Feel truly immersed in your entertainment with the Samsung 7.1.4 Channel Dolby Atmos Soundbar, boasting 15 built-in speakers to give you the very best in audio. With four upward-firing speakers and wireless rear speakers, you will feel as if you have been gifted by the gods of sound, with audio raining in from every direction. <br /><br />Surround Sound Expansion Plus upscales any standard content you watch or listen to, by adding an overhead layer, creating an amazing 3-dimensional audio bubble. And with 4K Pass Through, you can simply connect a compatible 4K device, and enjoy wondrous sound through your soundbar without image quality being compromised. [ Dolby Atmos ] Dolby Atmos technology creates a 360° audio field above and around you. Conventional home theatres shoot audio directly at you and that creates a two-dimensional sound experience. With Dolby Atmos, sound is multidimensional; it moves around you, fills the space around you, and truly immerses you in the scene. [ Surround Sound Expansion ] Instead of simply generating sound forwards, Surround Sound Expansion fires audio upwards and sideways, bouncing sound off the walls, creating an immersive surround sound experience. [ 4K Pass Through ] 4K Pass Through allows you to connect your 4K device – like a 4K Blu-Ray player – through your Stereo receiver to your TV, without losing picture quality. Many conventional stereo receivers downgrade the quality of the picture when it passes through to the TV which results in lost image quality. [ Samsung Multiroom App ] The Samsung Multiroom app for smartphones and tablets allows you to easily control all of your wireless Samsung sound devices. Provided they’re all connected to your wireless network, you can control what’s playing on the kitchen speaker, and simultaneously turn down the sound coming from your TV Soundbar.
