@ Mike
Thanks for the diagram, it definitely helps!
Just to make sure I fully understand this circuit, the transformer "steps" down the impedance of the aircraft to that of the mp3 player, and the headset...ie 100-500ohm to 10-30 ohm. Does the transformer also isolate the aircraft from the rest of the circuit? (That is what I understood from your example.)
I also realized the aircraft audio out is mono, can I use just one transformer, prior to splitting the signal?
Can I also drop the pot? As I don't need a separate volume control, or does it serve another purpose?
In your illustration R1(1/2w, 10ohm resistor), is there to protect the Garmin in your case, mp3 in mine....Right?
I'm sorry for so many questions, but as you can probably tell I'm not an engineer, and I'm new at this stuff. I am reading books and trying to learn, and I apologize. I appreciate everyones help!
