How to Hook Up an HDTV With a Cable Box to a Surround Sound System
High-definition TV sets come with different types of audio/video jacks for connecting a variety of components, including a cable box and surround-sound systems. Getting multichannel audio from the cable TV signal means connecting the cable box to the surround-sound receiver, which you then hook up to the TV. High-definition media interface (HDMI) cables will provide the highest quality picture and digital sound available.
Things You'll Need
- HDMI cables or component AV cables, depending on the available jacks.
Using HDMI cables
Check the back of the cable box to see whether there it has a six-sided HDMI jack, which will contain 19 holes set in three rows. Use this connection if available.
Connect the plug on one end of an HDMI cable to the AV OUT jack on the back of the cable box, with the wider end of the plug turned upward.
Attach the plug on the other end of the cable to a free HDMI IN port on the back of the surround-sound receiver. Note which jack provides the cable connection—for example, HDMI 1 or HDMI 2.
Insert a second HDMI cable in the HDMI OUT jack on the surround-sound receiver, and plug the other end into the HDMI IN jack on the back of the high-def TV.
Using Component AV cables
Insert the red, green and blue plugs on a set of component cables into the Video OUT jacks on the back of the cable TV box.
Connect the plugs on the other end to a free set of component Video IN jacks on the surround-sound receiver. Note which set of jacks provides this connection (the jacks will typically have labels).
Plug the audio cables into the Audio OUT jacks on the TV cable box, using the white plug for the left connection. Insert the red plug into the right audio output jack.
Insert the plugs on the other end of the cable into the audio IN jacks on the surround-sound receiver.
Connect a set of component video cables in the same manner to the receiver's Video OUT jacks, matching the red, green and blue plugs with the color-coded jacks. Insert the plugs on the other end into the TV's Video IN jacks. You will not need to connect any audio cables from the receiver to the TV because the surround-sound speakers will handle the task.
Tips & Warnings
- Use HDMI cables if the jacks are available. You can also use both HDMI and component cables, for example, by connecting the surround sound receiver and HDTV with an HDMI cable, but using component AV cables to connect the TV cable box with the surround-sound receiver.
- Do not connect the electric cords until you have hooked up the AV cables.
