Denon AVC-X6700H Review

Denon AVC-X6700H 11.2-Channels AV-Receiver With HDMI 2.1 And DTS:X PRO

Denon AVC-X6700H is the AV amplifier delivers 11.2 channel sound with up to 205 watts per channel, HDMI 2.1 including 8K processing, 8K upscaling, and the new DTS: X Pro

Finally, there is comprehensive information about the new AV amplifier AVC-X6700H from Denon (1). As already suspected in our preliminary reports, it is an 11.2-channel receiver (205 watts max) including 13.2 signal processing. 3D sound formats such as Dolby Atmos, DTS: X, IMAX Enhanced, or Auro-3D can be played in a 7.2.6 or 9.2.4 setup.

And we are already in 3D formats, the Denon AVC-X6700H (besides the AVC-X8500H introduced in 2018) is the only model that also the new DTS: X Pro mastered. The AVC-X8500H also inherited its DSP audio processing, which consists of two high-quality DSP chips with SHARC + cores. With front-wide support, the front channels can be expanded by two additional speakers to support the most important channels with 9.1.2 or 9.1.4 sound. Add to that the Dolby Height Virtualization and DTS Virtual: X, which actually completes the 3D segment.

HDMI 2.1 With 8K Upscaling In The Denon AVC-X6700H

HDMI 2.1 is included, as with the other Denon 8K devices. Like the AVC-X4700H and AVC-X3700H, the model is equipped with an HDMI 2.1 input and two HDMI 2.1 outputs (+ 1 HDMI 2.0 output). The remaining 7 HDMI inputs are version 2.0. All HDMI interfaces are equipped with the new copy protection protocol HDCP 2.3. This means that the AVC-X6700H can process 8K / 60Hz and 4K / 120Hz content.

There is also full HDR equipment with HLG, HDR10, HDR10 + and Dolby Vision. These can be passed on to compatible devices via pass-through. Video signals that are not available in sufficient resolution or refresh rate can be upgraded to 8K / 60p using the upscaling function.

The exterior of the model hardly differs from its predecessor. The front is unchanged, there is only one indication that the front HDMI input also supports HDCP 2.3. It gets more interesting anyway on the back. Here we not only find the mentioned HDMI 2.1 / HDMI 2.0 connections, the entire connection panel also looks a bit equalized and tidy. For example, the “Height3 / Front Wide” connections were placed one row above the predecessor.

The pre-outs and Zone2 / Zone3 cinch connections have been rearranged, as has the audio-in and component-video in / out. Everything looks a bit “airy”. The AV amplifier provides an active section for 11 channels .However, the preamplifiers can process 13.2 channels, with the subs not really getting their own signal. However, you can adapt and measure the subs yourself, which can bring advantages. The power consumption is specified with a maximum of 750 watts.

Features For Gamers

The AVC-X6700H will be high on gamers’ wish lists. With its HDMI 2.1 connections, the technical capabilities of the new PlayStation 5 and Xbox Series X consoles is great.

To enable the best picture quality for games, the AV amplifier also supports the HDMI 2.1 features VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), eARC (enhanced Audio Return Channel) and QFT (Quick Frame Transport).

In the future, games will also be played more and more often with 3D audio – another point that should not be neglected.

With extensive multi-zone support, someone can whack the gaming sound in the living room while the partner in the other room relaxes with classical music. A total of three such zones can be set up.



The range of functions is also excellent outside of video and audio processing from HDMI sources. Music can be played as high-resolution audio in various formats (ALAC, FLAC, and WAV with up to 24-bit / 192 kHz). Streaming services such as Spotify, Amazon Music HD, TIDAL, SoundCloud, etc. are just as much part of the range of functions as the in-house HEOS multiroom audio streaming. When it comes to audio streaming, direct audio output via Bluetooth (headphones, speakers, soundbar) should also be mentioned.

We also have streaming via WiFi, Apple AirPlay 2, Roon and voice control via Google Assistant, Amazon Alexa, and Apple Siri.

The Denon AVC-X6700H is “grooved” with the calibration microphone included in the scope of delivery and the integrated MultEQ XT32 automatic calibration system. In the future, two measuring points can also be saved. The user can switch between two measurements, perfect for large rooms with different seating options.
