Heil GM4 to K3

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

Re: Heil GM4 to K3

Check the Heil web site. Should have diagram of mic end. Just match it up with K3 diagram. Or just get the Kenwood cable from. Heil.

the Heil 4 pin XLR uses pins 3 and 4 for PTT , pin 2 for
the Mic, and pin 1 is shield/ground.

Re: Heil GM4 to K3

Thanks for the suggestion. I'd found this site earlier but didn't see
the mic pin info on it, just the info on the K3.
