That may be a good idea to have an attenuated channel
just in case I ever have a clipping problem. I thought
100uF was rather huge but that is what they show in the
AKG booklet. Maybe because it is a low-z mic? Probably 
of no concern unless I record bullfrogs. I will look in 
Digikey for poly caps.
