Two choices...

1. Instead of going to the "mic in" jack on the Sony, go to the
"line in" jack if there is one... or ...

2. Run a 100kohm resistor in series with the line between the phones jack and
the mic in jack with a 10kohm resistor to ground from the mic in jack. If it is
still too loud, diddle (that's a term for heuristic engineering) with the 10k
resistor down in value until it comes out clear.

shared these priceless pearls of wisdom:

-Help!
-
-I tried recording the Nav/Com audio to my Sony camcorder in a c172. The gain
-is so high it just sounds like saturated noise. I basically wired from the
-co-pilot's headset jack a cable to the sony 'mic in' jack. Has anyone here
-successfully recorded a flight with clean audio, and if so, how ?

-Thanks,
