In a Hi-Fi components system the amplifier is perhaps the most important part. Without this there would be no sound. The first amplifiers used valves, also called vacuum tubes, to amplify the sound but this was replaced in the 1960s and 1970s by electronic transistors. The function of an amplifier is to take a weak input signal and increase its power for a specific purpose. In audio, this purpose is to drive the speakers and produce sound. Amplifiers are rated in Watts. Each channel is given the same wattage so a stereo amplifier will be designated 20x2 watts and a car amplifier typically 20x4 watts. Each channel represents one speaker. Incidentally, 20 Watts is usually more than enough to create ear shattering sound. Just like in speakers however, amplifiers can be rated misleadingly. The power output is measured by a sine wave, this looks like a hill and so has a high point and both ends touching zero. To take the peak measurement would give a less accurate representation of what the amplifier is capable of than by taking an average across the wave. The average sound output is given as the RMS value. Generally Hi-Fi equipments will give its power as RMS but an amplifier intended for the home market will concentrate on Peak Music Power Output. A good amplifier will not exhibit too much flutter or distortion but will be expensive. There are also a number of Hi-Fi amplifiers that still use vacuum tubes. Audiophiles claim this gives a richer sound.
