MonosaudioRCA Male Plugs RCA Dust Caps, 8Pcs RCA Shorting Plugs RCA Shileding Caps, Detachable Center Pin Noise Stopper Dust Proof Protectors for Audio,Speakers,Subwoofers,Amplifier(Gold Plated)

I bought these to plug into the back of my Emotiva integrated amp to assist with noise & interference. snug fit on the RCA inputs/outputs. I like the fact that the male piece unscrews and I was able to use the male ended caps for my inputs and the female caps for my outputs. I was able to cap all inputs with 1 set. would recommend.

These actually stopped an intermittent hiss I was experiencing on my Presonus Eris 4.5 powered monitors. I suspected it was some kind of interference and decided to try these before replacing them. Glad I did.If you have active, but unused rca inputs on a device thats experiencing audible interference, try these out.

Love it for keeping dust out and simplifying rear connections on my preamp when I need to disconnect and reconnect things

The center pin can be unscrewed if short is not good option - very cleaver designVery good quality …

I used this to preserve my rcas input that not being use. I dont hear any changes, imo

It protect and cover unused rca plug.Fast delivery with quality product

Everything Ok
