![]() ![]() ![]() The latter contains biasing diodes that work on eliminating the characteristic distortion you get from Class B circuits. Class A/BĬlass A/B circuits combine Class A and Class B chains. However, Class B amplifiers are quite notorious for adding distortion to the signal. This leads to less wastage, resulting in greater efficiency (70%). Class BĬlass B amplifiers only conduct electricity about half the time. One benefit of Class A amplifiers is that they offer the greatest signal purity. This leads to a lot of electricity wastage because a relatively small amount of current will be drawn by speakers and the remaining will be converted to heat.Īs a result, the efficiency of Class A amplifiers is quite low at 30% and they tend to overheat with prolonged use. Here’s a brief overview of how efficiency varies between different classes of amplifiers: Class AĬlass-A circuits are set up in such a way that it causes amplifiers to conduct electricity 100% of the time. They’re differentiated by how their circuits work: particularly, how efficient they are.Įfficiency, in the context of amplifiers, is a measure of how much Alternating Current (AC) a unit can supply while consuming the least amount of Direct Current (DC). Amplifier ClassĪmplifiers mainly come in four different classes: A, B, A/B, and D. I’m going to be breaking each term down in a way that’s easy for anyone to understand. If you’re not too familiar with these terms, don’t worry. Hence, in this section, I’m going to be discussing a few of the technical details you should be paying attention to, including class, power output, impedance, speaker sensitivity, and frequency response. There are several factors you need to consider in order to ensure that the unit you buy fulfills your audio needs and perhaps more importantly, is compatible with your existing setup. Amplifier Buying Guideīuying an amplifier is not something that should be rushed. My reasons were simple: It offered all the power I needed (nothing more nothing less), featured a solid build, combined Class A/B and D circuitry and offered adjustable tone-shaping filters. After a ton of deliberation, however, I chose the Skar Audio RP-600.5 That’s not an easy question to answer, considering that each one of these amplifiers is nothing short of excellent. If I had to choose just my overall favorite from the top 5-channel amps, which one would it be?
