105W × 9 — 11.4 Channel Processing
Nine power amplifiers deliver 105 watts per channel (8Ω, 20Hz–20kHz, 0.08% THD), with 11.4-channel processing enabling ambitious speaker configurations including height and wide channels. Dialogue stays clear at any volume, effects retain full impact, and dynamics feel natural and uncompressed. Denon's 70% Power Guarantee ensures over 70% of rated output is delivered to up to five channels simultaneously.
Every Immersive Audio Format
The AVR-X3900H decodes every major 3D audio format: Dolby Atmos, DTS:X, AURO-3D, IMAX Enhanced and 360 Reality Audio. Upmixers including DTS Neural:X and Dolby Atmos Height Virtualisation bring legacy content to life even without height speakers. The step up from the X2900H in format support is significant for cinema enthusiasts.
Advanced Room Correction — Audyssey + Dirac Live Ready
Audyssey MultEQ XT with Dynamic EQ and Dynamic Volume automatically calibrates the system to your room using the included microphone. For audiophile-grade precision, an optional Dirac Live Room Correction upgrade is available — bringing measurement-grade acoustic correction to every channel.
4K/8K Video & High-Performance Gaming
Six HDMI inputs (all 8K-capable) and three outputs (1×eARC) make the X3900H a comprehensive 4K/8K hub. 8K pass-through, 4K→8K upscaling, Dolby Vision, HDR10+, HLG and Dynamic HDR are all supported. Gaming performance is maximised via 4K/120Hz, VRR, ALLM and AMD FreeSync — keeping fast-paced action smooth and responsive.
HEOS — Whole-Home Sound
HEOS built-in extends the AVR-X3900H into a flexible multi-room system. Stream from Spotify, TuneIn, Internet Radio, or any networked source to any HEOS-enabled speaker throughout the home. The free HEOS app provides seamless control across all zones.
