Gentlemen, forget the "theory" and focus on practice.
I have just disassembled my 30 year old Shure 444 and as I suspected, it has
both grounds tied together to pin 2.
To be exact, pin 2 has the cable shield attached and the "mic-" and "PTT
Gnd" are both tied to this.
There is yet another unused wire in the cable which I could use for the mic-
but I still face one more problem:
How on earth do you make a good electrical and mechanical connection to the
4-pole plug's case?
This has not been provisioned for.
I thought maybe my old plug was outdated, so I inspected the new plug that
shipped with my Orion and it is exactly the same.
The only way I see to do this is to run the shield back along the outside of
the cable and secure with the strain release.
Anyone else been there and done?
How?
