Setup
1. Placement
Sound Bar: Place the sound bar on a flat, stable surface directly in front of your television, ensuring it does not block the TV's remote sensor. Alternatively, it can be wall-mounted below your TV.
Subwoofer: The wireless subwoofer can be placed anywhere in the room, ideally within 30 feet of the sound bar, for optimal bass distribution. Avoid placing it directly against walls or in corners, which can cause excessive bass resonance.
2. Connecting the Sound Bar
Choose one of the following connection methods based on your television's available ports:
- HDMI ARC (Recommended): Connect an HDMI cable (not included) from the HDMI ARC port on the sound bar to the HDMI ARC port on your TV. This allows audio to be sent from the TV to the sound bar and enables control of the sound bar's power and volume using your TV remote.
- Optical: Connect an optical cable (not included) from the OPTICAL port on the sound bar to the Optical Digital Audio Out port on your TV.
- 3.5mm AUX: Use the included RCA to 3.5mm adapter to connect the sound bar's 3.5mm AUX input to the audio output of your TV or other audio source.

3. Connecting the Wireless Subwoofer
The subwoofer connects wirelessly to the sound bar. Ensure both units are powered on. The subwoofer should automatically pair with the sound bar. If pairing does not occur automatically, refer to the troubleshooting section.
4. Wall Mounting (Optional)
The sound bar includes a wall mount kit for convenient installation. Follow these steps for wall mounting:
- Determine the desired mounting location on the wall, ensuring it is level and centered with your TV.
- Mark the drilling points using the provided wall mount template (if applicable) or by measuring the distance between the sound bar's mounting holes.
- Drill pilot holes at the marked locations.
- Insert wall anchors (if required for your wall type).
- Secure the wall mount brackets to the wall using screws.
- Carefully attach the sound bar to the mounted brackets.
Consult a professional if you are unsure about wall mounting procedures.
