The Denon AVC-X3900H is a 9.4 channel AV amplifier with 11.4 channel processing, delivering 105 watts per channel (8 ohm, 20Hz-20kHz, 2ch driven) with support for Dolby Atmos, DTS:X, AURO-3D, IMAX Enhanced, and 360 Reality Audio. It sits in Denon's X-Series as the step-up from the AVR-X2900H, adding more channels, more power, and a significantly wider surround format support.
Nine internal amplifier channels and 11.4 channel pre-amplifier outputs allow configurations from 5.1.4 and 7.1.2 Dolby Atmos to full 7.1.4 with an external two-channel amplifier on the height channels. Four independent subwoofer outputs provide precise bass management across multiple subwoofers. ProHiFi is an authorised Denon dealer in India.
Audyssey MultEQ XT room calibration is included as standard, with an optional upgrade path to the full Dirac Live room correction suite for more advanced room tuning. The 70% Power Guarantee ensures over 70% of rated output across five channels simultaneously, maintaining clean and balanced surround performance under real-world conditions.
Six HDMI inputs (all 8K capable) and three HDMI outputs (including eARC) support 4K/120Hz, 8K/60Hz, HDR10+, Dolby Vision, VRR, ALLM, and AMD FreeSync. HEOS built-in covers wireless multi-room streaming, with AirPlay 2, Bluetooth, Spotify Connect, and hi-res audio playback up to 24-bit/192kHz and DSD 2.8/5.6MHz. Josh.ai voice control is also supported for smart home integration.

Why Consider the Denon AVC-X3900H
The AVC-X3900H is the right choice for home cinema enthusiasts who want the full range of immersive audio formats, including Dolby Atmos, DTS:X, AURO-3D, and IMAX Enhanced, in a single amplifier with genuine expansion capability. The 11.4 channel pre-out means the system can grow to a full 7.1.4 Atmos layout with an external stereo amplifier, and four independent subwoofer outputs provide the kind of bass management normally found only on much more expensive processors. The optional Dirac Live upgrade gives access to one of the most respected room correction platforms available. Compared to the AVR-X2900H, the AVC-X3900H adds two amplified channels, 11.4 pre-outs, four subwoofer outputs, AURO-3D, IMAX Enhanced, and all-8K HDMI inputs, making it the natural next step for buyers building a more ambitious system.
Ideal for
- Home cinema rooms wanting 5.1.4, 7.1.2, or 7.1.4 Dolby Atmos configurations
- AURO-3D and IMAX Enhanced enthusiasts needing native format support
- Systems with multiple subwoofers requiring 4 independent sub outputs
- Listeners who want the option to upgrade to Dirac Live room correction
- Next-gen console gamers needing 4K/120Hz, VRR, and AMD FreeSync
- Multi-room audio setups using HEOS, AirPlay 2, or Bluetooth
