The principle of sound reinforcement of audio power amplifier is actually very simple. The simplest audio system has audio source, power amplifier and speakers, all of which are indispensable. The quality of these pieces of equipment determines the quality of the entire system. In addition, as the power of the sound system, the power amplifier acts as a bridge between the sound source and the speakers.
To put it directly, it is to amplify the various sound signals played by the audio source to drive the speakers to emit sound. From a technical point of view, the power amplifier is like a current modulator. It converts alternating current to direct current, and then is controlled by the sound signal played by the sound source, and transmits different sizes of current to the speakers according to different frequencies, so that the speakers emit corresponding sizes. , The sound of the corresponding frequency.
Due to consideration of power, impedance, distortion, dynamics, and different use ranges and control adjustment functions, different entertainment audio systems and amplifiers have different internal signal processing, circuit design, and production processes.
Traditional power amplifiers have gone through decades of development, and there has been no special classification. Until recent years, with the development of audio and video playback equipment and the richness of film and television software, many audio manufacturers have made reference to the real movie theaters on the basis of traditional power amplifiers. With sound playback characteristics, comprehensive power amplifiers with different types and different technical characteristics have been designed and produced.
