Keep Out EMI and RFI
Keep airborne EMI and RFI noise out of unused XLR jacks and do it in style with Cardas XLR Caps. They fit over unused XLR 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 components don't like shorted inputs.
XLR 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 XLR connections. This is a more elegant and probably more effective solution than either shorting plugs or wrapping the plug in aluminum foil.
Cardas XLR Caps have the additional benefit of protecting the XLR input from dust and corrosion. When you're ready to use the input, pull off the XLR Cap, and your input will be clean and ready.
