Amplifiers are among the top investments today at home with their ability to improve audio output.  They come in different sizes with many offered in home theater packages. Due to the options available, finding the right audio amplifier for your home can be challenging. Get to know more about amplifiers with an array of information.

What is an Amplifier?

An amplifier, amp for short, is an electronic device used for improving sound output with the help of electric supply. They utilize electricity to improve audio signals, giving it a crisp and loud sound ideal for superior home theater experience. Depending on the type, an amp is connected to components or musical instruments to produce the sound that many people wanted to achieve for their homes. It can be classified in different classes and types depending on the amount of electricity used for operation. One of the crucial things to check out in finding the best amplifier is ensuring that it’s the right one for your preferred use.

Amplifier Classes for Home Use

There are different types of amplifiers available for home use. As of today, there are five main home amplifier classes currently available in the market. You must know these types first before actually getting into one for your home.

Class A

Class A amplifiers use the most energy to amplify audio output. Since this class consumes a lot of energy, it’s not the best choice for those who are concerned with the electric bills. However, Class A power amplifiers are the best choice for those who are after perfectly reproduced sound output.

In buying this class, buyers must be prepared with the temperature produced for sound reproduction. This is normal and homeowners should not worry about it too much when used.

Class A/B

As its name implies, this class is a combination of Class A and Class B amplifiers, ensuring consumers to experience both types’ best features. This class is probably the best choice for consumers who want to get the same quality output produced by Class A amplifiers while taking advantage of Class B’s energy efficient feature. But even with the sound quality, it’s sound reproduction mode is considered lower than actual Class A amplifiers, which many hardcore Class A fans may not appreciate. Most amplifiers sold as consumer electronics today are under this class.

Class D

Class D amplifiers are also very efficient. Its capable of switching its output devices per cycle unlike other types. People often refer to this type as digital amplifiers, but the truth is not all Class D amps are digital amps. Since it can easily change its mode, a Class D amp will use less electricity, saving up to 80 to 90 percent of energy use. Due to its popularity, manufacturers are coming up with new enhancements that improve its performance by a mile.

If there’s one thing that amplifier enthusiasts won’t appreciate is its rapid frequency changes and harmonic distortion.

Class G and H

Both classes are discussed together because of their capability to improve voltage depending on the sound it needs to amplify. The difference lies on the type of audio signals they change. Class G works on output, giving it extra power when needed. Class H, on the other hand, focuses on the input then switches voltage if necessary. Just like other classes, Class G and H’s ability to adjust power use according to what the signal demands make them more energy efficient than Class A.

Shopping Tips

Due to the demand, manufacturers began to produce more amplifiers to distribute to potential customers. You’ll have many options to choose from, which increases your chances of finding the right product for you. However, this can also be problematic if shoppers don’t know which to choose.
