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. http://www.matronics.com/BoseA20AutoOnModification/ Matt - Matt Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 170+ Hours TTSN - Rebuilding Fuselage After Landing Mishap... ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv7-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV7-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv7-list Browse Digests http://www.matronics.com/digest/rv7-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
