Hello everybody! I've recently bought two electret vintage microphones (Grundig GCMS 333), wich come with 6-pin DIN connector and need electric power to work.
My idea is to build a little box with DIN input connectors, XLR (or TRS) output connectors, and supply the voltage trough the phantom power of a mic preamp (48 V). The question is, the mics need a maximum of 20 V, so I have to make a voltage divider too. I've made one, but it doesn't work (!!), so could somebody help me with an specific-for audio purposes voltage divider scheme?
Thanx and cheers from Spain!
