I'm searching schematics to build a figure eight mic with Pansonic capsules
(omni). What interest me is how to wire the 2 capsules for balanced output and
how to phantom power the capsules (48v) since I know one capsule must be out of
phase and the voltage must be reduced to 9 volts.
Thank in advance.

This was discussed in the Yahoo discussion group MicDIYers;

Bottom line -- two omnis can make a figure-8 dipole,
but the response curve is not flat.

One MicDIYer has made fig-8 (actually M-S) from
Panasonic cardioids; photos and plans are in the
group area.
