First, we will discover what makes a home movie different and more desirable performance for a standard TV. When you go the movies, the sound is much better than at home, because the speakers are placed around the theater and not just on the screen and the results of this in what is called surround sound. At home, the speakers are integrated on a television and not the surround effect is obtained and the purpose of a home theater system is to allow the sensation of surround sound in our own homes. This is achieved by using different speakers placed around the room that provides the desired effect. Ideally, a good system will consist of a minimum of two speakers in front of where you sit back and speakers, at least two behind or next to your living room. The sound is divided into channels that are sent to each speaker with each different channel to give movement to sound, an example of how this works is that of a vertical plane passing Start sound that lower the front and only gradually become stronger and when you reach the noise coming from all stakeholders and only from behind. The same applies to the sound coming from one object to one side of the screen if the objective was to the left, then left speakers produce the sound or the right and the right of the speakers would produce sound. The center speaker against acts for balance the sound produced by the left and right speakers to give better quality sound reproduction and therefore, systems with more than two front speakers are much best of two speaker systems.

Splitting the signal into the sound channels for home theater speakers is a device called a receiver, which can also be called receiver audio / video and this unit does all the work involved in the transfer of any input signal on the screen view and audio channels of the surround speakers. The receiver according to where you can buy to support different input devices can be connected simultaneously and selected via the panel control or remote receiver. These devices can include DVD recorders, DVD players, Blu Ray, game consoles, satellite TV, sky and all other contributions that could be used for television. The receiver is then the input of your choice and turn them into two output signals one is a visual signal to access your screen and the other will be an audio signal. The audio signal receiver is divided into channels of surround sound and amplified before leaving the receiver to go to the position of the respective forums. Therefore, a good home theater system would have at least five speakers, including three front speakers and a receiver that can handle as many entries as you require.
