Your sound, your way with the Smart Control

With a fresh, modern design, Smart Control introduces exciting new features such as Soundcheck to help discover the best EQ preset for your taste and Sound Zones that adapt the sound and settings to your location. The app also provides user accounts to make it easier to enjoy sound your way on all your devices.
