Denon AVC-X3900H 11.4-Channel AV Amplifier
Precision, Power and Control for the Serious Home Theatre
The Denon AVC-X3900H is the next generation of Denon’s acclaimed X-Series AV amplifier range, delivering immersive multichannel home theatre experiences with powerful amplification, comprehensive 3D audio format support, advanced room correction, and flexible system configurations. Precision-tuned in Japan by the Denon Sound Master, the AVC-X3900H brings cinematic sound to life with a richness and authority that makes movies feel more immersive, music more intimate, and gaming more engaging. Whether building a dedicated home theatre or a sophisticated whole-home entertainment system, the AVC-X3900H provides a formidable and future-ready foundation.
Premium Power for Clear, Detailed Sound
The AVC-X3900H delivers 105 watts per channel of clean, controlled amplification across nine independent power amplifier channels, with Denon’s 70% Power Guarantee ensuring more than 70% of rated output is maintained across up to five channels simultaneously. This guarantee is critical in multichannel surround systems where consistent power across all speakers is essential to preserving balance, dialogue clarity, and dynamic impact. Quiet passages remain nuanced and clear, while dynamic scenes deliver genuine impact without strain, across movies, music, and games alike.
Breathtaking 3D Audio Immersion
The AVC-X3900H supports every major 3D audio format available, including Dolby Atmos, DTS:X, AURO-3D, IMAX Enhanced, and 360 Reality Audio, enveloping the listener in 360-degree sound from every direction. With 11.4-channel processing capability and nine onboard power amplifier channels, the AVC-X3900H supports configurations including 7.1.4 and 5.1.6, with expanded layouts achievable through external amplification. Up to four independent subwoofer outputs are supported, with both Standard and Directional subwoofer modes available for smooth, room-filling bass or more precisely localised low-frequency effects tied to onscreen action.
Advanced Room Correction and System Optimisation
Every room shapes sound in its own way, and the AVC-X3900H addresses this comprehensively with a built-in suite of Audyssey room correction tools including MultEQ XT32, Sub EQ HT, Dynamic Volume, Dynamic EQ, and Low Frequency Containment (LFC). These tools align speaker levels, timing, and tonal balance for clear dialogue and cohesive surround performance in any listening environment. For those seeking even greater precision, an optional upgrade to Dirac Live tools including Room Correction, Bass Control, and Active Room Treatment is also available.
One Hub for All Your Entertainment
The AVC-X3900H serves as the central hub for every entertainment source in your home. Six HDMI inputs and two HDMI outputs support 4K and 8K video formats with Dolby Vision, Variable Refresh Rate, Auto Low Latency Mode, and AMD FreeSync for both cinematic and gaming applications. Built-in video upscaling enhances legacy HD content for both 4K and 8K displays, while 4K/120Hz support ensures fast-moving visuals in gaming remain clean and fluid. A Moving Magnet phono input, five analogue inputs, and optical and coaxial digital inputs accommodate every source component with ease.
Whole-Home Sound Powered by HEOS
With HEOS built in, the AVC-X3900H becomes the first zone in a flexible whole-home multi-room audio system, allowing music, TV audio, sports, podcasts, and other content to be streamed to any HEOS-enabled component throughout the home. Wi-Fi and Bluetooth connectivity support flexible streaming from everyday devices, and Bluetooth headphone support enables private listening with onboard output level adjustment for fine-tuning volume. Two-source, two-zone playback with dedicated audio pre-outs and a dedicated Zone 2 HDMI output allows different content to play in separate rooms simultaneously, while a built-in web-based user interface provides full system access from any computer or mobile device on the network.
