Features home theater class Hi-Fi

The desire to improve the set of their home equipment is inherent in every owner. Someone stops at the original version of the configuration, well, many gradually improve everything system components. There comes a period when it becomes relevant to purchase equipment for a high-quality cinema - hi-fi class. Mistakes are unacceptable: they are costly both financially and emotionally.

World of high sound

The main objective of this cinema - the embodiment of the maximum possible sense of presence. The owner of such a home system should feel like a real participant in the events, a listener of a symphony orchestra performing in an imaginary hall of the conservatory.

It should be noted that the value of real penetration and the range of emotional perception depends entirely on the quality of the cinema.

Scientific research has shown that the decisive impact on the human psyche is exerted by the sound component, and not by the video sequence. Therefore, the creators of home systems pay great attention to all, without exception, the components of the cinema, including the connecting wires. The overall class of the home installation is determined by component class.

Among the cinemas for the home dominate the standard low budget items. They are fairly inexpensive, and at the same time fit well into the home interior, having fairly tolerable acoustic parameters, good power, which is enough for playing movies and music. The standard consumer has a wide choice in this segment of cinemas.

For more demanding and secured fans of high-quality audio and video, class movie theaters are provided. Hi-Fi (Hi - Fi). Despite the fact that they are much more expensive than ordinary home installations, the choice in this segment is quite large.

What is really HI-Fi?

There is no clear answer to this question. Reducing Hi-Fi (“high fidelity”) is more likely a sign high sound level. As a rule, this stamp was inherent in the equipment of the second half of the last century. The main indicator for that period of time was the reproducible frequency band - from 20 Hz to 20 KHz, plus a non-linear distortion factor of 3%. At the moment, these figures are not a guarantee of high-quality sound.

The technology of modern manufacturers of home appliances has grown significantly, so the Hi-Fi format is currently not so much a technical standard as a trade brand.

Modern processors and microcircuits have the ability to easily place sound in the range from 20 Hertz to 20 kilohertz, but the components of acoustics systems, sold under the name Hi-Fi, often do not correspond to the parameters of high sound quality. This kind of cinema, and most of them are on sale, even they cannot cope with multimedia problems. Most firms that produce true hi-fi define high quality sound with the term “high precision».

Systematics HI-FI

Before purchasing a bundle of this Hi-Fi, it’s helpful to prioritize your future home system. According to the complexity of tasks, the Hi-Fi equipment is divided into only two subsections:

• playing a number of music;
• viewing film production.

It would seem, why it is impossible to listen to a good concert at a prestigious cinema? Of course, it is possible, but if we consider the reproduction of various types of products, then one cannot do without a distinction.

Today produce the latest models amplifierswhich cost more than a few home complexes taken together. This price is dictated by the ability to feel the "live sound" in its full dimension, to convey all the subtle nuances of performance, the ability to hear the sound of the butterfly wings clap. The most expensive receivers for cinemas will not help in the transfer of such subtle differences, and not because of poor production, they just have other goals.

Hi-Fi selection features

Recently, cinemas made according to the principle of "all together." For a relatively small amount of proposed player, built-in amplifier for multiple outputs, plus acoustic kit. To classify such combinations as Hi-Fi is possible only by the band of transmitted acoustic frequencies. For the desire to hear the true sound of an acoustic concert, you must pay an order of magnitude more expensive.

It is advisable to know "in the face" of the company, which are engaged in the production of only high-quality technology and nothing else. It is such manufacturers that, due to their narrow specialization, can be fully trusted.

For example, you can specify the company Onkyo, producing high-end components.

Many manufacturers began to devote much time to creating "designer" complexes to raise the market rating. Basically it touched acoustics systems. It is necessary to take into account that the trendy, beautiful, narrow and flat speakers with tiny speakers can only improve the modern interior of the apartment, but the sound of good quality cannot be obtained from such a device. Acoustics, of course, need to enter into the interior, but not forgetting the laws of "advanced sound."

So, if the idea to purchase home equipment of Hi-Fi class acquires the features of reality, listen to a number of practical recommendations, perhaps they will provide substantial assistance in a difficult choice.

Key value receiver

A quality receiver is the general headquarters for managing a cinema. All devices of the system are connected to it. Such receivers are required to have a variety of digital inputs, there are also analog ones, you can even connect game console. What you need to focus on:

1. Working power. An input signal is supplied to this device without amplification. For transmission to the acoustics, the signal must be amplified. Please note that as a rule, the amount of power is indicated per channel. Roughly speaking, power is fully realized when only one column is turned on. At connect all devices, power will fall in proportion to their number.
2. Digital Converter Quality is fundamental to high-quality sound, which is obtained from digital inputs.
3. Current parameter. He talks about the possibility of maintaining a low-frequency signal at a stable level for a long time. If the value of this parameter is not high enough, then there is a probability that the low-frequency sound will attenuate and then merge into a common buzzing sound.
4. Audit Listen. The receiver provides only about a third of the final sound and it is better to listen to its sound with the selected acoustics. After all, each person’s individual perception of sound is different, plus listening is best done not in “greenhouse conditions”, but in the workroom.

Speaker Selection

If you look, the speaker system is your pure sound. The market is full of acoustics of various sizes and shapes. What should you focus on when choosing?

1. Power magnitude. Just do not confuse with the volume parameter. Power speaks more about reliability, answering the question what signal a given speaker can miss. To maintain high quality, it is necessary that the nominal power of the acoustics be higher than the limiting power of the amplifier. The impedance matching with the amplifier unit is also important.
2. Beep Spread Measure. The more this indicator has a speaker system, the more convenient it is to place it, since turning to the listener does not become mandatory. There are a number of columns with a small indicator, which are designed for a single listener.
3. Bass reflex location. To the wall of the room, you can install the acoustics with the frontal phase inverter.This greatly simplifies the design task. In the variant of the rear location there is a danger of the appearance of a “porridge”. The noise absorbing material located behind the speakers can help.
4. The number of transmitted frequency bands. The speaker in the singular is not able to reproduce the entire range of frequencies. Designers use different types of speakers to play different frequencies. Ultimately, the 3-way speaker has separate speakers for listening to its range.

Before purchasing, any system needs to be heard live, because each decorates the sound in its own way.

Making the final decision on acquiring a Hi-Fi class cinema is necessary on a weighted basis and with the help of a rigorous assessment of all factors, not losing the meaning of many details, especially those that at first glance may seem insignificant. It must be remembered that the qualitative effect can be obtained only if all the equipment is properly placed, taking into account the interior features of the room.
