My mic is broken, so I tried to fix the headset by cutting the wires. Then I striped the wires. But I noticed that there were only 4 wires, yet there were 5 places to solder. Looking at the part, There are 3 connected wires that I have not cut off yet and there is 1 wire broken. That leaves 1 wire and 2 soldering spots unaccounted for. When I look at the 2 soldering places, they both have a small strand there, so I can not tell which one the wire broke off of. I tried searching online to find the blueprint of Altec Lansing AHS322, but I had no luck. I just need to see where the wires go. Does anyone have any ideas?

If you're trying to convert a STEREO output to feed MONO headphones, the best is to use a resistive splitter network as shown.
There are adapters out there that simply short the two L/R signals from the stereo, but you run a risk of overloading the output stages of your amp.
The resistive network places a current-limiting resistor on each stereo output in series, so eliminating shorts and overload.
If using a mic-enabled headset, the jack has 4 connectors, the back one nearest the plastic case being for MIC.
Mono: Tip, Sleeve.
Stereo: Tip, Ring, Sleeve.
Incl Mic: Tip, Ring, Sleeve, Mic.
Tip is Left, usually Green.
Ring is Right, usually Red.
Sleeve is common GND, usually bare copper or black.
Mic can vary according to manufacturer. Seen striped colors, white, red, purple.
These thin shellac-coated wires are sometimes difficult to solder, so here are some tips:
Using a combination of fine emery paper, craft-knife and flame, try to burn/scrape/clean about 5 mm from each wire.
Copper should be shiny without shellac color showing at end.
To burn the shellac off, best hold the wire 5 mm or so back with pliers or fingers. The shellac varnish may ignite the whole wire if you don't block it first.
Diagrams and drawings should help to clarify the text.

Strip the wires back further. There make be more broken wires. Put all of the colors together and include the bare copper wire. That wire is the ground and there will be poor performance or no performance if the headset is not wired properly.

how do tou fix the after glow ax.4.the problem whith it is that my freinds can hear me but i have to un plug it to hear them

Don't know why answers for different type of headsets shown up on a question about the Telex 850. Probably there is an issue with the cord. The cord has two shielded "double" wires on each pair. The ones for the mic are "white" and "light blue". May be one is cut preventing the mic to work. Look around for a local avionics shop, they should be able to fix it. Hope this helps ;)

It could be that your mic is clogged up or dirty, or that you have a loose or broken wire. No way to know. If you try to clean the mic with a damp cloth, do not run it under water. Surgery drinks will leave crystals in the mic, which do not allow sound through. If it still won't work you may need to replace the headset.

Good luck from Headsets Direct!

I noticed that Avaya headset is different from the Avaya handset or any other standard headset: The outer two pins are switched.

Avaya-Headset-pinning is like this:
Look to the RJ11 and turn it until you see leads from top and from front, then from left to right you look at
1) mic 5V
2) speak
3) speak
4) mic gnd

RJ11 of Avaya-handset and any standard headset/handset from the supermarket:
1) mic gnd
2) speak
3) speak
4) mic 5V

Hope that helps.

This is probably a broken wire inside. the microphone piece moves back and forth to turn this unit off and on and the wires have broken because of it. there is a similiar problem with the H800 as the mic extends in and out to turn it on and off.

the mic cable is probably broken its very simple 2 wires and can be fixed on your own by useing a soldering iron for example.

most likely a broken wire inside. it's dead imo.

Buy other.
