hey now...
it is basicly two c414 mic capsules (ck12, I belive) mounted coincident. It does XY of variying degrees, M-S and blumlein.
Great mic.
However, I think the small diaphram c34 stereo mic sounds better. My ear just favors the small diaphram sound over the big ones.
Still, i'd own another c422 in a heartbeat. I've pulled some pretty nice stuff w/that sucker. Great stage mic.
