Stream music from your iPad, iPhone, or computer running iTunes with the AVR-X4000's built-in AirPlay support.

Stream easy with AirPlay

Whether you've got music stored on your iPhone®, iPad®, or computer running iTunes®, AirPlay makes it as simple as pressing “Play” to stream songs to the 'X4000. It's so easy to browse and listen, you may find yourself rediscovering music you forgot you owned. Even if you don't have hundreds of gigabytes of digital tunes, don't feel left out — the 'X4000 features built-in support for Spotify® and SiriusXM subscribers, as well as free Pandora® Internet radio and DLNA-compatibility for networked PCs. That's millions of songs at your fingertips before you've connected a single component to this receiver. AirPlay requires a wireless home network and a wired connection between the receiver and network.

Wide-ranging multi-zone, multichannel flexibility

Denon AVR-X4000 7.2-channel home theater receiver with Apple AirPlay

The AVR-X4000 offers lots of connection options, including 11 pairs of speaker outputs.

With an impressive 11 pairs of speaker outputs, the AVR-X4000 offers maximum setup flexibility, so you can customize your home theater to your own space and needs. You can connect and control audio and video components in up to three rooms. Connecting a 5.1 surround system in one room leaves outputs for a stereo system in a second room or third room — no additional amp required. Plus, the additional HDMI outputs means you can connect an HDTV and a projector in one room as well as another TV in a second room. Not interested in a multi-zone system? Then use those extra channels in Zone 1 for "front high", "front wide," or "surround back" speakers to give movie soundtracks even more depth and realism. Or try bi-amping your compatible front speakers to squeeze even more detail out of your two-channel music. By adding an additional stereo power amplifier, you can expand your options even further.

Customized setup with Audyssey

Denon's home theater receivers continue to get easier to set up and control. One of the ‘X4000's best setup features is the built-in Audyssey speaker calibration software. Not only does it optimize your system to fit your room, but it can also tone down loud commercials, improve dialogue and surround effects during low-level listening, and even reduce the amount of bass you can hear in the next room. The ‘X4000's full-color on-screen display uses lots of graphics makes these and other settings a breeze to navigate. Once you're set up, be sure to download the free Denon Remote app for your Apple or Android™ smartphone. It's the simplest and most intuitive way to control your receiver via your home Wi-Fi network.

High-res audio

Enhanced audio performance

If you're serious about your music, check out some of the audio features Denon included in the AVR-X4000. Hybrid PLL circuitry reduces timing errors — known as "jitter" — that occur with digitally connected components like Blu-ray players and hinder clear, accurate playback. You can even go a step further with Denon Link HD, a separate connection between the 'X4000 and a compatible Denon Blu-ray player. This connection separates the disc's timing data entirely from the HDMI audio stream, allowing the receiver to accurately re-clock the data for even more sonic accuracy. If you have a USB thumb drive with high-resolution files, pop it in the front-panel USB port and let the 'X4000's high-performance 192kHz/24-bit digital-to-analog converters translate them into rich, detailed music. Even MP3s and other compressed digital music formats can sound great thanks to Denon's Compressed Audio Restorer.

The free Denon Remote app for Apple and Android lets you easily control the 'X4000 from your smartphone.

Audio, video, analog, digital...bring 'em on

With its abundance of inputs, the 'X4000 can handle just about any component you can throw at it. Seven HDMI inputs offers plenty of room for Blu-ray players, gaming consoles, cable boxes, and more. Analog-to-HDMI upscaling means you'll only need a single cable to connect this receiver to your HDTV. Add a second subwoofer for room-shaking movie effects. Connect your turntable and enjoy the warmth of vinyl. Or embrace the digital age with the front-panel USB connection for your iPod® or other Apple device. It creates a direct digital connection, so you can get even better sound from it using the 'X4000's circuitry. Throw in lots of digital and analog audio inputs and this receiver is prepared to take on almost any home theater setup, no matter how extensive.

    Fails just out of warranty - again!

    Scott from Louisville, CO on 3/20/2017

    Crutchfield Customer Review (What's this?)

    Receiver features are nice, unit is generally okay except for parts that start failing over time. Biggest issue is that the main power button has totally failed a couple months after the warranty expired. I'm sick of this design to fail process used by Denon and others - vote with your wallet and don't support these products with forced upgrades through failure. Even if Denon would supply a free part, which they are Not, the labor cost alone would be about 1/3 the cost of the receiver to fix. Oh, did I mention shipping it for a repair to a service center and the new damage that round trip shipping could induce??? ARGH!!! Thx for nothing Denon!! (Note - review is just a personal opinion, not a statement of fact about planned part failure.)

    Pros: Nice unit when it works

    Cons: Planned part failure - design in a weak part on something used frequently (power switch). The planned design is just my opinion but has happened before and to others so it doesn't seem like a coincidence any more.

    Overheat and shutdown problem started around 18 months

    Craig from Vancouver, WA on 3/16/2017

    Nice receiver overall but i have been having the overheat and shutdown problem that others have been seeing. ours started doing it about 18 months into service and has been getting more and more frequent to where it is now unusable. For the last month we have had a fan sitting on the top blowing air into the cabinet just so we can use it. pretty pathetic that this is such a widespread problem and Denon has not addressed. The warranty will soon be expired and i have not doubt that the overheating and shutdown will continue and the receiver will soon become worthless. when this was purchased i did not consider it to be a 3 year consumable but that is how it will probably work out.

    Pros: nice configuration options sturdy connections decent smartphone app

    Cons: poor quality poor investment if it only lasts a couple of years

    So far so good, sounds and preforms great!



    Excellent device until I started having issues

    Joe from Kentucky on 9/20/2016

    Crutchfield Customer Review (What's this?)

    When I first bought this device, I loved all of the capabilities and definitely enjoyed the great sounds that it produced. One main reason to buy this one is Audyssey MultEQ XT32. Also, this receiver gave me all the connectivity I wanted and more. I connected a nice set of 7.1 Klipsch speakers. I have my movie room all calibrated with sound panels all around to remove sound reflections. It was excellent until the receiver started to go into protection mode while it is switched off.

    Pros: 1) Audyssey MultEQ XT32 2) Great connectivity 3) Great sounds 4) Excellent capabilities

    Cons: By far, one of the worst tech support I've experienced. Did Not meet my expectation at all. Although my receiver is under warranty, Denon tech support has no clue how to support a device at this price. I'm an engineer and work in a technology company, but we do take care of our customers. My receiver started to go into "protection mode", and Denon suggestion is for me to take months in trying to identify the reason. I had great experience with Onkyo before, I may needed to stay with that.

    good product, if it lasts

    steve from fairfield, OH on 2/8/2016

    Crutchfield Customer Review (What's this?)

    my 5th Denon, replacing a 3311, youngest of my amps, all others 4311 and 4800 still work great, had to do major repair on 3311 to get back from red flashing power light of death (needed to re solder the power transistor board, all working fine for past week , net don't need this 4000 as a replacement but will keep as a backup and likely use in another area.... did power up and set up during 3311 repairs, 4000 worked very nice and was mostly a familiar interface, same remote, etc. will update if problems, don't expect any

    Pros: mostly same as other amps easy to set up works fine so far great scratch and dent value

    Cons: none per se, just a bit nervous about lasting based on 3311 and many internet posts of red death failures for Denon (and many others) amps

    Fantastic upgrade!

    Zach1cora from atlanta, GA on 2/1/2016

    Crutchfield Customer Review (What's this?)

    I was on the fence about my receiver. I spent a lot of time on YouTube and other sites. This X4000 is incredble! Easy to setup and I am hearing things that I never heard before. The picture improved also on a Samsung 8000 Plasma and I did not think that was possible. Buy it and stretch your TV needs a few more years!

    Pros: All

    Cons: None

    expecting a working consistant product

    Mr. Rogers from Maryland on 1/10/2016

    Crutchfield Customer Review (What's this?)

    Since I have had this receiver for less than a year, it has been replaced, and now it must be replaced again but now must be shipped back to the Manufacture. It is now overheating and will cut off within one minute. Great receiver but it seems to have many issues that has made such a great receiver not enjoyable. I am looking for my 3rd receiver under warranty.

    Pros: there is a new model


    Denon AVR-X4000 In- Command

    FrankF from Pennsylvania on 8/5/2015

    Crutchfield Customer Review (What's this?)

    Easy to set-up. A nice upgrade to my Denon 5600 of 15 years ago. Now I have all the audio upgrades needed for all of todays blue-ray discs and hi-def and 4k upscaling. I am hoping that the quality of the AVR-X4000 gives me uninterrupted enjoyment as my 5600 did. If still available, I give it a thumbs-up



    Denon AVR-X4000

    JS from Iowa on 7/17/2015

    Crutchfield Customer Review (What's this?)

    Receiver only played one speaker in Zone 2. Crutchfield technical support suggested my wiring may not be correct. I had local AV contractor check things out. They came to the same conclusion that there was a probelm with the receiver. Sent the unit for repair under warranty. It has been 15 days since they received it and they are still waiting on parts. At this point, I can't say too much good about Denon or Crutchfield.

    Pros: Hopefully I will be able to offer a more favorable review once I get the unit back.

    Cons: Defective unit.

    Excellent AV Receiver

    AJD from Jacksonville, FL on 7/12/2015

    Crutchfield Customer Review (What's this?)

    Even though I still have an excellent older Denon AV receiver, I decided to update it with this newer one. So far, I'm very impressed with the HD tuner, the array of audio and video inputs, the great selection of online audio available, and the audio section is Denon excellent. Plus, the buying process and customer service and support from Crutchfield is the best! Thank you!

    Pros: Excellent quality, bright display, great functionality, HD tuner.

    Cons: None so far!

    Denon AVR-X4000

    LoganM from Utah on 6/26/2015

    Crutchfield Customer Review (What's this?)

    It worked great and sounded great for the first week, then it stopped getting any signal from the HDMI inputs. So I had to return it. Crutchfield has been awesome and sent me a new one. Their support team was very helpful and I plan in the future whenever possible to use Crutchfield. I had to knock off one star for it having problmes, but would happily change it to 5 if I don't have any problems with my new AVR-X4000.

    Pros: 1. Sound is awesome! 2. I could backup my settings to my computer so I didn't have to rerun the audyssey setup again. (Having twin 2 year olds it is hard to get the house quite) 3. Easy to setup guide 4. Love how configurable it is 5. Great price 6. Customer Service and Support 7. Tons of inputs

    Cons: Just that it stopped working after a week, I am really hope my new one lasts!

    Easy setup, splendid sound

    Scotty from Scottsville, KY on 6/17/2015

    Crutchfield Customer Review (What's this?)

    I followed the simple, onscreen instructions and ended up with a quick, flawless installation, including connections to a windows computer, a Blu-ray player, a cable box and the internet. The sound from everything is clear, detailed and realistic. Previously muddy, often unintelligible dialog is now crisp and easily understandable, both from my cable connection and from the Blu-ray player. I could not be happier!



    Denon X4000

    Justin from California on 5/17/2015

    Crutchfield Customer Review (What's this?)

    Good features, but runs extremely hot. My understanding the video processor generates significant heat and that can't be turned off even if you don't plan on using any of the upscaling features. Audyssey XT32 is great and the sound quality is decent.

    Pros: Great features, really good value on closeout

    Cons: Runs very Hot

    Denon AVR-X4000 is sweeeet!

    postal from New England on 5/14/2015

    Crutchfield Customer Review (What's this?)

    Setting up the receiver for initial viewing was easy. The on screen capability had me selecting speakers and tweaking sound immediately. It was akin to my old Onkyo (HDMI panel death as so many others have had) so i had some base familiarity going in. I did have to read through the manual to get my main Polks set up for bi-amp mode. That took a bit getting through the massive manual on my phone (wife has since printed manual out at work... sweet!). But once things were in place, running the polks, PSBs, and Klipsch sub were fantastic. While not as loud as the Onkyo, I have noticed several things in movies i have previously never heard so I believe the processing and delivery to the speakers has been raised for me. Setting up the internet was a breeze as well. And go to Google Play to get a better controller for your phone. It will make a big difference. My wife is a big Pandora fan while I am stuck using my CDs. Just a preference. Music sounds great pushed through two channels. All in all, it has been about a month with this unit and i am pleased. It I love the fold down panel in front. Hides a lot of stuff. Thanks Denon and Crutchfield!

    Pros: Ease of set up Sound processing quality, especially in video

    Cons: No paper manual (though I understand why they don't) Will take time (like any new toy) figuring out EXACTLY how I want each mode to sound

    Meets expectations and exceeds them as well!

    JeremyR from North Carolina on 5/6/2015

    Crutchfield Customer Review (What's this?)

    This receiver is feature packed and really surpasses my needs. I bought the receiver mainly for the 9 band EQ. I really dont even use it though because audyssey auto calibration was excellent. I'm upgrading from a sony str-dh540. The bass extension I get from my subwoofers is alot better. I can honestly say that my subs used to roll off around 29 hz, and now they go down to about 22hz. Im a car audio fanatic and I love lows so that really made me happy. Also I can control the receiver through my phone with the denon app or i can use Air Play with my phone and control the volume directly from the volume buttons on the iPhone. I will be satisfied with this until they make a newer higher quality sound format. I also saw that someone said the unit gets hot after extended use, well, with any amp when you are nearing its limits, its efficiency is going to drop, resulting in excess heat. Do not be fooled, the receiver does not heat up much at all unless you are at its limits for a long period of time.

    Pros: Sound Quality is A1 The receivers looks A1 Pre-Outs can correlate to an 11.2 system

    Cons: Receiver is a little difficult to operate for the first few days.

    Not sure yet

    Rich from Florida on 4/9/2015

    Crutchfield Customer Review (What's this?)

    The top of the unit gets very hot after extended periods of time. I turn it on around 6am and I don't turn it off until ~9pm. Problem: I noticed that if I apply pressure to the top of the cover, when it's hot, the unit powers down. Also, I had an initial problem during setup, the unit froze in the internet radio mode, then it cleared up by itself, no problem since.

    Pros: Great unit, lots of ways to play different media. Works well with the iPad and iPhone app; wish there is one for my iMac.

    Cons: Setup was difficult, owner's manual needs more description for functions

    Good Value in a Denon Receiver

    Rudeney from Alabama on 3/30/2015

    Crutchfield Customer Review (What's this?)

    This replaced my aging Denon AVR-3803, driving my main living room 5.1 HT system with UHD TV, plus a 2nd zone on a covered patio. I upgraded the patio TV from a CRT to HD, so the 4000's 2-zone HDMI was a perfect fit. I am very experienced with AV setup, so setup was quick and easy. I use custom touch-screen remotes so I have no opinions on the stock remote. I am very satisfied with the AVR-X4000 and really have no complaints, just a "wish list" of features I'd like to have. The Good: Familiar connections, plenty of input configurations, on-screen display, guided setup menus, great surround sound, flexible setup screens to tweak everything imaginable, 2nd zone HDMI out, "ARC" for TV audio via single HDMI cable, feels solid, sounds solid, looks nice, reasonable size, a good value for price/features, Insta-Preview "PIP" function, HD radio tuner. The Wish List: OSD and up-conversion of non-HDMI sources for the 2nd zone, faster iPod and SiriusXM app response, a rear USB in addition to the one on the front panel, ability to superimpose OSD without additional video signal processing (could be an issue for picky user and/or copy-protected HDMI 4K video). Overall, I am satisfied with this receiver and would recommend it. Maybe in another 10 years when I get ready to upgrade, Denon will address my minor complaints.

    Pros: Price, flexible connections, 3-zone output, quality, features

    Cons: On-screen display requires processing of video signals, lacks flexibility with 2nd zone video, slow "apps"

    Definitely a sweet reciever

    Great reciever



    Plug, Follow onscreen instructions, and Play.

    iNoteboom from Oviedo, Florida on 3/14/2015

    Crutchfield Customer Review (What's this?)

    The Denon AVR-X4000 is perfect for my 5.1 surround sound living room + 2 stereo speaker pool patio setup. This amp powers the surround sound of movies and satellite through out the 500 sqft space with power to spare. Perfect for engaging casual family movie watching. I actually enjoyed the setup. It was completely onscreen driven with instant feedback, and it beautifully tuned the system for the space. I suspect that there are many receivers that could claim this, but what really sold me on this receiver was the ability for the AVR-X4000 to play digital sources through a powered Zone 2. This is key, for I only use digital sources: Satellite, AppleTV, BlueRay player, iTunes, Pandora, and SiriusXM. The fact that I can take any source and play it our on the pool deck, regardless of what is or is not playing in the living room is key. The final test was past with the fact that everyone is able to use the system, without me getting a support call on my cell phone ... Everyone: my young children, my wife, the babysitters .... my parents and in-laws. I am sure there are more features that I shall get to at some point, but it'sworthy to note that you needn't know all of them to operate the Denon. We were enjoying helicopters and explosions, within an hour of opening the box. Happiness all around.

    Pros: Plug, follow onscreen instructions, and play. Powered Zone 2 from Digital Sources Everyone can use the system.

    Cons: No WiFi capabilities Can't read the remote without reading glasses - my problem, maybe not yours :o)

    Crutchfield Customer Review (What's this?)

    This receiver is incredibly advanced compared to the unit it replaces, network connectivity, HDMI pass thru, HD Radio, Android app capabilities. I am very pleased with this unit.

    Pros: Too many to list.

    Cons: Gonna take a while to learn about all the capabilities.

    Great Receiver!

    Always DENON

    Steve M from Texas on 2/28/2015

    Crutchfield Customer Review (What's this?)

    Bought this to replace my 3808CI which after 6 years had given up the right surround channel. Ordered from Crutchfield and it was here asap, considering the winter storm we have been dealing with. Double boxed and packed nicely. This unit is basically a lateral move for me, but it does have some more HDMI inputs and the XT32 with dual sub control. That was what I was looking for and this does not disappoint!!! I like DENON products and feel that they are priced very competitively in the market. So far no problems. Just takes a bit of getting used to the menu system. I love the way the inputs can be reassigned and renamed on the fly. The power is not an issue for me really as I drive the front mains with an Emotiva amp that does 500wpc into 4 ohms, and drives my Magnepan 1.7's beautifully and lets the stress of driving a 4 ohm load be carried elsewhere. Good Job DENON and Crutchfield for doing internet sales right!!

    Pros: VERY FLEXIBLE and GOOD BUILD QUALITY at this price point.

    Cons: 2 channel stereo settings are available only when certain speaker configurations are selected, which will preclude my using the assignable amps to drive my zone 2 speakers.

    This reciever is fantastic! It has replaced a Denon AVR-2805 which I loved. It is every bit it's equal with the benefits of HDMI. The old receiver and the new receiver are driving a 7.1 system. The channel separation is more clearly defined on the X4000 along with the sense of clarity. Setup was very simple. The only reason for 4 stars is the lack of a printed manual, just a CD, a little awkward while learning the features. I prefer written for quick reference. Of course, that is what we get today. I have no problem recommending this receiver.

    Pros: The amount of input sources, good dynamic headroom, 4k up scaling and usual Denon build quality.

    Cons: Lack of printed owners manual and only two optical inputs. Cannot input SACD from my Denon SACD player, it has no 5.1 preamp input though it does have 7.1 preamp outputs.

    It's not me that's's you, Denon X4000. We have to break u

    Crutchfield Customer Review (What's this?)

    I spent a frustrating month trying to get this unit to work. The bottom line is that it couldn't handle a 7.1 load along with Zones 2 & 3. I tried two different units and they both failed. The protection circuit would kick in and shut off the unit. Extremely frustrating when watching a movie or hosting a party. I liked that it was IPhone compatible, but the unit doesn't have built in wifi- showing that it is the direct descendant of a dinosaur. The power going to zones 2 and 3 was not enough to make a 110 watt amplified signal sound good. I figured since the price has come down so much- this must be a good opportunity to get a really high end unit. That was not the case.

    Pros: It had volume control for zones 2 and 3 Crutchfield will allow you to return the unit

    Cons: Went into protection mode, not enough power for multiple zones, no wifi, not user friendly. I wouldn't recommend this unit if you are powering more than 2 speakers. Denon used to make great stuff, but is not going to make it if they don't keep up with Sony.

    Very good HT receiver

    TV Tom from Indianapolis, IN on 2/2/2015

    Crutchfield Customer Review (What's this?)

    Very cost-effective Home Theater receiver with lots of inputs and outputs of many different varieties. Easy to set up, lots of control capabilities. Sounds excellent. Can send sound to 2 rooms, or even 3 in some configurations. Automatic EQ and room setup with included mic.

    Pros: Really appreciated the inclusion of HD Radio in the unit. Can use its Web page and/or the on-screen to configure. DNLA means that I can input a media server. Starting to play with Internet Radio streams. AirPlay means I can stream from my iPod. Audyssey made fast work of room EQ and timing adjustments.

    Cons: You can only select 4 favorite stations, across all of the possible inputs. Would far prefer 4 favorite FM stations, 4 favorite Internet Radio stations, 4 favorite Pandora stations, etc. Wired Ethernet only, you have to add an outboard Wi-Fi adaptor.

    Great Reciever

    Joe C from Saratoga Springs, New York on 1/31/2015

    Crutchfield Customer Review (What's this?)

    Every conceivable must have option, world class Denon amp and more inputs than you'll ever need. Absolutely untouchable at $800 and puts any Onkyo, Sony, Yamaha or Pioneer at twice the price to shame.

    Pros: Starts with the Denon amp. I buy for music first and take whatever comes along for movies. You will not find a better sounding receiver unless you spend 3x as much and most of those super high end systems lack true DSD SACD playback.

    Cons: Some people might complain about the lack of bluetooth but I could not care less. I don't listen to compressed music from any device or in any format.

    This piece by Denon,is connected to a pair of focus Legacy speakers in my home.The sound from this union is the sweetest I have ever heard. The highs are tight and crisp, the bass is thunderous.

    This was my first experience with Crutchfield. I'd heard great things, but boy-oh-boy will I not be deviating from this company for my electronic needs. The finest internet purchasing experience one could hope for. 60-day return policy with nearly no questions asked. Free two-day shipping to Georgia. (It got here in one. I have no idea how seeing as how I ordered it at 6pm and I got an email saying it shipped at 7pm). Are you kidding? It was here in less than 36 hours.... For free. The icing came a few days ago when Crutchfield MAILED me a hand-written thank you note. Crutchfield you have my business for life. Oh- and this Denon replaced my Yamaha Aventage RX-740. At $800 they're giving it away. What a steal for the Audyssey and sub EQ. Has my Rythmik LV12R's tightly humming and kicking when needed. It's night and day from the Yamaha. Long live Crutchfield!!

    Pros: Audyssey sub EQ Unit not as big as the sound it produces

    Cons: I haven't found one after a month.

    Denon AVR-X4000

    Joe from Staten Island, NY on 1/24/2015

    Crutchfield Customer Review (What's this?)

    This receiver replaced my Onkyo TRN 838 that served me well for the last 2 years. I basically wanted to try something new and decided to give this Denon try. The Audyssey room correction is the same as my last receiver, so I was very familiar on setting up my equipment and calibrating it. So that went fairly well and quickly. Sound quality in my opinion is VERY GOOD. Very laid back and smooth. The Onkyo was a little more in your face and "bright" if you will. BUT I still like the Onkyo sound. The Denon is better for my music tastes: mostly Jazz, Latin Jazz, and Acoustic music. The Denon allowed me to play my music loud, without any distortion, and sounded fantastic at all levels. So I cannot comment on the video processing capabilities of this unit. Networking function, on screen displays, internet radio, connecting to my network were all on-par with what I am used to. It all worked, and worked well. No surprises here. Pandora out to my patio is what I use most in that zone, and it sounds great. For the record, I am using this receiver solely as a processor. It is connected to my Outlaw Audio Model 7500 amp which feeds ~300 watts to my Emotiva speakers at 4 ohms. The denon onlys uses its amp to power my outdoor speakers. No problem there. I have all video processing turned off and let my sources and display handle the video side of things. Denon app for phone/tablet works great once you get used to it. Onkyo app was a bit better-but only for aesthetic reasons.

    Pros: Sound Quality, networking functions/apps, easy learning curve for those with some experience in home theater. Free app and IP control of unit via a web browser. MANY features like EQ, room correction, video processing, etc. to keep one tweaking for months.

    Cons: Remote could be better-no back-lighting although one would think so from looking at the buttons.

    Pros: Power! Audyssey "platinum". BiAmp capability. Last years' model - Best price that I could find from a reputable dealer!

    It takes more than $3000+ to approach the level of audio performance from other brands out there. This is also a feature-packed device with 3D, 4K, Apple AirPlay, etc. Denon is really the only mass market receiver to consider if you want to hear and see your content natively. In other words, for the money, you get what is on the disc without "flavor" added.

    Pros: Performance-to-the-dollar

    Cons: None

    Crutchfield Customer Review (What's this?)

    Initially, I had trouble connecting this unit to my wired home network. Although this receiver had a DHCP -assigned address on my local network, it would not work to access the Internet despite several network and receiver power cycles. The receiver kept saying there was no Internet connection. I finally solved this problem by performing a complete receiver reset procedure: while pressing the Info and Back front panel buttons simultaneously, I power cycled the receiver. As soon as I performed this factory reset procedure, all was well. The X4000 now was able to access my local wired network and also access the Internet. To get the Internet access working, I did not do anything to my cable modem or the wired/wireless router that was connected to the X4000 with an RJ45 cable, although I had previously performed many troubleshooting procedures/resets on these units before I did the factory reset on the Denon receiver. I really like the sound quality and various features of this Denon receiver with my home theater system. The access to Pandora and the Internet Radio features are really excellent and easy to use. I am hoping that some additional HD Radio The sound of this receiver is excellent and is a little "warmer" than the Onkyo TX-NR717 receiver that it replaced. I have not yet used the advanced Audessey speaker optimization feature, as I want to make certain that this receiver works well for a week or two prior to spending more time on a more advanced configurati

    Pros: Great power and feature set. Fairly compact for its power rating. Nice appearance and user interface.

    Cons: Did not work out of the box to access the Internet. Had to perform a complete factory reset to gain access to the Internet.

    This product is excellent! It has some really great features (Main Zone HDMI video output from one source, such as a cable box, while using another source for audio, such as Internet radio) and was very easy to set up (great step-by-step guide). The speaker connections can be a little frustrating; I read a similar review and highly recommend ordering some banana plugs.

    Pros: Great features for the price Easy to set up (including network connectivity)

    Cons: Speaker terminals are a bit tedious

    Nice overall AV receiver. I purchased it to run a home theater setup AND push sound and HDMI signal to a nearby patio. It has plenty of power to push the theater speakers and then some. The two Definitive AW6500s on the patio will turn the neighborhood into a block party if I turn it up loud enough. Oh, and the iPhone app works GREAT. It's nice to control all functions of the amp from an app on your phone.

    I got this receiver do replace my Deonon AVR 1913 as I was running into a few limitations when it came to multi zone/room playback. Also, Now I'm able to output digital signals (like apple tv) through my second zone speakers! (A frustrating limitation to the prevous generation models) Also, it has multiple hdmi outputs so I can either mirror OR broadcast a different source to a secondary theater room. A few other things that make this a great upgrade -I'm now able to adjust the speaker output for my second zone so it sounds much better than it did prevously -When listening to an audio source in your primary zone, you can set a different video source so for instance you can watch tv or play video games while listening to music.

    Pros: Easy setup, Great audio calibration for effortless awesome sound, multi-zone features, multiple hdmi outputs, great sale price savings too!

    Cons: none.

    Don't buy this receiver

    Mark W from Orange CA on 9/28/2014

    This receiver shuts itself off intermittently, goes into protect mode. My second trip to authorized repair ended when, without any notice, a box was delivered to my door with fedex asking for my signature. When I opened the box I found a refurbished unit. the authorized repair people must have contacted Denon and they just sent the refurbished unit without any communication with me. I haven't tried the refurb yet but from what I read an awful lot of people have had the protect mode problem. apparently there is no fix. Beware, others write their review in the 1st few days of use, so they don't know the problem will occur with time.

    Pros: when it doesn't work how do you write pros?

    Cons: horrible rate of failures should be pulled off the market

    Great until it is not

    Victor from Inland Empire, California on 9/26/2014

    I purchased this unit in March and it does what it advertises until it doesn't. The unit started to go into protection mode and shutting down in late July. It would work sometimes, but then it started going into protect mode after just a few minutes of operations. I worked with customer support and they said I needed to take it into their repair facility (an hour drive from my house). The technician that worked on it said it was common in these units and he had to replace 4 transistors and add some ground cable. Denon offers free shipping back to the customer, but I had to pay $15 to have them box it up for me. I should get it back today. As I said, when it works it is a great unit. I just hope this is the last of my problems.

    Pros: Lots of extras, Love the Audissey and Airplay. Plenty of power.

    Cons: Died in six months requiring repair.

    I purchased this to replace an Onkyo receiver. This a great receiver! I am using it in a 7.1 system, but can expand it to 9.2. I use the both powered zones, no need for an additional amplifier. I had one on hand from the old unit. I use it for my Zone 3 for the deck. Now I have 7.1 in main zone and full power for my zone 3 and it sounds great . I wish I had purchased the Denon first. I liked it so much I purchased an scratch and dent Denon AVR for my basement movie theater. The install and set up was very easy with the on-screen menu, and the Audyssey mic to fine tune the system. This is a great receiver that is very easy to do firmware updates. Buy this receiver you won't go wrong.

    Pros: Easy set up, simple to understand on-screen menu, Great sound!!

    Cons: None!

    Crutchfield Customer Review (What's this?)

    A fabulous amplifier! Using Banana plugs is the way to go with this one. Using all of the speaker connections, including front height and width, and back surround. With my Polk speakers it is as good as the movie theater. The Audessey set up and the on screen help by Denon made the sound magical and completely fill the room with great frequency balance and accuracy. I have watched movies that I have already seen just to be immersed in the sound track that I was missing before. 7.1 surround is absolutely amazing. I have had no problems with the power requirements of my speaker set-up. A smashing success!!

    Pros: Powerful Balanced, accurate sound Easy set-up Great controller Nice to know Crutchfield is there if I ever need them Worth the money

    Crutchfield Customer Review (What's this?)

    Upgraded 8 year old Marantz SR8400 7.1 110W receiver that was pre-HDMI, and pre wi-fi. Audio playback was excellent but notably, movies soft spoken dialogue was lost despite re-balancing efforts. I aimed at an Audyssey licensed product with Sub bass EQ XT option, not just Multi EQ XT. Crutchfield was wonderful, answered their phone on Sunday, were polite when I wanted to change my online order (I'm a wishy-washy) and they delivered this Denon AVR-X4000, an open box special, at a competitive price. I couldn't tell why this was labelled open box. I printed out hard copy of the Denon User Manual off Denon website to have handy, and stripped out my Marantz. I followed the setup guide exactly. I HAD NO PROBLEMS. My first Audyssey set up was a fail. Redo worked. Audyssey helped me find reversed polarity center channel, and my cross labelled Surr Rear and Surr Side (Doh!). I ended up preferring direct tweaking with the Audyssey equalizer. I am happy - movie dialogue is noticeably better, and my sub-woofer is reborn!! It BOOMS!! So far my wi-fi and internet features are running through my wi-fi Blu-ray, and I haven't tasked the Denon with it yet, and I just downloaded the i-phone app and haven't tried it yet. i-phone direct hook up plays fine w/ on screen art. HD radio plays fine but it's not my thing. SACD audio 2 channel playback is great, but I "think" I preferred my Marantz sound? But like I said, movies are WAY better, and that's primary use nowadays!

    Pros: Up to date features and connectivity. Audyssey set-up made a difference and IMHO puts this product above competitors products at this price point.

    Cons: Um, none. You do need to have a little geek in you to set up ANY AVR receiver, but this one was easy enough.

Each provider blamed the other, but no one asked if there was more than one network. Miss having a n outlet on the rear panel.

    Swiss Army Knife of AV Receivers

    Jason Y. from Burbank, CA on 2/9/2014

    Crutchfield Customer Review (What's this?)

    This is a replacement for a Denon AVR-2310CI. The 2310CI is very complicated and has an excessive amount of remote control buttons and functions in comparison to the X4000. The X4000 on the other hand is very evolved from the predecessor 2310CI. The X4000 has improved and refined A/V processing power, and presents its features in an easy to use straightforward manner. The X4000 is what I imagined a 21st century receiver to be. There is a comprehensive list of subscriber based and free internet radio, including local over the air AM/FM HD radio capability. The X4000 will also playback music files on my NAS drive hosting DLNA file services. All of these functions just worked like an appliance, nearly plug and play (no fiddling around with complicated network settings that are often time consuming to set up). I was amazed at how far I got without the instruction manual. The X4000 has great sound and a much improved Audyssey processor from earlier generations. The X4000 feeds a Paradigm Studio 100 speaker system. The receiver is more than capable of driving these speakers with plenty of bass with clear mids and smooth highs. A few buyers may need 4 ohm capability and more power, though for most home theater and hi-fi systems, this receiver will exceed expectations.

    Pros: Lots of great features, easy to set up. Excellent cost/value to feature set ratio. Video processing is on par with great audio performance. This is a great AVR. If you're on the fence about this purchase, just buy it, you won't regret the purchase.

    Cons: No printed instruction manual; you'll have to read the manual on your computer or PDA. The next task for improvement should be in developing a much better I-Pad/PDA remote control app for these AVR receivers. The latest generation of apps are an improvement from past versions, though they still have a way to go. I would be OK with paying for a really great app to control and set the X4000. No 4 ohm output; you'll have to buy Denon's top of the line receiver to get this capability.

    I am not disappointed

    I purchased this Denon X-4000 a couple of weeks ago. I am very happy with this purchase. What a difference the Audyssey MultiEQ XT32 makes. The sounds from blu-ray moves and PS3 games is astounding. I was using a cheap Sony AVR and everything sounded very dull and not appealing. Since I did the Audyssey, I have found new likeness for my movies and games. I watched the Superbowl using this receiver and it was a great sounding experience. I would highly recommend this receiver.

    Pros: Great Sound, looks good and was very easy setup.

    Cons: None


    AV enthusiast from Doylestown, PA on 1/17/2014

    Crutchfield Customer Review (What's this?)

    I wanted to like this unit but it failed short , the second zone hdmi out did not work as I expected it, but that's just one of the hdmi standard limitations, so I can not blame denon for it, I had to use an hdmi repeater for the hdmi 2 out, also if I want to use the second or third zone for audio I would have to set the main zone for 5.1 and loose two speakers as I have 7 speakers in wall and in ceiling installed, I have invested "enough" money on it so I am not just going to have two speakers not doing anything, my old receiver would handle this just fine as the same built in amplifier shares SBSs and zone two speakers, I'm limited to 5.1 when using zone 2 but it's done with one simple click and not through the menu. So with regret I have to send it back, as I have to de install and re install all this equipment, Crutchfield support was very good, I called tech support twice...

    Pros: Sounds good, the app for the iPhone and iPad works very well, you're capable of switching inputs, adjust the volume, etc

    Cons: Second and third zone have too many limitations, and this was the reason why I got this unit

    Great so far

    Jeff T from Richmond, VA on 1/8/2014

    Crutchfield Customer Review (What's this?)

    This replaced a Denon 3808ci. The main feature I was looking for was digital out for Zone 2. That function works well, however only if the original content is in 2-channel format. The Audyssey32 room correction is noticeably better and eight mic placements are allowed for the calculation. The GUI is much more intuitive and user friendly. Unlike other reviews I have seen, it does run any hotter than my old receiver. The ARC configuration is a little cryptic. I have decided not to use it, but did work with my Panny VT60. Bottom line is that sound is great, the room correction is really impressive and the sound stage seems more cohesive and integrated than the older model. I would recommend it.

    Pros: Great room correction, more intuitive than older Denons, digital out Zone 2.

    Cons: Flaky ARC

    Great AVR

    HowieR from Fort Lee, NJ on 12/31/2013

    Crutchfield Customer Review (What's this?)

    Purchased one week ago as a replacement for an aged Onkyo in the family room. Right out of the box no problems. Fits perfectly in the console. AVR connection guide steps anyone through the speakers and input device connections. Plenty of HDMI inputs and outputs. Currently running a 7.2 configuration. Not yet taking advantage of multi zones but noted comments from other owners reviews. Using the Audyssey XT setup and microphone worked pretty well, however I did need go thru manual setup and tweak some of the speaker settings - subs and main speakers. Needed to make a fine adjustment to the xover frequencies for the floor standing speaker sound to open up more. Media server works great with streaming devices and controlling them from the remote straight forward. Found STB audio pass through a little quirky until setting change as well as power up was going into TV mode and not SAT/CBL. Using with B & W CM series floor standing speakers & Center, 2 subs that go down to 17hz and Klipsch ref series surround speakers mounted on the walls.

    Pros: Sounds great so far. A lot of musicality, not just oriented to theater sound reproduction as I have heard from others.

    Crutchfield Customer Review (What's this?)

    First unit arrived promptly but proved to be defective. Crutchfield offered replacement without any hassle, but delivery of this unit has been ponderously slow via UPS so I'm still waiting.

    Pros: Sounded good prior to repetitive shutdowns. Initial set up went smoothly.

    Cons: Play... shutdown. Play.....shutdown. Play.....shutdown. Ultimately it would shutdown with nothing connected. Web survey now suggests that others have experienced similar problems with the X4000. I hope the replacement works as advertised if and when it is delivered.

    Disappointed - too late to return it though

    Crutchfield Customer Review (What's this?)

    I bought this unit in July and in October the unit shut down while using it and would not power up again. It went continually into protect mode. After working with Denon tech support (this happened just after Crutchfield's 2-month return policy) and was told I had to bring the receiver to a local Denon repair shop to get it repaired. A three-month old receiver! The authorized repair shop fixed a bad solder joint on internal connector CN203. I was told this was a factory defect (my receipt for the repair had Factory Mod. DZ10-171 on it for those who want more details). I asked the repair shop if there was anything in my home theater setup that could have caused/exacerbated this problem and he said no, it was just a factory defect. Beside that, I find the power of this unit to be weak. I replaced a Yamaha RX-2600 receiver with this unit and the power is NOTICEABLY less. I use all three zones of this unit and there is also an audio delay between the main zone and zone 3 if you and using the same source in both zones simultaneously. Both Crutchfield and Denon tech support could not find a solution for this issue. I stumbled upon a fix for me, which was there is not and audio delay between the main zone and zone 2 when playing the same source (the CBL/SAT source in my case) simultaneously. Luckily I stumbled across this and was able to rewire my zone hook ups to get by this rather unique issue I had. The remote is only semi useful. But I find the Denon iphone app VERY usable.

    Pros: Plenty of connections, including very good multi-zone support Internet connection and streaming pandora/XM-Sirius/etc works well Feature rich, about as many features as you can find at this price point

    Cons: Unit needed factory repair after only three months. That is just pathetic. The power of this unit may be disappointing to you if you are replacing another beefy-drive receiver The remote is only semi-useful. No backlight. Use the iphone/ipad app for configuration changes.

    Does not meet my requirements

    Crutchfield Customer Review (What's this?)

    Replaced an Onkyo NR808 which died shortly after warranty expired. Specifications appear to be similar but I am hoping for better quality. My configuration has 7.1 in zone 1 (living room), powered zone 2 (kitchen/dining) and line in to zone 3 (office, powered by separate amp). Setup and connection were straight forward. Note that there is no physical manual. Instead you must use the included CD or better yet download the PDF. Setup software could be improved in the area of zone management. Zone 1 up and running is short order. However, now comes the issue. It is not possible to connect a powered zone 2 and keep 7.1 in zone 1. Most competition will on-the-fly convert from 7.1 to 5.1 when zone 2 is turned on. The Denon does not have this functionality. This is an unfortunate deal breaker. So it will be exchanged for a Yamaha RX-A2020. Fortunately it is on sale for less and adds additional features. The 9.2 system will allow concurrent 7.1 zone 1 and powered zone 2. Some other thoughts: The unit is smaller and lighter than competition. Remote is not fully back lit for all buttons and feels cheap. Sound after initial setup seemed good. Did not use long enough to compare to previous Onkyo. Did not try any networking features. Overall I think this is a good unit in many ways. However, it lacks the multi-room configuration of most competition. Therefore it seems overpriced making it not the best value.

    Pros: good sound, relative easy setup of main features, smaller case than most competition

    Cons: cannot use 7.1 in zone 1 anytime if connecting powered zone 2

    What a difference!

    I upgraded to this Denon AVR-X4000 from an older entry-level Onkyo which had served me well for 6 years. The difference was astounding. I plan to upgrade my speakers eventually, but this AVR has breathed new life into my DefTech ProCinema 600 speakers. Setup was fairly straightforward, and after running the Audyssey XT32 calibration, movies and music sound clearer, cleaner, and more lifelike. The sub is much better integrated than before, with smoother, less-boomy bass. I'm very pleased and highly recommend this receiver. As usual, service from Crutchfield was flawless.

    Pros: Audyssey MultEQ XT32 Clear, clean sound Straightforward setup

    Cons: None so far

    great product

    Crutchfield Customer Review (What's this?)

    I bought this as a birthday present/replacement for my AVR-2802. AMAZING. Still learning all the new features and available apps..but after a few movies... AMAZING. Crutchfield service = AMAZING.

    Pros: Sound quality & clarity, the ability to connect a multitude of components including old definitives and polks..

    Cons: I was a little put off by the fact that the receiver is smarter than me. It told me during setup that one of my speakers was connected backwards. Really?

    Excellent Product

    Crutchfield Customer Review (What's this?)

    I am glad I bought the x4000 which is the successor of the highly rated 3313ci. The feature that sold me on the system was the Audyssey MultEQ XT32, it's a great system for correcting room acoustics and is highly recommended if you plan on running dual subwoofers. I have an open floor plan with vaulted ceilings and my previous Sony system was a pain to listen to. Because of the open floor plan I only have 3 walls onto which I can attach speakers so I opted to go with a 6.1 setup. Fronts(L/R), Center, Surrounds(L/R), Center(Back), and currently a single subwoofer. Eventual plan is to add Front Heights(L/R) and a second subwoofer. There is room for also adding Front Wides(L/R) but that might be too much. Setup was easy and the GUI is very refined and easy to understand. The included microphone is fairly long but I had to buy an extension because my room is even longer. You place it in eight different locations near the main listening position which didn't take too long. It is very important to do this while it is quiet. All I can say is that once it's calibrated the sound is amazing, dialog is a lot clearer and audible, the bass is not overpowering just the right amount at the right time, and the surround effects really envelope you. My system is mostly for movies so I have not listened to music but that will depend heavily on the type of speakers you have. Having a HDMI zone2 output is great if you also have a projector and TV in the same room as I do. ...

    Pros: Audyssey MultEQ XT32 Zone 2 HDMI output Dual Subwoofers Easy Setup 4K future proof

    Cons: None yet

    Great Receiver

    Crutchfield Customer Review (What's this?)

    I bought this receiver to replace a 6 year old Onkyo. I was going to get another Onkyo, but, after some research decided on Denon. A little further searching and I went for the 4000. I am extremely glad I did. The setup is stupid easy. The features are many and useful (wireless would be nice, but not critical). The best part, however, is the sound. I thought the Onkyo did a good job, but after listening to the Denon for a while, I realized how wrong I was.



    Flexible setup

    Crutchfield Customer Review (What's this?)

    I have an all NHT system that sounds great with this receiver. Classic 4s sound great with traditional hookup. I may biamp or run an outboard amp in the future. I really like the HDMI to zone 2, but wish it would stay connected when powered off, like the first zone.

    Pros: Value, HDMI to zone 2, sound

    Cons: Zone 2 connection not avail in standby ( as far as I know)

    Audio Features

    Equal Power Amp Design w Discrete Circuitry: The Denon AVR-X4000 is equipped with a 7 channel power amplifier rated at 125-watts (into 8-ohms, at 20-20kHz, with 0.08% THD, driving 2 channels) that reproduces high-fidelity sound in surround mode with equal quality and power for all channels, true to the original sound. The power amplifier circuit adopts a discrete-circuit configuration that achieves high-quality surround sound reproduction. To faithfully reproduce the original surround sound, each of the Denon AVR-X4000's seven channels are equipped with its own high-current power amp of equal power. Since these power amps also use discrete circuits configured with parts strictly selected for their contribution to high sound quality, rather than with low-cost integrated circuits (ICs), the surround sound playback is of impeccably high quality.

    Amplifier Assignment: The AVR-X4000's seven discrete amplifier channels can be configured to accommodate your type of home theater setup.

    • 7.1Ch (SB/FH/FW): Assigns all power amplifiers within the receiver for the Main Zone. In this configuration, up to 11 speakers (Front L/R, Center, Surround L/R, Surround Back L/R, Front Height L/R, Front Wide L/R) can be connected to the AV receiver. The receiver will automatically switch between the Surround Back (Dolby TrueHD/DTS-HD), Front Height (Dolby Pro Logic IIx), and Front Wide (Audyssey DSX) speakers based on the type of 7.1ch content. You must use separate amplifiers for Zone 2 and Zone 3 speakers.
    • 5.1Ch + Zone 2: The AVR-X4000's amplifier channels can be configured as Front L/R, Center, Surround L/R, and Zone 2 for Dolby Digital, DTS, and Dolby Pro Logic II 5.1ch playback in the main zone and 2ch PCM playback in the second zone. Surround Back, Front Height, and Front Wide speakers are not available. Zone 3 speakers must be powered by a separate amp.
    • 5.1Ch + Zone 3: The receiver's amplifier channels can be configured as Front L/R, Center, Surround L/R, and Zone 3 for Dolby Digital, DTS, and Dolby Pro Logic II 5.1ch playback in the main zone and 2ch PCM playback in the third zone. Surround Back, Front Height, and Front Wide speakers are not available. Zone 2 speakers must be powered by a separate amp.
    • 5.1Ch + Zone 2/3-Mono: The AVR-X4000's amplifier channels can also be configured as Front L/R, Center, Surround L/R, and Zone 2/3 for Dolby Digital, DTS, and Dolby Pro Logic II 5.1ch playback in the main zone and mono playback in the 2nd and 3rd zone. Surround Back, Front Height, and Front Wide speakers are not available.
    • 5.1Ch Bi-Amp: Assigns all amplifiers of the receiver to the Main Zone with the front speakers bi-amped. Up to five speakers (Front L/R, Center, & Surround L/R) can be connected to the AV receiver. The Surround Back amplifier channels of the AV receiver are reassigned to bi-amp the front speakers. A bi-amplification connection uses two amplifiers for one speaker. One amplifier is connected to the woofer section of a loudspeaker while the other is connected to the combined midrange and tweeter section. With this arrangement each amplifier operates over a limited frequency range, making its job easier. Surround Back, Front Height, and Front Wide speakers are not available. Zone 2  and Zone 3 speakers must be powered by a separate amp.
    • 7.1Ch/2Ch Front: Assigns all amplifiers within the receiver to the Main Zone for 7.1ch playback (w/ Surround Back speakers). You can also connect a second pair of front speakers that are different from the ones being used during multi-channel playback for playback of 2ch audio. The receiver will automatically switch the internal power amplifier between your multi-channel front speakers and your stereo front speakers when listening to surround sound or 2ch stereo. Front Height/Wide speakers are not available. A separate amp must be used for Zone 2 and Zone 3.
    • 5.1Ch + Front B: Assigns five amplifier channels of the receiver to the Main Zone for up to 5.1ch playback and two amplifier channels to power another pair of speakers, often called "Speaker B".  Surround Back, Front Height, and Front Wide speakers are not available. A separate amplifier must be used to power Zone 2 and Zone 3.
    • 9.1Ch (SB/FH/FW): Assigns all seven internal amplifiers to the receiver's main zone and also requires a 2ch external amplifier for 9.1ch playback. The Front L/R, Center, Surround L/R, Front Height, and Front Wide L/R speakers are powered by the internal amps. The receiver will automatically switch between the Front Height (Pro Logic IIz) and Front Wide (Audyssey DSX) speakers based on soundfield setting. The Surround Back L/R speakers will need to be powered by an external 2ch amplifier. Zone 2 and Zone 3 also require separate amps.

    24-bit/192kHz DACs + AL24 Processing Plus Technology:  This receiver is equipped with dual 24-bit/192-kHz DACs on all channels to decode and playback high-resolution recordings with less jitter and clearer sound. The AVR-X4000also offers AL24 Processing Plus for all channels (including Front L/R, Center, Surround L/R, and Sub). Denon's proprietary AL24 Processing, an analog waveform reproduction technology, expands the original 16-bit audio data to 24-bits; and can support up to 192kHz sampling frequency. AL24 Processing Plus thoroughly suppresses quantization noise (the difference between the actual analog signal and the quantized digital signal) associated with D/A conversion of LPCM signals to reproduce the low level signals with optimum clarity that will bring out all the delicate nuances of your movie & music soundtracks.

    Dynamic Discrete Surround Circuit (D.D.S.C.-HD): The AVR-X4000 is equipped Denon's Proprietary Dynamic Discrete Surround Circuit-HD, featuring a dual high-speed 32-bit floating point DSP processors for high-quality surround audio performance. All elements of the Surround Processor are optimized to the highest standards by the use of selected high performance and discrete components, particularly the A/D and D/A converters and the sophisticated DSP surround decoder.

    Hybrid PLL Jitter Reducer: The AVR-X4000 is equipped with a "Hybrid PLL Jitter Reducer" that is capable of reducing jitter and phase noise that negatively affect sound quality. The "Hybrid PLL Jitter Reducer" provided with this unit improves the sound localization, reproducing a natural sound field that is closer to the original soundtrack.

    Denon Link HD Jitter Free Audio: The AVR-X4000 also incorporates Denon Link HD, Denon's proprietary jitter-free audio transmission technology, which is designed to work with Denon's DBT-3313CI Universal Blu-ray Player (033DBT3313, sold separately). This feature separates out the timing data from the HDMI stream, allowing the receiver to re-clock the data with maximum precision, eliminating distortion-causing jitter for pristine sound quality. This technology transmits digital sound by transmitting the Denon A/V receiver's master clock signal to your DBT-3313UDCI and operating the ICs (integrated circuits) on both sides based on a shared, uniform clock signal. In digital signal transmissions over conventional HDMI connections, the ICs are operated with separate clock signals, resulting in considerable jitter and loss of resolution in the sound. Denon Link HD works not only with Blu-ray disc, but with all HDMI digital output signals; including DVD, DVD-Audio, Super Audio CD, music CD, and music streamed from a network.

    Multi-Channel Decoding Formats: The Denon AVR-X4000 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the AV receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Denon Original Listening Modes: Denon's Original Listening Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:

    • Rock Arena: For rock and popular music sources, this mode surrounds you with reflected sound of the kind you would hear at a live concert.
    • Jazz Club: This mode recreates the atmosphere of a live house where the ceiling is low and you are enveloped with rich doses of reflected sound.
    • Matrix: With this mode, you can add rich reflected sound to 2-channel stereo music sources where reflected sound is normally not audible.
    • Video Game: This mode is suited for achieving surround sound with video games..
    • Mono Movie: This mode is used when you listen to recorded monaural sound sources such as AM radio broadcasts or news programs from the center speaker.
    • Virtual: Enjoy surround effects using only the front speakers or set of headphones.
    • Multichannel Stereo: Left and right stereo channels are distributed to all the speakers so that stereo sound can be heard from all directions at any listening position.
    Note: This unit automatically generates a list of all the playable sound modes based on the input audio format and the current speaker setup configuration and displays the list on the screen. Therefore, you can select a correct surround playback mode even if you are not familiar with sound mode selection.

    Direct Listening Modes: The Denon AVR-X4000 offers two Direct Listening Modes which bypass the receiver's tone & DSP processing for higher sound quality performance. Direct Mode provides playback of 2ch or Multichannel audio in its original form, without any surround or tone processing. Pure Direct Mode goes a step further by turning off the receiver's display and analog video circuitry to minimize the possibility of any noised being added to the audio signal.

    Audyssey Technology: The AVR-X4000 features a full package of Audyssey audio technologies for optimal sound quality. Audyssey Dynamic Volume offers real-time volume adjustment, while Audyssey DynamicEQ improves your system's surround effects during low volume levels. Audyssey MultEQ XT32 automatically sets speakers and subs to suit your room's listening environment and the speakers' characteristics. The AVR-X4--- also features two Audyssey technologies (Sub EQ HT & LFC) designed to optimize bass performance. The AV receiver even offers Audyssey DSX which adds front speaker effects.

    • Audyssey MultEQ XT32: Audyssey MultEQ XT32 technology helps create an optimal acoustic profile for your home theater. Using the included setup microphone, Audyssey MultEQ XT32 measures sound levels and adjusts speaker configuration accordingly, making setup fast and easy. This room acoustic measuring and correction system analyzes (via the included microphone) the audio characteristics of your speaker system and your listening environment at up to 8 measurement points and automatically tailors the sound for top audio fidelity. You can set the Audyssey MultEQ XT to one of the following modes.
      • Audyssey: Optimizes the crossover point, output level, delay time, and equalization of all speakers based on speaker frequency response, speaker location, and room acoustics.
      • Audyssey Bypass L/R: Optimizes all speakers except front left and right.
      • Audyssey Flat: Optimizes frequency response of all speakers to flat.
      • Manual: Adjusts the tonal quality for each speaker individually using the manual equalizer settings (63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz); from -20 to +6 dB .
      • Off: Turns equalizer off.
    • Audyssey Sub EQ HT: Audyssey Sub EQ HT provides individual tailoring for each subwoofer in a dual subwoofer setup, delivering the optimum combination of highest deep bass output and lowest distortion.
    • Audyssey LFC: Audyssey LFC processing analyses and processes bass content on a continuous basis and custom tailors the sound via advanced psychoacoustic algorithms to deliver dynamic bass response within the listening room without annoying family members or neighbors in adjacent rooms.
    • Dynamic EQ: Audio engineers mix music and movie soundtracks at reference levels much louder than typical home listening levels. At lower volumes the human ear perceives sound differently; voices change, bass dissipates, and the surround effect becomes less enveloping. Dynamic EQ adjusts the frequency response curve based on volume to maintain consistent bass output, octave-to-octave balance, and surround impact, resulting in rich sound at any volume. You can set the Dynamic EQ to 0, 5, 10, or 15 dB.
    • Audyssey Dynamic Volume: Audyssey Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Dynamic Volume addresses the issue of commercials that are too loud and movie soundtracks with vast differences between soft and loud passages; the results are more intelligible dialogue, loud passages maintain impact, and soft whispers are heard clearly. When the volume level changes, Dynamic EQ also adjusts the frequency response to maintain sound quality. You can set the Dynamic Volume to Day (low), Evening (middle), Midnight (high), or off.
    • Audyssey Dynamic Surround Expansion (DSX): Audyssey DSX adds front effect speakers to improve spatial sound reproduction. Starting with a 5.1 channel system, DSX adds front Wide and/or front Height channels for better sound staging (although both wide and height speakers can be added, only one pair is used at a time). DSX also applies Surround Envelopment Processing to enhance the blend between the front and surround channels.

    Surround Parameters: You can adjust the following surround mode parameters:

    • Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust:
      • Panorama: Broadens the front stereo image to the surround speakers to provide a wraparound effect, especially effective when there is limited output from the surround channels, panorama can be turned on/off in the menu.
      • Dimension: Allows you to move the sound field forward or backward.
      • Center Width: Allows you to adjust the width of the center channel.
    • Center Image: In the Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
    • Denon Original Surround Mode Settings: While listening in one of the Denon Original Surround Modes, there are three further enhancements you can adjust:
      • Room Size: This feature allows you to set the size of your desired acoustic environment when using specific Denon Original Surround Modes; select Small, Medium small, Medium, Medium large, or Large.
      • Effect Level: This function adjusts the effect signal level from 1 to 15 when using specific Denon Original Surround Modes.
      • Delay Time: This feature adjusts the delay time (0-300ms) to control the sound stage size.
    • Height Gain: Adjust the volume (Low/Mid/High) of the Front Height channels in Dolby Pro Logic IIz.
    • Audyssey DSX Settings: While listening in the Audyssey DSX audio format, there are two further enhancements you can adjust:
      • Stage Height: adjust sound stage height (+/-10) when using front height speakers
      • Stage Width: adjust sound stage width (+/-10) when using front wide speakers
    • Center Gain: During DTS NEO:X, this function distributes the dialog output from the center channel to the front left and right channels and widens the sound image in t he front.

    Audio Enhancements: The Denon AVR-X4000 receiver provides various audio enhancements to deliver a high-quality listening experience every time.

    • CINEMA EQ (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Digital, DTS, Dolby Pro Logic (including PL II, PL IIx, PL IIz), and DTS Neo:6 modes.
    • Restorer: Compressed audio formats such as MP3, WMA (Windows Media Audio), and MPEG-4 AAC reduce the amount of data by eliminating signal components that are hard for the human ear to hear. The Restorer function generates the signals eliminated upon compression, restoring the sound to conditions near those of the original sound before compression. It also corrects the sense of volume of the bass to obtain richer sound with compressed audio signals.
    • Dynamic Range Compression (DRC): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, Compressing the dynamic range allows you to hear all of the sounds in the soundtrack with reduced dynamic range. DRC works when playing program sources recorded in Dolby Digital or DTS.
    • Tone Settings: You can independently adjust the system's overall Bass and Treble settings from -6 to +6 dB.

    Volume Settings: The AVR-X4000 offers the following volume settings.

    • Volume Scale: You can choose to display an Absolute volume scale (0-98) or Relative volume scale (-79.5 to 18dB).
    • Volume Limit: You can set a maximum volume level of 0, -10, or -20 dB to limit the receiver's total volume output.
    • Power On Level: You can define the volume setting that is active when the power is turned on (0, 1-98, -79 to +18dB, or Last)
    • Mute Level: You can set the amount of attenuation for the audio muting circuit; -40dB or -20dB below current volume, or full mute (sound turned off entirely).

    Level Adjustments:  The AVR-X4000 provides the following level adjustments.

    • Source Level: This function adjusts the playback level of the currently selected input source's audio input. Use this feature if there are differences in the input volume levels between different sources. You can correct the playback level of the audio input from -12 to +12dB.
    • Dialogue Level: You can adjust the output level (+/-12dB) to clarify the dialogue output from the center channel.
    • Subwoofer Level: You can set the receiver's subwoofer output level (+/-12dB) independent from the other speaker levels and system's main volume.

    Audio Inputs/Outputs: The Denon AV receiver offers a variety of analog and digital audio inputs/outputs.

    • Assignable Digital Inputs: The AVR-X4000 features two optical digital (Toslink) inputs and two coaxial digital inputs. Each input can be assigned to any of the different input sources, except Tuner.
    • Speaker Terminals w/ Color Labels: The receiver has binding-post terminals for all speaker connections. The binding-post terminals can accept bare wire, pin connectors, and banana plugs (single/dual). The receiver will accept speaker impedances of 6 to 16-ohm. The AV receiver comes with color labels to easily identify which channel a speaker cable should be connected to. Since the speaker cables have labels in the same colors as the connectors on the AVR-X4000's rear panel, there's no longer any confusion about which terminals they should be connected to.
    • 11.2Ch Pre-Outs: The AV receiver features 11.2ch pre-amp outputs (Front L/R, Center, Surround L/R, Surround Back L/R, Front Height L/R, Front Wide L/R, and Dual Subs) for connection to external power amplifiers.
    • Phono Input: The Denon AVR-X4000 is fitted with a Phono input (MM), so you can connect your turntable and listen to your vinyl records with high-quality sound.
    • Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.

    Video Features

    7 HDMI Inputs/3 HDMI Outputs: With seven HDMI v1.4 inputs (6 rear/1 front), the AVR-X4000 allows you to route multiple high-definition devices, such as your Blu-ray player and cable/satellite receiver, to your TV. It also allows you to connect all of your devices to up to three TVs with a HDMI cable (via its three HDMI outputs; two parallel and one discrete), reducing cable clutter. The two parallel HDMI outputs distribute the same video signal simultaneously to two separate displays. The discrete HDMI output allows you to play a different audio/video source in another zone. The HDMI inputs are assignable to different input sources. The receiver's HDMI v.1.4 jacks are compatible with 1080p/24Hz & 4K video, 3D video signals, Deep Color & x.v.Color technology; as well as LipSync, ARC, and HDMI control.

    • 3D Pass-Through: With the advent of 3D media, it is important to own a receiver that recognizes 3D video signals. The AVR-X4000 is able to pass through 3D signals from your Blu-ray player, ensuring that the 3D effect doesn't get lost in translation. It also recognizes signals from 3D television broadcasts. By connecting a 3D-compliant Blu-ray disc player and 3D-compliant TV to the AVR-X4000, you will have a 3D home theater where you can enjoy high-definition sound and video on a level you've never experienced before.
    • Deep/x.v.Color Support: The AVR-X4000 also supports Deep Color and x.v.Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture.
    • LipSync: If needed, the audio signal can be manually delayed to match the video signal; adjust from 0-200ms.
    • ARC (Audio Return Channel): This feature allows audio to be sent from your compatible HDTV to your receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television.
    Note: The AV receiver's HDMI 2.0 jacks do not support the latest HDCP 2.2 copyright protection for 4K ultra-HD content, so it will not support 4K content from satellite/cable providers, online video services, and Blu-ray disc which are copyright protected with HDCP 2.2.

    4K Pass-Through + Video Upconversion: The Denon AV receiver's Analog Device 12-bit video processor (ADV8003) supports pass-through of 1080p/24Hz and 4K Ultra HD video. This sophisticated video processor also provides upconversion from standard definition (480i/480p) and high definition (720p/1080i1080p) sources to 4K Ultra HD (3840x2160 pixels), which lets you connect all your analog (composite/component) or digital (HDMI) video sources to the AVR-X4000 and then connect to your HDTV with just a single HDMI cable.

    Note: The receiver's HDMI Zone 2 output does not support analog-to-HDMI conversion, nor does it support HDMI-to-HDMI scaling.

    HDMI Standby Pass-Through: When enabling the HDMI Standby Pass-Through function, regardless of whether the AV receiver is "On" or in "Standby" both audio/video streams from an HDMI input will be output to your television, via the receiver's HDMI monitor output. You can select between three HDMI through function modes.

    • HDMI Input: Selects the HDMI Input (1-4) for which the HDMI Standby Pass-Through function is enabled.
    • Last: The HDMI Standby-Through function is activated on the input source selected at the time of setting the AV receiver to the "Standby" mode.
    • Off: The HDMI Standby Pass-Through function is disabled.

    InstaPrevue: HDMI InstaPrevue Technology provides live video thumbnails of the available content on your devices connected to the receiver via HDMI 1 through 6 inputs (the HDMI 7 input does not support InstaPrevue). As a result, you can preview audio/video streams coming from up to 5 HDMI inputs previously assigned to input selectors on your HDMI connected TV, while enjoying viewing another source input.

    Analog Video Inputs: The receiver features four composite video inputs (3 rear/1 front) and one composite video output. There is also two component video inputs and one component video output (60MHz). The composite and component video outputs can be used as monitor outputs or Zone 2 outputs.

    Picture Mode: The receiver provides Picture Mode to adjust the picture quality for your viewing content and environment. You can select from Standard, Movie, Vivid, Streaming, Custom, or Off. The Custom mode lets you manually adjust Contrast, Brightness, Saturation, Hue, Noise Reduction, and Enhancer (sharpness).

    Video Select Function: While listening to Network/Tuner/USB content, you can switch the receiver's video input so you can display video while listening to an audio source.

    I am bi-amping a pair of Klipsch RF-82 ii's and am very happy with the sound. I've never done a direct comparison without bi-amping, so I can't objectively tell you what I'm gaining. I only have 2 surround speakers running (and for room reasons cannot add more) losing the 2 surround channels is not a difficult decision for me. So I'm happy with the bi-amping. You'll have to decide if you are willing to lose the surround back. [ STEPHEN  Mar 18, 2015 ]
    bi amp effectiveness is dependent on the quality of the crossovers in your speakers, my polk monitor 70s really improved with bi amping enough so that i gave up on 7.1 and went with 5.1. [ Daniel  Mar 11, 2015 ]
    I have 9 speakers now. I discovered that the DVR-W4000X, even though it has 11 speaker hookups, only can drive 9 speakers. :( So if I bi-amp, then I'll actually be turning off 2 speakers. The article doesn't address what is gained by bi-amping. I'd like to find a comparison of that. To Bi-amp or not to Bi-Amp. [ Jason  Mar 11, 2015 ]

    reciever controls vol on zone 2 & 3, I run 5 rooms with 2 speakers each. I only have 5 channel main, don't think you can do 7.1 and second zone at the same time. [ JOHN  Feb 19, 2015 ]
    Channels 2 & 3 are volume controlled through the AVR-X4000. You have to switch to those zones, but once there the volume can be used to control the level. [ STEVE  Feb 18, 2015 ]

    Thanks, I guess it's time to look at other brands. [ Darrell  Feb 05, 2015 ]
    Sadly, there is no Bluetooth nor wifi. The Ethernet port is 100mbit, which is sufficient, but underwhelming for a product of this nature. The entire web interface is functional, but slow and looks 'old'... Otherwise, the receiver has been excellent. [ STEVEN  Feb 05, 2015 ]
    I'm not running that way, mine is set up in 5.1 for the main zone, however both the manual and the unit's setup menu shows the max output as 9.1. Seven would be powered directly, with the remaining two from the preamp which can be set to Surround Back, Front Height, Front Wide, or Front. It doesn't appear it will drive all 11 at the same time, even though it has physical connections for 11 speakers. [ RANDALL  Dec 15, 2014 ]
    Sorry, all I can do is IMHO this question, and my HO is of no real value to him -- sorry. [ Richard  Dec 15, 2014 ]
    Sorry, Never tried. [ RICHARD A.  Dec 06, 2014 ]
    Yes I have my front speakers Biamp using the surround zone. [ CARLOS  Dec 05, 2014 ]
    Not sure. [ Lewis  Dec 05, 2014 ]
    Now that I've lived with the av receiver and have it fully installed, I can confirm that you can play two different video sources in the main and 2nd zone with separate audio in zone 3. The hdmi does carry the video/audio to zone 2 to play on the tv speakers. My tv has digital audio out that I could run to a separate receiver. Thanks. [ Scott R  Dec 25, 2014 ]
    I don't think I can fully answer your question since I don't use Zone 3. However, I'm fairly certain Zone 3 will not work independent of the main zone without separating some channels. In other words, I don't think you can watch tv on zone 1 with 5.1 and watch tv on zone 3 independently. You may have to assign a channel to zone 3 to get audio to your HDMI. Sorry I couldn't be more help. [ MICHAEL  Dec 25, 2014 ]
    HDMI is Video and Audio. In fact it's 2 way. HDMI cable has a reverse channel and tells the amp what resolution your TV will support. [ THOMAS A  Dec 05, 2014 ]

    I have not tried any 4 ohm speakers: however according to the owners manual you should use speakers with an impedance of 6 to 16 ohms [ EDWARD  Nov 26, 2014 ]
    After checking my manual which lists specifications for 8 ohm and 6 ohm speakers, I contacted Denon Tech support to get the answer which is "NO" the AVR-X4000 receiver is not rated to support 4 ohm speakers. Sorry for the bad news. Michelle [ MICHELLE  Nov 25, 2014 ]
    This receiver is not recommended for use with 4-ohm speakers. The minimum impedance (as recommended by Denon) is 6-ohms. [ Jeff  Nov 25, 2014 ]  Staff
    Steve, Although I don't currently run 4 ohm speakers, I want to say this receiver does support. I can confirm this later today. The receiver is nice however it requires heat disapation as at high volume levels she heats up. Also....if your use to a lot of manual sound tweaking, you might be disappointed. The sound is really good, however you are fairly restricted into category sets with very little manual override ability. Hope this helps, and I will attempt to confirm the 8 ohm requirements [ MICHAEL  Nov 25, 2014 ]
    I only use this receiver in my home theater and cannot try what you are asking . however the user manual is available on denon web site and might be helpful. ed [ EDWARD  Jul 17, 2014 ]
    Hey Greg, I don't have mine set up that way, but it should be able to handle that requirement, if not, by adding an amplifier to zone 2 would give you the power to drive the system. I am very happy with the receiver. [ THOMAS S  Jul 17, 2014 ]
    Yep/ and it can be two different digital sources, not just an analog along with the 5.1. So you can watch a blu ray in one room and have apple airplay in the other at the same time. This truly is a fantastic reciever. [ JOHN E  Jul 17, 2014 ]
    The minimum speaker impedance listed for this receiver is 6-ohms. Based on the info you have provided I would recommend contacting an Advisor by phone or online to discuss your system plans. They'll be able to discuss your system plans and make sure everything will work out okay. [ Jeff  Dec 19, 2013 ]  Staff
    As far as I know the AVR-X4000 can only be used as the airplay "slave" device, meaning it can receive/play a stream from a "master" device such as your PC with itunes. I don't believe the AVR-X4000 can send a stream to another airplay "slave" device such as an airplay speaker in your kitchen. [ KEN  Dec 10, 2013 ]
    All in all, I was looking at this unit but may end up getting the Marantz 7008 instead, not so much for the extra amplifiers but for the higher quality components and longer warranty. The free unit that comes with the 7008 looks nicer as well. [ Photonian  Dec 10, 2013 ]
    Yes, you must activate airplay in the main zone first, then switch on zone 2 [ GLENN  Dec 10, 2013 ]
