Not getting any answers and I need to order ASAP, so i'm changing the Subject Title. Any problems with running the SP-SPSB-10 12v battery box to my CA-14 omni's? I know Chris Church makes 9v battery boxes for his mics, but I can get the 12v from SP right away.

I can tell you that I've run the SPSB-10 into CA-11s many times with no issues,both the old model with switchable rolloff and the new one without (their numbering changed recently and what used to be the SPSB-10 is now the SBSP-11)
Should be fine.
I've never had a problem using the 12v battery box from Sound Professionals with my CA 14 omnis or cards.
I think Chris said somewhere 12v is the max voltage.
Don't exceed 12V, but that possibility would be rather remote anyway.
Thanks everyone!
