Denon AVRs (like the AVR‑X3800H, X4800H, and X8500HA) offer native Auro‑3D decoding, adding immersive height and overhead “Voice of God” channels to your home theater setup. When playing non‑Auro‑3D content, Denon’s Auro‑Matic up‑mixer intelligently spreads stereo, 5.1, or 7.1 mixes into a realistic 3D soundfield. The receivers auto‑switch between Auro‑3D native playback and Auro‑Matic up‑mixing depending on the source, ensuring seamless transitions. Users praise the up‑mixer for creating spacious sound in Atmos hybrid systems, though performance can vary room to room. Note: Denon discontinued its Auro‑3D firmware upgrade program as of May 2024 — new models include Auro‑3D out of the box, but older ones can’t be upgraded after that date.
