		      From this data I deduce that input #1 is always ported

    to both speakers (if connected) and headset audio

    irrespective of condition for any system controls.


	


   Does your PMA8000 already drive the speakers?

   If so, there is risk for creating a feed-back

   loop in your audio system if speaker signals

   are sampled and fed back into on of the system's

   inputs.



   Most pilots with sophisticated audio systems

   use headsets but in your case, you'll want

   to make sure that your PMA8000 speaker driving

   features are turned off. As I mentioned earlier,

   without wiring diagrams for the as-installed

   system, it's a challenge to catch all the

   'rats in the woodpile'.
