What is a Preamplifier?
A preamplifier is an amplifying electronic circuit which can be connected to a low output level device such as a phono cartridge or a microphone, and produce a larger electrical voltage at a lower impedance, with the correct frequency response. Phono cartridges need both amplification and frequency response equalization. Microphones only need amplification. In most audio applications, the term ‘preamplifier’ is actually a misnomer and refers to a device more properly called a ‘control amplifier’. Its purpose is to provide features such as input selection, level control, tape loops, and sometimes, a minimal amount of line-stage gain. These units are not preamplifiers in the most technical sense of the word, yet everyone calls them that.
