Hello,
I bought a schoeps cmc3-pd microphone preamp body, and I need to make an adapter, or a battery pack to provide 12v phantom power with positive ground (negative phantom power).
I found a schematic for a 15v phantom supply (normal polarity, not positive ground), which I have attached to this post below (the schematic is from http://www.new-line.nl/?i=61).
If I wanted to make a power supply for the cmc3pd, would it work simply to use this circuit, reversing the polarity of the batteries and the capacitors? or is it more complicated that?
Many thanks for any help.
Josh
