Experience game-changing Dolby Atmos sound! Everything you need to build an all-inclusive entertainment system is right here in one simple package. At the helm is a 115 Watt 7-channel receiver that connects all your media players and sends video to the TV via a single HDMI cable– from your old analog game consoles to the latest 4K/60 Hz video with HDR color and 21:9 cinema aspect. Want full smart TV capabilities? Plug a dongle (such as Google’s Chromecast) into the rear side STRM Box port and enjoy a wealth of audio and video streaming apps. Once you’ve connected the speaker system, AccuEQ optimizes the sound to suit the unique shape of your room. Bluetooth lets you enjoy your streamed audio with Onkyo’s legendary clarity and dynamism.
