Setup
1. Placement
The soundbar can be placed on a flat surface, such as a TV stand, or mounted on a wall. Ensure the soundbar is centered below your television for the best audio experience. The wireless subwoofer should be placed on the floor, ideally in the front corner of the room or near the soundbar, to optimize bass response.

- HDMI (eARC/ARC) Connection: For the best audio quality and control, connect an HDMI cable (not included) from the HDMI (eARC/ARC) port on the soundbar to the HDMI ARC/eARC port on your TV. This allows audio to be sent from the TV to the soundbar and enables control of the soundbar volume with your TV remote (CEC).
- Optical Connection: If your TV does not have an HDMI ARC/eARC port, connect an optical cable (not included) from the OPTICAL port on the soundbar to the Optical Digital Output port on your TV.
- AUX Connection: For analog audio sources, connect a 3.5mm audio cable (not included) from the AUX port on the soundbar to the audio output of your device.
- USB Connection: Insert a USB drive into the USB port for playing compatible audio files (MP3/WAV/FLAC/AAC).
3. Wireless Subwoofer Pairing
The subwoofer is designed to pair automatically with the soundbar. If the subwoofer does not connect automatically, follow these steps:
- Ensure both the soundbar and subwoofer are powered on.
- On the rear of the subwoofer, locate the "PAIR" button.
- Press and hold the "PAIR" button for a few seconds. The indicator light on the subwoofer will flash rapidly.
- The soundbar will automatically detect and pair with the subwoofer. Once paired, the indicator light on the subwoofer will turn solid.
