By fully immersing the listener in a cocoon of life-like sound, Auro-3D puts you right in the middle of the action. Auro-3D provides an immersive surround sound experience thanks to dedicated height and overhead channels, in addition to the regular channels. The height information, captured in recording or created during the mixing process, is mixed into a standard 5.1 PCM stream that comes with a regular Blu-ray. Moreover, the Auro-3D Engine combines different technologies to guarantee an optimum 3D sound experience generated both natively and from existing audio content. It recognizes mono, stereo, 5.1 surround or an Auro-encoded signal and transforms them into 3D audio. Once upgraded with the Auro-Codec decoder, the Denon AVR-X6300H is capable of decoding the original Auro-3D mix and playing back an Auro-3D 9.1 or 10.1 channel configuration. Auro-3D Upgrade can be purchased for $199.

Prepared for the future, with no fewer than eight HDMI inputs (including one conveniently located on the front panel) and three HDMI outputs, the AVR-X6300H’s advanced video section features 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 on every input. It also features HDCP 2.2 compatibility, a requirement for 4K Ultra HD copy-protected content, ensuring ready for the next generation of Blu-ray disc players, set-top boxes and other 4K Ultra HD sources. In addition, the video processor can also upscale analogue and digital SD and HD video to 4K Ultra HD. 

Certified by the Imaging Science Foundation, the AVR-X6300H features a full suite of video calibration controls (for use by an ISF technician), along with ISF Day and ISF Night video modes.

Featuring Bluetooth and Wi-Fi wireless streaming connectivity, the AVR-X6300H is equipped with an advanced dual antenna system for robust and error-free streaming even in congested urban 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. AirPlay 2 lets you play your favorite 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.

The AVR-X6300H features a monolithic power amplifier design with Denon custom made transistors and identical circuit topology on all 11 channels. Each channel is rated at 140 watts (8 ohms, 20Hz~20kHz, 0.05%THD) 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’s, 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. 

A single subwoofer can give an uneven bass response at the main listening position, with audible peaks and dips. The AVR-X6300H provides 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.

With the free “Denon 2016 AVR Remote” for iOS, Android and Kindle Fire, available from the Apple app store, Google Play or the Amazon app store, 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.

The latest Denon audio video products use Audyssey MultEQ for simple, accurate set-up and calibration of your system to the room in which it’s used. But now you can go further with the Audyssey MultEQ Editor app, going “under the hood” to view and adjust settings for detailed tuning – allowing you to customize the sound more precisely to the specific problems in your room, and tailor the sound to your personal preferences. With this comprehensive app, you can harness the power of Audyssey MultEQ to take total control of the way your home cinema sounds.

• View the speaker detection results, to check correct installation.
• View before and after results of the Audyssey calibration, making it easy to identify room problems.
• Edit the Audyssey target curve for each channel pair to suit your tastes.
• Adjust the EQ frequency adjustment range for each channel pair.
• Switch between 2 high frequency rolloff target curves.
• Enable/Disable midrange compensation to make the vocal region brighter or smoother.
• Save and load calibration results.

With the convenient front panel USB port, you can connect a USB drive and listen to files from MP3 all the way up to high resolution DSD (2.8/5.6 MHz), and lossless FLAC lossless (up to 24-bit/192-kHz). 

The high quality speaker terminals feature multi-way connection capability to handle a number of speaker cable terminations including banana plugs. They’re also color coded for correct hook-up, with matching color-coded labels for your speaker cables supplied.

Four Quick Select function buttons on the front panel and the remote control let you choose your favorite sources: each one remembers your preferred set-up and sound mode for that source, and you can even use them to store favorite Internet radio stations.
