    Denon Launches Its X6400H and X4400H AVRs; Promises HDR Updates for Legacy Gear

    (Denon) The new AVR-X6400H

    (September 18, 2017) Denon recently released details about two new high-end Network AV Receiver models, including its new flagship AVR-X6400H. Much like Sound United’s other popular receiver brand, Marantz, Denon’s two new AVRs are locked and loaded with HEOS whole-house music playback functionality and support for Amazon Alexa’s Smart Home Skill for Entertainment Devices (which officially becomes available on September 19, 2017). That means owners can use voice commands to operate a variety of controls on either AVR, including power functionality, volume control, initiation of playback, and source input switching.

    One of the bigger tech inclusions on both models is support for Dolby Atmos, DTS:X, and Auro-3D immersive audio codecs out-of-the-box. Past Denon models carrying onboard Auro-3D capabilities required an additional fee to unlock Auro functionality (that’s no longer the case). Despite the fact that Auro-3D is lacking in the disc-based movie content department, the technology does carry its own up-mix feature that allows it to playback native Dolby encodes.

    Denon’s new flagship AVR-X6400H ($2,199) is a true 11.2 channel receiver, possessing enough onboard power output to drive a true 7.1.4 immersive sound show (or 5.1 Bi-Amp setup) without any outboard help (140 Watts per channel, 8 ohms, 2-ch driven). The company says performance and sound quality is boosted by an amplification stage that uses a monolithic design with custom transistors. Those owners choosing to use an external amplifier can do so by tapping 11.2 channel preouts.

    Other key features include three HDMI 2.0 outputs capable of producing simultaneous images on two different devices, as well as a Zone 2 video device. Also, the inclusion of eARC allows immersive audio (Atmos/DTS:X) playback from TV apps through a singular HDMI cable.

    The step-down AVR-X4400H ($1,599) is also a super strong performer, nearly equaling the capabilities of the X6400H. The biggest difference being onboard support of 9.2 channel playback (125 Watts per channel, 8 ohms, 2-ch driven). The X4400H does offer 11.2 channel processing, however, allowing owners to incorporate external amplification for true 7.1.4 speaker arrangements.

    Denon offers Audyssey’s MultEQ XT32 room correction, standard, on both receiver models. Dual-band 2.4GHz and 5GHz Wi-Fi, Bluetooth, Airplay, Ethernet and onboard compatibility with Spotify, Pandora, TIDAL, and Amazon Music (among others) is also included.

    Denon’s other recent announcement targets owners of 2015 and 2016 receiver models. The company says a September firmware update will unlock Dolby Vision pass-through as well as HLG compatibility, boosting those receiver’s High Dynamic Range functionalities. The firmware can be downloaded wirelessly to qualified models.

      That's great news I hope my X4200 qualifies for DV and HLG.

      Pretty good chance the answer to that is yes.... the X4200 had a North American update earlier this year. I'd say that bodes well for you!

      You might have... unless that was firmware from earlier this year that you hadn't downloaded. Denon keeps a log on their website, so it wouldn't be too hard to confirm.

      How can we find out what firmware has the DV passthrough? Denon website has no info on firmware.

      It should be a new update as I have it set to auto update and I know I have manually checked in the last 30 days to ensure it was up to date. The last update per Denon website was March.

      You have a 3300 ? Cause it will be differant each model.
      Also I noticed something different...under the firmware was a DTS version.....is this new or have I just been ignoring it?
      Firmware 8500-5946-9141
      DTS Version 3.90.35.00

      PS I find it annoying Denon website requires you input serial number to view firmware updates.

      I have the x4200. The DTS one is the same as yours but my firmware is different. I understand your avr is different but won't the firmware be the same if it's for DV?

      No. They are typically differant due to variety in hardware and features. I have 3 Denon receiver and they all have differant firmware versions.

      Thanks for the link. My avr says latest. The Denon site says the latest was in April this year. I wish it would tell you what the update was about. I'm sure the DV hasn't been added to mine yet since it's suppose to update this month.

      Since your latest was March expect the DV to update this month hopefully if your avr qualifies. My latest update was in April so I hope mine updates this month too.

      @Todd Anderson do you know if the X6400 will do 13 channels with preouts or is it just 11 with or without preouts.

      I wonder if my X4300 had that update already. A couple of nights ago, I noticed that my X4300 started updating while in stand by mode. After 20 minutes, it say Update Complete on the front LED screen.

      Hmmm... the X4300 had a May update posted. They haven't officially posted the new update (but perhaps they're late modifying their update list)

      Looks like they're a little delayed on the release... I'm talking to a rep today, so I'll inquire.

      Sounds like the engineers had to delay the release to clean up a few lingering issues. Hopefully I'll have a new release date for you guys soon.
