Briefly explain the difference between HIFI amplifier and AV amplifier

The power amplifier is called the power amplifier, which plays the role of the front and the back in the sound system - the front sound source, the rear speaker, the signal from the sound source is amplified, the sound is transmitted and the sound is released. In the HIFI system, the power amplifier is indispensable and is also a very important part, because the advantages and disadvantages of the power amplifier will directly determine the sound quality.

From the end use classification, the amplifier can be divided into HIFI, AV and karaoke amplifiers, but because the karaoke amplifier has been replaced by the AV amplifier with the rise of the home karaoke and the home theater, so here we will mainly Talk about the difference between HIFI amplifier and AV amplifier.

As a power amplifier that enthusiasts usually use, the design of HIFI power amplifier is to aim at high fidelity, and to pursue the delicate sound of sound quality, requiring a clear hierarchy. And most of them are mainly two channels, only left and right channel circuits. The AV amplifier is mainly to meet the needs of people watching movies, so the design requires audio and video integration. For example, Dolby Pro Logic decoders, AC-3, DTS decoders, and five-channel power amplifiers, which are popular in AV amplifiers, even have seven channels, which are not seen in HIFI amplifiers. From the perspective of listening, compared with HIFI amplifiers, the sound of AV amplifiers is very heavy. This is because it is caused by too many and complicated processing circuits in the signal circulation of the circuit. It is also for this reason that AV amplifiers are not taken by the majority of enthusiasts.

Seeing this, some friends may ask the old cat. In this case, why not design a product that is compatible with AV and HIFI. In fact, no one has done this, but most products are similar products or because of the dyeing nature of AV, not bought by HIFI enthusiasts; or because of the cost problem, the material selection is greatly limited, and the things that are made are not high. . Therefore, from a professional point of view, the old cat still recommends that everyone take what they want. Listen to music with HIFI amplifiers, watch large movies and choose AV amplifiers, each with their own duties, each without interference is the best.
