[Azden] Mic Pins needed for 2000

Sun, 7 Mar 2004 09:02:06 -0500

While the connectors are identical, some of the connections are not.  For
the 2000, the mic is on pin 12 and the mic common is on 11.....  same as
3000.  PTT is on pin 4......  same as 3000  PTT ground is on pin 2.....  
same as 3000.

Why have I called them different, that's because the control lines R0,
R1, and R2 are on different pins and on the 2000 pin 6 is squelch and on
the 3000 it's key lock.

And, while the pin numbers are the same, the drawing on the schematic is
reversed between the 2000 and the 3000.  That is, the pins are numbered
right to left on the 3000 schematic, but left to right on the 2000
schematic.  This is probably just a drawing difference, but you would be
best to check before you make any connections.

However, I do not suggest trying to use the connector by itself.  The
contacts are easily damaged and are the removable type, but you have to
have a special tool to remove them.  I have no idea where to get more. 
That is one of the reasons I went to the "jack in the mic" solution. 
Have done it on a number of sets and all worked fine.  The connectors for
the 2000 and 3000 are now, and have been for many years,
unobtainable.....  worth their weight in gold.

You still have to get the receive audio from the speaker jack on the rear
as it does not come out from the microphone connector.
