A microphone preamplifier, or mic preamp, is a device that boosts the low-level electrical signal produced by a microphone to a stronger signal that can be processed by other audio equipment. It amplifies the mic's signal to a level suitable for recording, mixing, or broadcasting. Preamplifiers are crucial for maintaining sound quality and ensuring that the audio signal is clear and strong before it is further processed or recorded. They come in various types and designs, including built-in preamps in audio interfaces and standalone units.
