Denon AVR-X6400H 11ch 4K Network AV Receiver With Heos, Wi-Fi & Bluetooth

AVR-X6400H is a powerful 11.2 channel AV Surround Amplifier featuring a high quality monolithic amplifier design as well as the latest 3D object-based audio formats including Dolby Atmos and DTS:X. There are multiple music playback options thanks to Bluetooth, AirPlay and Denon’s HEOS wireless music streaming technology. Despite the extensive feature set daily operation is simple – choose from a regular remote, the Denon AVR remote app or voice control with Amazon Alexa*.

*Requires Amazon Echo device.

Powerful 11 Channel Discrete Amplifier with ECO Mode

The AVR-X6400H features a monolithic power amplifier design with Denon custom made transistors and identical circuit topology on all 11 channels. Each channel is rated at 205 watts and all channels are able to safely drive lower impedance speakers (down to 4 ohms). This ultimate build-quality guarantees best-in-class sound quality with minimum interference, astonishing clarity, power, detail, and depth. Moreover, the 11 channel amplification allows for setting up a full 7.1.4 3D experience without the need of an external amplifier. If not in use for 3D audio the integrated amplifiers can get assigned to drive another pair of speakers in a second audio zone running a different source than the main room. Denon's intelligent ECO mode adjusts power consumption according to signal level, and there's an on-screen Eco Mode display that lets you see in real time how much energy ECO mode is saving.

Advanced Audyssey Room Correction Suite

The AVR-X6400H features the most advanced Audyssey MultEQ XT32 room acoustic measurement system including Audyssey Dynamic Volume, Dynamic EQ, LFC and SubEQ HT. Through these technologies, and with the supplied microphone, it exactly analyses each speaker's output to optimize the overall listening experience. With the additional Audyssey MultEQ Editor App (available for purchase), very advanced users can even go further "under the hood" if desired.

Dolby Atmos Built-In & DTS:X Ready

The AVR-X6400H has Dolby Atmos and DTS:X built-in. These amazing sound codecs allow sound engineers to create surround sound more lifelike than ever before and with Dolby Digital HD and DTS-HD included you can experience the amazing quality of lossless HD audio. AVR-X6400H features the ability to connect a 7.1 surround sound speaker system and 4 additional overhead speakers or Dolby Atmos-certified elevation speakers for the ultimate home theatre experience.

Next Generation Video Formats

The AVR-X6400H supports High Dynamic Range (HDR) video format. It is Dolby Vision compatible and supports HLG (Hybrid Log Gamma). Dolby Vision transforms the viewing experiences with astonishing brightness, contrast, and colour. HLG offers HDR technology over broadcast content. An advanced video processor upscales existing lower resolution video from any analogue or digital source to true 4K. With three HDMI outputs, you can even connect a TV and a projector in the main room, while playing back different content on a second zone screen.

Built-in Bluetooth, Wi-Fi and AirPlay

Featuring Bluetooth & Wi-Fi wireless streaming connectivity, the AVR-X6400H is equipped with an advanced dual diversity antenna transceiver system for robust and error-free streaming, even in congested RF environments. Connect to the internet through your home Wi-Fi network (or with a hard-wired connection via the RJ-45 Ethernet LAN port) and enjoy your favourite tracks from streaming music services such as Spotify Connect as well as from thousands of internet radio stations around the world.

AirPlay lets you play your favourite tracks wirelessly from your iPod touch, iPhone or iPad, and via network streaming you can listen to music files stored on your home PC or Mac, or NAS devices.

Latest HDMI 2.0 Connectivity; HDCP 2.2 Compatible; ISF Certified

All eight HDMI inputs and two HDMI outputs feature HDCP 2.2 compatibility and the latest HDMI specifications, including 4K Ultra HD 60Hz video, 4:4:4 Pure Color sub-sampling, High Dynamic Range (HDR) and 21:9 video, 3D, and BT.2020 pass-through support. It is even ready for Enhanced Audio Return Channel (eARC) for 3D audio broadcast over TV.

Powerful DSP Audio Preocessing

In order to properly handle the multitude of advanced digital audio decoding and processing functions, the AVR-X6400H features a sophisticated DSP audio processing system that incorporates no less than 4 powerful high speed fourth generation SHARC DSP processors. Together these have a combined continuous processing capability of 10 GFLOPS (10 billion floating point numerical computations per second).

HEOS wireless multi-room music streaming built-in

Thanks to Denon’s HEOS technology, the AVR-X6400H can become part of a HEOS wireless multi-room system, allowing you to enjoy your favourite music anywhere – and everywhere – around your home. Share music stored on your home network, Internet radio or streaming services with HEOS wireless speakers, or even other HEOS-capable receivers, throughout the house. And it's all controlled by the free HEOS app, installed on as many smartphones and tablets as you like! The app gives you instant multi-room audio control, meaning you can command music in every room from any device: play different music from different sources in every room, group several rooms together and play the same song, perfectly synchronized, in party mode!

Free Control App

With the free Denon AVR Remote app for iOS, Android and Kindle Fire you can control the receiver's operation, as well as accessing its set-up menu, from a smartphone or tablet. The app also gives you quick access to the receiver's status display, option menus, Denon Blu-ray player control, and an online owner's manual for your convenience. Inside the app, you can switch instantly to the HEOS App to access an incredible level of control over your music contents and streaming services, blast full HEOS wireless multi-room control.

High Resolution Audio

The AVR-X6400H features high resolution audio decoding with multiple lossless file types including ALAC, FLAC and WAV at up to 24-bit/196-kHz along with compatibility for 2.8/5.6-MHz DSD files (DSD is the audio coding format of SACD).

AL32 Processing

AL32 Processing Multi-channel provides ultra-high-resolution digital audio filtering and precision for all audio channels, to deliver a natural soundstage with enhanced imaging. For contents recorded in multi-channel such as Blu-ray discs, the recorded low frequency effects (LFE) may be out of synch and delayed. Bass Sync technology corrects such a delay of low frequency effects for the perfect audio experience.

Best Possible Soundstage

For optimum fidelity and the widest dynamic range with lowest distortion, the AVR-X6400H features advanced reference-class 32-bit AKM AK4458VN D/A converters on all channels. This ensures consistent high fidelity and precise channel matching across all channels for the ultimate listening experience

Smart TV Connectivity

Via the HDMI CEC (consumer electronics control) functionality in your Smart TV, you may be able to control your Denon AVR with the Smart TV's remote control. With “HDMI control” set to ON on your receiver, you can set “Smart Menu” to ON to start controlling your Denon AVR with your Smart TV's remote. The Smart Menu home screen provides you quick access to source and surround mode selections, the AVR’s setup menu, and 4 Quick Selects.

External Control and IP Control Capabilities

The AVR-X6400H is equipped with a range of features to provide enhanced control capabilities and compatibility with 3rd party and custom integration solutions including Crestron Connected.

It can be set up and operated by a home computer on the network via IP control, either via wired LAN connection or Wi-Fi. For direct connection to external home automation and control equipment, it's also equipped with an RS-232C serial port.

For simpler integrated control set-ups, the AVR-X6400H features an IR (infrared) remote control input on the rear panel, allowing remote control compatibility with other components in your home theatre system

Dual Subwoofer Outputs

With a single subwoofer, optimum placement within the room for the best bass response isn't always possible. Depending on the location, bass response at the main listening position can be uneven with audible peaks and dips. With 2 subwoofers positioned in different locations, response averaging evens out the low bass range for more accurate bass anywhere in the listening area

Easy To Setup, Easy To Use

Via Denon’s exclusive Setup Assistant along with the Quick Start guide, you can connect and configure the AVR-X6400H quickly and easily. The Setup Assistant guides you through the process via clear on-screen graphics and text, optimising critical system settings for the best possible sound quality with your particular equipment configuration.
