Early the next morning, Hong Tao hung one arm, held the handlebar with one hand, and came to Jishuitan Hospital slowly, and said that his behavior of going into the water to pick up the bag last night was a righteous and courageous act. Pen, fun, pavilion www. biquge。 Info Then under the doctor's suspicious eyes, he changed the plaster cast that had been soaked in water again, and told him that the wound was not wet and recovered well, so he left the hospital satisfied, did not even ride a bicycle, and walked along the alley to the west of the hospital to Xinjiekou.

Xinjiekou is a commercial area in 96, but it is not famous for the Xinjiekou shopping mall and the string of specialty stores on the street, but the sound city located on the west side of the Xinjiekou T-junction on the north side of the road, the ultrasound on the south of the road, and the popular art video store next to the Xinhua bookstore and a large number of audio equipment and lighting equipment stores such as Huimin, famous products, Kaiyun and so on gathered around them.

Kyoto people like to get together for everything, to play antiques have to go to Liulichang Panjiayuan, to save a computer to go to Zhongguancun, to have a meal across half of the city also have to run to Gui Street, which does not even have a parking space, to play with a bird and buy a fishing gear or something, then go to the Guanyuan flower, bird, fish and insect market. If you are interested in audio equipment, then come to Xinjiekou. There are not only professional stage lighting and sound here, but also audiophiles like HIFI audio, genuine discs, pirated discs, bakelite records, mouthbands and mouthpieces are also a lot, this is not the kind of disc sold by women holding children in Zhongguancun, nor is it used for computers, but audio products with music, songs, and movies as the main content.

Further south of the Ping'an-ri intersection, there are two large shopping malls focusing on electronic components, anyway, they are all related to audio equipment, if you can't find the equipment and music materials here, there is no other place to turn around in Kyoto.

Hifi is the abbreviation of high-fidelity, which translates to a high degree of fidelity according to the meaning, and when used in audio equipment, the expression equipment has a very high degree of restoration of music. In fact, this concept has no meaning for ordinary people, and it is only useful for a small number of people who are very obsessed with music, very obsessed with audio equipment, and have a very detailed understanding of both.

The tapes, laser records, bakelite records, etc. that we usually listen to are called sound sources, that is, the recording carrier of sound, and only through the sound materials recorded on these carriers can the sound equipment be made, not randomly, but according to the details on the material. In this way, the amount of material and the ability of audio equipment to restore the material into sound have become two very important indicators.

For example, in a symphony concert, most people can't listen to it live, and can only rely on cassette tapes, laser records, and bakelite records to be immersive. In addition to a very good record, you also need to have a set of high-fidelity audio equipment to really be able to hear every part, every harmony, and even every flawed murmur of the orchestra as if you were there. Of course, ordinary people can't hear it, and only a small number of people can reach this level, and this small number of people are called audiophiles. They are not only interested in music and research, but also very picky about sound equipment.

That's right, that's the case, most of the audio equipment, including your TV, stereo, home theater system, as well as cinemas, gymnasiums, and concert venues, are not high-fidelity, and they more or less have to change the sound elements in the sound source to achieve the desired effect.

The purpose of most audio equipment production is not to let a small number of audiophiles test their very picky ears, but to amplify, amplify, strengthen the decibel and sound pressure level, in order to meet the listening needs of most ordinary people, so a part of the restoration function will be abandoned, and some sound elements will be lost in the process of work, and only the most important part will be retained.

Who cares about whether the violin sound in a piece of music should be on the left or the right? Is the finishing note of the clarinet clean? To put it mildly, who can hear these flaws in most people? If they can hear it, it is already an audiophile-level ear and musical literacy. So for most people, these sound details are not needed.

When these electronic devices are manufactured, the characteristics of the semiconductor components and the speaker cone material also make it easy for these details to be lost in the amplification process, or not easily represented. Through the special treatment of the amplification equipment, this part of the loss can be minimized, which is the purpose of hi-fi audio equipment.

As some of them got rich first and had spare money in their hands, they began to pursue a higher quality of life, so the group of audiophiles slowly emerged in China in the mid-90s. But to be honest, at least 80 percent of these people are in vain, and in today's terms, they are pretending. They don't have the musical literacy and in-depth study of electronic devices that audiophiles should have, and the reason why they pursue these high-fidelity equipment is for only one purpose, just like having to get a bookshelf at home and then put on a variety of world classics, which is used to show their identity.

And HIFI equipment has slowly become a kind of rotten street standard with the needs of these people. Just buy a headphone, which also has the word HIFI written on it, and buy a theater system at home with HIFI printed on it, as if everyone is an audiophile. This is all a promotional method adopted by merchants to take advantage of people's ignorance, and it seems that it is not advanced enough without printing this technical term.

In fact, hi-fi is not suitable for most people, because its dynamic range is not large enough, the cost is very high, and it is very inconvenient to use. Let's take the simplest example, let's say you buy a movie disc and use a set of hi-fi as a sound reinforcement device, and the end result is definitely not as good as a home theater system.

The reason is very simple, hi-fi is not used to play movies at all, nor is it used to play Di Qu, let alone sing karaoke, and the field suitable for it is very narrow and very literary. It's like a professional F1 car, it's fast, right? It's faster than an ordinary car, but who can drive it? Out of the field, without a professional racing driver, without a logistics maintenance team, it's just a waste, not to mention the problem of the traffic police not letting you go on the road.

Hong Tao has not studied this part of HIFI speakers, and he is not an audiophile, not even a low-grade fever. The audio equipment he likes can be said to be completely opposite to the HIFI sound, this part is called the professional stage sound system, that is, the set of equipment used when we go to the concert. This kind of audio equipment does not pursue the restoration of musical details, but works large dynamics, high power, and sound pressure levels, and there will be a special vocal processing system, multi-channel mixed mixing equipment, and strive to bring people a shocking feeling, the treble penetrates the sky, and the bass is tough and powerful.

This kind of device can't be used in a small space, there is not enough distance, if you sit two or three meters in front of the speaker and listen, the treble will make you dizzy, the bass will be muffled, except for noisy, there is no beauty at all. This design is designed to meet the needs of tens of thousands of ears on the scene, so that the sound pressure level in every corner is about the same, whether you are standing in the front row or the back row, you have to hear the rhythm and vocals clearly, otherwise I'm sorry for the admission ticket you paid for.

If HIFI audio is a fine, elegant, expensive, and squeamish F1 car, then professional stage audio is a strong, burly, and powerful truck, and Hong Tao is the driver of this truck, and now what he has to do is to familiarize himself with the performance of the truck he is about to drive.
