The Sound Bar from Vizio is a compact speaker unit that can be mounted to a wall or placed on a TV stand. It can be purchased with or without a compatible wireless subwoofer. The method you use to connect a wireless subwoofer to the Sound Bar depends on the Sound Bar you purchased. If you purchased a Sound Bar that comes with a Vizio wireless subwoofer, link the devices by pressing the appropriate buttons. If you purchased a Sound Bar that doesn't come with a wireless subwoofer, connect a wireless subwoofer by connecting its transmitter to the Sound Bar.
Connect the audio source to the Sound Bar with an RCA cable.
Connect an S/PDIF or stereo RCA cable to the audio output on the source device, such as a TV or computer.
Connect the other end of the S/PDIF or RCA cable to the S/PDIF input, "Input 1" or "Input 2" on the Sound Bar. If you're using an RCA cable, use either "Input 1" or "Input 2," but not both.
Place the wireless subwoofer less than 60 feet away from the Vizio Sound Bar.
Turn on the Vizio Sound Bar.
Press the "Link" button on the wireless subwoofer.
Press the "Input" button on the Sound Bar. Hold it for 5 seconds. The Sound Bar and subwoofer are successfully linked when the subwoofer's LED stays on continuously.
Connect an S/PDIF or stereo RCA cable to the audio output on the source device, such as a TV.
Connect the subwoofer's transmitter to the subwoofer output on the Sound Bar with a single RCA cable.
Place the wireless subwoofer in the desired location. Do not exceed the maximum distance recommended by the subwoofer's manufacturer.
Follow the instructions provided with the subwoofer to link the subwoofer to the transmitter.
