      What do you mean by stereo wire? It’s got 3 contacts on the 3.5mm jack, that’s enough to transfer analog stereo (GND, L, R).

          It’s for bias to the mic. Condenser mics need it to apply bias to one of the leads of the mic so it can amplify the sound before sending it to the input of the card. Some mics don’t require that (self-biased) so in that case, the R pin (middle ring) goes to GND.

              The link doesn’t open, says connection refused 🤷.

              Regardless, if it doesn’t require the bias pin, the mic is self-biased or biased through another source (use the same wire for the signal to get bias, this is easy, you just use a cap to decouple the signal from the bias).
