Denon AVC-X3900H 9.4-Channel 8K AV Amplifier
The Denon AVC-X3900H is a new-generation 9.4-channel AV amplifier designed for immersive home theatre, high-performance entertainment systems and flexible custom AV installations. With nine channels of built-in amplification delivering 105 watts per channel, combined with 11.4-channel processing, the AVC-X3900H provides a strong foundation for sophisticated surround and height-channel configurations.
The Class AB amplification section delivers 105W per channel at 8 ohms from 20Hz to 20kHz with 0.08% THD under 2-channel driven conditions. It also delivers 135W per channel at 6 ohms, 1kHz and 0.7% THD under specified conditions. Speaker compatibility extends from 4 to 16 ohms, allowing integration with a wide range of home theatre loudspeakers.
For immersive sound, the AVC-X3900H supports Dolby Atmos, DTS:X, Auro-3D, IMAX Enhanced and Sony 360 Reality Audio. Its 11.4-channel processing architecture allows additional flexibility when designing immersive surround systems, while four independent subwoofer outputs provide dedicated connectivity for multi-subwoofer installations.
High-resolution music playback is supported through ALAC, FLAC, WAV and AIFF files up to 24-bit/192kHz. HEOS Built-in provides network-based music streaming and multi-room functionality, while Apple AirPlay 2, Wi-Fi and Bluetooth LE Audio provide additional wireless listening options.
Audyssey MultEQ XT32 provides advanced room correction and system calibration, while the AVC-X3900H is ready for the Dirac Live full suite. The platform also supports Dirac Live Bass Control and Dirac ART readiness, providing an upgrade path for advanced acoustic optimization as supported by the applicable Dirac software and licensing.
For video, the AVC-X3900H features six HDMI inputs and three HDMI outputs, with all six HDMI inputs supporting 8K. HDMI connectivity supports 8K/60Hz and 4K/120Hz pass-through, while HDCP 2.3, Dolby Vision, HDR10+, HDR10 and HLG provide compatibility with modern displays, projectors, streaming devices and gaming sources.
Gaming features include Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Quick Media Switching (QMS), Quick Frame Transport (QFT) and AMD FreeSync support, helping provide smoother and more responsive gameplay with compatible equipment.
The AVC-X3900H also provides 11.4-channel pre-outs, 11 speaker terminals, multi-zone audio and video functionality, web-based setup and HDMI diagnostics. Combined with HEOS Built-in and extensive connectivity, it is suited to dedicated home cinemas, premium media rooms, gaming-focused entertainment spaces and custom AV installations.
