SP-SPSB-11 with Church audio mics

(1/3) > >>

one8ung:
Can i run a pair of CA-11 mics on a 12volt SP-SPSB-11

one8ung:
Just contacted chris church and he said it’s slightly to much volts.

kuba e:
I think you can put some small resistor in the microphone jack to drop 12V down. I remember Chris said that Ca11 has current consumption less than 1mA with 9V battery box.  Maybe Chris or someone who knows electronics could advise you the resistor size.

Interesting. When I bought mine way back when they were called CA-STC-11 he said 12v was OK.

Chrisedge:
I would also spring for one of these battery boxes if it could be used with CA-14's (Both Omnis/Cards)

I am really wanting a new TINY battery box. Make things simpler and smaller.
