Check the type of connection:
The first and foremost thing that you must remember before connecting the home theater systems to your computer is to know about the type of connection that the receiver and your PC support. Usually there are three kinds of connections that allow you to connect the computer with home theaters. First is the analogue connection, which is usually a standard connection in all the PCs. If both your computer and home theater don't have a digital connection, then you will have to use this to connect the two.
Digital connection or the coaxial option generally makes use of a single RCA - RCA cable. As it is a digital connection, no jarring noise would be produced by this connection. But the thing is, all PCs are not equipped to have this kind of connection. Optical connection or digital connection is the third type of connection that makes use of a fiber optic cable to connect the devices. This type of connection is the best one among all the three. These connection features are not available on all PCs. So it is essential to check which type of connection you have.
Connect your PC and Home theater:
If you have purchased a new PC recently, then it will have Dolby digital or DTS bit stream features. This will help you access the surrounding sound while playing DVDs on your PC. If your computer features a multi-channel output to use a powered surround speaker, you can easily enjoy the sound of the home theater systems. You can also connect your PC to a digital optical input on AV receiver end if it possesses an optical digital audio output. This option will help you enjoy the maximum output of home theater through your computer. The output would be so enchanting that you will feel a great difference between them and the computer speakers.
The only drawback of using this set up for your computer is that you should have all the PC, TV and home theater in a single location. For example, you have to keep all close to each other in a room in your home.
