Here' my situation... My two place aircraft is fitted with one headphone jack and one mic jack. The mic is keyed via SPST PTT switches in the control sticks. The intercom I have is a portable unit that inconveniently gives me two mic output plugs: one for pilot and one for copilot. Ostensibly, the two mic ouputs are to allow use of external DPDT PTT switches and a "Y" harness which would then plug into the aircraft's one mic jack. I understand that the normally open DPDT switches essentially shield one mic from the other and allow the "Y" cord to "mix" the mics into one output. However, I want to avoid the resulting cabling mess if I were to do this. So, I'm looking for a good way to combine the mic outputs into one output without causing too much signal deterioration. --Jose Read this topic online here: http://forums.matronics.com/viewtopic.php?p=342762#342762 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-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/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-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.
