Premium quality music and sound "presence effect" in the plot of the film, for which a home theater, provide the following audio and video devices:

Columns - how to arrange?

They are arranged around the room, connectingspecial cable. It is this technical solution allows for tremendous reliability and sound effects to transform the illusion of action in "almost real."

AV receiver - what is it?

Usually included in the DVD player - the main unit,combining into a single complex picked up all the equipment. It distributes sounds and they are born and disappear in one, then in another column, thereby creating the magical effect of the "ambient sound", creating in the viewer a sense of what a fine line flickering screen disappeared and he became a participant in the events.

Screen for home theater

Another planning, how to choose a home theater andallocating space for it in the house, usually defined by a screen option. It can be equipped with a diagonal of 29 inches, plasma with a broad color palette for the zone home theater in the living room or a projection TV or a full-size screen projector for home theater a separate room.

Your choice for a home theater projector will be successful if:

  1. The projector is designed for hometheater. Even at a very attractive price do not buy office projector: it is intended only for the transmission of static images and is not able to qualitatively reproduce the "picture" in the dynamics.
  2. A good projector should be large enough and ZOOM lens shift: manual setting of parameters for video on the ceiling, to put it mildly, is not convenient.
  3. The projector should be a few HDMI inputs as either more inputs of various formats can be: more of them, the wider the range of compatible home theater equipment set.
  4. When buying LED projector (LED)Choose the brightness of 500 lumens, optimized to cover the screen with a diagonal of 100 inches. However, the color quality at such parameters ensure that difficult.

You can not pay attention to the passportcontrast settings, lamp power, and also on the technology (LCOS, DLP, 3LCD etc). All projectors intended for home theater systems, capable of providing good video quality. The brightness of the projector does not always depend on the power of the lamps, and for screens with a diagonal of up to 130 inches in general on this option, too, can not pay attention.

Select the receiver is up - been supporting a maximum format

AV-receiver to a home theater systemassigned several functions. The first and perhaps the main is to convert the digital audio signal into an analog and its further transmission to the appropriate channels speaker system: central, rear, and front channel low-frequency subwoofer.

Today, all the equipment to playsound information conforms to the following standards: Dolby Digital and Dolby Sourround Prologgic, MPEG-2 Audio, DTS, as well as the new audio standard THX Sourround EX.

Try to make your chosen receiversupports a maximum playback of popular audio standards: Dolby Digital and Dolby Sourround Prologgic, MPEG-2 Audio, DTS, as well as the new audio standard THX Sourround EX

Therefore, the ideal choice for the home theater receiver should support, if not all, the maximum number of popular formats.

The second function of the receiver - Posted on strengtheningspeakers acoustic signal system. All receivers are equipped with a minimum of five channels of amplification, but when you select the device you need to choose the right power with the following conditions:

  • the greater the power of the receiver, the higher the quality of his work;
  • power front and rear channels should be the same;
  • optimum power receiver for space 30 sq.m. - 100 watts per channel.

Acoustic characteristics and their properties

Despite the obvious importance of all elementshome theater system, his soul is good acoustics. That's the magic of sound quality required to the system's popularity. And the question of how to choose a home theater there is one answer: to create good acoustics.

The perfect sound system - the main condition for creating a good home theater

The perfect sound system - the main condition for creating a good home theater

The vast majority of home theater speaker system used 5.1, in which the audio signal is sent to the following channels:

  • front, left and right;
  • rear, left and right;
  • central;
  • the subwoofer low pass.

Generally, any set of AVformat hardware «in one box" speaker system includes a DVD player with the receiver, "Surround. In this case, selection of speakers for your home theater is to select the sound output speaker and subwoofer low-frequency sound, as well as the material elements of the speaker.

Power - fine-tuning parameters

It is measured in watts. Lack of power amplifier has a negative impact on the dynamics of the sound and its volume, but if the amplifier output is higher power speakers, the speakers may be damaged. Parameters of the acoustic power of the system is selected based on the area of ​​the home theater room:

  • to 12 square meters. m - 15-25 tons per channel;
  • 12-20 m - 25-50 W per channel;
  • 20-30 m - not less than 50 watts per channel;
  • 30 m - 100 watts per channel.

Sensitivity - the ideal "detail" of sound

Measured in decibels. Higher sensitivity acoustics can provide higher sound with equal power. That is, high sensitivity speakers can to some extent compensate for the lack of a power amplifier. Passport indicator acoustics sensitivity of 100 dB / W / m means that one speaker system 1W creates a sound pressure of 100 dB at 1 m. The sensitivity of most mass use of acoustic systems ranges from 85 to 102 dB. The high sensitivity ensures good sound quality, but too powerful amplifier can can damage sensitive speakers.

Frequency Range

Measured in hertz. The indicator provides a reliable audio playback. Speakers can be considered good if it is able to reproduce the entire audio range from 20 to 4000 Hz.

Material loudspeaker enclosure

Plastic and natural wood are the mainthe materials from which manufactures home theater: how to choose the best? Plastic is cheaper, but is characteristic of the resonant sound, affecting the sound quality in general for him. Therefore it is necessary to give preference to wood, if not for all the speakers, then at least for the subwoofer unit.
