Due to the development of society and economy, people pay more and more attention to the quality of life. Among them, the power amplifier is one of the necessary equipment for every family, especially for music enthusiasts, the power amplifier is even more essential. So what exactly is an amplifier? Let's walk into the world of power amplifiers and learn some knowledge about power amplifiers!

The power amplifier is referred to as the power amplifier, commonly known as the "amplifier", which is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source (in the professional audio system, it is from the mixer) to drive the speaker to make sound .

In fact, when it comes to power amplifiers, there are roughly three types: civil power amplifiers (HiFi power amplifiers and ordinary AV power amplifiers), special power amplifiers and professional power amplifiers.

HiFi, the abbreviation of High-Fidelity, that is, the meaning of high fidelity. It is the concept of complete listening, and it is all about bringing people the original high-quality music listening enjoyment. It is generally designed with two channels and has no display screen. The sound effect created by HiFi is positive, deep, and can well express the layering between people, solos and bands.

AV, the abbreviation of AudioVideo, which means audio, AV power amplifier is an amplifier specially designed for home theater use, generally has more than 4 channels and surround sound decoding function, and has a display screen. Its main purpose is to truly create the environmental sound effect of the film so that the audience can experience the theater effect. The sound effect created is surround. Although it is not as good as the HiFi sound in terms of imaging ability, it can be placed parallel to the monitor to create a grand scene. .

Professional power amplifiers are generally used for sound amplification in conferences, performances, halls, halls, venues and halls. The design is based on high output power, perfect protection circuit and good heat dissipation. Stereo power amplifier, the output power of each channel is more than 500W, which is larger than the output power of civilian power amplifiers, and the professional power amplifier is used in conjunction with the mixer when used, so the professional power amplifier does not have the input signal selection of AV machines, etc. Bass adjustment. Microphone amplification reverberation and other pre-circuits.

Therefore, when choosing a power amplifier, we might as well consider our own economic situation, personal requirements for sound quality and the occasion of use. But there are a few points that need attention.
