20 pcs Gold RCA SHORTING CAPS - Noise Stopper Gold Plated Cap Dust Protector RCA Input Plug

I use these to cover up phono plugs on my mixer that I am not currently using. They work well.

fit like a glove to cover up unused RCA inputs

OK.... Yes these are ok and do work but only under a few instances you should use these...1 = Did your amp or receiver originally have these on a second set of phono input ??2 = These are to be used ONLY on phono input and no where else.3 = If your amp or receiver didnt come with these , on a second set of phono inputs - DONT USE THEM WITHOUT INSTALLING A RESISTER, as they can short out a channel and cause major Amp or receiver damage... Look it up on line and you will see its true that these can KILL your Amp or receiver if it wasnt made for them or there is no resister installed to use with them.. FACT ..

Using these on high end integrated. Lowers noise floor tremendously. *note* only use these on inputs! For unused outputs you’ll have to buy caps that don’t have the center shorting pin.
