RCA Caps

About the RCA Caps

Cardas Audio RCA Signature Caps are designed to fit over unused female RCA connectors on amplifiers, preamplifiers, receivers, and other audio components. These caps eliminate electromagnetic interference (EMI) and radio frequency interference (RFI) noise absorption without shorting the inputs, which can be harmful to some preamps. Made from billet brass and nickel plated, they provide a solid shield that prevents EMI and RFI from entering the chassis through the RCA dielectric. Additionally, they protect delicate RCA connectors from dust and corrosion. The caps feature the Cardas Nautilus logo in a gold finish on a black background, combining elegant design with practical function. Sold in sets of 12, these caps have won an Editors' Choice Award from The Absolute Sound for their effectiveness in improving sound clarity and reducing noise.
