11.1.4-Channel True Surround Sound Eleven front and surround channels, one subwoofer channel, and four up-firing channels envelop you in sound. The dual 8" active subwoofer delivers powerful bass optimized with AI-based control technology. With wireless up-firing rear speakers included, sound wraps around and from above by reflecting sound off the ceiling to deliver breathtaking overhead audio. Wireless Dolby Atmos Surround yourself in Dolby Atmos 3D sound, with or without an HDMI cable. Hear every distinct sound from above and around you. Whether it's the sound of helicopters flying in the sky, cars whizzing by, or an orchestra in a concert hall washing over you, feel fully immersed in your content just like in the movies. Q-Symphony Enjoy a more immersive sound experience by pairing a compatible Samsung TV and up to five Samsung audio devices, such as Samsung TV, Soundbars, or Wi-Fi speakers, to work together for a more robust and detailed sound. With compatible AI TVs, it separates voices and background sounds and remasters audio to deliver optimal surround sound. SpaceFit Sound Pro Enjoy stunning sound automatically tuned and calibrated to your room using sensors embedded into the soundbar. The soundbar automatically adjusts sound settings for clear sound and immersion regardless of your room's layout or where the soundbar, subwoofer, and rear speakers are placed. With heightened clarity and immersive audio, enjoy the ideal sound in any space. Adaptive Sound Get the optimal listening experience for each scene. The soundbar intelligently recognizes the type of content you're watching based on real-time scene analysis and automatically adapts audio settings to produce clear voices and detailed sounds. Active Voice Amplifier (AVA) Pro Hear dialogue more clearly. AVA Pro analyzes the background noise in your room and in the content you're watching and automatically enhances voices in the scene, so you'll never miss a word. Sound Elevation Sound can sometimes feel disconnected from the picture, with audio seeming to come from below the screen. To solve this, sound is lifted and positioned closer to the screen, so sound feels like it comes from the same place you're watching. This creates a more natural and comfortable viewing experience across movies, music, podcasts, gaming, and everyday use.
