Setup
1. Physical Placement
- Soundbar: Place the soundbar centrally below your TV. Ensure there are no obstructions in front of the soundbar, especially for the upward-firing speakers, to allow sound to reflect off the ceiling effectively.
- Subwoofer: Position the wired subwoofer on the floor near the soundbar or in a corner of the room for optimal bass response. Ensure the cable connecting the subwoofer to the soundbar is not strained.
2. Connections
Connect the soundbar to your TV or other audio sources using one of the following methods:
- HDMI ARC/eARC (Recommended): Connect one end of the HDMI cable to the HDMI ARC/eARC port on your TV and the other end to the HDMI ARC/eARC port on the soundbar. This allows audio to be sent from the TV to the soundbar and enables control of the soundbar volume with your TV remote (if your TV supports HDMI-CEC/Link).
- Optical: 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 soundbar.
- 3.5mm AUX: Connect one end of the 3.5mm audio cable to the AUX OUT port on your device and the other end to the AUX IN port on the soundbar.
- USB: Insert a USB drive into the USB port on the soundbar to play audio files directly.
- Subwoofer Connection: Connect the wired subwoofer to the soundbar using the dedicated cable. Note that the subwoofer cable is integrated with the power supply for the soundbar.
After making all connections, plug the power cable into the soundbar system and then into a wall outlet.
