Headset Question.. HELP :(

[phil.marsh]

Hi... This is my first post on here...
Basically today I was given a new headset, I believe it is a Telex 3100.
The problem is there is only one jack coming from the headset and the aircraft I fly require dual jacks one for the mic and one for the earphones.
Is this a helicopter headset? or just a strange headset?

THANK YOU :)

Probably a listen only headset.

Or if the plug looks like anything except an audio plug then it's an airbus plug.

[phil.marsh]

It has a Mic and the jack has 3 white bands on the jack which means it has stereo and mic so I dont think its a listen only. and its not an airbus plug as the headset is basically a standard G/A headset... :ugh:

Sounds like a helicopter plug to me if its a single, fat connector (U-92A/U), you can get adapters for those....

Possibly an Air3100l, have a look at this http://mag.telex.com/telex/documentation/air-3100_air-3100l_user_instructions.pdf (http://mag.telex.com/telex/documentation/air-3100_air-3100l_user_instructions.pdf)
Pages 2&3 have pictures, you can probably rewire it or get an adaptor.

Its defiantly the 3100L any ideas where I could find an Adaptor? Or how to rewire it :)

Sorry Phil, but the 3100L does NOT have a microphone - the L version is the headphone-only version of the 3100.

The wiring needed for GA use is shown within the User Manual linked by DB6.

Exactly what version/wiring you have currently is near impossible to figure out, particularly since the Telex website is very nearly the worst website on the planet. :ugh:

It's a good bet the unit you have is wired for helicopter use.

All I know is it has the usual boom mic but a single plug :ugh: do helicopters use single jacks then?

[GarageYears]

do helicopters use single jacks then? Yep!

The plug will be shortish, with 4 conductors, tip and 3 rings.

That's not mine then. It's pretty much Identicle to one of the G/A plugs same length and thickness with a screw ring on it?

This is the headset i have with the plug I'm trying to describe...

Does it look something very much like this?

This is a PJ-051 connector (I believe you said yours has a locking screw-ring at the body?)

Then my friend what you have here is a "ground crew headset" - this is the headset the ground crew will use to plug up to the aircraft. The single plug makes this easier. A common return 'signal-ground' is used for mic and headphone, hence only 3-conductors are used (mic+, headphone+ and common signal-return).

What you need is a S830 to PJ055B/PJ068 adaptor. The S830 mates with the PJ-051.

Couldn't find one in a quick search on the web (I think David Clark makes one...), but your local avionics shop should be able to knock one up.

Ahhhh drat...
Well to be honest im tempted to sell it instead of fixing it less hassle.
Thank you so much for all your help :)
