Best-Selling Budget Tweak of All-Time!
Essential Protection For All Unused RCA Jacks! We have sold over 30,000 of these Essential Budget Tweaks! Cardas RCA Caps fit over unused female RCA connectors in your system to eliminate EMI and RF noise absorption. Unlike traditional shorting plugs, these caps do not short the inputs (many pre amps do not like having their inputs shorted). Another difference is Cardas RCA Caps completely cover the RCA input with a solid shield of nickel and brass to prevent both EMI and RFI from entering the chassis through the RCA dielectric. The Cardas RCA Caps also protect delicate RCA plugs from dust and corrosion. 100% Music Direct Guaranteed!
