncovered RCA jack on your components.
Extremely effective, Audio Additive caps are made from metallized plastic. These RCA caps are the real deal, they just weigh a bit less than all-metal caps. We still recommend using all-metal caps in high-resolution systems, but the Audio Additives RCA Caps offer an inexpensive alternative for covering up all the open inputs/outputs on the back of any of your gear. Highly recommended.
