Hello, music lovers! Today we will talk about one of the most controversial terms in sound.
In the minds of people for a long time, Hi-Fi was presented as expensive acoustics for geeks from the world of music “audiophiles”, to listen to which you need to have a good musical ear, and the “ordinary” user will not hear the difference. Such equipment can be easily purchased in a variety of stores. Hi-Fi has become quite massive and is gradually capturing the hearts (and ears) of people.

The expression “high fidelity”, which in the future was shortened to “Hi-Fi”, was first used in 1932 by the English engineer Harold Hartley to advertise his outdoor loudspeakers. High fidelity translates as “high fidelity”, which very accurately conveys the meaning of Hi-Fi audio. The issue of quality and accurate reproduction of the recording has interested people for a long time, for example, in the XIX century, the recording was considered high-quality if the dog could recognize the owner’s voice.


Thanks to such a test, one of the famous record companies made a dog sitting next to a gramophone its logo. Let’s start with the story. As you know, an important event in the world of sound recording was the invention of the phonograph by Thomas Edison back in 1877. Now, in order to listen to music at home, it was not necessary to hire musicians or learn to play yourself.

In the 60-70s, the equipment for home sound recording was greatly improved and became available to a wide audience. It was at this time that Hi-Fi manufacturers had a need to separate “good” and “Hi-Fi” equipment, in 1974 the German Deutsches Institut für Normung (DIN) issued the DIN 45500 standard defining standard requirements for sound reproducing equipment.

Then, according to this standard, they measured:
The maximum values of the unevenness of the amplitude-frequency characteristics of the sound reproducing equipment;
Nonlinear distortion coefficient or harmonic coefficient;
Noise level the ratio of the useful signal to the level of its own noise.

The methods of measuring these and other indicators will now be determined by the current DIN 45500 standard.

What is the difference between Hi-Fi and "not Hi-Fi"

Hi-Fi equipment allows you to feel like a participant in a concert of your favorite artist, to be in the center of the events of the film, to hear in your recordings what you could not hear before because of the parameters of the acoustic system. Hi-Fi sound quality and the Hi-Fi sound itself are beautiful and delightful.

As practice shows, once a person listens to audio recordings on high-quality Hi-Fi equipment, they no longer want to return to ordinary plastic speakers. But the main thing is the feeling.

There are various Hi Fi speakers:

– Hi-Fi home speakers
– Hi-Fi home theater system
– Hi-Fi speaker
– Hi-Fi portable speaker
– Hi-Fi portable speakers
– Bluetooth Hi-Fi speakers
– Hi-Fi stereo speakers
– Hi-Fi stereo system
– outdoor Hi-Fi speakers

Hi-Fi doesn’t just transmit sound, it conveys sensations, it conveys musical taste and juiciness. If you close your eyes, you can clearly imagine the entire music scene of the recording that the vocalist is standing slightly to the left of the center, and the bass guitarist is in the back. If the car in the cinema will be removed into the sunset, the sound of its engine will be removed, and not fade away.

These are not a number of characteristics, this is not expensive equipment for the elite, Hi-Fi is a new experience that you can feel thanks to the high fidelity of sound transmission and approach to the creation of acoustic systems and other audio components.

Will a person who is not experienced in sound be able to hear it? Definitely can.

Channel 2.0

A 2-channel Hi-Fi stereo system creates a surround sound effect. Many music lovers prefer just such acoustics when the instruments sound so realistic.


Simple, fast, flexible: Use Bluetooth technology to wirelessly connect a Hi-Fi audio device to other devices, such as a smartphone or tablet. Now you have even more options.

Equalizer Presets (EQ)

Thanks to the pre-settings of the equalizer, you can choose the optimal sound mode depending on your preferred music or playback style.

Remote control
Turn it on or off, quietly or loudly easily control the Hi-Fi audio device using the remote control. To do this, you do not even need to get up from a comfortable sofa.

Wooden speaker housings
As a natural material, wood gives a number of advantages to Hi-Fi dynamics. Firstly, it outputs rich and warm sound without interference. And secondly, wood is the key not only to high quality but also to the elegant appearance of the device case.
