Listening to a vinyl record has been a very sophisticated listening style. People who come to this form of music are usually very delicate.

The sound of vinyl record is very different from the popular digital audio now. While the digital sound is somewhat magical, it is easy to adjust the sound, the pitch of the singer, the sound of the vinyl record has its own charm. When listening to a good performance of a vinyl record, people hear stereo sound, as if you are listening to live orchestra playing, the position of the instruments in the orchestra, the vocalist’s real and inspiring voice. Therefore, in the world in general, there is still a difficult part of listeners, especially love, collect and enjoy vinyl record. Special music that fit vinyl record like Jazz – Blue, classical music or Acoustic instruments.

The vinyl record has a three-piece structure: the reader or phonocatridge, the mechanical part or the tonearm, the turntable part is the rotary wheel and the motor. There are two types of common readers: “dynamic magnet” or MM needle (Moving Magnet). The second type is called “Dynamic Coil” or MC needle (Moving Coil). The cheaper MM is very popular, the MC gives better sound quality than the MM type, most expensive readers are now MC types.

Perhaps the vinyl record player, besides enjoying the sound of it, also requires the character of the person to be careful, sophisticated and must have ears for music. For vinyl record players, besides the main investment is buying gramophone, sound, speaker, vinyl record … players also have to invest in spare parts such as compressed air dust guns, carbon brushes to sweep dust on coal plates. (For example, an $ 15 AudioQuest brush), antistatic spray (such as $ 50 Allsop Orbitrac 2 disk cleaner), special brush and solution to clean the needle tip of the record. Coal discs must be stored carefully in a glass cabinet to avoid dust, environmental humidity or high temperatures, causing the disc to explode or warp

While the digital world is growing strongly, vinyl LP continues to be collected with stable production levels, perhaps due to their warm, natural analog sound. So, how can LP achieve such unique sound qualities!

In 1877, Thomas Edison was considered the inventor of a phonograph, the first device that could both record and playback sound. This device records the sound bar directly when the dimples on the foil wrap around a grooved roll, which is then played back by rotating the roller, following the movement of the needle along the lines. That groove, vibrates the corresponding mechanical diaphragm and reproduces sound. By the 1880s, Volta invented a wax-coated cardboard cylinder using vibrations of gramophone needles, like a seismograph, called the “hill-and-dale” method, like Edison’s. . Until the beginning of the 20th century, the cylinder was finally replaced by the flat disc recordings that we use today. But even then, the sound is recorded directly on the disk mechanically. Such “acoustical” recordings are based on a large audio device connected to a gramophone needle. When the sound waves that cause vibration will vibrate the needle, and put those vibrations into the hand-cranked disc.

The problem is that the amplitude of the low notes (bass notes) is many times higher than the notes with a higher pitch, the lower-frequency sound occupies more physical distance in each segment, then , high and medium sound bands will be lost during playback. This makes the sound distorted as well as heavy bass. It was not until 1925 that audio inputs were run through a microchip and an amp to increase the range as well as volume without depending on the physical properties of the audio equipment, and the era. The “electrical” records have started. These recordings are deliberately adjusted for high sound bands and low bass, making the sound balanced during playback. 78s – recordable discs with rotational speed of 78 RPM- are seen as a technological leap compared to predecessors.
