I tried adjusting the mic sensitivity in service mode all the way up to 63, but it didn’t seem to make any difference. I have the wiring harness from Wings and Wheels. How would I go about switching pin 5 with pin 18?


The mic wire on my W&W AR4201 harness was on pin 18. If you want to move it to pin 5, unsolder it from 18, move it to 5, and solder it.

Pin-outs are in the manual.


Thanks. That seems simple enough.

It raises a related question though: the mic is a dynamic un-amplified mic (Peiker TM170). If I understand things correctly, the way the harness is currently wired (pin 18) would be for a standard, not a dynamic mic. Why would they do that? The Becker mic is a dynamic mic, as is the Peiker.
