[AudioI] Microphone preamplifier

[Matt Flax]

Hi there,

The XLR preamplifier is setup to carry up to around 20.4 V (about 19.4 
dBu). The output preamplifier has a gain of 13 dB. The input 
preamplifier has a gain of -12.8 dB.

A good microphone preamplifier would require both phantom power (the 
power rail is available on the Pro and Isolated soundcards) and also a 
significant input gain of around 30 dB.

It would be great if enough people were interested in this to either 
design their own together, or given more time I can design one up.
