Hi,
Without the input capacitor to that stage the passband gain is 150/4.75 which is around 32, but at 120Hz it gets cut by 0.7071 which brings it down around 22. Is that what you wanted?
If you want less gain in the passband then simply change the resistor value(s). The gain at the corner frequency (120Hz) will then be lower.
To check the gain at any frequency you can use this:
A=sqrt(((R9+R10)^2+w^2*C1^2*R10^2*R9^2)/(w^2*C1^2*R10^2*R9^2+R9^2))
but if you put the input cap back in we'll have to change that formula.
Without the input cap though the amplifier passes DC, something that you may or may not want to happen. The input cap blocks any DC inputs.
