such a stupid question (probably)

[fusion]

Now this may sound obvious but I've searched around and found opposing answers on the matter...

Question is, on a RCA phono connector, which polarity is the prong and which is the surrounding thingy. Common sense tells me the prong is positive but I have read otherwise when trying to use google and searching here didnt help me so i suppose everybody knows lol..

Thanks

On almost all RCA connectors, especially those used on audio equipment, the center pin is signal and the outer ring is ground.

Yes, you can almost think of it as an extension of the (usually) connected coaxial cable, and its design reinforces a shielding effect.
