Television technology has changed rapidly over the last few years. You can now purchase large flat-panel televisions that will display stunning high-definition video for economical prices. But while the picture and price is great, many audio enthusiasts find the audio performance of many of these televisions to be somewhat disappointing. A quick and relatively inexpensive way to improve the audio performance of your television is to add powered speakers or a multi-speaker soundbar to your television.

Skill level:
Moderately Easy

Things you need

  • Television

  1. 1

    Locate the "line-out" audio jacks on the rear of your television. This will be a pair of RCA jacks, colour-coded red and white. They will usually be labelled as "audio out," or "audio line out." This is a preamp-level output, used to send the audio signal to a separate amplifier or powered speakers set up.

  2. 2

    Position your powered speakers or soundbar by your television. If you're using two powered speakers, put one on each side of the television. A soundbar should be placed in front and below the television. Consult the manual for your speakers for information on placement and mounting options. Plug the speakers into an electrical socket or power strip.

  3. 3

    Connect the input cable for your powered speakers or soundbar to the line-out audio jacks of your television. Place the red plug in the red jack, and the white plug in the white jack. Some powered speakers may have a cable that terminates in a 3.5mm stereo minijack plug. If this is the case, plug the cable into an adaptor cable with a female 3.5mm stereo minijack cable on one end, and a pair of RCA plugs on the other. These are available at most electronics retailers.

  4. 4

    Set your television's audio output. In the television's menu, you'll have several options for audio output. If you wish to control the speaker's volume through the television, set the line output to "variable." If you wish to control the speaker's volume through the powered speakers' volume control, set the television's audio ouput to "fixed." You can also turn the television's internal speakers on or off, depending upon your preference. Consult your television's manual if you need help finding the correct menu settings.
