 |
|
I have a question for the hive mind.
I recently got around to adding the LEMO/Redel/Bose jacks for
headsets in my RV-8. The airplane was (and still is) wired for
stereo with standard jacks and a PS Engineering intercom. The
standard jacks work well.
My old Bose Series II ANR headset works fine plugged into the
standard jacks and using its adaptor and battery pack.
After discussing with the Bose tech support whether I should wire
into the existing jacks or all the way back to the intercom, they
said it didn't matter, so I took the easy way out and wired to the
existing jacks.
When I plug the headset into the 6-pin ANR connector, all is well
(good audio, good mike sidetone, etc.) until I turn the ANR on.
With the ANR turned on, I lose audio in the right earpiece (ANR
itself seems to work fine).
The headset works normally when plugged into the standard connectors
(through its adaptor) and battery pack, ANR and all.
All the connections seem to ohm out properly, although I have been
known to miswire things in the past.
The relevant wiring diagram can be found here on page 18:
