  3. The projector should be some HDMI inputs or as many inputs of different formats: the more of them, the wider the range of compatible home theater set of equipment.
  4. When buying LED projector (LED) Selects the brightness of 500 lumens, for optimum coverage of the screen with a diagonal of 100 inches.However, the color quality at such parameters ensure that difficult.

can not ignore the passport Contrast, wattage, as well as 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 screens with a diagonal of up to 130 inches in general on this option, too, you can not pay attention.

Select the receiver is up - been supporting a maximum size ↑

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

Today, the entire apparatus for reproducing the audio information corresponding 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 receiver supports the most popular standards for audio signal : Dolby Digital and Dolby Sourround Prologgic, MPEG- 2 Audio, DTS, as well as the new audio standard THX Sourround EX

therefore the ideal choice receiver for home theatershould maintain, if not all, the maximum number of popular formats.

The second function of the receiver - is fed to the column reinforcement speaker signal.All receivers are equipped with a minimum of five channels of amplification, but the choice must be to choose the right power devices 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 properties ↑

Despite the obvious importance of all elements of the home theater system, it is the soul of 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 system

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

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

As a rule, any set of audio and video equipment format «in one box" speaker system includes a DVD player with the receiver "surround sound.In this case, the choice of speakers for home theater is to select the output sound speakers and subwoofer low-frequency sound, as well as the material elements of the speaker system.

Power - fine-tuning parameters

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

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

sensitivity - ideal "detail"

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

Frequency

measured in hertz.The index provides a faithful reproduction of audio.Speakers can be considered good if it is able to reproduce the entire audio range from 20 to 4000 Hz.

Housing material speaker

plastic and natural wood are the main materials of which are made of home theater: how to choose the best?Plastic is cheaper, but it is characteristic resonant sound, degrade the quality of sound in general.Therefore it is necessary to give preference to a tree, if not for all the speakers, then at least for the subwoofer unit.
