Hey simple question, I'm sure someone here can answer.
I just bought (another) old hi fi amplifier. It uses 5 pin DIN connectors.
It has inputs labelled for TAPE/TUNER + the configuration of which pin sends/recieve which signal i.e Left/Right/Earth/Right/Left for the tape.
Can someone tell me what the input labelled X.C is for? Also unsure what O stands for in the context of Left/Right/Earth (is it just nothing?)
