Vizio's sound bars offer high-quality audio performance in a compact, easy-to-use design. Vizio has released a few different versions of the sound bar, all similar in terms of installation and use. If you have the HD version of the sound bar, you have one additional audio input that you can use for a high-definition S/PDIF input.
Plug up to two analog audio cables into the "INPUT 1" and "INPUT 2" analog audio jacks located on the right side of the speaker bar's rear panel.
