“A preamplifier, often abbreviated as preamp, is an electronic device that amplifies a weak electrical signal to a level that is strong enough to be processed by another device, such as a power amplifier or a recording equipment. Preamplifiers are commonly used in audio systems, home theaters, and recording studios to boost the low-level signals from various audio sources, such as microphones, turntables, and musical instruments. By amplifying these weak signals, preamplifiers help to ensure that the audio signal remains clear and free from noise and distortion as it is passed through the rest of the audio system. In addition to amplifying the audio signal, preamplifiers often include features such as equalization, tone control, and volume adjustment, which allow users to fine-tune the sound to their liking.”
