Signa S4 is Dolby Atmos Certified* to immerse you in 360 degrees of surround sound.

Plus, standard audio played through the Signa S4 can be up-mixed to create a virtualized Atmos experience. * Requires HDMI eARC connection between sound bar and TV

The Signa S4 sound bar’s advanced seven speaker array was designed to deliver a lifelike Dolby Atmos 3.1.2 listening experience. Its dedicated center channel provides crystal clear dialogue and its optimized left and right tweeters and woofers deliver a huge, wide sound stage. Plus, dual, up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion.
