I have installed a GTN650 (COM1), GTR20 (COM2), and GMA 245 (Audio Panel)...the audio panel manual says failsafe mode connects pilot headphone/mic to COM1...it also says there is a separate failsafe audio input that will also be shorted to the pilot headphone if wired. It mentions possible use of series resistors for some combinations of external radios.
Questions: If I want COM2 (GTR20) to also be heard during failsafe mode, can I wire COM2 headphone to the failsafe input without resistors? G3X, GTR20, and GMA245 manuals say nothing additional that I can find. If I need to use resistors, what values to use, anywhere to find the circuit diagrams?
