LG USC9S Soundbar - Black

The '3.1.3 channel' configuration means the soundbar has three main front channels (left, center, right), one dedicated wireless subwoofer for bass, and three distinct up-firing channels that project sound upwards for height effects, creating a truly immersive audio experience.

The triple up-firing channels bounce sound off your ceiling, creating a more expansive and realistic overhead soundstage. This significantly enhances the perception of height and depth in audio, making multi-dimensional formats like Dolby Atmos more impactful.

Yes, you can connect the LG USC9S Soundbar to other TVs via standard HDMI ARC/eARC or optical connections. However, it is specifically made and optimized for LG OLED C Series TVs, so the full benefits of integration and acoustic synergy might be best experienced with those models.

Typically, the wireless subwoofer will automatically pair with the soundbar when both devices are powered on. If not, you'll usually find a 'Pairing' button on both the subwoofer and the main soundbar unit. Refer to your product manual for specific instructions on manual pairing.

The LG USC9S Soundbar has dimensions of 63 mm (height) x 975 mm (width).
