I just picked up a Heil goldline GM-4 mic and it has an XLR connector with 4 pins. I've been trying to find what the pins represent and as much as I've been able to figure pin 4 =PTT and pin 3 = shield/ground. I can't figure out what pin 2 and pin 1 go to, one of them has to be mic, it's not an electret mic so it does not need power. Below are the pin values for the K3
1 Mic audio, low-Z (~600 ohms) 2 PTT 3 DOWN button * 4 UP button * 5 FUNCTION button * 6 8V (10 mA max) 7, 8 Ground Anyone know what 1 & 2 on the mic connect to? 73, Gary KA1J --- This email is free from viruses and malware because avast!
