Boosting the volume on a microphone is a good way to strengthen its recording power. No matter how great a computer's recording software or microphone input, the strength of a microphone is severely limited, and in the case of a dynamic or condenser microphone, it is not a possible to boost its signal without other equipment. Because of these limitations, the use of a preamp is required. A microphone preamp enhances the signal to and from the microphone, allowing a higher overall volume.
