Denon AVR-X overview

  • 1Description

Enjoy immersive multi-channel sound with the Denon AVR-X6400H 11.2-Channel Network A/V Receiver. It delivers up to 140W of power per channel at 8 Ohms and features Dolby Atmos, DTS:X, and Auro-3D compatibility for object-based audio support. Built-in Bluetooth and AirPlay support allow the receiver to wirelessly stream music from compatible sources, such as smartphones and tablets.

Onboard Wi-Fi and Ethernet connectivity allow the AVR-X6400H to access a variety of Internet-based music sources, like Pandora, SiriusXM, Internet radio, and more.

Denon Link HD, AL32 Processing, 11-Channel Monolithic Amplification
The Denon Link HD system, available when the AVR-X6400H is used with a compatible Denon Blu-ray player, is designed to create a high-accuracy digital link with a dedicated connection for master clock data to eliminate distortion caused by jitter errors in the main audio datastream. Meanwhile, AL32 Processing provides high-resolution digital audio filtering and precision in the main (L/R) audio channels to deliver music with augmented high-frequency detail along with a smooth, natural midrange, creating a natural soundstage with enhanced imaging. The power amplification plays its part, too; the 11 power amp channels feature a discrete monolithic design, providing an augmented audio performance.
4th-Generation DSP Processors
In order to handle the multitude of digital audio decoding and processing functions, the AVR-X6400H features a DSP audio processing system that incorporates four 4th-generation SHARC DSP processors, which together have a combined continuous processing capability of 10 GFLOPS (10 billion floating point numerical computations per second).
High-Resolution Audio
Discover the fidelity of high resolution audio tracks with the AVR-X6400H's ability to decode up to 24-bit/192 kHz lossless files (FLAC and WAV; ALAC/Apple Lossless to 24-bit/96 kHz), DSD 2.8 MHz (the audiophile format of SACD), and 5.6 MHz tracks. Play them from memory devices via the front-panel USB or from network sources; the AVR-X6400H will also play lossy file types such as MP3 and WMA.
Built-In Bluetooth, Wi-Fi, and AirPlay Capability
Featuring Bluetooth and Wi-Fi wireless streaming connectivity, the AVR-X6400H is equipped with a dual-antenna system for enhanced streaming even in congested environments. Connected to the Internet through your home Wi-Fi network or with a hard-wired connection via the RJ-45 Ethernet LAN port, it allows you to enjoy your favorite tracks from streaming music services, such as Spotify Connect. You can also choose from thousands of Internet radio stations from around the world and enjoy music and speech entertainment of virtually every genre. Apple AirPlay lets you play your favorite tracks wirelessly from your compatible iPod touch, iPhone, or iPad, and via network streaming you can listen to music files stored on your home Windows or Mac computer or NAS devices.
Denon 2016 AVR Remote App
With the free Denon 2016 AVR Remote app for iOS, Android, and Kindle Fire, you can control the receiver's operation and access its setup menu from a smartphone or tablet. The app also gives you 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 additional control over your music contents and streaming services, plus full HEOS wireless multi-room control.
11-Channel Discrete Amplifier with ECO Mode
The AVR-X6400H features a monolithic power amplifier design with identical circuit topology on all 11 channels. Each channel is rated at 140 watts (8 Ohms, 20 Hz to 20 kHz, 0.05% THD) and all channels are able to safely drive lower impedance speakers (down to 4 Ohms). Additionally, the 11-channel amplification allows for setting up a 7.1.4-channel 3D experience without the need for an external amplifier. If not in use for 3D audio, the integrated amplifiers can be assigned to drive another pair of speakers in a second audio zone running a different source than the main room. Denon's 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.
Dual Subwoofer Outputs
A single subwoofer can give an uneven bass response at the main listening position, with audible peaks and dips. The AVR-X6400H provides connectivity for two subwoofers; positioned in different locations, they will even-out the low frequencies for more accurate bass anywhere in the listening area. It also provides Audyssey Sub EQ HT to give individual tailoring of each subwoofer via digital signal processing.
Smart TV Connectivity
Using the HDMI CEC (consumer electronics control) functionality provided on some smart TVs, it's possible to control Denon receivers with the TV's remote. Set the receiver's "HDMI control" to ON, choose the "Smart Menu" receiver control function on the TV, and the Smart Menu home screen allows direct access to a range of receiver functions, including source and surround mode, the main setup menu, and the Smart Select "one-touch" presets.
Audyssey Room Correction Suite
Equipped with the Audyssey Platinum suite of DSP algorithms, the AVR-X6400H features Audyssey MultEQ XT32 automatic room acoustic correction. With the supplied microphone, MultEQ XT32 analyzes each speaker's output (including the subwoofers) at up to eight measurement locations and generates digital filters that optimize each channel for the correct frequency and time domain response. Audyssey Dynamic Volume smooths out annoying jumps in volume, such as TV commercials, letting you listen at lower levels and still enjoy clear dialogue, music, and sound effects. Audyssey Dynamic EQ provides tonal tailoring for full-range clarity at nearly any listening level. Audyssey Low Frequency Containment uses psychoacoustic algorithms to deliver a full-range tonal balance, including deep bass, but without disturbing close-by neighbors or family members in other rooms. It also features a multi-step adjustment that lets you dial-in the amount of containment to your preference. Audyssey Sub EQ HT provides individual DSP tailoring of each subwoofer in a dual-subwoofer setup for deeper bass with improved definition compared to a single-subwoofer configuration.
Audyssey MultEQ Editor App
This app allows you to view and customize the sound more precisely to the specifics of your room, and tailor it to your personal preferences. The app provides functionality to view the speaker detection results, view the before and after results of the Audyssey calibration, edit the resulting Audyssey curve for each channel pair, adjust the overall EQ frequency rolloff for each channel pair, and adjust the target sound curve high-frequency rolloff. The Audyssey MultEQ app is available for purchase from the Apple App Store, Google Play, or the Amazon app store.
Wired Multi-Source/Multi-Zone Support
You can enjoy your favorite movie in the main room while others enjoy stereo sound from different sources in two other rooms, because the AVR-X6400H is equipped with pre-amp outputs for a 2nd zone and 3rd zone. There's also a dedicated HDMI output for 2nd-zone audio and video so you can watch and enjoy two different video sources at the same time.
Designed for Easy Setup and Use
The AVR-X6400H's graphic on-screen display is designed to be easy to understand as it guides you through the set-up process to ensure the correct configuration.

    Rated 5 out of 5 by from Lots of flexibility and great options I have a Klipsch 7.1 speaker setup and wanted to expand it to a 7.1.4 system.� The Denon avr-x6400h made the transition easy. I added 4 Klisch Dolby enabled RP-140SA speakers as front and rear height speakers instead of reflecting their sounds off the ceiling.� The result was a fully compatible 3D sound speaker setup (Dolby Atmos, DTS:X, and Auro-3D).� Denon's documentation (pdf) is exceptional and very detailed.� As a result I clearly know my many options and how to select just what I want.� I have found that the Auro-3D up conversion does a wonderful job of converting stereo PCM to an immersive 3D sound field.� Naturally Dolby Atmos and DTS:X 3D effects are shockingly good.� Moreover, the information processing screen displayed on the TV screen is as impressively complete as I can get from my OPPO 203.� Amazing!� Now my sound system is an excellent match for my OLED display!
