About Denon AVC-X3700H 8K Home Theatre Amplifier

Technology marches on and, despite the sad state of the world’s health at the start of the new decade, the state of the AV world’s technology is looking mighty impressive. The resilience of the human race knows no bounds and we take our hat off to all the engineers and designers and manufacturing people who have worked so hard to make this great home theatre receiver a reality.

There are quite a number of improvements that the AVC-X3700H brings to market that keep it at the front of the pack. These new features are fleshed out in the text below but here is a summary of the main changes.

Denon AVCX3700H Network Surround Amplifier

The first thing the eagle eyed amongst you may have spotted is that the model has changed from an AVR to an AVC designation. This means there is actually no terrestrial radio on board such as AM/FM or even DAB+ Radio. These days, internet radio is the way to go, offering all your local Australian stations but opening up the whole world of international radio so you can browse whatever country or style of music takes your fancy.

There is now support for Dolby Atmos height virtualisation which means you don’t need actual height speakers to experience height sound which is pretty cool. DTS:X now supports up to 7.1.4 channel surround sound. New standards supported are HDR10+, Dynamic HDR, QMS, VRR & QFT – see more details below. The AVC-X3700 has video signal passthrough and upscaling up to 8K & Bluetooth headphone transmission – very convenient. HDCP 2.3 makes an appearance, there are 6 analogue line level inputs, up from 5, and Bluetooth has been upgraded from version 3.0 to 4.2.

A Closer Look At The 'X3700H

The Denon AVC-X3700H delivers the ultimate home theatre experience with 8K/60Hz pass-through and upscaling, 4K/120Hz pass-through, as well as support for the latest HDMI specifications. The AVC-X3700H lets you build the best 4K home theatre today and gives you the comfort of knowing that your AV receiver is 8K ready when you are. Enjoy the highest quality 3D audio and video for even the most demanding entertainment needs.

Powerful 9-Channel Amplifier with the Latest Home Cinema Specs: Featuring discrete, high-current amplifiers on all channels, the AVC-X3700H delivers high-power performance of up to 180 Watts (peak) per channel. Low impedance drivers provide operational stability for a wide range of speakers for balanced, tonal sound. Upgrade your expectations in home theatre entertainment.

Full 3D Audio Support: Immerse yourself in 3D audio with Dolby Atmos, Dolby Atmos Height Virtualisation Technology, DTS:X, DTS Virtual:X, IMAX Enhanced and Auro-3D. Set up a 5.1.2 or 7.1.2 Dolby Atmos surround system using Dolby Atmos elevation speakers, or dedicated overhead speakers, for the ultimate home theatre experience. DTS:X gives your movies, games and music a realism unmatched by traditional 5.1 surround sound. Dolby Atmos Height Virtualisation Technology and DTS Virtual:X provide immersive audio without height channels, creating virtual height effects in a 7.1, 5.1 or 2.1 speaker arrangement.

Advanced 8K HDMI Video Section: Enjoy your favourite movies, shows and games with the best picture quality available. The AVC-X3700H features an advanced HDMI section (7 in/3 out) with a dedicated 8K input that will support 8K/60Hz and 4K/120Hz video pass-through. All HDMI inputs feature 4:4:4 Pure Colour sub sampling, HDR10+, Dolby Vision, Hybrid Log-Gamma (HLG), and BT.2020 pass-through support for exceptional colour, clarity and contrast. Enjoy 8K upscaling as well as HDCP 2.3 processing to play copy-protected content uninhibited.

Brilliant Colour – Universal Compatibility, HDR10+, Dynamic HDR: The AVC-X3700H supports High Dynamic Range video formats, HDR10+, Dolby Vision and HLG (Hybrid Log Gamma).

About Denon

As Japan’s first audio electronics manufacturer and with a deep legacy of firsts, Denon is absolutely one of the longest audio company emanating from Japan. Founded in 1910, their aim has always been to enable the entertainment moments that matter through the relentless pursuit of quality, innovation and audio performance and Audio Trends teamed up with Denon way back in 1982. Even then, we had difficulties keeping up with demand because they just couldn't physically reproduce enough gear for the world market! How have they been so successful over decades and still are up with the best in mass-produced audio components when the market has become very crowded? 

Innovative engineering and technology are at the core of what makes a Denon product so iconic. Through a disciplined approach to design and production, their Japanese based engineers ensure that only superb craftsmanship, precision engineering and impeccable performance go into every component. The creation of products that can deliver total quality enjoyment to others is a fundamental driving passion and the main reason why they exist. What’s more, their constant quest to create the perfect entertainment component is the key to transforming creative ideas into leading innovation, and to anticipating consumer needs. In recent times, this has included the development of mobile technologies, so that customers can enjoy the best possible quality reproduction in any format. 

For everyone at Denon, Passion, Artistry, and Technology are more than buzzwords – they are part of the quintessential philosophy behind everything they do. These three elements and decades of innovation and engineering excellence have shaped their entire culture. Every detail of a Denon product is crafted around these elements with a single goal in mind: to maximise the entertainment experience. It is worthy of note that Denon is distributed in Australia by Sound United who are the international owners of the brand so after-sales-service is readily available if required.

Our Take On The AVC-X3700H Surround Amplifier

It looks like the Denon AVC-X3700H will take over the mantle of its predecessor to become the go-to AV amplifier at its price point. It won the What Hi-Fi? 2020-2021 award for the best AV Amplifier £750 - £1500 (A$1500 - A$3000 approx). It really does give very little away to the heavy hitting AVC-X4700H and AVC-X6700H home theatre receivers and could represent the pick of the range. With enough features to satisfy almost all your tech needs and enough power to drive the majority of speakers, we can see the Denon AVC-X3700H finding itself taking up residence in a lot of happy homes around Australia and forming the basis of some incredible home theatre systems. Give us a call to see if it is the best for your needs.
