Features

The AVR-X6400H is equipped with 11 discrete gain channels. Also supports DTS: X, and Dolby Vision HDR. Its output powers is 145W at 4 Ohms. Enjoy the most complete surround sound experience using the latest Dolby Atmos, DTS: X and Auro-3D audio formats. The great thing is that 11-channel amplification allows you to adjust 3D effects up to 7.1.4 configurations without the need for an additional external amplifier. DTS Virtual: X brings the ultimate in immersive sound experience, regardless of the number of speakers installed. Even with two speakers, you will hear sounds from above and from the side.

Design and build

The brushed metal finish looks very impressive, and all the inputs and buttons on the front panel are hidden. The 6400H is equipped with a clear, informative display and a large compact remote control. Unfortunately, there is no proper backlight. Proper Denon tuning is crucial: it is equipped with a microphone for automatic calibration and can optimize sound for your room's acoustics and speaker configurations. On the streaming side, Denon-equipped Wi-Fi supports high-definition streaming video up to 24 bit / 192 kHz and plays DSD files.

Connectivity

All eight HDMI inputs (and three outputs) are HDCP2.2 certified, meaning they will play Ultra HD 4K and HDR content in full. Along with the generous addition of HDMI ports, the 6400H comes with several analog and digital connections. The receiver even has an MM background input.

Setup

Fortunately, the Denon menu is beautifully laid out and easy to navigate, so there is no need for any help, even if you are new to AV.

Pros and Cons

Pros

  • Denon has a mode for Dynamic EQ which allows a rich sound even while listening at low volume so you don't wake up the entire house
  • During the setup, the receiver informed me that my Sub was too loud
  • Even when listening at higher volumes I don't notice any shrill highs or imbalances in performance. It makes my entire system sound better than ever

Cons

  • The only con I have about this receiver is that the remote is not back-lit
