Need a mic schematic or pinout for gooseneck desk mic

Been a LOOOOONG time since I have been here but have a question.
I need a schematic or at very least the pinout for a desk mic.
It is the oval base with the slim flex gooseneck.
Numbers on the bottom are model B1914A
and the barcode strip says MBMN 1000e
Anyone able to help ?
I have several of these and would like to make some
crossover/adapter cables to use them on some other
radios I have.

Thanks in advance,
Phrawg

A manufacturer's name, as well as the number of wires in the cable, would be a great help in answering your question and helping you out with this.

The B1914 is the gooseneck mic for the MIP5000 console.

If you believe this dealer's brochure there are no specs available for the unit:

KInda figures. So much expensive disposable stuff now days. well let
me ask another way then. Anyone know the "pin-in" for the 5000 console
and that would sure give a clue. The board in the mic has 0nly a few
surface mount caps and 3 small 3 pin devices on it.
Thanks for the input so far.

And I thank you sir. I will look at that config and see if I cant then fabricate some
form of a "crossover" cable that will allow commection into earlier Radius, Maxtrac,
etc that use the 8 pin modular. Seems that should be do-able.

Hey Phrawg great to see you back! Keep us posted on this, I'm curious myself! We use these on the MCC 5500 & MCC 7500 consoles too.

I was wondering if anyone has tried interfacing this mic to a standard Motorola mobile radio.

won't work.. will sound dull because that mic is a 200 ohm microphone..

So it needs a preamp.
