Think there are two 4 pins on this cable he is using. SOME Heil mics use a 4 pin XLR plug on the mic itself. So, that is the 4 pin I was talking about. In case that wasn't clear.Just a heads up for proper wiring.
I believe this should be in the paperwork that came with the mic.
I don't believe there's any 8v to that mic. Pretty much like a standard four pin.
"The ‘soft touch’ PTT switch is wired to pins 3 and 4 for transmitter control with the microphone signal fed to pins 1 and 2 of the 4 pin XLR. The Heil HM -12 uses the HEIL CC-1 Connecting Cables."
It looks like it should be wired this way.
PTT, GND
Audio, GND
I have the same mic, sort of. It's the GM-5 with the wide and narrow switch, with the soft touch PTT. There's no voltage from radio, but then it's on a Kenwood. I really don't believe any of the four pin HF rigs have 8v from the radio. Someone correct me if I'm wrong.
