With flexible speaker solutions, DTS:X and Dolby Atmos support, the STR-DN1080 delivers powerful cinema surround sound that adapts to you and your home. Dolby Atmos produces breathtakingly realistic 360° surround sound that is so precisely tailored to your living environment that the 7.1.2 speaker channels (including Phantom Surround Back) completely surround you with sound, even from above. The DTS-X decoding provides multidimensional surround sound. Nine speaker channels (including Phantom Surround speakers) and object-based audio decoding allow you to position sounds precisely around and above you. The STR-DN1080 is designed for flexible speaker solutions that adapt to your living environment. This way, you always enjoy the best possible audio experience with every configuration. The new flexible speaker solution bypasses possible spatial limitations and "shifts" the sound to simulate the best position and angle for an ideal listening experience. The virtual surround back loudspeaker (= phantom) simulates the powerful sound of actually existing surround back loudspeakers and offers you the full 7-channel surround sound with a 5-channel loudspeaker set. With just two speakers, S-Force PRO Front Surround creates a virtual sound field with surround sound that is also ideal for smaller rooms. You don't even need rear speakers behind you.
