Designed as a perfect match for LG’s C series TVs, the USC9S takes its sound to the next cinematic level, with 3D sound technologies, support for High Resolution Audio, and LG’s Triple AI Sound Optimiser tech. A 3.1.3 channel system houses total audio power of 400W, with an innovative up-firing centre channel providing enhanced voice clarity and surround effects. And a separate wireless subwoofer adds booming bass. Connect to the TV via HDMI or Optical, and with Wi-Fi and Bluetooth too, you can stream your music playlists to its superb sound-stage as well.

Made for LG OLED C series TVs
This soundbar is designed to match perfectly with LG OLED C series TVs with stylish matching design, and a bracket for attaching to the TV. The bracket can be used whether you have the TV wall-mounted or on a table-stand, ensuring a seamless, unified look between TV and soundbar. The bracket is compatible with LG OLED C series TV models from 2022 onwards, 55”, 65” and 77” (a separate bracket is required to wall-mount the TV).

Cutting edge cinematic sound
The USC9S supports cutting-edge surround sound technologies Dolby Atmos and DTS:X / IMAX Enhanced, plus Triple Level Spatial Sound adds an extra virtual layer of sound, creating a dome of audio that makes your home cinema experience more authentic.

High Resolution Audio
High Resolution Audio means studio quality sound, just as the artist intended. Based on a higher sampling rate than standard, high and low frequencies are extended for a greater level of detail across the whole sonic range.

Triple AI Sound Optimiser
The USC9S incorporates intelligent technology to ensure premium sound. A Smart Up-Mixer converts stereo audio into multi-channel surround sound for richer immersion, AI Room Calibration balances audio settings for the room, and AI Sound Pro analyses your content to deliver optimal sound whatever the content.

Smart sonics
You can control the soundbar using external Google Assistant or Alexa smart speakers, and easily stream music from your smartphone via Apple AirPlay or Spotify.

Wireless subwoofer
The separate subwoofer provides bass and sub-bass frequencies that bring your entertainment to thrilling life. And because it connects wirelessly with the main soundbar you have greater flexibility on where to position it for maximum impact.

Perfect match with LG TVs
When paired with a compatible LG TV, you get the most out of the TV’s sound engine. The WOW Orchestra feature offers a greater experience by using the TV speakers with the soundbar at the same time, and you can control the soundbar with the TV remote.

Bluetooth, HDMI, Optical connections & 4K Pass-through
With Bluetooth you can pair up your smart device simply and wirelessly to stream your music to this soundbar's amazing sound-stage. HDMI and Optical ports ensure high quality wired connections, and 4K pass-through means lossless visual data transfer.
