Our take on the Denon AVR-2805

With ultra-clean amplification for up to seven home theater speakers, Denon's AVR-2805 fills your room with sweeping, cinematic sound. It's also got a brainy 32-bit SHARC processor that drives ultra-precise Dolby® Digital EX, DTS-ES®, and Dolby Pro Logic® IIx decoding. You'll be able to turn any stereo or surround source into enveloping 7.1-channel audio.

With ultra-clean amplification for up to seven home theater speakers, Denon's AVR-2805 fills your room with sweeping, cinematic sound. It's also got a brainy 32-bit SHARC processor that drives ultra-precise Dolby® Digital EX, DTS-ES®, and Dolby Pro Logic® IIx decoding. You'll be able to turn any stereo or surround source into enveloping 7.1-channel audio.

Denon's new Auto Setup and Room EQ Adjust takes the hassle out of speaker configuration. Just plug in the included microphone and place it in your favorite listening seat. The '2805 then uses a series of test tones to balance speaker levels and fine-tune the delay and EQ settings for each speaker. The result is optimized system performance for your specific home theater room!

Sixteen Analog Devices 192kHz/24-bit digital-to-analog converters handle your digital sources with extreme precision. Pure Direct mode shuts down all unused circuitry for the cleanest possible stereo sound from any audio component in your system. Another high-end bonus is Denon's ALPHA 24 Processing Plus, which uses sophisticated upsampling to produce analog smoothness from stereo digital audio.

Dual-room/dual-source output lets you enjoy 7.1 home theater surround in your main room while housemates enjoy another music or video source (in stereo) in a second room. You'll need a separate amplifier for your second listening room — or, if you step to 5.1 audio in your main room, the AVR-2805 can also power a pair of second-room speakers!

Loads of inputs and outputs let you build a massive system around the '2805. You get 7 digital inputs, 7 A/V inputs, a 7.1-channel preamp output for system expansion, and a 7.1-channel input that keeps you ready for future formats. Component video conversion greatly simplifies hookup to your main-room TV and lets you preserve maximum video quality for all sources. The learning/multibrand remote with glow-in-the-dark keys provides easy control of your entire system.

Still Going

matt from Winooski, VT on 12/26/2013

Well it's almost 2014 and the thing is still going. There are some things that are clunky about it, the remote, switching modes/inputs. It sounds good. The 'pure direct' thing is pretty cool. Who knows how good it works? Could be a gimmick. New newest tech it has is optical..which doesn't have the greatest bit rate. For its time, it was a good deal. Coming up on ten years and nothing went wrong with it! A TANK!

Pros: Lots of watts. Lots of ins and outs. Pure Direct mode. Great sound.

Cons: Remote ridiculous. Tech went obsolete quickly.

Terrific product

Great equipment, bad manual

Rick Johnson from Roseville,CA on 5/31/2005

Crutchfield Customer Review (What's this?)

I recently bought the Denon AVR 2805 and hooked it up. It works great. I can finally take full advantage of my multi-room sound system and still get great theatre sound (5.1) in the family room. I do have 2 complaints: the remote and the manual. The manual is terrible. Denon should be able to afford to hire someone who ACTUALLY speaks english. It didn't take me long to get the system hooked up electronically, but it took forever to figure out how to use it. Even after I deciphered it, the information was poorly organized and insufficient. The remote is not much better. I'm sure it has all of the necessary functionality, if I can just figure out how to use it.<BR><BR>There, I've vented my frustrations. The hardware is great so far. It's a relief to be able to connect audio that uses a mixture of connectors (composite and both coaxial and optical digital) and have it work flawlessly. Of course, I couldn't get Dolby PL on the non-digital devices at first. It seems that you have to configure each connection and that little fact was buried in the manual.



Denon AVR-2805

Crutchfield Customer Review (What's this?)

I have been a hi-end audiophile for many years during which I have owned separate amp-preamp units from Krell, Audio Research, Creek, McIntosh and speakers from Thiel, B&W, Klipsch. At this point in my life I have been going to Home Theater and surround sound and getting away from the hi-end stuff. I have sold most of the expensive equipment and finally bought a DENON AVR2805 after listening to several other receiver brands through my sweet B&W 805 Matrix speakers to which I added the center and surround units. At 100 watts per channel this DENON convinced me that modern electronics are amazing and DENON has the lead in this field. Sound is so fine and detailed as are the many features that I never had with all that hi-end HiFi over the years. I am looking forwards to listening to my old CD's and even my older tapes thru this setup.




Gregory from Gadsden,Al on 4/12/2005

Easy to get 7.1 sound out of normal stereo tv using the dolby pro logic 2x mode. It really rocks on a 6.1 encoded dvds or something in dolby digital. The auto setup with the mic works great. The component switching works great also. Great thing about this receiver is being able to put any of the digital sound inputs to any of the video inputs so you are not limited with choices. I also bought the Infinity TSS-750 5.1 home theater speaker package and I added 2 more speakers to make it 7.1. They sound amazing with this receiver, i hear highs and lkows I never heard before. I am very happy with my purchase.<BR>The only thing I dont like that my old receiver did was let you change the name of the inputs from vcr2 to something like xbox, but I guess I can live with that.<BR>



Great product

Crutchfield Customer Review (What's this?)

I upgraded this unit from a JVC 5.1 unit that I thought was fine but wanted two more channels and Prologic II. Wow! I could not believe the difference! I did not believe you could get this kind of performance at this price point. The auto set up AND ROOM EQ is great, and so close to RTA measurements that you would have to have an RTA to fine tune any better. I am using a Denon DVD player and Infinity Primus 150's all the way around with the matching Infinity Primus center channel and the Infinity Primus 12" sub.<BR> All purchased from Crutchfield, as always thier service was great.<BR> For an impressive surround system on a modest budget this is one to look into.



why go out to the movies

nugget from galveston on 3/30/2005

I upgraded my home theater from a harmon kardon 335 with jbl northridge series 5.1 speakers to the denon 2805 with anthony gallo 7.1 surround sound package" 4 nucleus micro's,3 due's,and the mp10 subwoofer".All i can say is WOW!The sound i get is nothing short of incredible.I get seperation of sounds like u wouldnt believe.A match made in heaven.This receiver really rocks!<BR> The only down side to this reciever is that it doesnt have hdmi inputs.



Great Product

Crutchfield Customer Review (What's this?)

This is a great sounding unit. I'm completely impressed. Two thing that I did not like. The manual is almost mpossible to understand and the remote is a even worse. <BR><BR>I suggest purchasing a Harmony 659 remote. It costs $150 but is well worth it. The Harmony sets up through their web site and is very intuitive to use. Too bad Denon can't include a decent remote with their $900 receiver. Or even better, keep their lame remote and sell the unit for $100 less.




Lamont from California on 3/3/2005

All I can say is wow. Worth every penny. I upgraded from the JVC 803 and I have been amazed at the difference in sound. Like everyone else says, dont be fooled by the 100 watts per channel. My average sony speakers have come to life and my SACDs sound great. I purchased the Denon 2910 DVD player to match this receiver. I hear things I never heard at first. You can control almost every little detail of sound and I'm in love with the learning remote. After purchasing the receiver and DVD player I told my wife if she didnt hear a difference in sound I would box it up and keep my old equipment. She too was amazed at the power and clean sound from this unit. I used to be hooked on JVC but now I know what I've been missing. I have no complaints about this unit and will not even think about upgrading from this baby. It's true what they say, you get what you pay for. It's hard to spend $900 on a receiver but to me it's worth every penny.




Demonspeed21 from Jacksonville,NC on 2/25/2005

WOW!I started out with a Denon AVR 1803.I just recently upgraded to the AVR 2805.If you have never experienced full bandwidth,high current amplifiers before,you are in the stone age.The 7 amplifiers in this unit is the key to the mind blowing power and clarity this unit puts out.Don't let the 100 watts per channel fool you.because the unit has a seperate amp for each channel makes the 100 watts equal to 200++watts from any other system.The automatic setup feature with included mic makes setup idiot measures the sound from each speaker and tunes them to fit your room.Talk about room to grow!99%of all DVD's are 5.1.This unit is 7.1.You haven't heard true surround sound until you have heard DTS ES6.1 discrete playback.The sound quality equals ANY multi-plex.If you want the best sound,in a unit that is a few years ahead of DVD technology,you cannot loose with ANY Denon receiver.I will never own any other brand!KUDOS!



I hate giving any item a 5, but the 2805 is pretty close

Steven-Gulfport from Mississippi on 2/8/2005

Crutchfield Customer Review (What's this?)

I did a lot of research before deciding upon the Denon AVR-2805. Denon's solid reputation for a well engineered, reliable product was the factor in choosing Denon. The decision between the 2805 and 3805 was difficult.<BR><BR>The difference between the 2805 and 3805 boiled down to multiple room usage, and the Denon Link with HDCD/SACD direct input. Unless I was ready to spend big bucks for the DVD player, the Denon Link was not going to be a viable accessory. <BR><BR>The 2805 is a NICE receiver in all respects. The ultimate test for any receiver is how well the noise suppression circuits work. I have muted the input of the DVD player and cranked the volume setting to determine the background noise produced. It is not until I reach nearly the max volume setting that I am able to hear any background hiss. Remarkable achievement for a receiver in the under $2000 price range.<BR><BR>The 2805 is connected to Polk LSi 9's, LSiC, and LSi 7's, plus PSW10 sub. I watch a lot of movies with dialogue (Shrek, Titanic), and the 2805 is absolutely superb, handling the 4 ohm speakers with no problem. On movies with 5.1 material and deep bass (Gladiator, Saving Private Ryan) the 2805 is really solid. No clipping (and I violate the rules and set my main speakers to the large setting). Absolutely clean, smooth sound, even at ear bleed levels.<BR><BR>Musically, the 2805 is as good or better than the NAD separates that it just replaced. Lots of demanding rock and classical (Bach to U2). Never a problem, smooth sounding, even on solo violin and piano. <BR><BR>Draw backs to the receiver? Like all receivers the back connections are closely spaced.

Inputs And Outputs Notes


DDSC-Digital (Dynamic Discrete Surround Circuit): The Denon AVR-2805 is equipped with the latest technology in surround audio performance, DDSC-Digital, featuring Analog Devices Hammerhead SHARC 32-bit floating point DSP processor. 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.

Dolby Pro Logic IIx: Dolby Pro Logic IIx furthers the matrix decoding of Dolby Pro Logic II to decode audio signals recorded on two channels into up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel sources to be played in up to 7.1 channels. The mode can be selected according to the source. There are 3 Dolby Pro Logic IIx modes: Music, Cinema and Game. (The Game mode is for 2-channel sources only.)

Surround Modes: This receiver incorporates a wide variety of surround modes to bring you maximum enjoyment from your audio and video software. The surround modes include:

  • Dolby Digital Surround EX
  • Dolby Digital
  • Dolby Pro Logic II
  • Dolby Pro Logic IIx
    • Music
    • Cinema
    • Game (2-channel sources only)
  • DTS Digital Surround
  • DTS-ES Extended Surround
    • DTS-ES Discrete 6.1
    • DTS-ES Matrix 6.1
    • DTS Neo:6 Surround

    • Mono Movie
    • Video game
    • Matrix
    • 5CH/7CH Stereo

Personal Memory Plus: The receiver has a personal memorize function that automatically memorizes the surround modes and input modes selected for the different input sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled. The surround parameters, tone control settings, and playback level balance for the different output channels are memorized for each surround mode.

Audio Delay Setting: When watching a DVD or other video source, the picture on the monitor may seem delayed with respect to the sound. You can delay the sound from 0 to 200ms in order to synchronize the sound with the picture. The audio delay setting is stored separately for each input source.

Two-channel Music Modes: There are three 2-channel playback modes exclusively for music:

  • Pure Direct: plays back music with an extremely high level of sound quality. All the video-related circuits and the front panel display are turned off so that music signals are reproduced with high quality. When an analog mode is selected, the digital processing circuits are also turned off to achieve the highest purity.
  • Direct: audio signals bypass the tone control circuits, and are transmitted directly, resulting in good quality sound.
  • Stereo: allows you to adjust the tone to achieve the desired sound while watching video images.

AL24 Processing: The receiver includes Denon's renowned 24-bit ALPHA processing technology that reproduces digital signals in a waveform with the smoothness of analog signals. This technology thoroughly suppressesannoying quantization distortion and faithfully reproduces the delicate musical details of low-level signals. AL24 processing works in 2-channel Stereo, Direct, Pure Direct modes.

24-Bit, 192 kHz D/A Converters: The AVR-2805 uses highly accurate Analog Devices Digital-to-Analog converters, two for each channel, for a total of 16. The 192kHz sampling and 24-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

Auto Setup/Room EQ: The receiver is equipped with an Auto Setup and Room Equalization function, to achieve the most ideal sound field for your room. With the supplied DM-S305 microphone placed at the listening position, the 32-point DSP automatically and accurately analyzes, adjusts and sets the speaker configurations of your system. The receiver also analyzes and adjusts the frequency response of the speakers to the room with an 8-band parametric equalizer. You can also manually adjust the 8-band equalizer from -6dB to +6dB in 0.5dB steps at 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz and 8kHz.

Room EQ Memory: Once the Auto Setup has been performed, the receiver can memorize a maximum of 4 equalizing curves called "normal," "front," "flat," and "manual," allowing you to recall your favorite EQ curve without having to run Auto Setup each time. You can also "assign" an EQ curve for each surround mode, plus select the EQ to be on or off for the Pure Direct/Direct modes.

Subwoofer Crossover Frequency: You can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz, 200Hz or 250Hz.

Muting Level Adjustment: You can set the amount of attenuation for the audio muting circuit at -40dB or -20dB from the present volume level or totally mute the volume.

Dual Source/Dual Zone Capability:The AVR-2805 allows you to enjoy one audio/video program source in a second room while another source is playing in the main room. The Zone 2 output includes a composite video output and a variable stereo pre-amp output that can send a signal to an amplifier or a set of powered speakers located in another room. If the main room is not configured for 7.1-channel surround, the Power Amp Assign function allows you to assign the two Surround Back amplifier channels to Zone 2 to drive a pair of speakers, and still provide 5 discrete amplifier channels to drive all speakers in a 5.1-channel surround configuration. The volume of the Zone 2 output is variable, controlled by the receiver's remote control.

Video Up Conversion: The receiver's video transcoding technology converts composite and S-Video signals to component video signals and output to the monitor. This allows you to enjoy the highest picture quality from all video gear connected to the receiver. In addition, composite video signals are up converted to S-Video and S-Video signals are down converted to composite for connecting convenience.

HD Video Switching: The unit has three assignable component video inputs and a high-performance relay that is used to switch the signals. The switcher has an extended bandwidth range of up to 100 MHz, making it compatible with progressive DVD (480p) and HDTV formats (720p and 1080i).

Remote Control

RC-974 Remote Control: The AVR-2805 comes with a remote control which can operate the receiver as well as other remote control capable Denon components. In addition, the remote is pre-programmed with control signals for other brands of products, including cable boxes, CD players, TVs, Cassette decks, Laserdisc, DBS, VCRs, CD recorders, Minidiscs, DVD players and DVD recorders. The RC-974 is also a learning remote, and has illuminating source buttons and glow-in-the-dark volume and transport (Stop, Play, Pause, Rev, FFwd, etc) buttons.

System Call:The remote control is equipped with "System Call" (or macro) functions, allowing a series of remote control signals to be transmitted by pressing a single button. Up to 10 sequential signals can be stored in each of the 2 System Call buttons.

Inputs And Outputs Notes

Assignable Digital Inputs: The AVR-2805 features 5 optical digital (Toslink) inputs and 2 coaxial digital inputs. Each input can be assigned to any of the different input sources except Phono and Tuner. Optical Digital Inputs 3 and 4 also have corresponding Optical Digital outputs for use with a CD, MD or other digital recording device.

7.1 Multi-Channel Input: The AVR-2805 is equipped with a 7.1-channel input to accommodate present and future multi-channel formats. These inputs are rated up to 100kHz for high resolution audio sources such as SACD or DVD-Audio.

Speaker Terminals:All of the receiver's speaker terminals are binding posts. They are not 5-way binding posts because a plastic collar prevents their use with spade lugs and they are positioned too far apart to be used with dual banana plugs.

RS-232C Port:The AVR-2805 includes an RS-232C port for connection to external whole-house control systems from companies such as AMX, Crestron, and others, and provides a software/firmware upgrade pathway.

Room-to-Room Remote Jacks: The receiver has a mini-jack input for use with an optional Denon RC-616 IR re-transmitter. The adjacent room-to-room output is for future use.

12V Trigger Outputs: The AVR-2805 has a 2 mini-jack outputs to send a 12-Volt DC "turn-on" signal to another component that accepts a 12V trigger, such as a power amplifier. These trigger outputs can be assigned to the Main Zone, Zone 2 or Zone 3.

Front Panel Inputs: This unit features stereo audio, composite video and S-Video, and an optical digital input on the front panel for conveniently connecting a game console or camcorder. The input for the DM-S305 microphone is also located on the front panel. These inputs are covered by a removable panel.

Headphone Jack: The receiver has a standard 1/4" headphone jack on the front panel, positioned behind the fold-down panel.
