The Amplifier and Its Place in the High-Fidelity System
In the high-fidelity system, the amplifier is the single coordinating element which makes possible the correct function of all other elements. The reproduction of sound is not new, but the early phonographs provided only a mere travesty of the original music. In these crude units, the actual energy with which the record vibrated the needle in turn actuated the diaphragm which drove the horn. Thus the actual sound energy radiated by the horn was derived directly from the vibration of the stylus by the record with no amplification. For recording, a similar system operated in the opposite direction.
