The Denon Flagship AVR-X8500H powers the next generation of home theater with the world’s first 13.2 channel receiver that supports the latest immersive audio formats, including Dolby Atmos, DTS:X and Auro-3D. Built-in HEOS technology supports Amazon Alexa and takes music listening to the next level with wireless whole-home audio and voice control. All eight HDMI inputs (including one on the front) and three HDMI outputs feature HDCP 2.2 compatibility and the latest HDMI specifications, including 4K Ultra HD 60Hz video, 4:4:4 Pure Color sub-sampling, High Dynamic Range (HDR) and 21:9 video, 3D, and BT.2020 pass-through support. It is even ready for Enhanced Audio Return Channel (eARC) for 3D audio playback through TV apps. The feature will be enabled via a future firmware update. Equipped with the full Audyssey Platinum suite of advanced DSP algorithms, the AVR-X8500H features Audyssey MultEQ XT32 automatic room acoustic correction. With the supplied measurement microphone, MultEQ XT32 analyzes each speaker's output (including the subwoofers) at up to eight measurement locations and generates precision digital filters that optimize each channel for the correct frequency and time domain response. Plus, the Audyssey MultEQ Editor app lets you view and adjust settings for detailed tuning and customize the sound more precisely to your room and tastes.
