Use the "zoom" or magnification feature of your PDF reader to see the resistor and capacitor values. The high pass filter is first order, the low pass filter is second order.

Interesting chip. What made you decide to use it?

I have a similar project in progress using a different op amp. I'm making mine variable gain. When I have a gain value I will try to post it here.

how much gain would you recommend using for the Lm833 preamp?
The gain that is in the circuit provided.

You see, without knowing what kind of microphone or what your final output goals are, we can't guess how much gain. Apparently you can't either. Just build the obvious one and if it sucks, at least we have a starting point.

"Interesting chip"
Yeah. They are so old that mold has grown on the ones I have.
