Denon AVR-X3400H Review

Denon’s fifth-generation AV receiver AVR-X6400H, AVR-X4400H, AVR-X3400H, AVR-X2400H, and AVR-X1400H have received the attention of many audio-visual enthusiasts since its launch. Today we are going to introduce Denon’s fifth-generation main product: AVR-X3400H!

Why is AVR-X3400H the main product of Denon’s fifth generation? Because audiophiles who know audio-visual products know that in addition to Bluetooth and wireless multi-room audio, the most important thing is the power of the amplifier and the number of channels.

To experience the next-generation audio-visual experience brought by panoramic sound, a minimum 8-channel configuration (5.1.2) is required. The increase in the number of channels means that the power amplifier needs to output more power.

And low-end products because of insufficient power, it is challenging to push 7 channels (many subwoofers are active and do not require power amplifiers). While the power of the high-end product is sufficient, but the price is also prohibitive. The Denon AVR-X3400H receiver is a cost-effective product that meets the audio-visual requirements of most audio-visual enthusiasts but is also relatively affordable.


Denon AVR-X3400H double-layer packaging. Manuals, remote controls, Audyssey kits, etc. are all available. Besides, Denon also provides a simple paper tripod for the Audyssey calibration.

What is Audyssey

In 2002, the Audyssey laboratory was separated from the University of Southern California. Audyssey spent 6 years and invested 6 million US dollars in researching how to improve the sound effect and made a significant breakthrough in audio equalization technology. In 2004, his research results Audyssey MultEQ was first applied to the home theater Receiver (Denon’s flagship AVR-5805, which was priced at $6,000 at the time) negative impact of the indoor acoustic environment on sound reproduction.

Denon Audyssey Calibration

Audyssey has developed a variety of audio calibration products to overcome the limitations of environmental acoustics on audio systems to match human hearing and perception better. They have been used in many consumer, professional, and car audio applications.

Design and Functions

The body of the AVR-X3400H is made of metal and has a good texture. The large, eye-catching display on the front panel can clearly display information such as volume, input format, and channels. At the bottom right, there are interfaces for testing Audyssey microphones, an HDMI port, and a USB port. It is very convenient to use temporary external devices.

AVR-X3400H adopts a 7.2 channel design with fully separated amplifier technology. This means that each of the seven channels of the AVR-X3400H can obtain a maximum power of 215W (test conditions: 6 Ω, 1 kHz, THD 0.7%, 2ch drive). Denon’s unique Auto Eco mode automatically adjusts the maximum available power according to the volume in real-time, reducing household energy consumption.

Besides, the built-in 7.2 channels fully meet the requirements of Dolby Atmos and DTS:X. Audyssey MultEQ XT32, setting and optimization are more precise. SubEQ HT is used to integrate multiple bass woofers, simplify the setup process, and obtain smoother and more complete bass. Audyssey LFC (low-frequency calibration) can be turned on to achieve powerful bass in the room while controlling bass leakage not to disturb neighbors.

Denon AVR-X3400H av receiver comes with 8 HDMI inputs, all supporting 4K/60 Hz full-rate, HDCP 2.2, HDR (high dynamic range), BT.2020, wide color gamut, etc. It can connect to all the latest devices, such as game consoles, Blu-ray players, or streaming set-top boxes.

Quick Guide for the AVR-X3400H Installation

As Denon Receiver has an Audyssey function, the installation of AVR-X3400H is straightforward. Basically, you can set it to step by step according to the program steps. Here are the main points:

(1) After inserting the 3.5 audio plugs of the test microphone into the test SETUP mic port on the front panel, the Audyssey setting menu will appear on the screen. In the configuration menu, check the corresponding options according to the actual speaker layout.

(2) Complete the microphone test in 8 positions in strict accordance with the program requirements.

(3) After the test is over, the amplifier will ask whether to turn on EQ XT, Dynamic EQ, and VOLUME. The first two are recommended to be turned on.

(4) In the final configuration, manually adjust the speaker size attributes and set them to small. And hand over the bass below 110HZ to the subwoofer for processing. The cut-off frequency of the principal and middle speakers is 80Hz. The subwoofer is set to LFE mode, and the crossover point is 110Hz.

Movie Performance

“Wonder Woman” is the latest Doby atmos Blu-ray movie. Many fighting scenes in the film have a perfect sense of envelopment. Except for the surrounding space before and after, the top surround gives a lot of upper sound effects. Driven by AVR-X3400H, the sound is extremely fast and transient, and the sound of different weapons can be truly restored. X3400H can accurately reflect the orientation of each weapon, and the explosion scene is compelling and shocking!

Although “Guardians of the Galaxy 2” is not the soundtrack of Atmos, there are many dialogues between different characters in the film. The AVR-X3400H’s voice is real, with clear, three-dimensional images, just like the characters in the movie are right in front of you. The drive of the subwoofer is very sufficient and full of flexibility.

The production cost of “The New Mummy” is not low. The Blu-ray movie version of this film is also produced by Atmos. Actually, it sounds like there are many large-scale scenes in the movie, which are very demanding challenges for power amplifiers and speakers. But the Denon AVR-X3400H still achieved a high level of performance. Each intense scene has an affluent amount of information, creating a dynamic 3D space and directly conveying the film’s tension and fear to the audience.

Symphony Performance

We especially chose the 2017 Vienna New Year Concert. The overall style and tone of this concert still maintain the tradition of German and Austrian classical concerts. The warm strings and bright brass music, driven by the AVR-X3400H, have distinct levels and maintain relatively good strength in the low and mid-range frequencies. The high frequency is rich in gloss. Classical music fans will be taken over by Denon’s style.
