I know I have seen it before, on older Tv's, was wondering what to look for to convert it to optical.mystery output

1 Answer 1


It's hard to say without knowing what TV it is. Since it's an RCA socket, there's a good chance that it is simply coaxial S/PDIF, rather than optical S/PDIF (TOSLINK). If this is the case, you will need a coaxial to optical S/PDIF converter such as this. I would ignore the 3-pin connector, especially if the user guide doesn't say what it's for.

  • Thanks! So, literally right after posting I realised that there was a box around the Coaxial S/PDIF and felt like an idiot, cause I was definitely looking at the three pin.

  • @ADSquared That puzzled me at first as well. The 3-pin should have been blanked off if it's meant for technicians.
