The job of a microphone preamplifier is to boost microphone level signals to line level so that the signal can be converted from analog to digital. This mic to line boost is generally a preamplification of over 400 times the voltage of the original mic level signal. This preamplification stage is one of the most important stages that the signal will go through before converted to digital, and is why a high performance preamplifier is important to achieving great results.
