Right.

Pro gear doesn't use RCA plugs. But can use TRS.

Is "TRS" a mnemonic for something? All I can think of when I see it is
the Radio Shack/Tandy TRS-80, pronounced "Trash 80". ;-)

Tip ring sleeve. Unbalanced stereo or balanced mono. Or sometimes a mono
in and out on a mixer.

I'd guess originally designed for telephone exchanges. In the UK, the
telephone one is known as a type 316 and has a smaller tip than stereo
jack plugs. And is still in use - must have been designed over 100 years
ago. Dunno if the US one is the same.
