We have tested the Denon AVC-X6700H home cinema receiver!
Denon is a more than 100-year-old Japanese brand that has been designing and manufacturing hi-fi and audio devices since 1910. The Denon brand is a guarantee of quality and perfect sound. They have won and are winning several awards, constantly striving to meet the needs of audio fans with the best products.
Available in silver and black, it fits into any style of room with its modern, aesthetic look. The large display on the front panel is easy to read, the inscriptions and information appearing on the surface are perfectly visible even from a distance of 3-4 meters. There is also a USB port on the front panel in addition to the standard control buttons.
The amplifier has a number of inputs and outputs, including 8 HDMI inputs, 3 HDMI outputs, all of which are HDMI 2.1 certified. The AVC-X6700H also supports 8K up to 60 Hz and 4K up to 120 Hz, as well as HDR10, HDR10 +, HLG, Dolby Vision, and the latest 3 Ds formats, including Dolby Atmost, DTS: X and DTS: X Pro. (The latter is responsible for 13-channel signal processing.) You can’t miss the Phono input to play traditional vinyl records. With 2 12 V trigger outputs, 2 coaxial and optical digital inputs, 2 component video inputs with 1 output, 4 composite video inputs with 2 outputs. It is also equipped with 6 stereo analog inputs, for zone 2.3 RCA stereo analog output, FM / AM, RS232 connectors, Ethernet connection and IR input and output. The maximum power consumption is 750 Watts.
The remote control is large and has many buttons, it is easy to see and very good quality.
AVC models do not have a built-in FM radio, unlike AVR models.
Thanks to the IMAX Enhanced program, top image quality is guaranteed. Various settings are available with VRR (Variable Refresh Rate), ALLM (Automatic Low Delay), QFT (Fast Image Transmission), and WCG (Wide Color Gamut). With the help of the multi-room wireless system, HEOS can be used to create a centrally controlled wireless system located in different rooms within a building, so we can control the sound system from Android or iOS mobile devices via a WiFi connection. Various voice control features are also available, such as Amazon Alexa, Google Assistant, SIRI, or JOSH. With Roon Testeo, you can transfer music to your Mac or Windows PC. There is no barrier to online music streaming, you can also listen to music from Spotify, Deezer, Sound Cloud, Tidal, Apple Music, or AirPlay2 apps.
32-bit AKM D / A converters perform the function of converting digital signals. AL 32 signal processing (high definition filtering) is responsible for the sound quality. 2 dual SHARC and core DSP chips drive the device. Dolby Height Virtualization and DTS Virtual: X are also among its features. The Audyssey MultiEQ XT32 Room Correction System measures using the included measuring microphone and makes adjustments based on it. For the AVC-X6700H, this program is complemented by Sub EQ LIT and LFC for fine tuning, which requires the Audyssey MultiEQ Editor. (This application, during testing, set the subwoofer level too low by about 13 decibels, this had to be corrected.) ECO (Power Save Mode) adjusts the power consumption to the current volume. The Control 4 system is quick and easy to install thanks to the Simple Device Discovery Protocol (SDDP) drive.
Room correction systems can only achieve real improvement in sound in rooms with adequate acoustics. This is because these programs only measure the sound pressure and perform calibrations against it. Thus, reverberation and echo problems are also treated as sound pressure problems. If the sound pressure is further reduced, the sound will deteriorate instead of improving. More advanced DCR software improves sound clarity and dynamics by controlling phase and pulse transmission, but they can’t really do anything about reflections. However, if we take care of the walls, ceiling and window surface of the room with sound-absorbing and diffuser panels, the room correction systems will further improve the sound with smaller corrections.
The Denon amplifier was tested in a living room of about 30 square meters, paired with Klipsch R620F floorstanding speakers and Klipsch R-120SW active subwoofer. The acoustics of the living room can be said to be quite good, broadband panels were placed on the walls, and bass traps were placed in the corners next to the speakers. Based on our acoustic measurements, a few more diffuser elements will be needed for perfect acoustics, which will need to be placed at the reflection points we have established.
We started our test with Harry Potter and The Order of the Phoenix. The receiver produced a very nice, clear, understandable sound, and the dynamics and detail were flawless. Maybe the bass could have been a little more intense.
We watched the action-packed comedy, Fast & Furious: Hobbs & Shaw, afterwards. We got a very precise, detailed sound, we had a realistic, spatial experience. The bass ranges were slightly reduced here as well, but the subwoofer compensated for this little thing.
The Denon amplifier performed really convincingly during the rehearsal. Detail, excellent dynamics and accuracy, clear and understandable dialogues, can be characterized by lifelike, spatial sound. The bass could be better, but with a high-performance subwoofer and speakers, that will be fine too. Room acoustics are very important if you really want optimal sound, so be sure to treat the walls and ceiling of your room, because we can only take advantage of the Denon Audyssey room correction program if the reverberation time is right and the echoes are eliminated.
