im new to reading schematics and whatnot.

basedon this schematic-

the power is that symbol labelled 3V on the far right above the ground symbol. Positive is at the top and negative goes to ground.

i think i understand now.. maybe.. :)

since the schematics were for one side of the two mics, this is how itd look for both mics right?

i did some crude editing onto the schematic.. is this right? does ALL the grounds go to the neg end of the power? o_O
