Hi-Fi audio knowledge

                                                       Hi-Fi audio knowledge

Hi-Fi is the abbreviation of High-Fidelity in English, translated as "high fidelity", its definition is: a replay sound that is highly similar to the original sound.

To evaluate whether a sound system or equipment meets the high-fidelity requirements, it should generally be carried out by combining subjective listening evaluation and objective index test, and the objective test index is the main basis. Because using instruments to test the performance indicators of equipment can obtain very intuitive quantitative results for reference and comparison, it is undoubtedly the most scientific and trustworthy.

British sound, "American sound", Danish sound and "German sound" are popular in the audio industry

The first, but the current technology can only be a relative definition of faithful reproduction, which is one of the reasons why speakers of different brands have their own sound characteristics.

Furthermore, a mature brand will have its own preferred style. It will design a style that it thinks is satisfactory for all its models or a series of models, and calibrate its sound in this direction. Especially the speaker is the most distorted link in the audio system. A popular saying among speaker designers is: It is easy to flatten the spectrum, but it is not easy to make your own style. In the final analysis, it is the distortion of the speaker, which can not only give style, but also give the designer's musical accomplishment.

Cultural regional imprints behind sound styles

Regarding the understanding of style, different cultural regions have different understandings, so there are "British voice", "German voice" and "American voice". This "XX sound" represents a cultural understanding of sound. This understanding is not at the technical level, but at the artistic level. Behind it is the precipitation of culture and the character of the nation. Unfortunately, there has never been a "Chinese voice". It's not that China has no culture, but that Chinese practitioners and consumers have abandoned Chinese culture. There are only a handful of domestic brands that have formed their own style. Many of them design whatever style is popular, which has obvious profit-seeking nature, and more of them don’t understand what style is at all, and those that can make a sound are regarded as products. .

Detailed explanation of various sound styles:

british sound

The British upper class pursues a meticulous and elegant atmosphere. The male guests should be like gentlemen, and the female guests should be like ladies. They should not be overjoyed about things, be calm and calm, pay attention to some small sentiments, listen to some small-made music or even solo, the sound It doesn't need to be huge, let alone bursting, as long as you can hear clearly. On the whole, it is a slow-paced and meticulous life. Their unanimous approval of this kind of life makes them like a kind of music with prominent mid-frequency, low low frequency and bright high frequency, which is softer, slower and slightly warmer. Style, the soundstage is small but not tight, and the details are rich but not outstanding. This sound orientation has been recognized by almost all British audio equipment manufacturers. Although there are differences in the sound characteristics of their products, the basic features are similar. This typical stylized feature is called "British sound". The British voice varies greatly according to the sound style of the era. Old-school British sound refers to the traditional sound style of the early British audio, with dim tones, rich timbre, and prominent mid-frequency. The new style of British sound has good extension at both ends, overall analysis and transparency, but maintains the delicate, gentle, elegant and modern British style of traditional British sound with good mid-frequency density. Generally speaking, British Acoustics does not pursue hard indicators such as widening frequency response, dynamic range, powerful strength, sense of speed, transients, etc., but pays more attention to timbre, so most British acoustics equipment is not expensive, and there are many audiophiles among the majority of audiophiles. High retention.

british sound

British-style equipment that mainly expresses symphonic music, commonly known as "British sound".

Typical representatives are speakers of British brands such as BW, TANHLOY (Tianlang), MISSON (Bel Canto), KEF (Kraft), PKOAC (noble), Rogers (Jazz). This kind of speaker has a soft, delicate and warm sound, excellent mid-high frequency performance, flexible sound, rich sense of music, quite aristocratic gentlemanly demeanor, and long-term close listening will not feel tired, especially suitable for listening to classical music, symphony, light music and Artistic works such as bel canto songs. However, the dynamics of British speakers is not as large as that of American speakers, the instantaneous response is slow, and the efficiency is relatively low; for example, the famous British speaker classic LS3/5a is only 82.5dB, and the driving power of the power amplifier must be sufficient to fully develop its potential. .
