Default Re: Confusion over DIN sockets

'Radio/diode' is Grundig terminology for a line input or output. It derives from the probable use of a radio as a signal source or external amplifier. The signal would come from / go to the top of the volume control, after the detector diode.

I don't know the recorder being discussed so can't help with specifics.
