Thanks to flexible speaker solutions, DTS:X, and Dolby Atmos support, the STR-DN1080 delivers powerful cinematic surround sound that perfectly adapts to your living situation. Dolby Atmos creates stunningly realistic 360° surround sound that is precisely tailored to your environment, allowing the 7.1.2 speaker channels (including phantom surround back) to envelop you in sound, even from above. The DTS:X decoding provides multidimensional surround sound. Sounds can be accurately positioned around you and above you thanks to nine speaker channels (including phantom surround speakers) and object-based audio decoding. The STR-DN1080 is designed for flexible speaker solutions that adapt to your living space, ensuring you enjoy the best possible audio experience with any configuration. The new flexible speaker solution bypasses potential spatial limitations and "shifts" the sound to simulate the best position and angle for an ideal listening experience. The virtual surround back speaker (phantom) effectively simulates the powerful sound of actual surround back speakers, providing you with full 7-channel surround sound with a 5-channel speaker setup. S-Force PRO Front Surround creates a virtual sound field with surround sound using just two speakers, making it ideal for smaller rooms. Rear speakers behind you are not even necessary for this setup.
