Only one wire on the mic? Wouldn't you be creating a ground loop if the jack returns to ground through the airframe? The jacks need to be isolated from ground.You can't tell from the video which terminal is the tip, ring or barrel. What is the difference between the audio and the headphone? What happens on the other end where it connects to the radio? Where's the PTT?
very wrong technique. Shield connected at jacks? since when? Only one wire on headphone jack? this install will be noisy and very unreliable. For correct connection look at page B-2 in this install manual as an example : static.garmin.com/pumac/190-00917-01_E.pdf
This video was produced when I was in an avionics technician class at a local CC then after first semester a new instructor came aboard and said everything we learned was incorrect so I withdrew from the class
Floating ground at the HeadPhones/Mic side (no connection), The Grounding as shown in the video would be done at the Backplane (grounding lug) of the intercom avionics side. Also... insulation spacers would be used to isolate the HP/Mic jacks from the aircraft Ground or airframe.
Excellent. I was searching for information on an aviation headphone amplifier, but this was a great explanation of a little bit more than I wanted for myself. Thanks.
Wires are stripped back far enough to allow tinning and to be pulled through the holes and bent back. The use of flux is not an issue...or do it anyway you wish. I think the students did a fine job,
too much bro, do a quickie for all of us that need that one little detail were missing.
you start with white hands and end the video with dark ones..lol.. great video.. can you make one for audio panel?
Bruh just buy an earphone smh.
Which soldering iron you use ?

Where do you buy this Aviation wire 20/3 shielded?
prowireusa.com I bought my wire from there. they have the solder sleeves also. good prices too.

So what would be the correct way to ground the shield?

Good video for repair

If the HP and mic share a common then you would wire differently.
Excellent job -thank you- helped me repair my intercom!
Your very welcome this was just a project my avionics class put together a few years ago!
Only one wire on the headphone socket? What if the headphones don't share a common return with the mic? Very poor.
Whats with the massive amount of flux and why are you stripping so far back? This may look neat but it is poor technique.
