How do I Wire Surround Sound to an HD Cable Box?by Jordan Whitehouse
If you have a high-definition television, an HD cable receiver box will improve the picture for many television stations. It's also possible for you to improve the audio generated by your system if you have surround sound speakers, a receiver and the proper cable. Surround sound systems will typically come with 5.1 digital audio capability, though some come with 6.1 or 7.1. Whatever the capability of your system, introducing surround sound to your home theater will enhance your viewing experience.
Place your speakers in the room, but don't wire them. The front and center speakers should be placed near the television. The front left and right speakers shouldn't be placed any further out than where you'd be sitting. The rear speakers should placed behind the seating area and spaced the same as the front speakers.
Unplug your surround sound receiver, television and HD cable box. Wire the speakers to your receiver. Connect the right speaker to the right input port on the receiver. Also connect the wire attached to the positive port on the speaker to the positive port on the receiver, and the negative port on the speaker to the negative port on the receiver.
Plug one end of your HDMI cable into the HDMI port on your HD cable box. Plug the other end of the HDMI cable into the HDMI port on your receiver. These ports look like USB ports on your computer.
Plug in your cable box, your receiver and your television. Turn each of these devices on.
Set your receiver to "Digital Audio In" mode by pressing the button on your receiver or remote control.
