Is the AV misunderstanding independent amplifier better than the combination audio amplifier?

One of the simplest sound systems, including sound sources, amplifiers and speakers, is indispensable. The quality of these pieces of equipment basically determines the quality of the entire system. Among them, the power amplifier as the power of the sound system plays a role as a bridge between the sound source and the speaker. The working principle of the power amplifier is actually very simple. Intuitively, it is to amplify various sound signals played by the sound source to promote the sound of the speaker. From a technical point of view, a power amplifier is like a current modulator, which converts alternating current into direct current, and then is controlled by the sound signal played by the sound source, and transmits different currents to the speaker according to different frequencies, so that the speaker emits corresponding size. The sound of the corresponding frequency. Due to consideration of power, impedance, distortion, dynamics, and different range of use and control adjustment functions, different power amplifiers have different internal signal processing, circuit design, and production processes. Traditional amps have experienced 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 video software, many audio manufacturers have referenced the real cinema on the basis of traditional power amplifiers. The characteristics of sound playback, design and production of a variety of different types of technical characteristics of the integrated power amplifier, people call it AV power amplifier.

AV power amplifier is an independent video and audio control equipment formed on the basis of traditional power amplifiers with the development of video playback equipment and software. Generally, it includes a power amplifier part and a signal control processing part. The principle of the power amplifier is no different from the traditional power amplifier, except that several channels are added, that is, several power amplifiers are combined; the signal control processing part involves signal sound, video selection, signal decoding processing, and signal. Sound field processing and functions such as radio and monitoring. It can be seen that compared with the traditional power amplifier, the AV power amplifier has undergone a qualitative change in function, so strictly speaking, most AV power amplifiers should be called AV centers. The formation of the AV center meets the requirements of modern home theaters for the playback, display and processing of audio and video in a variety of media. It is indeed more in line with people's needs for entertainment and appreciation, but also precisely because it is a "center with multiple functions." ", so it is not easy to achieve a high level of performance in various parts, especially in the AV center's power amplifier part, the sound quality of most products is not satisfactory, perhaps this is where the AV amplifier needs to be improved.

As a power amplifier for AV, its channel power setting, the quality of the signal decoding processing portion, and the musical expression, sound quality, and convenience of operation as music enjoyment can all reflect its performance to some extent. Generally, a high-quality AV power amplifier should first have a better sound field reduction in the signal processing of the film and television program, the channel isolation is high, and the atmosphere rendering can not be too exaggerated; secondly, the sound quality performance of the power amplifier part, especially the main The sound quality of the channel should be as close as possible to a better pure music amplifier. Of course, the positioning of the AV amplifier is different from the pure music amplifier, and it is impossible to unrealistically demand how high the sound quality is.

Since the promotion of home theater equipment has been very popular by some media and merchants, many consumers who have just started to introduce audio have gradually formed a power amplifier that should have multi-channel, surround sound and other functions. The standard, this can not be said to be a misunderstanding. Hi-Fi equipment with better performance on music has almost no market, which makes it difficult for many people who like music to find high-quality pure music amplifiers. This phenomenon is really regrettable. Practically speaking, due to different specificities, home theater and pure music audio systems should be able to coexist, and home theaters do have their advantages in meeting the general entertainment requirements of most people, but if it is called 2, 3 thousand yuan 7 sets of even more than 10,000 yuan can be set to maintain the momentum of a full set of home theaters, it will not only lead to a more unfavorable situation of pure music audio in a certain period of time, but also home theater is bound to take the old road of combined audio.
