Note : Use a gain range of 20dB ~ 50dB in the amplifier section (40dB recommended).

Also, insert the capacitor between output and GND, instead of parallel to the gain setting feedback

resistor, in order to eliminate noise from the input.

Please note that use of the equipment under different conditions will cause vibration.
