How to Connect an HDTV to Your Sound System or Home Theater
Systems are different, but here are the general steps to connect your HDTV to your home theater or sound system.
First, check your HDTV unit's input/output ports. Usually at the side or in back. Input jacks receive signals, output jacks send signals from your HDTV to your system.
Now, check your audio amplifiers input/output ports, they're usually in back. Here are the ports on a typical home theater unit.
There are three main ways to make audio connections. Most all audio components offer RCA style connecters. While these will do the job, you only want to use them if you don't have the digital connection option. Since digital provides better quality audio.
Digital coax or tussling cables carry the audio signal digitally. If you have a digital optical audio out on your HDTV and a digital optical audio in on your sound system, use these. Newer equipment, like some DVD players and HDTV tuners, are designed for home theaters. So they probably have a digital audio output.
A third option is an HDMI cable, for combined digital, audio and video connections. This may be your best option if your home theater supports it, because a single cable carries both video and surround sound audio.
One quick tip, if you're connecting older components to newer ones, you may have to buy adapters from an electronics store.
