    A turntable amplifier is a device that changes, by usually increasing, the amplitude of a signal. The relationship of the input to the output of an amplifier—usually expressed as a function of the input frequency—is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain. The point of the amplifier is to bring the audio signal to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain. The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification, equalization, tone control, mixing/effects, or audio sources like record players, CD players, and cassette players. Most audio amplifiers require these low-level inputs to adhere to line levels.
    There are many companies that manufacture record player amplifiers of varying qualities, including Audio Tekne, The Bluenote s.r.l., Witchdoctor Audio, Opera Audio, Behringer, Audio Technologies Inc., and Allnic to name just a few.
