- HDMI eARC (Recommended): Connect one end of the supplied HDMI cable to the HDMI eARC port on the sound bar and the other end to the HDMI eARC/ARC port on your TV. This connection provides the best audio quality, including Dolby Atmos.
- Optical: If your TV does not have an HDMI eARC/ARC port, connect one end of the supplied optical cable to the TV (OPTICAL) port on the sound bar and the other end to the optical digital audio output on your TV.
- Auxiliary (3.5mm): For older TVs or devices, connect a 3.5mm audio cable (not supplied) from the AUX port on the sound bar to the headphone or audio output port on your device.
