Cardas RF/EMI Noise Blocking RCA Caps

Cardas Audio created these noise blocking caps to eliminate electronic noise entry through unused panel mount connectors. They simply plug in over the connector and noise can't enter.

Eliminating noise wherever possible will improve every aspect of system performance. There will be more detail, a greater sense of space, and more accurate dynamic reproduction. Eliminating noise is an incremental effort because it enters your gear in so many different ways.The more entry points you address the better you can expect your setup to perform.

Take a look at the back of your high-end surround processor or receiver and you'll see why noise entry through open connectors is a problem. I'll bet you can find plenty of unused input connections that need to be capped. This is an upgrade that works on every type of home entertainment system and it's easy to do.

Cardas caps fit neatly over RCA jacks, XLR jacks, XLR plugs, BNC jacks, and S-video jacks. They don't short the plug, they just keep noise out. This is a very simple, cost effective upgrade that exposes more information and reduces listener fatigue.
