How to use

Place the soundbar in front of or beneath the display, maintaining manufacturer-recommended clearances. Position the wireless subwoofer where it produces the desired bass response, typically near a wall or corner for reinforced low frequencies, while keeping it within wireless range of the soundbar. Connect the soundbar to a television or source device using an HDMI (eARC/ARC if available), optical or analog cable for wired audio, or pair via Bluetooth for mobile devices. Enable compatible HDR output and object-based audio decoding (Dolby Atmos / DTS:X) on source devices and the TV if supported. Adjust volume, audio modes and equalizer settings using the included remote or compatible control app as needed.

Recommendations

For optimal immersive sound, enable Dolby Atmos or DTS:X on source content and use HDMI eARC/ARC where available to preserve full audio bandwidth. Place the active wireless subwoofer on a stable surface and experiment with room placement to balance bass level with mid/high clarity. Use wired connections for critical listening or latency-sensitive applications and Bluetooth for casual streaming.
