A digital converter box processes television signals into an analogue format for viewing on older TV sets. When the box is connected to an audio-video receiver hooked up with surround sound speakers, the viewer can enjoy multichannel audio with the TV program. The connections require standard composite AV cables and a single video cable to hook up the receiver between the converter box and the television.

Skill level:

Things you need

  1. 1

    Connect the colour-coded plugs on one end of the composite cables to the yellow, red and white jacks on the back of the converter box.

  2. 2

    Insert the plugs on the other end into a free set of AV IN jacks on the back of the surround sound receiver. Make a note of which set of inputs is used for the connection, for example, Video 1 or Video 2.

  3. 3

    Connect the video cable from the Video OUT jack on the receiver to the Video IN jack on the back of the TV.

  4. 4

    Turn on the equipment and set the receiver to the set of jacks connecting it to the digital converter box, for example, Video 1.

  5. 5

    Press the "Input" button on the TV remote until the signal from the converter box appears on the screen.

Tips and warnings

  • Use the remote control that comes with the digital converter box to change channels.
  • No audio connection is required from the receiver to the TV because the surround sound speakers supply the audio from the digital converter box and will likely sound better than the TV's built-in speakers.
  • Disconnect all equipment from electricity while hooking up the AV cables.
