CA-Ugly vs SP-SPSB-10


I soldered two DPA 4061 microphones to a 1/8-inch stereo jack.
The specifications says the microphones need Min. 5 V - max. 10 V

I measure 2x 4.35v on the 9v CA-Ugly box, now I thought I was smart and bought a 12v SP-SPSB-10 battery box and was hoping on 2x 6v but now I measure 2x 4.1v on it!

I measure with a standard electrical tester, has anyone measured with a true RMS meter?

breakonthru:
10V is too high dont run those with a 12V bat box

"RMS" doesnt apply to dc voltage measurements

one8ung:
The Ugly box is a parallel circuit in my understanding that's why both mics get 4.35 V

Or am I seeing that wrong too?

audBall:
SP will modify the SPSB-10 to accept the smaller (mini) 9V batteries and did for mine. I haven't tested the output voltage or how long they last though.

one8ung:
Installed a fresh battery but it gives me 4,1 volts again
