Denon AVC-X3900H: Dolby Atmos 9.1.4, DTS:X 11.1££££
Of course, it is always possible to apply all available audio processing to a Dolby signal. Thus, it is now possible to activate DTS Virtual:X on a Dolby Digital 5.1 soundtrack. And to return to the HDMI 2.1 inputs/outputs, these support all the standard's features: VRR, ALLM, eARC, QMS, QFT, Ultra HD, 4K 120 fps up to Ultra HD 8K 60 Hz (see our news article "HDMI 2.1 Standard: Welcome Official Additions, Technical and Ergonomic"). Note that only two of the three HDMI 2.1 outputs support 8K.
Denon AVC-X3900H: Streaming, Hi-Res Audio and Audyssey calibration
For the rest, we find a discreet 9.4 configuration, Dolby Atmos 9.1.4, Dolby Height Virtualization and DTS:X 11.1 processing (with the addition of an external stereo amplifier), Auro 3D decoding, the Bluetooth TX function to stream the audio signal to compatible headphones in addition to the speakers. It is therefore possible to enjoy your music on the living room speakers but also in the kitchen or bedroom via wireless headphones. Note that Bluetooth LE is supported. Also present is the ability to enjoy multichannel decoding in the main zone (the living room, for example) and simultaneously stream the downmixed stereo signal to the Heos 2 zones; the ability to combine a video signal (such as a digital terrestrial television broadcast) with an audio signal from another source (such as an audio CD) in the main zone. Finally, thanks to the integrated Heos multiroom module, the Denon AVC-X3900H offers the ability, within a Heos setup, to distribute a source to another component of the Heos chain.
Denon AVC-X3900H: network functions, Hi-Res Audio and Audyssey calibration
Also on the menu of the Denon AVC-X3900H, Spotify Connect certification, AirPlay 2, Dual Band Wi-Fi and TuneIn internet radio, UPnP (DLNA) audio gateway, compatibility with Amazon Music, Deezer, SoundCloud, Tidal… Plus DSD 2.8/5.6 MHz, FLAC, WAV and ALAC up to 192 kHz/24 bits in addition to MP3, [abc]WMA[/abc] and [abc]AAC[/abc], and support for 4 or 8 ohm output impedance. Not forgetting compatibility with the paid Audyssey MultiEQ Editor app and two parallel subwoofer outputs.
Specifically, Audyssey calibration allows you to store two separate configurations in memory, for example 2.0 and 9.1.2, or the result of the Audyssey calibration and a custom MultiEQ curve, with the ability to select either one on the fly for comparison.
Denon AVC-X3900H: HDMI 2.1 connectivity and Pre-Out 11.4££££
On the HDR side, it naturally supports HDR10, HDR10+, HDR HLG, and HDR Dolby Vision, not to mention BT.2020 color gamut support. 4K Pass-Through is also included. Note that the Denon AVC-X3900H is Roon Ready certified.
Denon AVC-X3900H: 1080p Color OSD and Optimized Ergonomics
The OSD is still 1080p color (not 480p). A wealth of information is now displayed on the screen, including the nature of the input and output signals, such as which channels are actually active. Similarly, the four Quick Select buttons on the front panel still allow quick and easy access to the desired source. These buttons also integrate additional functions and modes (Audyssey and multiroom management) for even more comprehensive macros. The optimized design further reduces the signal path and the risk of interference.
