Denon’s immersive 11-channel AVR gives the AVRX6400H the power to make home cinema more ‘cinema’ and less ‘home’ than ever before.
11.2 channels or 9.2.2/7.2.4 Atmos channels for the most immersive surround sound
For the ultimate, reference Dolby Atmos system, this Denon lets you configure four ceiling or Atmos-enabled speakers as well as full 7-channel surround sound. Alternatively, use two Atmos speakers and enjoy a broad soundstage with 'front wide speakers' forming a 9.2.2 system. If you don't fancy a Dolby Atmos specific system but want the most immersive sound possible, go for an 11.2 configuration. This offers 7.2 sound with the addition of front width and front height speakers.
To make the most of the 11-channel processing, the AVRX6400H features a superb quality 11-channel amplifier. Denon’s finest 11-channel amp built into an AV receiver boasts discrete monolithic design. This means that each of the 11 amps have their own circuit board and components. Separation to this level gives ultra-low levels of distortion and reference quality channel precision. The result is home cinema sound that gets closer than ever to the finest cinemas.
HEOS built-in - for the finest multi-room audio
HEOS multi-room music systems connect together by dual-band Wi-Fi, making them easy to set up with your existing home network. Up to 32 HEOS units can be set up at one time, ensuring even the largest of homes are covered for multi-room music. With HEOS already built-in, the AVRX6400H is ready to go as a single 'zone' without any further adaptors!
Control it all with the HEOS app
Once you've set up your HEOS speaker system, you can stream music effortlessly via the dedicated HEOS app. Available for Apple iOS and Android, the app not only lets you stream your stored music but also Internet radio services and popular streaming services such as Spotify, Tidal, Napster and Deezer.
Powerful DSP with AL32 Processing Plus for ultra-low distortion
Featuring no fewer than four, high speed, fourth generation SHARC DSP processors, the AVRX6400H has ample processing power to decode the most complex of soundtracks. Denon's AL32 Processing provides ultra-high resolution digital audio filtering and precision tailoring of the main channels to give pin-point precision and the most natural sound possible.
Auro-3D sound sensation
Auro-3D is the latest surround sound sensation to put you at the heart of the action. Using powerful processing, Auro-3D works with any signal - right down to mono - and recreates a three-dimensional sound stage. For the very best effect, use with height and overhead channels and native Auro-3D material for scintillating surround sound.
Immerse yourself in sound, with Dolby Atmos and DTS:X
Dolby Atmos uses ceiling or upwards firing speakers to produce a multi-dimensional, immersive sound that's a match for the finest cinemas. DTS:X literally pushes the boundaries of what you can expect from home cinema. This highly sophisticated processor renders images in three dimensions that conventional processing can't match. It also offers other advantages such as the ability to boost the spatial effect of conventional DTS and easily adapts with your existing speaker configuration.
Optimised for 4K UHD and HDR
The AVRX6400H supports HDCP 2.2, HDR and BT.2020 via HDMI, which means you can play UHD Blu-ray discs and stream UltraHD video. It's also equipped with UHD 4K upscaling, giving you the most detailed picture on your 4K TV from all sources. The HDMI sockets allow 4K pass-through, for hassle-free switching and viewing without the receiver needing to be turned on.
High-Resolution audio compatible
As well as offering an intense movie experience, the Denon AVR-X6400H is also compatible with High-Resolution Audio. This offers a sound that's far more natural sounding than standard audio. The Denon AVRX6400H supports a wide range of HiRes format files including DSD (2.8/5.6MHz), FLAC, ALEC, AIFF and WAV. It even supports gapless playback for music free from glitches.
Bluetooth, AirPlay, DLNA and built-in wi-fi for the complete networking experience
With both Bluetooth and AirPlay connectivity it's easy to connect up all your smartphones, tablets and compatible lap/desktops and stream music wirelessly. The AVRX6400H also comes with Wi-Fi, Internet radio and DLNA. Simply connect to your home network via Ethernet or Wi-Fi and access thousands of Internet radio sites via vTuner as well as subscription services such as Spotify Connect. DLNA 1.5 compatibility lets you stream from other sources such as your laptop or NAS drive.
Audyssey - making set-up precise and simple
Featuring a comprehensive Audyssey suite of DSP (Digital Sound Processing) functions, the AVRX6400H can be set-up and operated with precision. The package includes Audyssey's MultEQ XT32 technology. The XT32 version of this automatic measuring and set-up device features extra modes and offers the option to measure from eight points for super-accurate room measuring.

Superior satellite speakers
The Monitor Audio MASS satellite speakers are every bit the full-sized speaker, just scaled down. Rather than using inferior components, Monitor Audio uses its hi-fi quality drive units, such as the C-CAM (Ceramic Coated Aluminium Magnesium) tweeter. This has an extended frequency response that stretches right up to 30 kHz, beyond human hearing. Lower notes in the audible range aren't compressed downwards or harmonically compromised, giving a treble response that's smooth, sweet and detailed.
Matching this refined tweeter unit is a similarly impressive woofer. The highly developed C-CAM bass and mid-range integrates smoothly with the treble to give life-like vocals and a natural response. Another technically impressive feature is the woofer fixing. Rather than being bolted to the front baffle, through-bolt construction ensures isolation from the main cabinet and hence a less coloured sound. The result of all this impressive technology is an exceptionally spacious and natural sound quality.
Powerful yet precise subwoofer
Providing power to match the control of the satellite speakers is an equally impressive subwoofer. This sub uses two units b one is actively powered, while the other works in an ABR (Auxiliary Bass Reflex) role. This gives added weight and depth of sound without needing a larger cabinet. It's powered by a 220W Class D amplifier, ensuring tight bass control at all times.
Sleek good looks
With their classy, silver-brushed aluminium caps, gloss back panel and wrap-around speaker grilles, the MASS satellite speakers make a smart addition to any home cinema system. The sub takes a similar shape and is comparatively slim and compact by subwoofer standards. Over all, this is a very unobtrusive 5.1 speaker system.
With class-leading sound and style, it's not hard to see why the Monitor Audio is the What Hi-Fi "Best style package B#600 - B#1000" product of the year.
