For music enthusiasts, a good sound system can really bring you excellent auditory enjoyment. If you want to meet the music needs of a higher level, you must understand the difference between hifi and AV. Only after you know the difference between hifi and AV, can you really understand the sound system. Now let's introduce in detail the differences and characteristics between hifi and AV!
Definition of hifi and AV
hifi is the abbreviation of English high fidelity, which is directly translated as "high fidelity". Its definition is: playback sound highly similar to the original sound. So what kind of playback sound of audio equipment is hifi? So far, it is still difficult to draw a definite conclusion. Audio enthusiasts often judge whether the equipment reaches their hifi through their ears. Therefore, among audio enthusiasts, there is an endless saying on hifi.
When it comes to hifi, many friends think it is a leisure way to buy high-end enjoyment with money. In fact, this understanding is very wrong! The poor can also burn hifi. For real enthusiasts, hifi alone contains more than high fidelity sound playback. It also includes the adjustment of equipment, the acoustic treatment of harsh listening environment, the experience of playing with different equipment, and even the change results of the effects of discs in different systems. Further, there are the changes of positioning on sound and the impact of some gadgets on the system.
Generally speaking, the equipment with pictures and sound can be called AV equipment. For example, the most common TV and other systems can be called AV system. It is precisely because AV system has image output function, so in a strict sense, general audio equipment should not be regarded as AV system. However, in recent years, people's requirements for AV system not only stay on the surface of visual sensory stimulation, but also have more and more strict requirements for sound effect, And in recent years, pure sound has been unable to meet the pursuit of modern people, so we can only define a truly generalized AV system, which includes many concepts such as electricity, computer, satellite TV and network. Only when combined with a system can it be regarded as a truly generalized AV system.
The difference between hifi sound and AV sound
1、Price difference - from the price comparison between hi-fi equipment and AV equipment in the market, it is not difficult to find such an iron fact that AV home theater equipment is usually cheaper than hi fi equipment. From the perspective of audio consumers or enthusiasts, a high-priced hi fi power amplifier or a high-priced hi fi speaker, even at the sky high price level, is easy to be accepted or recognized by people or the market. Generally speaking, it has a good market because it is highly praised. Hi fi equipment with hundreds of thousands of yuan is common in the market. The materials used can also be described as heavy AV power amplifier, which is only 10000 or 20000 yuan on the market.
2、Sound field - the sound effect created by hifi speaker is in the front and has depth. Many people think that the speaker is parallel to the display and the back is only against the wall. However, such a sound field is flat and has no depth. Naturally, it has a poor sense of the position of characters and musical instruments. Where will there be a feeling of taking off the box. Two pairs of speakers, one on both sides of the computer and the other in front of the computer desk, about 50cm away from the computer screen, and the sound field falls on the computer screen, so as to reflect the sense of hierarchy of characters and bands. Friends who have put the bookshelf box on the tripod might as well try: move the box half a meter in front and listen to the sound about 1.5-2m away from the box to see what it feels like. If what you hear is still flat, Then your speaker or attack and play are not qualified enough.
The sound effect created by the AV speaker is surround, and its front sound field has no depth. Therefore, it can be seen that the position of the front speaker of the AV speaker is parallel to the display. The imaging power of this speaker is not as good as that of hifi speaker, because it can create a grand scene. In order to make up for it, a middle speaker is added to highlight the sound field of the characters and make up for the lack of intermediate imaging. In order to increase the momentum of the sound field, subwoofers are usually configured. Therefore, the gap between the sound field is the biggest gap between the two speakers.
3、Details and momentum - hifi speakers pay attention to music details, because when using hifi speakers to listen to music, they often drink tea and feel the music carefully. The better the speakers, the deeper the characteristics, skills and personality of the performers. Although some hifi speakers have good momentum in music, they are still worse than AV speakers, and the outstanding details will affect the momentum; AV speakers pay attention to the creation of character dialogue and grand scene momentum, because when using AV speakers to watch movies, they often feel the grandeur of the scene and the brilliance of dialogue with their families. Just a little of the scene, hifi speakers are not as good as AV speakers. In addition, when watching movies, they mainly focus on the picture and naturally ignore the details of the sound. The function of AV speakers is to set off the picture with grand sound effects, Naturally, the details are ignored. This is the difference between hifi speakers and AV speakers, which is the different ideas reflected in the design of these two speakers.
4、The difference between the quantity and quality of speakers - in terms of the quantity and quality requirements of speakers, AV sound is completely different from hi-fi speakers. AV sound is generally composed of several speakers, including satellite surround box and bass effect box. Compared with hi-fi speakers, these speakers pay more attention to the power, frequency response, distortion effect and other indicators of speakers. In addition to these, AV speakers pay more attention to the coordination effect between multiple speakers, while hi-fi speakers are completely opposite to AV audio. Hi-fi speakers are composed of two speakers. Both speakers have music restoration ability and sound effect, and do not have sound rendering ability, which can ensure the true replay of relatively high sound.
The sound of hifi speaker is clear. It pays attention to the taste of music and the quiet background and highlights the music. Therefore, it feels like clear water flowing through the heart, just like streams and lakes; The sound of AV speaker is atmospheric. It pays attention to the depiction of the picture and the construction of the scene. Therefore, it feels majestic, like a river and the sea.
