How to Hook Up Computer Speakers to HD TV

By James Clark

HDTV delivers the best picture available, but the sound can often be improved by connecting an external pair of speakers. Self-powered speakers are required because the amplifier inside the television is not usually powerful enough to drive external speakers. Computer desktop speakers are a good choice. They have a built-in amplifier, usually inside the right-hand speaker. The only extra equipment required for this project is a Y-adapter with RCA audio plugs on one end and a jack with a mini-plug on the other.

Things You'll Need

  • HDTV
  • Y-adapter
  • Computer speakers

Step 1

Insert the white and red plugs on the Y-adapter into the left and right Audio OUT jacks on the back of the HDTV.

Step 2

Connect the plug on the end of the right-channel computer speaker to the mini-plug jack on the Y-adapter. This completes the connection from the HDTV to the computer speakers.

Step 3

Insert the plug attached to the left-channel speaker into the audio jack on the back of the right channel speaker.

Step 4

Connect the AC adapter to the power jack on the back of the right-channel speaker, then plug the other end of the AC adapter into a wall outlet.

Step 5

Switch on the computer speakers, and adjust the volume to the desired level.

Tips & Warnings

  • Switch off the HDTV's built-in speakers by pressing the "Menu" button on the remote control, then using the down arrow button to scroll through the options until "Speakers" is displayed. Use the right and left arrow buttons to switch the built-in speakers on and off.
  • Y-adapters are available at electronics stores.
  • Unplug the equipment from the power while making the audio connections.
