[Elecraft] Heil GM4 to K3

[Gary Smith]

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,
