Setup
1. Placement
Place the sound bar centrally below your television. Ensure there are no obstructions in front of the sound bar to allow for optimal sound dispersion. The wireless subwoofer can be placed anywhere in the room, ideally within 30 feet (9 meters) of the sound bar, as it connects wirelessly.

2. Connections
Connect the sound bar to your TV using one of the following methods:
- HDMI eARC/ARC (Recommended): Connect one end of the included HDMI cable to the HDMI (eARC/ARC) port on the sound bar and the other end to the HDMI eARC/ARC port on your TV. This connection allows for the highest quality audio, including Dolby Atmos and DTS:X, and enables TV remote control of the sound bar.
- Optical: If your TV does not have an HDMI eARC/ARC port, connect an optical cable (not included) from the OPTICAL port on the sound bar to the optical digital audio output on your TV.
- AUX: For analog audio, connect a 3.5mm audio cable (not included) from the AUX port on the sound bar to the headphone or audio output on your TV or source device.
Plug the sound bar power cord into the sound bar's power input and then into a wall outlet. Similarly, plug the subwoofer power cord into the subwoofer's power input and then into a wall outlet. The subwoofer will automatically pair with the sound bar upon power-up.
