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.
Connect the microphone cable to the microphone. Connect the opposite end of the cable to the microphone input on the preamp.
Connect the preamp's output to the microphone input on the computer with the stereo audio cable.
Turn up the computer's microphone volume three-quarters of the way up. Make sure to disable any microphone boost or additional special effects.
Adjust settings on the preamp to the desired sound and volume.
