Does anyone have any ideas for what would be good on a microphone
preamplifier board ?
You see, the new breakout standard for preamplifiers or "skins" allows
reusable and interchangeable preamplifier boards :

I have had an idea for two types of microphone preamplifier boards :
* A preamp with electret microphones onboard going ultrasonic.
* A preamp which is capable of doing dynamic microphones as well as
phantom powered condenser microphones.
I would imagine around 30 to 40 dB of gain would be required for the
microphones.
There are a few questions. What sort of things are you looking for in a
microphone preamplifier ? For the outputs, do you want RCA or XLR ?
