Setup
1. Placement
The SurroundBar 4000 can be placed on a shelf below your television or mounted on a wall. Ensure the soundbar is centered with your TV for optimal audio imaging.
The wireless subwoofer can be placed anywhere in the room, ideally within 20-30 feet of the soundbar, for best performance. Avoid placing it directly against a wall or in a corner, which can cause excessive bass.

2. Connections
Connect the soundbar to your television or other audio sources using one of the following methods:
- Optical Digital Audio (Recommended): Connect one end of the optical cable to the "Optical Out" port on your TV and the other end to the "Optical In" port on the SurroundBar.
- Analog Audio (3.5mm or RCA): If your TV does not have an optical output, use an analog audio cable to connect the TV's audio output to the SurroundBar's analog input.
Connect the power cords to the soundbar and the wireless subwoofer, then plug them into a wall outlet.
3. Wireless Subwoofer Pairing
The subwoofer should automatically pair with the soundbar when both are powered on. If pairing does not occur, or if the connection is lost:
- Ensure both the soundbar and subwoofer are powered on.
- Press and hold the "Connect" button on the back of the subwoofer for a few seconds until the status light blinks.
- Press and hold the "Connect" button on the back of the soundbar (or on the remote, if available) until its status light also blinks.
- The lights should become solid once a connection is established.
