First of all I am a studio engineer and and now reverting back to my
live days. I have just built a Jazz, Blues and Alt. Rock club and I
have 3 senn. wireless handhelds, and 6 senn wireless guitar packs. My
wireless guitar body packs say mic/line on the input plug 1/8". I have
some Audio Tech. ATM-35 mics for horns and drums and would like to plug
them in wireless. I need to build a phantom bodypack batt. powered.
My mics take 11v to 48v. I was thinking of building one with 1 or 2
12v batts and blocking caps but I thought I would get your guys ideas
first. which are the best caps to use and I would like to use AA Batts
instead of 12v batts cause that is what all my senn. stuff uses (AA
Batts.) What do you all say

I say that five 9V batteries in series for 45V will weigh a whole lot
less than a whole stack of AA cells, and if you want to do anything else
you'll be into designing a DC-DC converter which is no fun.

Have you considered the Sennheiser butt plug transmitters which actually
provide phantom power?
