Manufacturer description
D.D.S.C.-Digital is a circuit configuration specially designed by DENON in which all elements of the surround processor are optimized through the use of selected high performance discrete components, including separate A/D and D/A converters, with sophisticated DSP surround decoding. New D.D.S.C.-Digital incorporates the latest devices and also DENON LINK digital circuit. For decoding and processing various digital signals with the highest level of accuracy, DENON developed new 32bit floating point DSP for the AVR-3805, so this new D.D.S.C-Digital circuit provide the ultimate in multi-channel performance. DENON LINK has just been upgraded to the 3rd edition. The new edition now allows the input of Super Audio CD digital signals as well as DVD-Video/Audio. To transfer audio signals, DENON has developed a unique digital transmission technology, known as DENON LINK. This digitally balanced transfer technology permits jitter-less data transfer and low noise. The AVR-3805 incorporates this latest digital audio interface, so the end user will experience absolute finest in audio playback between AVR-3805 and DENON LINK featured DVD player. This video transcoding to component signals, letting you enjoy high picture quality from all video gear connected to the AVR-3805. Since composite and S-video signals are also converted into component video signals and output to the monitor, all you need to do is connect a monitor that can display component video images. The AVR-3805 is equipped with auto set up and room equalizing capability to achieve the ideal sound field for your room. With the microphone placed on your listening position, the powerful new 32bit floating point DSP analyzes accurately and automatically adjusts and sets the speaker configurations for your listening room. Also AVR-3805 analyzes the frequency response with 8 band parametric equalizer and adjust to optimum sound field. The microphone is equipped high performance microphone unit and heavy duty base to suppress the vibration for accurate analyzing. Pure direct function is designed for audiophiles to enjoy the audio sources. This function turns off the video circuit and FL display and also digital circuit while the analog playback. While you playback PCM source, DENON's waveform technology AL24 plus processing is worked and bring out all the delicate nuances of the music. The AVR-3805's remote controller is completely new designed for easy to use. It is featured EL technology, and it gives you a sophisticated design and control. The AVR-3805 features an equal power 7-channel amplifier section, with identical amplifier design on all 7 channels, with high current discrete output devices on all channels. Each of the 7 amplifier channels is rated at 120 watts, into 8 ohms, from 20 Hz - 20 kHz with no more than 0.05% THD. A huge power transformer has been connected in the power section where it is combined with a rectifier diode and a large block capacitor to ensure a large, stable supply of electrical current. Accordingly, the AVR-3805 boasts high output power of 120 W for each of the 7 channels. A large-capacity block capacitor was developed for the AVR-3805 to ensure a rock stable supply of power. The AVR-3805 provides a Multi Zone Output function and a Select function that let you output different sources to multiple zones. Sources can be selected for output to an additional zone, in addition to the main room. Multi-room Zone 2 can have variable pre-amp output along with composite video feed. And an independently selected source can be output to Multiroom Zone 3 as a fixed output. The AVR-3805's Power Amplifier Assign function lets you assign the 2 or 3 Surround Back (SB L/R) amplifier channels when the system is not configured for 7.1, to instead drive the Multi-room Zone 2 speakers, with 120 Watts per channel output power, while still providing 5 discrete amplifier channels to drive all speakers in a 5.1 configured home theater room.Product summary
The good: A 7.1-channel receiver; high-end style and feel; graphic-display remote; all-digital hookup for compatible Denon SACD/DVD-A players; turntable input; versatile surround speaker switching.
The bad: The included superslick universal remote may be too advanced for its own good.
The bottom line: Audiophiles craving the very best sound and cutting-edge features will find everything they need in Denon's AVR-3805.
Editors' review

Editors' note: Denon Electronics will not honor the warranty on components purchased from unauthorized dealers or if the original factory serial number has been removed, defaced, or replaced. If in doubt about a particular online or brick-and-mortar retailer, call Denon at 973/396-0810.
Denon has jazzed up its conservative style, and we must say, the AVR-3805 oozes class. It weighs a hefty 37.5 pounds and measures 17.1 inches wide, 6.5 inches tall, and 16.75 inches deep. The receiver is available in black or a lovely dark silver finish.Denon's Auto Setup feature eases setup hassles by confirming speaker phase, assessing the sizes of all of your speakers, measuring speaker-to-listener distances, and balancing speaker levels. The catch: you need to buy Denon's optional mic (or use your own compatible mic--click here for PDF) to take advantage of the Auto Setup feature. The first time we ran Auto Setup, it wasn't as accurate as the automatic leveling found on Pioneer's much less expensive VSX-D914-K. We reran the test a few times before the AVR-3805 got it right. OK, it may not be perfect, but it's much better than not doing any setup at all.
The AVR-3805's large remote deserves special mention. Other than its four buttons and centrally located cursor controls, the touch-screen remote features two large blue membranes that light up whenever you pick up the remote. Press Amp, and the remote displays receiver-related controls; press DVD, and the remote displays a full set of DVD controls such as Play, Pause, Menu, and a complete numeric key set--everything you need to operate a DVD player. (The design is similar to the contextual soft keys found on One For All's line of Kameleon universal remotes.) The remote looks really cool, but we think some buyers, especially those who prefer to navigate by touch, might prefer a standard remote with buttons.
The Denon AVR-3805 offers seven 120-watt channels and a boatload of surround processing modes, including Dolby EX and Pro Logic IIx, DTS ES, and 96/24. It also includes HDCD processing that enhances the sound of special HDCD-encoded CDs.Extensive equalization options can help ensure your speakers sound as good as they can in your room. We're skeptical about the real-world usefulness of auto EQ (equalization) systems because they so rarely improve sound quality, but the AVR-3805's EQ did just that. The equalized sound not only produced more detail and smoother bass response, the speakers' imaging focus was sharper with the EQ turned on.
Otherwise, connectivity is on a par with separate preamplifier/processors selling for three times the price of the AVR-3805. The Denon Link offers a single-wire, all-digital hookup path for a few compatible higher-end Denon SACD/DVD-A players. That's nice, but most of us still have to run six analog cables between our SACD/DVD-A players and the receiver's 7.1 channel inputs. The receiver can upconvert your S-Video and composite inputs (from VCRs or older cable boxes, for instance) to component-video output. Other back-panel highlights include component-video switching for three sources, a turntable input, second and third zone multiroom capability, six digital audio inputs and two outputs, and an RS-232C port for use with AMX or Crestron home automation systems.
The AVR-3805 is the first receiver we've tested that offers a choice of switching between the two sets of surround speakers (the side back channels and the rear back channels) when in 5.1 mode. It's yet another customization option that audiophiles with refined tastes will appreciate (see the Performance page for more details).
And finally, we were happy to see that Denon included a group delay of up to 200 milliseconds so that you can reestablish lip sync with video displays that lag behind audio signals.
The surround-sound capabilities of this receiver are truly awe inspiring, but we started our auditions in stereo. Roseanne Cash's 10 Song Demo CD sounded pristine, with Ms. Cash's vocals and acoustic guitar holding center stage between our Dynaudio Contour speakers. The Denon AVR-3805's lush sound mimics high-end separate components.To test the AVR-3805's surround stamina, we played Pink Floyd's Dark Side of the Moon SACD. We felt the album's opening heartbeats before we heard them. On "Time," the clocks' ticks 'n' tocks, and various chimes and gongs filled every corner of our home theater--even the screaming lunatic's rantings were clarified by the AVR-3805's revelatory sonics.
Switching between the A side surround speakers to the B rear surrounds demonstrated the wisdom of Denon's versatility. Fact is, most of our multichannel music discs sounded better with the rear surround speakers turned on; DVD movies were better with the side surrounds in play. Of course, for those few DVDs encoded with 6.1/7.1-channel Dolby EX or DTS ES soundtracks, you can run both side and rear surround speakers. Assuming you have a room large enough to set up side and rear surround speakers, the AVR-3805 is uniquely capable of delivering the best from movies and multichannel music.
Our DVD pick, Wonderland, turned out to be an awful druggy movie about a Hollywood murder spree involving legendary porn star John Holmes. But the soundtrack was loaded with room-shaking, low-frequency effects and the drug-induced surround effects spun around our home theater. The film's physical brutality was conveyed with convincing power by the AVR-3805.

Not what I expected from Denon
Pros: Very nice AV Receiver
Cons: I own it from 2005 and had to have in Service three times already. Not what I expected from Denon. Problems with digital and optical inputs from Denon DVD Player, Samsung LCD TV, Motorola Cable box.

Perfect for ME.
Pros: DenonLink, Plenty of Power, great build quality, beautiful looks.
Cons: No HDMI switching. Do NOT like remote.
OK, the remote aside, this unit performs exceptionally well. This is the 2nd Denon receiver I've owned and it wowed me MORE than the 1st Denon receiver I've owned which was an AVR-2000 back in '93. I use 3 sets of surround speakers with this unit. I run 7.1 with 2 sets of dipole surrounds for movies. Then I have a 3rd set of surrounds that are direct firing speakers that I use for 5.1 channel Hi-resolution music via DVD-Audio and SACD. It sounds like alot but the 3805 can handle all of it. That and I'm single so no one is yelling at me for having that many speakers on the walls.LOL.
All in all this the best AV receiver I have ever owned to date. I paired this with the Denon DVD-3910 universal player which has HDMI outputs so for transferring HDMI video so it matters not that the 3805 has such inputs and outputs.

Jameson Thottam --- Critique on Denon 2805
Pros: Jameson Thottam: Incredible sound performance, cool backlit remote.
Cons: Jameson Thottam: No set set up mike and for this price bad idea!
This Denon 3805 is a monster! I let go of a Onkyo TX-DS 797 to get to this sonic marvel. I'd heard how complicated these
recievers were and all the talk of how hard it was to understand the manuals and all that but i tell you, you have to experience one for yourself. Set mine up myself oh also not including the setup mike was in my opinion a major blunder but i did alright myself. I suppose i will have to break down and purchase one just to see how well it works.
Summary: Jameson Luke Thottam
And as far as the remote it takes some getting use to and all but it is very cool you love it or you hate it as they say i love mine! As i said i thought i had reached a certain level with my Onkyo but this Denon made a believer out of me.

Instant Home Theatre Upgrade
Pros: Fantastic sound reproduction. All the hookups you'll ever need. Versatile setup. Well made!
Cons: Not for the faint of heart, setup can be a little tricky. Pricey A/V component, but well worth it for anyone looking to make an instant upgrade to their home theatre.
The 3805 is a remarkable piece of equipment. When I purchased it, I planned to pair it with a complete top of the line Polk speaker system. I realized the speakers were much to large in size for the area I was planning on using them and "settled" for the Bose Acoustimass 15 speaker set.
The sound reproduction was (is) absolutely incredible. I truly think you could hook-up homemade speakers to the 3805 and you would have great results.
The 3805 has an incredbible selection of hookups...optical, RCA, component video, composite video, S-Video and the Denon Link (proprietary). It can be adapted to fit 5.1, 6.1 or 7.1 speaker formats. The major decoders are built in (DTS and Dolby) with multiple formats for both.
The only issue I had with the 3805 is the setup. It can be a little tricky setting which connections you want to go with the presets (TV, DVD, VDP etc.). Beyond that I had nothing but bliss watching movies and playing X-Box.
If you're in the market for an affordable high-end INSTANT upgrade to your existing home theatre, this is a no brainer.

Cons: Ah, that learning curve thing, again!

Outstanding features and performace.
Pros: Auto Parametric Equalizer is "The Bomb"
Cons: Owners Manual Needs the "3805 for dummies" version
I've owned the 3805 for a little over a year and boy did I find something out! Are you ready folks? The "Mode" button on the front lower left-side panel holds a key. When you push this button in succession you get 3 choices: 1)"PCM", 2)"AUTO", and 3)"DTS".
Well, not wanting to set this button manually everytime I move from a DVD to a cd, I had the setting set on "Auto" so that the receiver would auto-detect the correct input format on it's own. Then one day I was messing around with the 3805's front panel settings while a regular CD was playing on my DVD player. When I changed the input "mode" button from "AUTO" to "PCM" the sound instantly improved. The dynamics, transparency, and soundstaging all opened up and I was listening to my equipment in all it's splendor for the first time! I couldn't believe what I was missing for the last year or so.
Apparently, the input signal when set to "Auto" has to go through some extra circuitry that seriously degrades the sound. My advice is don't be lazy, get off your chair and set this manually to the needed input mode each time you change from DVD to CD. Please let me know if others discover this.

Way to go Denon!
Pros: Amazing feature set for the price, clean conservatively rated power supply.
Cons: The remote, what were they thinking?
out of 52 user reviews
It takes a m week or two, but they wait & learning curve are worth it !
Pros: Auto setup, make sure your speakers are matched or you never get the correct sound
Cons: Documentaion and manuals are basic.
My first two weeks I was waiting for center channel speaker to arrive on backorder. I could never get the Denon 3805 to right. But when my Defintive Tech CLR 2500 arrived I hooked it up, drug out that microphone again and poof, the low range blended. I might add by this time I was getting quite familiar with all the options the 3805 had to offer. It seems to me that if a Reciever dose'nt have enough two months later I feel like I've under bought two many features as we are seeing today has a learning curve. Now 3 months later I very happy with 3805 and I really have'nt been a Denon fan for over 10 years. Today I have no regrets Dollar for dollar I feel like this was a solid deal and would recomend it to any one in the $1000 price

really incredible sound
Pros: just incredle sound - brought new life to a pair of Polk speakers, video upconverting is very handy so you don't switch inputs on your TV
Cons: With so many inputs, I wish you could disable some or have a favorites list so you don't cycle through 8 choices when you only have 3 (VCR, HDTV, DVD).

A formidable cornerstone of a quality AV system
Pros: Auto-setup does good (not quite perfect) job of correcting acoustic limitations of speakers/rooms. Excellent sonic clarity. Very flexible and configurable. Ample power and negligible distortion.
Cons: Remote is a love/hate relationship. Requires some investment of time for maximum benefit. Manual limited by poor translation and scant explanation.

great AV system
Pros: This was an upgrade from AVR-1600. Kind of like going from a Ford Escort to a Ford GT-40. Unbelievable sound. Beautiful video handling. Enough inputs in the back to plug everything into the AV unit. Makes my Paradigm speakers sound great.
Cons: The remote is a joke. Whoever thought that this was the right direction must have been sniffing new plastic or something. Membrane covered push buttons went out in the 70s. With daily use, there'll probably be a hole in the amp spot within six months.
