Connecting the Wireless Subwoofer and Rear Speakers
Follow these steps to connect your wireless subwoofer and any optional rear speakers to the sound bar. The system is designed for automatic pairing, but manual pairing is also possible if needed.

- Power Connection: Plug the power cable into the wireless subwoofer and then into an electrical outlet. Repeat this step for any wireless rear speakers.
- Sound Bar Power: Connect the sound bar's power cable to an electrical outlet.

- Blinking Green: Indicates that the connection process is in progress.
- Solid Green: Confirms a successful connection.
- Red: Suggests a bad connection or standby mode.

- Manual Pairing (if needed): If the LED on the subwoofer or speakers shows a red light, a manual connection is required.
- Turn off the sound bar using its power button.
- Press the Pairing button on the back of the subwoofer (or speakers) until its LED blinks green.
- Turn the sound bar back on. A solid green light on the subwoofer/speakers confirms successful pairing.
Optimal Placement
For the best sound quality and to prevent wireless interference, consider the following placement guidelines:
- Place the sound bar close to the wireless subwoofer.
- Avoid placing any obstacles directly between the sound bar and the subwoofer.
- Keep any rear speakers at least 12 inches (30 cm) away from the television.
- Ensure all speakers are at least 40 inches (3.3 ft) away from other devices that emit electromagnetic waves (e.g., Wi-Fi routers, microwaves).
