Boston Acoustics, Inc. Datasheets for Audio Amplifiers and Preamplifiers

Audio amplifiers and audio preamplifiers are used to increase the amplitude of sound signals.  Preamplifiers or preamps are designed to amplify low-level signal from a high-impedance device such as a microphone or instrument pick-up. After pre-amplification, the signal is sent to a power amplifier or amp, which provides the higher current necessary to drive the speakers.
