With the number of components like the LCD flat panel TV and a surround sound home audio system that a home theatre setup needs, it may sometimes be confusing to add another piece of equipment, such as an audio-visual (A/V) receiver, which is actually needed to connect the home theater setup. A good A/V receiver is beneficial in having a good home theater setup as it is actually the piece of equipment that serves as the command center for the entire system and gets all of the audio and video components working together in sync.
The functionality of an A/V receiver depends on every essential piece that is connected together to it appropriately. Once the receiver has been properly set up, any other home theater problems will generally disappear. To guide you on how to properly connect the different home theatre components to your A/V receiver, here are some general information on how the receivers function and what kind of components can be connected to another.
As the A/V receiver is what may be considered the “command center” of your home theater setup, then it means that first it receives data from other home theater devices. Then, it classifies the data it receives, and, finally sends it as output to other devices that are connected to the home theatre system. This allows one to use the home audio system with surround sound simultaneously with a HD-DVD or Blu-Ray player and your LCD flat panel TV, while having to control or monitor only a single home theater component. An audio-video receiver sorts through all of the audio and visual signals that are sent by the different devices, arranging these data so that the appropriate output devices will receive only the signals that they require, while eliminating the number of wires that may be needed to manually connect all of these parts without a central receiver.
Furthermore, an audio-video receiver generally functions as a digital amplifier for your audio system. This means that with this device you are able to watch movies, play games, or listen to music in digital surround sound. To enhance your listening experience, modern A/V receivers have built-in wireless service or USB ports that you can stream music wirelessly from your PC or plug in an external hard drive, which will allow you to enjoy saved music and movies in their digital format without having to burn them to a CD or DVD.
How many home theatre devices can you connect to an A/V receiver?
There are a number of home theater devices that can be joined to an A/V receiver. Besides your television, DVD player, and advanced disc formats such as HD-DVD and Blu-Ray players, you can also attach a stereo CD player, satellite television receivers, a digital video recorder (DVR) or any other similar device, and, like in many cases, some older devices such as an analog record player. Popular gaming systems like the Nintendo Wii, the Sony PS3, and the X-Box 360 can likewise also be easily connected to your receiver so that you may enjoy surround sound to enhance your gaming experience.
One more thing–if your computer is near your home audio system, then you can connect the sound outputs to the receiver for you to take advantage of your existing surround sound system instead of just having to depend on smaller computer speakers.
