## Long description

Designed to match LG OLED C series TVs, the SC9S soundbar has a slim, coordinated look and includes a bracket for attaching to compatible LG OLED C series models (55/65/77”, 2022 and later). The bracket supports either wall-mount or table-stand installation and creates a seamless visual alignment between TV and soundbar. The SC9S delivers multi-channel home cinema sound with immersive height effects and is compatible with modern surround formats.
Advantages
The SC9S provides a 3.1.3-channel layout with 400 W total output for powerful, room-filling audio. An innovative center up-firing channel improves voice clarity and enhances surround immersion. Support for Dolby Atmos, DTS:X and IMAX Enhanced adds accurate spatial rendering, while Triple Level Spatial Sound creates an additional virtual layer for a more natural dome of sound. Integrated AI features — Smart Up-Mixer, AI Room Calibration and AI Sound Pro — optimize audio automatically for source type and room acoustics. The soundbar also offers broad connectivity (HDMI, Optical, Wi‑Fi, Bluetooth) and works seamlessly with compatible LG TVs through WOW Orchestra and WOW Interface for combined speaker use and simple on-screen control.

How to use

Connect the soundbar to the TV via HDMI eARC/ARC for full feature support (4K passthrough, VRR, ALLM) or use Optical if HDMI is not available. Power on the soundbar and follow the on-screen setup or the soundbar’s display indicators to complete the initial configuration. For multi-channel immersion enable Dolby Atmos/DTS:X playback from supported content and, if available, run AI Room Calibration to adapt sound to your room. Use the TV remote for convenient control when WOW Interface is supported, or control playback via Bluetooth, AirPlay or streaming services like Spotify.
Recommendations
For best performance, use HDMI eARC connection and place the wireless subwoofer away from walls or corners to reduce boomy bass. Update TV firmware if needed to enable WOW Orchestra or WOW Interface features with compatible LG TV models.
