 |
|
Dear Listers,
I bought a couple pairs of the new Bose A20's for the RV-8 and they are very nice. NR is better than the Bose X's and they seem to fit my head a little better too.
But I quickly discovered that with the A20's you now have to hit the NR Power button *every time* you start the aircraft even if you have them panel powered. The older Bose X headsets have a slide switch for the NR power and so you can just put the slide switch in the On position and not worry about it.
I really didn't like having to turn the NR on all the time and having to remind my passengers about it, so I came up with a modification that will automatically turn the NR on when panel power is applied. Its pretty simple, but requires some special tools. Its completely self-contained inside the Control Module and works great. The modification is generally only for installations that are panel-powered, but you could do the modification to a unit that is normally battery powered with no adverse effect. With the modification, the NR Power button will work normally in battery power installations.
I created web page on the procedure including step-by-step photos and instructions. Feedback is welcome.

Matt, you rock! That's awesome that you found a way to do
this. I'll definitely be taking at least one of mine
apart and trying this. If it goes well, I'll do 'em all.
It's the single thing I wish they had a dip switch for
that you could enable, and you got the answer. Thanks
for the great write-up.

Very cool! I'm glad to hear others feel that same way and can utilize the procedure. Let me know how it works for you.

Do you have a p/n or spec on the capacitor you used? I'd like
to try to buy the exact correct one to match what you did, or
at least a real similar one.

I used a part described as "Package 1208, 50v X7R 10% .1uF" that I had in my parts drawer. Just about any .1uf cap will probably due, so don't sweat it too much. They just have to be small enough to lay flat and not hit the cover when its all put back together. I got the ones I have from Frys:

Picture shown doesn't match the actual part. Looks like they're in stock and will ship them.
