How to choose a home theater photoThe choice of acoustics, DVD - player, TV for home theater.

Quite a simple matter is the choice of home theater. The thing is that here the choice consists not only of a good plasma panel or TV, but also in a complete set of home theater, namely: AV-receiver, DVD-player and speaker system. Of course, almost every store offers you heed the ready-made set of home theaters, but still it is best to choose each component separately. Let's try to figure out how to make the right choice, and then see how to connect the home theater to a computer or TV.

 

First of all, it is necessary to take into account the fact that home cinema takes a lot of space and that is why your first step should be to choose a place in your room. Besides the fact that all components of the cinema must be properly placed, it is also necessary to properly place the audience. Remember that viewing should be fun, but not discomfort.In order to do everything right, you need to consider a few very important rules:

 

  1. The viewer should be at approximately the same distance from the right and left speakers. Best of all, if the speakers will be placed at the same distance from the viewer.
  2. It is very important to take into account the fact that the viewer should not be placed against the wall itself. The thing is that behind the speakers are also located. Rear speakers are usually located above the head of the viewer or at the same height.
  3. Decide in advance on the type of columns. Columns can stand on special racks, and can be placed on a shelf or they can be mounted on special wall brackets. It is very important to know that not all speakers can be placed close to the wall. The thing is that if the column has a rear hole of the phase inverter, then such columns should be placed with a short distance from the wall. If this fact is not taken into account, the speakers may lose low frequencies.
  4. As for the subwoofer, it is desirable to install it on the floor, although it is not so important.

After you have familiarized yourself with the basic rules for the placement of home theater components,now further it is worthwhile to study the rules for choosing these very components.

 

Choose a DVD player for home theater

 

 

DVD player for home theater photoDVD player.Without this device, no home theater can do without, as it reproduces the video itself. Of course, the more formats a DVD player plays, the better, but be sure to ensure that Mpeg-2 support is present. Also, pay attention to the presence of audio codecs, so that your viewing does not turn out to be spoiled when you receive nothing except the image. Mostly now use Dolby Digital and DTS. But if you pay attention to more expensive models of players, then you should know that these players support six-channel sound formats DTS ES and Dolby Digital EX.

 

If you often download videos from the Internet, then you should take care that your DVD player has Xvid and DivX support. This is necessary so that you don’t have to convert the video format downloaded from the Internet, under the required format for viewing on your player.

 

DVD recorders. These players are equipped with a very convenient function - recording video from the TV. Record can be made both on a disk, and on the built-in winchester.

 

Blu-ray format. This is a special format of optical media.It is usually used to record high-density video, as well as to store all digital data in HD format. But in order to be able to reproduce them, this format is necessary. But it is very important to take into account the fact that this format is relatively new and it may be much more difficult for you to find a disc with the desired movie.

 

How to choose acoustics for home theater

 

 

How to choose acoustics for home theaterAcoustics selection- This is the most important point in the selection of all components for home theater. Acoustics and creates the entire effect of the cinema, it completely immerses the viewer into the world of the film and creates a sense of reality while watching. The main parameters when choosing acoustics are:

 

1.Power. This parameter should be taken into account depending on the size of the room where the home theater will be located. So, if the area of ​​the room is no more than twenty square meters, then you just need to buy acoustics with a power of 50 or 70 watts. If the room has an area of ​​up to thirty square meters, then acoustics with a capacity of 100 watts will do. And if the area exceeds thirty square meters, then choose acoustics about 150 watts.When choosing acoustics, be sure to pay attention to how much power is indicated in the instructions. You may encounter two types of power - nominal and peak. Peak power is the maximum power, that is, the one that can be achieved, the device.

2.Frequency range. The higher this indicator is, the better, since this is a special frequency range, thanks to which the audio signal is reproduced. But still it is worth considering that the maximum limit that is possible for the perception of the human ear is 20,000 Hertz. The minimum limit is twenty hertz. But if there is a subwoofer in the speaker system, then it’s not so important what the minimum limit will be.

3.Sensitivity. This parameter is usually measured in decibels. It is important to know that speakers with high sensitivity will make a louder sound (from ninety-four to one hundred two decibels).

 

Now let's smoothlyproceed to the choice of columns. As we mentioned a little earlier - the columns are floor and ceiling. Floor-standing speakers are large and, therefore, are located on the floor.The advantage of these speakers is that they allow for a deeper and more powerful bass sound. But there will be an ideal option for ceiling speakers for those who have a small area of ​​the room, since they occupy very little space. The subwoofer allows you to play the bass. But the most optimal solution - built-in speakers. Installing such speakers is a more laborious task, but as a reward you will get a natural sound.

 

When choosing a speaker, you should consider the complete system, it can be both passive and active. An active system is when each speaker has its own amplifier. A passive system is when there is no own amplifier and where an external amplifier is needed.

 

The highest frequency range will be in the active system. This system is easier to control and there is an opportunity to achieve a better sound than the passive system. The disadvantage of this system is that it is necessary to draw an individual voltage line and a linear signal to each column.
In order to create a voluminous quality sound, it's not enough just to choose high-quality and correct speakers, it's equally important to arrange them correctly.

 

Acoustics of the central channel. In other words, this is just the central column - it reproduces the dialogues (usually in a non-duplicated film), as well as the voice of the translator. This column should be installed as close as possible to the TV. Usually it is placed under the TV or above it. But to ensure that it does not affect the image quality, this column should be magnetically shielded.
Front speakers or two front speakers reproduce musical and sound effects. These columns should have the best all technical indicators. Install them to the right and left of the TV and no closer than half a meter from it.

 

Rear speakers, that is, the two rear speakers produce different sound effects. Install them at the sides or rear.

 

SubwooferNeeded to play bass. Especially good subwoofer reproduces a variety of percussion sounds.

 

How to choose body type

 

 

Case type may be as follows:

 

1. Closed.
2. With phase inverter.
3. With a sound labyrinth.

 

Models with a closed case are the easiest and cheapest. It is necessary to know that the enclosed space does not quite affect the transmission of low-frequency sound. Most modern models of cases are available with bass reflex.

 

Choosing the case material

 

Body material can be made of plastic or wood. The first option is cheaper and has such an indicator as a resonant sound, which in turn negatively affects the sound. It is much better to choose a case from a tree, since in this case the resonant sound is manifested to a much lesser extent.

 

Choosing a TV for home theater

 

 

Choosing a TV for home theaterIn this case, it all depends on how much you have. A CRT television will be easier to use and affordable. Buying a LCD or plasma TV, you get great pleasure from watching your favorite movie, as they are better and giving a real picture. But when choosing a TV for a home theater it's worth taking into account the fact that its diagonal should not be less than 32 inches. For a larger diagonal, you can purchase a projection TV.

 

And a few more tips.

 

When acquiring the components of a home cinema, you should take into account the fact that all this takes up a lot of space and in the near future the cinema will become part of your interior. That is why you should take care in advance about the color of the case.It is advisable to pay attention to the case of wood, as the plastic case gives not high-quality sound. If you want to buy a system with a capacity of 150 watts, in this case, do not forget about the neighbors. For whatever happened unpleasant conversations with them, it is best to take care of the sound insulation of the room where the home theater will be located. And besides the fact that you do not interfere with people in the next room, the quality of the audio track during playback will be much better.
