Why????:bdh::bdh:
Make sure that you put in a dropping resistor on the 13.8V line so you get the voltage down to 9V to run the RD mic... otherwise the RD mic will sound "windblown" and over-driven.

Would'nt some itty bitty diodes on the adapter step down the voltage? I'm a little rusty on doing it the resistor way. Do you have the formula right off hand?
