Keep Out EMI and RFI in Style
Keep airborne EMI and RFI noise out of unused female RCA jacks and do it in style with Cardas Signature RCA Caps. Cardas Signature RCA Caps are functionally identical to standard RCA Caps from Cardas. But Signature Caps sport a designer look. They fit over unused female RCA connectors on the back of an amp, preamp, receiver, and other components to eliminate EMI and RF noise absorption. Unlike traditional shorting plugs, these caps do not short the inputs, and many preamps don't like shorted inputs.
Signature Caps are made of nickel-plated brass. The famous Cardas nautilus shell logo is 'floats' in a golden finish on a jet black background. The caps look so elegant, you'll be tempted to keep them on your desk. But use them to prevent both EMI and RFI from entering the chassis through the RCA dielectric. This is a more elegant and probably more effective solution than either shorting plugs or wrapping the plug in aluminum foil.
Cardas Signature Caps have the additional benefit of protecting the RCA input from dust and corrosion. When you're ready to use the input, pull off the Signature Cap and your input will be clean and ready.
