How To Choose Between Class A, B, And C Amplifiers

In audio electronics, power amplifiers are characterized by the classifications of the amp which is then followed by the specifications and ratings. The class gives a general idea of the features and performance of an amplifier. The most common class, which we normally encounter is the "Class A" amplifier. This is also known as the solid state amplifier due to the fact that it operates on power semiconductor devices (solar or diodes) rather than power mains.

Class B (or class AB) is similar to the class A amplifier. However, the output signal does not have to pass through the device but rather is stored in an input circuit. As the name suggests, this class has limited power usage and typically amplifies lower frequency audio signals. So, if you want to make high frequency sounds, then the Class B amplifier will be your ideal choice.

Class C is an amp which uses single-ended or switched power supply. This class is ideal for lower frequency audio operation. In addition, it is capable of handling low power signals. Class D (or class Da) is the most popular amplifier among audiophiles and is used for professional audio applications. On the other hand, class E is ideal for powering many small appliances at the same time.

On the other hand, class C and class D are more energy-efficient than the class A. For instance, using a Class A amplifier for your home stereo unit while driving some high power devices at the same time can result in significant increased wattage consumption. Since it is only a single stage amplifier, you can save quite a lot of power especially if you have many devices to power. Thus, the class a amplifier allows you to get away with it and use a smaller amplifier.

Class D is usually used in studio recordings, where you need a bit more power to handle heavy equipment such as a drum kit. However, if you are into professional audio applications, you will find that using a Class D amplifier will actually save you power and energy. Its distortion output is also much quieter than Class A. Finally, if you do not need much power for all your devices, go for a Class B amplifier.

On the other hand, if you are looking for a class C amp, then you should get one that is capable of handling signal level levels that are above 100 volts. You can expect the amplifier's distortion level to be louder than allowed by the amplifier's specifications. Class D amplifiers on the other hand is designed to power lower signal levels and its distortion is kept at a minimum level. It also has a fast speed of buffering current and is known to have more power than Class A. So when looking for the best amplifier, you should consider the signal level capability of each of the class types.
