The Bose Companion 5 is a computer speaker system consisting of two stereo speakers connected to a subwoofer. The self-powered sub plugs into the computer with a USB cable. Bose designed the system primarily for listening to music and audio playback of computer games. If you want to adapt the Companion 5 for use on other equipment, such as a home theatre receiver, you use a converter box with a USB connection rather than a digital optical or coaxial, which is a more common connection method on home electronics. Converter boxes are available at electronics stores.

Skill level:
Moderately Easy


  1. 1

    Turn off the power on the cylindrical control pod for the Bose system.

  2. 2

    Connect the Bose subwoofer's USB cable to the USB port on the audio converter box.

  3. 3

    Plug in either a digital coaxial or optical cable into the appropriate jack on the audio converter box. Connect the other end to a compatible jack on your AV receiver or other component.

  4. 4

    Insert the round plug on the DC power cable supplied with the audio converter box into the electrical socket on the box. Plug in the other end to a 120-volt wall outlet.
