Beginner’s Guide to Amplifier Class

Assuming you have been researching on the various amplifiers that are available for purchasing, you might have been overwhelmed by various classes on sale. You might have come across the amplifiers labeled class A, B, A/B, and D. You might have wondered, what the letter means. However, each class has pros and cons as below. caraudiohq.net

Class A

Pros

  • Clean output
  • Purer sound
  • Low distortion

Cons

  • Low efficiency
  • Larger size
  • High levels of heat generation

Class B

Pros

  • High efficiency
  • Less heat generated
  • Typically of small size

Cons

  • Signal distortion
  • Compromised reproduction sound

Class A/B

Pros

  • Clear sound
  • Better than class A

Cons

  • Low-efficiency level

Class D

Pros

  • Lightweight
  • Very efficient

Cons

  • Less clean output

Class A Amplifier

The unique feature of Class A is that it can conduct a complete cycle of a waveform. This means that it can replicate and amplify the maximum level while on at any time. Class A has a simple design compared to other classes. The main advantage of this class there is little distortion in relation to other amplifiers. Above all, they produce a good output. The good attributes it has makes it be highly rated. Additionally, this class amplifier is large compared to other classes. Generally, they occupy a big space.

Class B

This class of amplifier is a contrast to class A. It is configured in that the waveform is shared between two devices. Quite often, it is managed through pull or push configuration. This shows that the amplifier connects the current between two outputs. This means that they are more efficient compared to class A while using less energy. They occupy small space compared to class A.

Class A/B

This is the most popular or common class of amplifier that is easily found in car audio. This class is because of effort-combined strength. It minimizes the weakness of the two classes A and B. This is attained by letting each device output to overlap slightly, with regard to part of the wave they share. That means there are minimal chances for it to be off. The amplifier is mostly used for driving the speakers.

Class D

The most important or good thing about class D is the efficiency. It is rated above class A/B and class B. This results to an amplifier, which draws minimal power from your vehicle. There is little energy wasted compared to any other class. The configuration can be quite complex compared to other classes, this is because it operates in a very different way. It is very important to know that the D does not stand for digital. Many people sometimes mistakenly read that.

Conclusion

Typically, it is good to pair class A/B with component or coaxial speakers. Nevertheless, class D amplifiers are the best to power sub-woofers. Generally, it is important to buy the one that you can afford. You can visit your local store or consult the experts. However, sticking to the above classes you will be guided by purchasing the right one.
