”A surprisingly big improvement on its already excellent predecessor, the AVC-X3700H could well be the performance-per-pound pick of Denon's 2020 range.” ’What Hi-Fi?’ 2021 Product of the Year.

9-channels deliver your choice of surround sound

Thanks to the flexibility of 9.2-channel amplification, the AVC-X3700H delivers a wide range of surround sound formats. Choose between 7.2.2 or 5.2.4 Dolby Atmos speaker configurations with two or four ceiling speakers. Alternatively, stick with 5.2.2 and power a second pair of speakers in another room or bi-amp your main pair of speakers. As your system grows, so the capability of this Denon AVC grows with it.

Optional 11-channel sound for full immersion
Add an extra stereo power amp and the Denon lets you configure four ceiling or Atmos-enabled speakers as well as full 7-channel surround sound. Alternatively, use two Atmos speakers and enjoy a broad soundstage with 'front wide speakers' forming a 9.2.2 system. If you don't fancy a Dolby Atmos specific system but want the most immersive sound possible, go for an 11.2 configuration. This offers 7.2 sound with the addition of front width and front height speakers.

The magic of Dolby Atmos and DTS:X
Dolby Atmos and DTS:X use ceiling or up-firing speakers for three-dimensional and fully immersive sound. Whether it’s rain falling in a tropical jungle or the intense sound of overhead gunfire, Dolby Atmos and DTS:X put you in the centre of the action.

Certified for IMAX Enhanced
A partnership between IMAX, DTS and award-winning Hollywood sound mixers delivers a stunning new sound format – IMAX Enhanced. Only the highest quality home cinema equipment meets the standard, with IMAX enhanced content available on HDR streaming and UHD Blu-ray disc.

Extra height, without the speakers - Dolby Atmos Height Virtualization and DTS Virtual:X
As impressive as Dolby Atmos and DTS:X sound, it’s not always possible to accommodate the extra speakers. Dolby Atmos Height Virtualization and DTS Virtual:X Height Virtualisation technology go some way to help fix. Play any Dolby format and enjoy a more immersive sound with virtual height enhancement – using your existing speakers. DTS Virtual:X also creates a more enveloping sound from any DTS codec. Compatible with 2.1, 5.1 or 7.1 speaker configurations, DTS Virtual:X gives the impression of height and immersive sound.

Ready for 8K, with dedicated HDMI input
Featuring a dedicated, 8K compliant HDMI input and matching output, this premium Denon AVC is ready for the next generation of TV. Not only does the amp pass through 8K/60Hz signals, but it also upscales HDMI signals to the 8K standard, too – helping you make the most of your 8K TV with 4K UHD media. If you’ve not yet made the jump to 8K TV, the socket also handles up to 4K/120Hz signals, for the highest quality pass through and upscaling with 4K UHD.

Supports Dolby Vision, HDR10+ and Dynamic HDR
Equipped with a comprehensive 7 in/3 out HDMI interface, the AVC-X3700H also supports a wide range of High Dynamic Range video formats. These include Dolby Vision, HDR10 and HLG. It also supports HDR10+, which enhances picture realism by sending dynamic Meta data to your TV, as well as Dynamic HDR. In short, whatever the format used by the film, game or stream, the Denon supports it.

Serious about gaming
The latest HDMI support also marks a big improvement in gaming. 4K/120Hz and VRR (Variable Refresh Rate) support maximise resolution and clarity. Quick Frame Transport (QFT) and Auto Low Latency Mode (ALLM) help eliminate lag and frame tearing, giving you a smoother, more responsive gaming experience.

Now works with all the voice assistants
The AVC-X3700 adds Siri and Google Assistant to Alexa, making it more widely compatible with voice assistants than before. For Alexa or Google Assistant control, simply download the HEOS app. Pair your Echo device if you’re using Alexa and you’re good to go – adjust the volume, skip to the next track and switch inputs simply by asking Alexa or Google. For control via Siri, simply link the amp via Apple AirPlay 2 and enjoy voice interaction and AirPlay 2 multi-room support.

Advanced multi-room functionality and custom install ready
The AVC-X3700H has three HDMI outputs with an independent zone 2. This means you can run audio and video to another screen, in another room independently from the twin, main outputs. IP control capability for major third-party control devices, as well as Control4 SDPP (Simple Device Detection Protocol) certification plus a DC trigger makes this AV amp ideal for home installations.

HEOS built-in - for the finest multi-room audio
HEOS multi-room music systems connect together by dual-band Wi-Fi, making them easy to set up with your existing home network. Up to 32 HEOS units can be set up at one time, ensuring even the largest of homes are covered for multi-room music. With HEOS already built-in, the AVC-X3700H is ready to go as a single 'zone' without any further adaptors.

Control it all with the HEOS app
Once you've set up your HEOS speaker system, you can stream music effortlessly via the dedicated HEOS app. Available for Apple iOS and Android, the app not only lets you stream your stored music but also Internet radio services and popular streaming services such as Spotify, Tidal, Napster and Deezer.

Bluetooth, AirPlay 2, and built-in wi-fi for the complete networking experience
With both Bluetooth and AirPlay 2 connectivity it's easy to connect all your smartphones, tablets and compatible lap/desktops and stream music wirelessly. The AVC-X3700H also comes with wi-fi and Internet radio. Simply connect to your home network via Ethernet or wi-fi and access thousands of Internet radio sites via vTuner as well as subscription services such as Spotify Connect (requires Spotify Premium account). A Bluetooth headphone output is now also standard.

Audyssey MultEQ XT32 for simple room set-up
Featuring Audyssey's high-end MultEQ XT32 technology, the AVC-X3700H adapts itself to your room's acoustics. The XT32 version of this automatic measuring and set-up device features include Audyssey Dynamic Volume, Dynamic EQ, LFC and SubEQ HT for total control. If you want to take this even further, purchase the MultEQ Editor App (at additional cost) and you've access to advanced user settings.

Quick Selects for the perfect sound – instantly
With such user flexibility, getting the perfect sound can be a complex business. For this reason, Denon has fitted the AVC-X3700H with four Quick Select audio presets. Take your time in setting the ideal sound balance for your TV, Blu-ray, games console and music source and recall them at the touch of a button for the ideal sound, instantly.

Get a more immersive home cinema experience, with the Denon AVC-X3700H.

Rated 5 out of 5 by from Great service I bought the unit a couple of weeks ago, now all setup for my 5.2 Teufel (they recommende matching receiver) cinema speakers and enjoying the system. Speedy delivery, probably too speedy as I requested a specific day for delivery and courrier was one day early. Cheers

Rated 5 out of 5 by from Denon AVC-X3700H After a long chat with Bradley at Southampton branch. I purchased this amp, and am very glad I did. Easy to set up, although the 312 page manual is only online, the sound quality is superb. Also, thanks to Bradley for his comprehensive help and patience with my questions about setup. Shame that the radio is only on the USA version, but have found Internet radio.

Rated 5 out of 5 by from Out performs high expectations Bought to replace an aging Onkyo AVR, largely to give flexibility to build a 5.1.4 atmos set up. That will follow next year, for now it’s 5.1 - but a massive upgrade on my previous 5.1 set up. It’s like night and day - wrap around, seamless integration of speakers, plus terrific clarity of sound (driving Dali Oberon speakers). I can’t wait to add in the atmos speakers to complete the set up! Overall very very pleased.

Rated 5 out of 5 by from Excellent customer service I recently bought the Denon amp and some in Wall speakers and I ordered the wrong speakers as my outer walls were not deep enough. A lovely man called Vik sorted everything. He arranged pick up of the speakers and found me some gorgeous Klipsch speakers instead. Everything was made stress free by Vik. Best customer service I have ever had. Give the man a pay rise. Just one of the many reasons I choose Richer Sounds.

Rated 5 out of 5 by from great amp - superb sound Excellent on-screen and on-amp displays. Audio set-up using the supplied mic is a little tedious, but it works well (except for setting some of my speakers 'large' rather than 'small' - but that was easy to correct). The surround effect from my 7 channels is superb - even from old films. The sound quality is bright and has taken my speakers to a new level. HDMI switching is quick but not problem free - my Humax Aura frequently re-boots - sometimes lose audio after switching inputs. But, I think generally HDMI devices may have got too clever for themselves. The Denon is still far better at switching inputs than one of its competitors that I recently trialled. Overall, a great bit of kit. So glad I bought it. And so glad I bought it from Richer Sounds, who's advice and help has been invaluable (Cheers Ash!).

Rated 5 out of 5 by from Denon - AVC-X3700H This isn't a review regarding the Denon AVC-X3700H (which is excellent by the way) It's a review regarding the customer service by the Leeds store, especially by Lee the assistant manager. His knowledge, patience and experience was first class. To quote the late great Stan Lee, hang loose, face front and make mine Richer Sounds Nuff said.

Rated 5 out of 5 by from Why spend more, this amp is a cracking bit of kit, I was torn between the 3700 and the 4700, however using my sensible head this unit was only going to be used to watch TV and Movies. After spending circa 30 minutes going through the setup, I am happy to report that the 3700 is astonishing! It’s powerful enough to illuminate my room (4.8m x 3.8m) with sound that is precise and well balanced. Thankfully I’ve not experienced any lip sync issues connected to the Apple TV 4K or my Blu-ray player which was a pleasant surprise. I’ve paired this amp to the monitor audio 200 ams bronze 6G speaker package and a SVS Subwoofer which all work beautifully together. I would also like to thank the team at Leeds especially the main man Chris, Joe and Ahmed.

Rated 5 out of 5 by from Denon 3700 Purchased this after my 15yr old denon expired. Wanted to add some extra height dolby atmos speakers to my 5.1 surround sound system and boy was it worth it. Now sounds better than at cinema when watching films. Had a scene were a helicopter circled a house and landed and could hear this from inside. WOW

Rated 5 out of 5 by from What a difference! A full sonic upgrade After chatting to Joe in telesales I ordered this receiver. My Sony STR-DN1080 was great but after buying some Focal Atmos speakers they lacked something. Joe has one of these award winning beasts and didn’t take a lot to convince me. Thanks to the current supply issues it took a while to get but when I did it was so worth it. It’s a totally different experience to the Sony. The sound is so detailed it gives you a new experience with tried and tested films and games. Try the bee hive scene on the 4K ultra disc of Bladerunner 2049 and it will blow you away. Richer Sounds were a pleasure to deal with as usual and I can’t recommend this unit enough. The Xbox Series X issue hasn’t bothered me as I use the eArc function and it detects Atmos no problem

Rated 4 out of 5 by from X3700H had to send the denon back, a fault with it, got a replacement 3700, so far all good, i also know the 3700 as a handshake issue, sometimes taking a couple of seconds for sound to come though, hopefully with firmware update it will solve it...apart from that great sound, and a good update on the 2600....thanks again for the richer sounds team...dave c

Rated 5 out of 5 by from Awesome sound I waited a few months for this amp, I've always had Yamaha, I found the on screen intimal setup menu for wiring up the Atmos speakers easy to follow and the microphone and test tone really easy. Highly recommend this amp if I have one complaint I wish all manufacturers would backlight the buttons when you watch movies in the dark.

Rated 4 out of 5 by from Excellent quality sound I updated my old projector and Reciever last week. Now have full 1080 quality with Sky and blueray and even better quality image on 4k Amazon fitrestick. Also find bluetooth music quality is very good and so much easier than old cabled system.

Rated 5 out of 5 by from Excellent sound. Love the network features. I’ve had the amp for a few weeks now and I’m really impressed. The sound is fantastic as you’d expect. The audyssey setup has managed integrate my sub with the rest of the speakers so much better than I ever managed manually.

Rated 5 out of 5 by from Great upgrade Was looking for an upgrade to my Surround Amp and also a Multi-room system for listening to Music. This unit covers it all. Setup very user friendly, also very easy to make ongoing adjustments via system interface. The peripherals are not cheap but so far worth every penny. Timing was great also as there was a deal on at Richer Sounds when I was ready to buy.

Rated 5 out of 5 by from Great Amplifier - Easy to Set up and sounds great I bought this a couple of weeks ago to replace an old Denon amplifier that gave up the ghost! I was a little hesitant to do so given that it was the same brand however the 6 year guarantee I was upgraded to tipped me over the edge to do so. This was an upgrade in-terms of age as well as from a circa £500 amp to £1000 (ish) ... worth the extra! details are there that weren't before!

Rated 5 out of 5 by from Mr Absolutely outstanding! I love my new Denon AVC-X3700. I was going to buy the Sony STR-DN1080 but it lacked features such as 8K and HDR+ etc and decided to push the boat out and so glad I did. Crystal clear sound, plenty of punch, looks the part too. I've got it connected to a high spec Sony TV, Bluray player and PS5. The picture through to the TV is perfect, sound awesome too. Next purchase is some new speakers when all the shops re-open.

Rated 5 out of 5 by from Brilliant Amp Did a lot of research as to what I wanted. Got in contact with the Newcastle branch & spoke to Anis. Great knowledge & he confirmed what I had hoped. It wasn't just the amp, it was a TV & cables as well. In an earlier review, I said 20 years, but looking back, it's actually 40 years I've been using Richer Sounds. That tells you something for satisfied customer loyalty. Keep it up lads.

Rated 5 out of 5 by from Denon AVR-X3700H Amazing AVR and lovely support from Richer sound. I did my research for nearly 6 months before making this first purchase with Richer sound. I'm new in UK and I had no idea how to proceed. They helped me with video call and looked around my living room. I'm still considering to buy more speakers from them.

Rated 5 out of 5 by from What a difference !!! After a telephone "consultation" with Richard at CHeltenham, I ordered the amp on Wednesday, it was delivered on Thursday, and its now all set up on Friday morning. All we have done so far is use the setup wizard but already it sounds a vast improvement over our previous ( and admittedly elderly ) Yamaha. I am sure that there are many tweakes yet we can make, but "out of the box" it is worth every penny. As ever, great advice and pricing from the guys at Cheltenham.

Rated 5 out of 5 by from Great Product, great Service Set it up yesterday, on screen instructions very easy to follow, however if you have rear wall speakers use the surround speaker setting (diagram shows them on the side), otherwise it does not recognise it. Really impressed with the sound and vision. Been using a Tag McLaren AV32R with a separate amp for years. With the AVC-X3700H this is all integrated. I never thought the AV32R could be replaced. Just brilliant. Not to forget my friendly local Richer Sound staff, Watford) in particular Heather. Many thanks. Now to telephone her and order the ceiling speakers.

Rated 5 out of 5 by from Excellent piece of kit, easy to install and set up Purchased this to replace previous one which had broken down. Very quick and easy to attach to existing inputs and outputs and speaker system. Excellent setup assistant built in to get the basics and simple to tweak to your own custom setup. Great sound and video reproduction and very easy to use. Use this for various inputs with ample room for more and outputs to TV and projector. This unit copes with everything I need in audio and video and for household use I don’t think you old need anything more.
