The MWA-RC brings triple protection to unused RCA jacks: dust blocking, vibration damping, and noise absorption. Unlike metal shorting pins, it is completely safe to use on both inputs and outputs without risk of short circuits.
The tuned polypropylene body suppresses vibrations transmitted to the RCA jack, while a 1 mm Sendust alloy electromagnetic wave absorbing sheet on top eliminates incoming noise by converting it to Joule heat. It also prevents moisture and dust from corroding contacts.
Use multiple caps for cumulative effect. Compatible with standard RCA jacks. The resin construction means no magnetic or conductive side effects. Four pieces per set.
