How Does a Home Theater System Work?


Home Theater Components

  • A home theater is a video and audio system specifically made to recreate the stimulation of a movie theater in your home. In order to get a true system, you need certain components. The picture must be detailed and rich. You need a DVD player attached to a television set to watch DVDs in your home theater. The television should be at least 25 inches wide or more. It does not have to be a high-definition TV to work. However, this would greatly enhance the picture quality. You also will need a surround sound receiver, along with at least five speakers and a subwoofer (5.1). Of course, you also have to have all of the connecting cables for the system. A home theater must have all of these components to work to its fullest.

Proper Arrangement of a Home Theater System

  • The home theater must be set up accurately to produce the sound needed. The placement of the individual components is crucial. Each room design produces varying acoustics, people hear tones in a different ways and the systems used differ as well. The channel speaker must be centered above the television. The two front speakers are placed to the left and right of it. The "special" rear speakers emit various background noises to create the surround sound. They give the illusion of being in the middle of the action. The subwoofer sends out booming low frequencies. Several variations should be tested to come up with the best position of the components for the specific room being used.

How it All Comes Together

  • To get the most from your home theater system, you need to watch movies or shows created for surround sound. The video will be displayed on the television screen in front of you in bright, vivid colors. The various audio will come at you from all angles. The sound tracks of the movies are divided into various channels. Each channel is an individual speaker of the home theater system. The tones coming from the right of the screen are transmitted to the right speakers only. The same goes for the center and left audio. Any sounds in the background are heard from the rear speakers. The low rumbles are heard (and sometimes felt) from the subwoofer. It creates the illusion that you are in the center of the action.
