Microphone Preamplifier – Sound Sensor
This is an easy to construct dual-stage microphone pre-amplifier. The project can be used as a sound sensor or microphone pre-amplifier. The 1st op-amp pre-amplify the very low-level signal coming from the condenser microphone and 2nd op-amp provides more boost to the audio signal....
