Can I done it by cascading just 2 similar configs I showed in my first post?
The opamps in your first post have no reference voltage (0V) on the pin 3 input of the opamps so they do not work.
I don't know what is the DC voltage at the output of your powered electret mics.
If you cascade two opamps that each have a gain of 101 then the total gain is 10,201 which is much too high.
If you cascade amplifiers each with a gain of 471 then the total gain is 221,841 which is ridiculous.
