home theater system will provide a more comfortable viewing movies and listening to music. It issues surround the presence of sound effects. In modern models of many features that make leisure time more interesting. Therefore the choice of home theater requires a serious and deliberate attitude.
Home Theater - a set of equipment for high-quality multimedia playback. He creates large-scale multi-channel sound, which greatly increases the impressions gained from watching films. For the hearing are available peripheral sounds that can not transmit conventional TV.
All components are arranged so that the viewer is in their environment. It creates a sense of three-dimensionality. Of particular importance are the surround speakers and a subwoofer that reproduces low frequencies. When watching a movie on such a system gives the impression of being in a movie theater, which is why this complex is called.
Design
To understand how to choose a home theater, you need to learn the characteristics of all the components of this system. It includes:
- media playback device (DVD-player);
- Acoustic system (speakers and a subwoofer);
- AV-receiver.
TV - an important part of a home theater, but it has to be bought separately, since it is not included in the set of acoustic equipment. Also, not all systems are equipped with the receiver - the power amplifier can be built, then the home theater will consist of speakers, and video player.
When choosing a system should consider the work of all of the devices individually. The entire complex can be bought in kit or choose your own speakers, amplifier and player. To get a high-quality sound you need to properly collect and connect all components.
DVD-Player
The video player plays back media files from different magnetic media (DVD and CD-ROM drive, flash drives). Before purchasing a product, make sure that it supports all modern file formats required for viewing movies, photos and listening to music.
Most devices have a built-in FM-radio play for Radio channels. Players are equipped with a control panel through which it is convenient to configure and enable the necessary functions at any time.
Check that the DVD-player was equipped with a port for connecting flash drives, since such drives are now more relevant than wheels.
Signal amplifier
Receiver - the equipment for processing the audio signal. It performs the following operations:
- It converts the digital signal that comes from an analog playback source;
- It distributes the signal to the acoustic channels;
- amplifies the audio signal power.
After converting the signal receiver transmits it to the complex acoustic channels - center, rear, front and subwoofer. At the same time it increases the power of distributed sound. This device provides high quality sound throughout the acoustics.
at selecting a receiver pay attention to the power indicator - it should be in the range of 100 watts for a room area squares 20-30. To place more than 30 m² required 150 watts and above.
More product performance affects the frequency parameter. It relates to digital to analog signal conversion. The higher the value, the more the quality will be reproduced sound. In the current model indicates a value of 256 kHz.
The receiver must support the advanced audio formats. These include Dolby Digital Surround, Dolby Digital 5.1, DTS Discrete 6.1 and others. This information can be find out from the consultants in the hardware store.
acoustic system
In a home theater kit sound emitters need to generate sound in a bulk format. Inside speaker sound system is distributed through various channels, which creates a sense of the magnitude of the sound. these speakers can be found in the modern home theaters:
- Acoustics 5.1;
- Complex 7.1;
- soundbar.
Apart from the standard, there are also other configurations of the system - 9.1, 9.2, but they are not very common, because the presence of additional columns gives better sound. For normal flat enough of the most popular kit 5.1. The number five is the number of columns in the system.
In such speakers included:
- Central speaker.
- The two front speakers.
- Two rear speakers.
- Subwoofer.
All speakers on his appointment, and arrange them in need according to the diagram.
Central speaker
It has a horizontal shape and is responsible for dubbing the dialogues taking place in the film. It is set in the center near the TV, usually below. Center speaker must be equipped with a magnetically shielded so as not to interfere with the image.
Front emitters
They play music and a variety of basic sounds. Most often they are made in the form of long outdoor speakers.
In some speaker can not be central speaker or subwoofer. Then the sound signal intended for these devices, is distributed to the front column. The sound quality in this case is getting worse.
Wheel transducers can be two- or three-strip. The latter provides a cleaner sound. They each frequency band reproduces a separate speaker. These elements are mounted on both sides of the TV at a distance of 1-1.5 m. They need to expand a little, pointing to the center of the room.
surround speakers
They create the impression of a circular surround. They are portrayed behind the listener at the corners of the room. Some recommend to deploy them to the wall so that the sound signal is first reflected from the surface.
Now there are home theater speaker as sound panels. They all speakers are placed in one box, which is mounted below the TV. This complex is a primitive replacement 5.1 acoustics and is used in small spaces.
subwoofer
Needed to reproduce low frequencies, i.e. bass. This ultimately improves the sound of all speakers. Usually put the subwoofer near the TVBut it can be put anywhere in the room, because the human ear is bad determines the direction of lower frequencies.
When choosing a good speaker for the house look to its power was enough for a particular room. At the receiver, check that its power does not exceed the sum of the columns, because in this case, the speakers may be damaged.
Also pay attention to the material from which made the speakers. Shells shall be made of wood or chipboard. Plastic or metal housing boxes can cause an unpleasant rattling when playing at high volumes.
