Telex Airman 850 Tech. advice needed!! (d/heading ANR?

[Anti-Ice]

I need some electrical Guru to teach me how to get my Telex 850 ANR to work in the pax cabin. Anyone out there have any experience with this situation? Thanks in advance!!

I own the Airman 850. I often am required to deadhead in the passenger cabin of commercial airlines. Most airlines these days have in-flight entertainment systems that utilize a 1/8 " standard headset jack. Now I can find a common adapter to allow me to use my airman 850 to listen to the entertainment...HOWEVER the ANR noise cancelling doesn't work due to lack of microphone power.

Is there any sort of adapter that I can make or buy that will allow me to draw power from the headset output and thus give me noise cancelling while I am sitting in the passenger cabin? Will a 1/8" headset output jack provide enough (or possible too much) power to operate the ANR? Could this fry my mic?

I'm thinking a simple splitter to go from one headset jack into two. Then upsize the 1/8" with a common radio shack adaptor. The tricky part comes from having to cut off the other half of the splitter (2nd headset output) and solder on a 'female' microphone receptacle that will fit my mic. plug. This should provide some sort of voltage/amps to the mic and (hopefully) power the ANR?

Thanks.

From what I can see...the entertainment headset output jacks have no>>>>> DC...riding with the AC signal...which is of course the audio>>>>>>>>(AC)

What you would need to do is have an adapter to input the power that comes over the intercom in the cockpit. Now you might also have issues with the resistance on the intercom being different than that of the entertainment system. I would have a chat with an avionics guy see if they can help you.
