Bose® Headset A20 6 Pin to Helicopter Adapter

Allows you to use a Bose A20 panel powered headset in a helicopter that is not specifically wired with a 6-pin Redel connector. Simply plug your 6-pin Redel connector from the Bose A20 to this adapter and you'll have a single U/174 plug that can be used in most helicopter. Adapter measures 21".

Using this adapter how does the Bose A20 get power for the ANR as it converts to a plug type without batteries and will this work with any other Bose headset model?
What people may miss is that the panel powered Bose A20 (Lemo plug type) headsets have a spot in the volume control box for 2 AA batteries so you can use this adapter and it will get its power for the ANR. This adapter can only be used for a Bose A20 headset not older models.
