This Mini Microphone Preamplifier could be used as the first stage to amplify any audio signal. The device is equipped with a microphone plus clips to be connected to a 9V battery. Amplification is achieved by using an operational LM741 amplifier. The volume level could be adjusted via a trimmer.

This project comes in kit. Some components have to be soldered to the included PCB.
