Power amplifiers are usually a crucial link in between your audio gear and your loudspeakers. Should you be curious about finding out more concerning how stereo amps function, keep reading the following few sections. I will explain the function of sound amps plus show a pair of handy tips pertaining to hooking up amps to a pair of loudspeakers.
An audio amplifier is going to take a relatively low-level music signal and boost it sufficiently in order to drive your speaker and in addition convert the impedance of the signal. Your amplifier is vital because if you were to attach your source directly to your speakers, not only would you be doing damage to the source but in addition, the power level which the source can deliver to your speakers is actually really small.
Nearly all stereo amps these days are made with a "Class-D" topology. Class-D stereo amps excel by giving extremely high energy performance. So a lot of the energy that is being taken in by the amplifier is transformed into useful wattage and then provided to your speaker. Subsequently you may save some cash on energy when acquiring a Class-D amplifier. Because merely a tiny fraction of the energy taken in by the amp is dissipated as heat, you'll find some pretty small audio amplifiers in the marketplace that employ the Class-D topology. The amplifier enclosure is commonly adequate in order to allow sufficient radiation of heat.
Should you be an audiophile and need the greatest sound quality then Class-D amplifiers may not be your best choice. That is because Class-D amps employ a digital power stage along with modulators. These kinds of elements may result in some amount of audio distortion. Similarly to Class-D amps, tube amps also generate a fair level of distortion. Even so, tube amps remain rather popular amongst audiophiles. Some people have a preference for stereo amps which contribute to a certain amount of distortion so long as the higher harmonic signal components display a consistent decrease with larger frequencies.
Analogue amplifiers, however, utilize a totally different technology. The audio signal is magnified in the analog domain. Subsequently, analogue amps including Class-AB music amplifiers in most cases have lower music distortion in comparison with switching amplifiers. The main disadvantage of analogue stereo amplifiers when compared to switching amps is the small energy efficiency. Because analog power amps dissipate a large amount of energy as heat, there has to be a few device for the heat to radiate. This is usually achieved with an electrical fan. Yet another choice is to use heat sinks. These heat sinks typically make the amp relatively large.
Be cautious about what sort of speaker you attach to your amp since loudspeakers having quite low impedance may do some serious harm to your amp. In addition, stay away from attaching speakers having an impedance that is significantly higher than the largest rated impedance considering that you will not get as much wattage from the amplifier in that case.
