Gefell MV692 - Tuchel connector pins

[tomekstas]

Hi

Does anyone know how to wire Gefell 7-pin Tuchel connector from: Gefell RFT N692 power supply via a C61 cable to MV692 condenser microphone ?

I checked all pins on mic connector and there is correct +12.61 V supply voltage (on pins 1 and 2) - as on attached pictures below, but looking at the circuit diagram and some net information – that pins are for audio signal, and DC voltage should be on pins: 3 and 4, but I`m not sure is it correct and I dont want to burn anything. It seems that I have original C61 cable and it should be working fine, but there is no signal from microphone is such connection like on the pictures below. /or maybe somebody before me swap those pins connection on that cable, I have no idea ??

Is anybody able to help ?

Your meter gives a positive reading with the negative probe connected to pin 4, which is the +12.6V. Looks like + and supply GND have been swapped in the cable or in the PSU.
