"Mic Bias" is a SUPPLY for both "MIC_IN" and "Mic Jack", so it should
look like:

                       "Mic Jack", "Mic Bias",
                       "MIC_IN", "Mic Bias",

Not really. The circuit:
MIC_IN <-- capacitor <--> Mic Jack
                      /
            Mic Bias /

DC can not pass the capacitor. So Mic Bias only supply Jack.

Thanks
Richard
