Preamps Preamps (short for "pre-amplifiers") are an important part of any audio production.
Preamps are used to amplify the weak electrical signal coming from a microphone, instrument or other sound source before the signal is sent to a sound card, mixer or other devices in the audio chain.
In addition to amplifying the signal, the preamp can also enhance and color the sound of the microphone or instrument in a specific direction.
Preamps come in different flavors and functions and play an important role in audio production.
