So what kind of audio equipment's playback sound is HI-FI? So far it is still difficult to make a definite conclusion. Professionals in the audio industry rely on various instruments and various means to detect various indicators to determine the degree of HI-FI equipment, while audio enthusiasts often use their own ears to judge whether the equipment meets the HI-FI in their minds. . To judge the high-fidelity level of the playback sound, not only high-performance equipment and software are required, but also a good listening environment. Therefore, there is still a difference between objective testing and subjective evaluation on how to correctly measure the HI-FI level of audio equipment.

Strictly speaking, as long as we can see the image and hear the sound, we can call this scene AV. Literally speaking, the meaning of AV is the combination of the first letters of the English words AUDIO (audio signal) and VIDEO (video signal). Write, HIFI means "high fidelity". Picture The difference between AV audio and HI-FI audio is not something that every ordinary consumer can distinguish. Here we will briefly talk about the difference between AV audio and HI-FI audio. First of all, in terms of price, the price of AV audio and It is an indisputable fact that the price of HI-FI speakers varies greatly. The price of a set of mid-to-high-end AV speakers can often only buy a set of entry-level HI-FI systems, so the price is the difference between AV speakers and HI-FI speakers. An important distinction. Secondly, in terms of the quantity and quality requirements of the speakers, the requirements of AV speakers and HI-FI speakers are completely different. AV speakers are generally composed of several speakers, and these speakers include satellite surround boxes and subwoofer boxes. Compared with HI-FI speakers, it pays more attention to the speaker's power, frequency response, distortion effect requirements and other indicators. In addition to these, AV speakers pay more attention to the synergistic effect between multiple speakers, while HI-FI speakers are completely compatible with AV speakers. On the contrary, HI-FI speakers are composed of two speakers, both of which have music restoration ability and effect, but do not have sound rendering ability, which can ensure the real playback of relatively high sound. Of course, with people's different requirements for sound effects, AV speakers and HI-FI speakers are developing in the same direction. During the year, we may see more combinations of AV&HI-FI speakers.

Chinese HI-FI

The introduction of the term HI-FI to Chinese audio should have been in the early 1980s. The rapid evolution of the tape recorder. Strictly speaking, however, the first monophonic combined audio set is still not a HI-FI audio, and the domestic two-channel stereo combined audio should not be included in the real HI-FI audio.

The real rise of China's HI-FI audio should be the moment when the combined audio system transitions to the personalized audio combination, that is, the audio source, power amplifier, and speakers appear as independent single pieces, and personalized matching is carried out by enthusiasts. At this time, many audio companies in the Pearl River Delta of Guangdong, China launched their own single-piece HI-FI equipment. Although it is very common today, it should be attributed to the most basic HI-FI entry-level products back then.
