105 Watts Per Channel — Powerful, Controlled Amplification

With 105 watts per channel across nine amplified channels, the AVC-X3900H drives speakers with authority, precision and composure at any volume level. Dialogue stays clear and anchored, effects retain their full impact, and quiet moments remain nuanced rather than lost. As surround systems grow, Denon's 70% Power Guarantee ensures the AVC-X3900H delivers over 70% of its rated output to up to five channels simultaneously — maintaining balance, dynamics and control as your system expands.

Dolby Atmos, DTS:X, AURO-3D, IMAX Enhanced & 360 Reality Audio

The AVC-X3900H supports the widest possible range of immersive audio formats — ensuring you never miss a dimension of your content, regardless of how it was mastered:

• Dolby Atmos — object-based 3D audio with height speaker support, or upmixed from legacy content using all available speakers
• DTS:X — places sound precisely where it would naturally occur in space, with DTS Neural:X upmixing for legacy content
• AURO-3D — delivers stunning 3D sound for music, games, broadcast and films, with the Auro-Matic upmixing engine for non-native content
• IMAX Enhanced — certified IMAX audio and video processing for a theatre-calibre experience at home
• 360 Reality Audio — Sony's immersive music format places voices, instruments and individual sounds in a 360-degree spherical sound field

11.4 Channel Processing — Build Your System Your Way

Support for 9 amplified channels and 11.4 channel processing gives you the flexibility to design a surround and height speaker layout that suits your room, your preferences and your ambitions. Start with a traditional configuration and expand over time, adding height channels for Dolby Atmos or AURO-3D as your system grows. Four independent subwoofer outputs allow precise bass management for even the most demanding listening environments.

One Hub for All Your Entertainment

Connect your TV, gaming consoles and streaming sources through a single 4K/8K-ready HDMI hub. Six HDMI inputs and two HDMI outputs handle the full breadth of modern sources, with support for 8K pass-through and 4K upscaling to 8K for next-generation displays. Dolby Vision, HDR10+ and HLG ensure the richest possible picture from compatible sources, while eARC and ARC support allows high-quality audio — including lossless Dolby Atmos and DTS HD Master Audio — to travel from your TV to the AVC-X3900H over a single HDMI cable.

High-Performance Gaming

The AVC-X3900H is built for serious gaming. Variable Refresh Rate, Auto Low Latency Mode and AMD FreeSync keep fast-paced gameplay smooth, clean and responsive, while Dolby Atmos and DTS:X deliver 3D spatial audio that moves with the action — sharpening awareness and drawing you deeper into every environment. Combined with 4K/120Hz support, the AVC-X3900H is a world-class gaming hub.

Advanced Room Correction — Audyssey & Dirac Live Ready

The AVC-X3900H includes a full suite of Audyssey room correction tools. Using the supplied measurement microphone, Audyssey MultEQ XT32 measures every speaker in your system and tunes the AV amplifier for the optimal listening experience in your specific room — balancing speaker levels, timing and frequency response for clear dialogue, cohesive surround sound and well-balanced effects.
