Q: Does the a20 6-pin version without bluetooth get power for the anr from the batteribox when I use a 6 pin to ga adapter
A: Yes, that is correct. The A20 will be powered via the AA batteries when you use this adapter.
Q: I'm considering to purchase a Bose A20 (with bluetooth) 6-pin option however would like to also use this headset with the "Bose A20 6-pin Redel to Fixed Wing Adapter" (for 2 pin aircrafts). Would I still be able to use the bluetooth option since this headset is 'panel powered', or does it have a AA battery power option in this 6-pin panel powered A20 headset?
A: Yes. If you get the Bose A20 with Bluetooth panel powered version it will terminate in the 6-pin Redel connector but it will also have a battery box. The aircraft electrical system will be used to power the ANR in the headset, however the Bluetooth is only powered via the AA batteries. This also gives you the benefit of being able to easily convert the headset (with this Redel to Fixed Wing adapter) to use in a non-powered environment. So, once you install this adapter you will use the battery box in the A20 for both ANR and Bluetooth.
Q: The Bose A20 with a 6 pin conector, will need batteries to run with this adapter? Will it work just like the A20 with the dual plug? Thanks
A: The 6-pin Redel connector will allow the Bose A20 to get power for the ANR system directly from the aircraft electrical system. However, the AA batteries in the battery box are still required to power the Bluetooth connection. Yes, it will work just like the A20 with the dual plugs (except that it will use less batteries).
Q: Will this work with a Lightspeed Zulu.2 headset which has the 6 pin connector (Lemo I think)?
A: No, this one will not work with the Lightspeed Zulu.2 headset because there is no way to power the headset one you have converted the plug. The Bose A20 panel power model includes a battery box which is why it works with the Bose A20. However, for the Lightspeed Zulu / Zulu.2 you can use the Bose X Panel Powered Adapter to Portable Fixed Wing Adapter which incorporates a battery box and will allow you to use your panel powered Zulu in an aircraft with standard dual jacks.
Q: Will this work with a Bose X, seems like it would with the standard 6 pin..
A: No, this will not work with the Bose X. It will only work with the newer Bose A20 model. For the Bose X, you will instead want the Bose X Panel Powered Adapter to Portable Fixed Wing Adapter.
