Wiring for 2 pin headset to TA4F connector

[JohnA]

I have a "no name" headset type wireless mic. It was originally wired for Sennheiser, and has only 2 wires (T/S): ground (sleeve) & signal (tip). I want to wire this to a TA4F connector in order to use it with a Shure LX-1 body pack.
A pin out or diagram, including any resistor or capacitor values would be great. I contacted Shure, but they wanted a schematic of the headset circuit. I do not have that info available. I also do not have the manufacturer name for the headsets, as they were bought "used". Thank you for your time.

Do you know if the headeset mics are dynamic or condenser? I did find http://pinouts.ru/Home/ta4_shure_pinout.shtml but since the mic and bodypack have to work together the one circuit affects the other and the values may depend on the mic itself. For example, here's two different approaches for the Sennheiser MKE2 microphone, http://shure.custhelp.com/app/answe...onnect-a-sennheiser-mke2-to-a-shure-bodypack?.

Hi Brad,
Thanks for reviewing my post. I have attached a couple of jpegs of the device. I was mistaken bout the original connector--it is T/R/S. But there are only 2 wires, signal & ground. I made measurements with a DMM, Ring to Sleeve is 0 ohms; Tip to R/S is 27.5Kohms. I was able to pass a signal through a TA4F connector to a Shure LX body pack by putting ground on pin 1, and shorting pin2 to pin 3, n/c pin 4. There was no signal unless pin 2 was shorted to pin 3. Since pin 2 is supposed to carry +5V bias, would this not indicate the headset is condenser? Thanks.
