B&O turntable question

Probably pretty lame but here goes: I have a B&O 2000 table which I'm getting out of mothballs in order to listem to my LPs again. The cable is a DIN with a dual RCA/ground adapter attached (supplied by B&O). The RCA plugs are black and grey. Does anyone know how those colors relate to modern equipment?

The back of my phono preamp has white/red inputs.

Thanks, and apologies for a weak question, but one that has been on my mind.
