• Class G amplification for impeccable sound and efficiency
• 90W of power per channel
• 5 analogue inputs including phono
• 3 digital inputs
• 32-bit DAC,Sabre ESS9038K2M
• Full I/P control
• Total harmonic distortion + noise = 0.003%

There are two frequent problems with hi-fi amplifiers. Class A, the traditional audiophile’s choice, uses a single power supply constantly running at full capacity, even when there’s no signal coming through. Great for reproducing those subtle details at low levels however struggles to provide extreme power when needed.

Class A/B, the most common amp class, switches between the two internal amplifiers, one for each half of the waveform. Far more efficient but often a recipe for crossover distortion, since those low-level details we crave can get lost within any mis-match between the two switching over.

Class G is essentially a hybrid amplifier, utilising Class A specifically for low-level signals, but when required switching in an additional power supply to power those larger sections of the waveform.

First Impressions

If youʼre impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression. The subtly curved aluminum/glass resin front panel adds a sophisticated touch that complements any décor.  The central porthole display reflects iconic Marantz designs of the past while it brings you an "at a glace” view of the amplifierʼs operating status.

Choose from a variety of internet radio stations and listen to your favorite tracks from music streaming services like Spotify. You can also listen to songs from DLNA PC or Mac. The AVR-X3100W is equipped with two RF antennas for optimal quality receiving Bluetooth and WiFi.

The advanced video processor AVR-X3100W can treat future 4K Ultra HD 60 Hz full rate content and features 4: 4: 4 Pure Color 4K sub-sampling pass-through, features the specifications of the latest HDMI. The AVR-X3100Weinai also certified by the Imaging Science Foundation for video quality and is equipped with a full suite of advanced video ISFccc calibration checks.

The part of the powerful 7-channel amp has a final design support multiple high-power output devices on all channels. With 180 watts per channel, the AVR-X3100W can also lead loads of low impedance, up to 4 ohms. Our new Eco Mode allows reducing the overall energy consumption and has Eco Meter on the screen, allowing you to see graphically the reduction of energy consumption in real time.

With the Gold suite of Audyssey audio processing DSP algorithms, the AVR-X3100W features Audyssey MultEQ XT automatic metering and correction of room acoustics, along with Audyssey Dynamic Volume and Audyssey Dynamic EQ. The Audyssey DSX (Dynamic Surround Expansion) gives you the option of adding more front speakers or front wide-angle speaker.


8 Inputs HDMI, 2 HDMI Outputs
Equipped with not fewer than 8 inputs HDMI, the AVR-X3100W has 7 HDMI inputs on the back panel, along with another HDMI input on the front panel, allowing you to easily connect your favorite gaming console, HDTV camcorder or other HDMI device. The 2 HDMI outputs support various program sources, so you can enjoy surround movie in the main room and a separate stereo program with video from a different source in a second room.

Built-in Bluetooth, Built-in Wi-Fi and AirPlay, DLNA
Many portable devices are equipped with Bluetooth wireless connectivity, and integrated Bluetooth wireless connectivity AVR-X3100W allows you to make streaming of your favorite audio tracks from up to 8 Bluetooth devices such as smartphones, portable audio players and tablets. With integrated Wi-Fi wireless technology, your AVR-X3100W connected to the Internet through your home network, opening a world of music from Internet radio stations, as well as in streaming Spotify subscription service through the last scene Association Spotify. With AirPlay, you can enjoy listening to your favorite tracks wirelessly from your portable iOS device, including iPhone, iPod touch and iPad. Certification DLNA 1.5 allows you to connect to a PC or Mac via your home wireless network for additional features streaming. Our Denon Remote App lets you easily check the AVR-X3100W with your favorite portable device and is available for Apple and Android devices and the Kindle Fire.

Easy to Install, Easy to Use
Exclusive Installation Guide Denon, together with our Introductory Handbook, ensures proper connection of your system easy and quick configuration, so you can enjoy perfect surround sound home theater system with minimum disruption and difficulty. The Installation Guide has sharp graphics and text, guiding you quickly and easily in the installation process, optimizing critical system settings for the best possible sound quality.

Powerful Amplifier 7-Channel Discrete Reinforcement Layout with Eco Mode
With maximum power channels of 180 watts each, the AVR-X3100W final design features support multiple high-current output devices with identical circuit topology for all seven channels. Our new Eco Mode allows reducing the overall energy consumption and has Eco Meter on the screen, allowing you to see graphically the reduction of energy consumption. The Auto Eco mode automatically switches between normal energy consumption and Eco modes, depending on the selected volume level. The final portion of aid may lead loads low-impedance until the 4 ohms, for compatibility and stability with almost any speaker model.

Built Audyssey MultEQ XT
The AVR-X3100W has the Silver family of DSP technologies Audyssey, including MultEQ room acoustic measurement and correction. Through the supplied measurement microphone, the MultEQ system first measures the actual response inside the room from all the speakers including the subwoofer, and then create multiple high precision digital filters that ensure smoothest response. The AVR-X3100W also has the option of Audyssey MultEQ Pro.

Top audio formats
The advanced audio decoding section includes recent high-resolution non-losses decoders, including Dolby TrueHD and DTS-HD Master Audio. There are also three additional audio decoding options to extend the front or on the sound stage, termed Dolby Pro Logic IIz, DTS Neo: X and Audyssey DSX.

2 Outputs Subwoofer
Depending on the position the subwoofer in the listening room at the listening position, the quality of deep bass can be adversely affected by reverberations inside the room, with sharp peaks and wells which, together, produce muffled bass and fuzzy bass details . Equipped with 2 subwoofer outputs, the AVR-X3100W lets you use 2 subwoofers, arranged in different positions in the listening room. Having subsse two different positions in the room, the quality of bass can often be significantly better thanks to the resultant response with smoother, deeper bass free from annoying steep peaks and dips.
