Our take on the Denon AVR-3808CI

Outstanding home theater performance is a sure bet with the AVR-3808CI. Denon packed an impressive array of advanced features into this receiver's rock-solid chassis, including PC networking, multi-room audio/video, flexible HDMI switching, and advanced auto setup. They also included built-in decoding for the latest surround sound formats, including Dolby® TrueHD and DTS-HD™ Master Audio — two high-resolution surround sound formats available with some Blu-ray players and discs.

Superior picture quality from every video source
Home theater owners with multiple high-def sources will appreciate this receiver's video switching capabilities. Four 1080p-compatible HDMI inputs let you connect your high-res video components and switch easily between them. Analog-to-HDMI conversion lets you send all of your video sources to an HDMI-capable TV using a single digital cable — this streamlines video switching and preserves maximum picture quality for each source. Plus you get sophisticated digital video upconversion that can upgrade any non-HD video source to an HDMI digital signal with resolution up to 1080p, to more closely match the capabilities of your HDTV.

Precision auto setup tailors sound to your room
Denon also included Audyssey MultEQ® XT, a sophisticated auto-calibration system that helps you get the most accurate home theater sound possible. The '3808CI uses the included microphone to analyze sound from up to six different listening positions, then automatically adjusts level, equalization, and delay settings for each of your speakers. You get precise response across a wide listening area instead of just a single "sweet spot," so everyone in the room can enjoy precisely balanced home theater sound.

PC music and other digital entertainment options
The '3808CI's Ethernet port lets you connect to your wired home computer network to access music files stored on a PC and listen to Internet Radio stations via your broadband connection. Front- and rear-panel USB ports let you plug in a compatible MP3 player, hard disk drive, or USB flash drive loaded with your favorite tunes.

Multi-room flexibility and more
This receiver's three-room/three-source output lets you enjoy a surround sound movie in your main room while a housemate watches a different video source in a second room, and another housemate listens to stereo music in a third. A handy learning/multibrand touchscreen remote makes it easy to control all of the components in your system. And a new and improved on-screen interface makes it a snap to operate the '3808CI using your TV screen.

Very nice unit upgrade from my Avr 635

Carrie from Buffalo, New York on 5/26/2009

Crutchfield Customer Review (What's this?)

I purchased this unit AVR3808CI as an upgrade to my AVR635 about a month ago and must say I am very pleased with it. I purchased it along with the DVD2500BTCI (Blu-ray transport only) and also am very pleased with it. The unit does take sometime to set-up and a lot of experimenting with the settings and the GUI for the set-up. The manual is not very helpful it is more like a guide but if you are purchasing this kind of unit it must be because you know your gear, and are not looking for the regular run of the mill Home Theater in a box type set-up. The setup is up to you and the knowledge of your gear. If something does not sound right check your other components. I had not put both video and audio through one unit until this one I tried with my H/K and was not happy with it but this unit handles both extremely well. I have several sources hooked up to the unit and must say you better know your other components settings because this unit will handle them differently both audio and video settings long set-up in the end it all turned out very well. I run a 7.1 setup using an Infinity Beta 50 system with two Infinity SW12 subs. In conclusion if you are not a tweak freak this unit may not be for you, but if you want to spend the time to make everything work this unit is probably the best bang for your money and handles both video and audio extremely well. I highly recommend this unit to anyone looking at an alternative to separates. Feature packed receiver.



Denon has a good product here

Dirk from Jonesboro, Arkansas on 3/29/2009

Crutchfield Customer Review (What's this?)

First off, I steped up to this unit from a Denon 3803. Second, I still haven't had alot of time to play with this AVR yet. With that said, lets start off with the first impression....a little step down from build quality of the 3803. I never liked the silver face of my 3803, but the feel and overall look of the 3808 seems cheaper. Around back, the connections are plentiful and cover almost all your bases. Denon still needs to put a way to control the AM/FM tuner from the front panel. Alot of people complain about the manual. I must admit it is bad, but if you stick with it you can get it. Having lived with the 3803 made some of Denon's quirks easier to understand (the manual to it was more of a book and not bunch of grids and page references) but some ways the 3803 handled were totally different than the 3808. The GUI is pretty, and makes the control of the unit akin to operating a computer. It is somewhat combersome at times, but not too much. The HDMI is slow to handshake from time to time, althogh I think this is just part of HDMI and not tied to the Denon. I have never used mulitzone output before, but I am thinking of doing it. You just have to realize that higher end components using HDMI and component connections will not be able to be utilized. The only things I would have added (and think Denon could have easily) would be HD-Radio, RDS, and a tape monitor loop.



I love Denon - but this unit is a train wreck

Terry from Illinois on 3/7/2009

Crutchfield Customer Review (What's this?)

As noted by nearly most every reviewer, even those with positive impressions of the 3808CI, the GUI will have you pulling out your hair within minutes. The user manual provides little in the area of support for this awkward system. The remote was cut from the same cloth as the GUI. During un-boxing, I almost accidentally threw out the set up mic because it's made out of light, cheap plastic and weighs almost nothing in its' box. In the same spirit I couldn't help but notice a flimsy unattractive quality to the knobs and faceplate of the unit. Heads up to PS3 owners. Even hooked up correctly, you will not get any visual indication that you are decoding HD sound tracks. The PS3 has no ability to output raw HD soundtracks for your 3808 to recognize, only decoded PCM. As reported by at least three other owners on a well posted AV forum, my front left and right full range speakers sounded as if someone had sucked all low frequency information from them when playing music. The only way to fix it was to run in Pure Direct mode. I can only guess why this happened - possibly erroneous Audyssey measurements, but at this point I was far too disappointed with my purchase to further troubleshoot the issue. I simply could not reconcile myself to the inept workings of either the Denon remote or its' GUI. Denon really belly-flopped on this one. Thanks to Crutchfield for return support.



Bite the Bullet..Do it.

Randy from Houston, Tx on 2/6/2009

Crutchfield Customer Review (What's this?)

Originally, just wanted a big screen TV. Then thought, maybe just a little surround sound. But wait, what formats would it support? What would I need? How should I route cables? If sound went to TV and then back to stereo, what about audio/video sync delays? Would the remote work with my other equipment? Could my wife operate it?....Aaarrrggggg!! So, after reading about 8 different Home theater user manuals in their entirety, I decided on this one. One HDMI cable from 3808 to new TV. Satellite, BRay, DVD, feed into 3808. No need to worry about what to do with sound. Only one device controls sound and video. On screen display is absolutely worth the extra several hundred dollars. Also, remote control is programmable with each key being able to "learn" from other remotes as well. Using my old Denon Stereo System to power my BOSE 901's as the sub-woofer.. Seems I can have my cake and eat it too. Only wish remote control provided was wireless.



No HDMI output for video select or multi-zone

Joe from Cleveland, OH on 1/10/2009

Denon always makes a good product and this is no exception. It seems, though, that they keep missing on the full use of HDMI. You can not output HDMI sources to zone 2 or 3, and while this in and of itself is no big deal, it gets worse when you want to select an HDMI source as the video output and listen to another source and can't do that either. For example I have my PS3 connected via HDMI. I have my ipod connected to the front a/v jack via a mini jack to RCA cable(allows volume control with ipod and receiver). When I have a party I would like to put my memory card from my camera in my PS3, select that for the video output and select my ipod for the audio output. This can not be done. I have to disconnect the HDMI from the receiver and connect it to the TV, OR I have to out and by the PS3 component cable. Yamaha doesn't have this problem. You would think that as top-of-the-line Denon claims to be they'd get these features figured out. What a disappointment. Just shows you need to read the ENTIRE manual before you even purchase.



Superb Performance! Worth the price!

Ram from Michigan on 1/3/2009

Crutchfield Customer Review (What's this?)

I bought this from Crutchfield almost a year ago and matched it with a pair or Polk RTi10s. I upgraded from a 13 year old JVC. What can I say? I am simply astounded the receiver's performance! My experience: Digital music: The convenience to play music off of USB sticks or off of a UPnP media server (I use MediaTomb) is great. I have hooked this receiver to the internet and the ability to listen to internet radio (and update firmware) without a computer is a plus as well. I cannot speak for iPod as I do not use it. The built in restorer makes the compressed MP3s/flacs sound nicer. I typically tend to use Direct Stereo mode, but the surround modes for audio are also good. Movies: Have only watched movies with Dolby/DTS tracks and they are precise. I don't know how Dolby True HD, DTS-HD sound. HDMI upconversion difference over a direct component video hookup is barely perceptible on a 52" screen. The receiver is loaded with features and that becomes a double edged sword. The manual and remote do not do justice to this fine receiver. The web interface, although very basic, is probably the easiest way to set up this receiver. But, Denon really dropped the ball on the web interface. It would have been really easy to provide useful hyperlinks to provide detailed help to various options. If you are willing to put up with a little annoyances setting this receiver up and reading through the manuals, you will reap the rewards with exceptional audio quality!



Best in class

rtc from Raleigh, NC on 8/15/2008

Crutchfield Customer Review (What's this?)

I've had my eye on this unit for a while now and finally picked it up when a fat commission check came in. The unit is pretty straight forward except for setting up dual zones. I have 2 outdoor speakers on the deck and 5.1 in the living room. The trick was having the surround mode in 7 channel (other surrond modes didn't work). The Amp Assign needs to be set to ZONE2 and speakers connected to Surround Back L/R. Use the Zone 2 feature on the remote to turn it on/off and adjust the volume. The media PC has to be connected to the DVR input if your sound source is being supplied by the HDMI cable. The on screen access for the IPod dock is really nice. To bad you can't access to IPod videos from that interface (you have to switch to IPod control and select it on your IPod). With the unit having the ability to get updates from the internet maybe someday this will be fixed. I would recommend picking up some 3-foot HMDI cables to keep everything neat at the back of the stereo cabinet.




dgtlmn from Augusta, Ga on 7/18/2008

Well, I went from the 3806 to the 3808ci, and I must say it's like putting on a new pair of shoes, familiar shoes that is. The remotes nearly the same so I didn't have to go through any trouble setting it up. thanks Denon for the new user interface it's so intuitive to setup i didn't even try the mike setup yet, just jumped right in so to speak. The onscreen menu's are so easy to setup, don't worry if you're a novice it's easy to get going and the sound oh the sound from movies to mp3's WOW! Oh I put the 3806 in my bedroom of course no trauma eh! Oh I considered the Yamaha RXV863, the Denon 2808CI, but got a last minute Awesome deal on this baby i still can't believe it! And Crutchfield great company to deal with maybe the best! As far as cons iI don't have any at all!!!!! Even if I did the 3808's performance outweighs anything as the British would say it's a great piece of kit! I'd read also of a lot of people having problems setting up the unit or that manual gave them fits really forget the manual and just make your connections the onscreen user interface will help the rest of the way, and if you get into a jam you can always back out of the menu. Truly a great machine well worth the investment and I love the ease of connecting to the web for firmware updates, very well thought out!



Getting what you paid for!

Gil from Rohnert Park, CA on 5/13/2008

I knew it was time for an upgrade and so had to do a lot of homework before picking my next purchase that would not cost me as much as filling a full tank of gas in California. I read the reviews & the features & specs on, thanks for a great source for finding information by the way, and decided that the Denon AVR-3808CI was going to be my next baby. I have my cable box, CD Player, HD DVD and Blu-ray player all going into the receiver and it sounds simply awesome. With the power sub that I have, it shakes the house, God, I love it, scares the heck out of my little kid. Still the manual is junk and really not helpful, but other than that, could not go wrong w/this piece of machinary. Also purchased the Logitech Harmony 1000 so my wife could watch TV or Hi-Def movies w/out pulling her hair out, she really has great hair too. So, if you are looking to do a surround sound the right way the first time, this Denon would be a great start. This is just a fantastic receiver (minus the manual) w/tons of features and for the price, could not get a better bang for your buck!!



Best experience in my life

chris from Lantana, Florida on 3/4/2008

Crutchfield Customer Review (What's this?)

This is by far the most incredible sound in both video and audio I have ever heard besides my 5308. This receiver is worth every penny and the great help and service from Crutchfield came with it. Every question and concern was addressed by Crutchfield without hesitation. Mated this with the Denon 2500 Bluray player and WOW is all I have to say.



Denon AVR-3808CI

EL Guero from Santa Fe, NM on 2/22/2008

After using it for about a week, I must say that the high-quality and versatility of this receiver are amazing. Also amazing is the terribly-written manual and mediocre remote controls. If you are serious about spending the time to play around and experiment and learn by brute-force tenacity, you will be rewarded. A properly-written manual that explains the how's and why's would go a long way to making the power of this device accessible to those with less patience and a less technical bent. The main I selected Denon over comparable brands is the multi-zone support. You really have to read the small-print because all of the offerings have limitations, some very severe such as inability of other brands to play digital inputs in zones other than the main zone. This is a big deal for me and I'm glad I went with Denon. The reason I selected this model over the 2808 is the networking, especially Internet Radio. So far I'm extremely pleased with this receiver.



Exceeded High Expectations

Ron from Tennessee on 2/18/2008

Crutchfield Customer Review (What's this?)

Outstanding AVR--pure and simple. Denon website instructions on firmware update process are easy to follow. Firmware update installed flawlessly. Automatic speaker setup worked equally well. Impressive capability. Software identified 6.1 speaker setup that was a problem with the initial version and that the firmware update fixed. Graphic on-screen interface is excellent and most useful. Within a few minutes the menu felt natural, and the remote is useful and easy to use with a little practice. Sound is exceptional, and the AVR display graphics are terrific. I have all AV components connected via HDMI--Comcast digital/HDTV box, Apple TV, Sony DVD, and Sony HDTV. The HDMI switching and upscaling appears to work exceptionally well. The video upscaling via HDMI has exceeded my expectations. I have inputs of 480p, 720p, and 1080i--all upscale to 1080p with no problem. I have experienced no noticeable problems with upscaling 1080i to 1080p, even with fast moving sports or movie scenes. I am not an audiophile or a videophile, but I have been able to use the 3808CI effectively. Bottom line--outstanding experience with this marvelous technology.




THE ONE from ST.LOUIS, MO. on 2/7/2008




Neat Receiver if you can figure it out!

Rudy from Rochester, NY on 2/1/2008

Crutchfield Customer Review (What's this?)

I'm using this receiver to control all my video and other audio components through ONE HDMI cable out to my wall mounted Panasonic Plasma. During the first two weeks, I came very close to repacking it and sending it back! However, after taking the time to figure it out, this is a very versatile and feature-packed receiver that won't become outdated anytime soon. The ugly: The user manual is just plain awful! Everything is in tables with very little in descriptions. Many button functions do not correspond to what is on the remotes. The multi-zone feature makes the remote confusing at times when it has to scroll through each zone for a particular component. The not-so-bad: The upconverting seems to work well, particularly on non-wide screen DVDs. The GUI on-screen is pretty useful, once you figure out how to navigate through it! I updated the firmware, but it takes about an hour to do. The good: once hooked up to your network, you can setup up and control the deck from Internet Explorer - a nice feature when I'm traveling and my wife can't figure out how to turn everything on. The preset internet radio stations are fantastic - who needs XM? The deck switches between each source easily. After two weeks, today was the first day I felt like I had made a good choice. If you very limited experience with audio/video equipment, you will be very intimidated by this receiver!



Way too complicated

stepha14 from Philadelphia PA on 12/16/2007

Crutchfield Customer Review (What's this?)

I bought this Denon because a friend told us "Denon is the best". I made a big mistake, this thing is a major pain, not only to set up, but to operate on a day to day basis. TWO remotes?? Like I don't have enough remotes already. As for the "instruction manual", you might as well use it for kindling, because it doesn't make any sense - looks like it was written by someone with absolutely no grasp of the English language. I seriously want to return it and get something else. For the amount of money this thing costs, it ought to be able to set itself up, and the controls should be straightforward! I was expecting something more along the lines of plug & play, not this aggrevating nonsense.



Denon AVR-3808CI

Daniel from Philadelphia, PA on 9/23/2007

I bought this receiver about a month ago.<BR>I had read different reviews here on Crutchfield but also went on the web to see what some of the major concerns on Denon receivers were.<BR>Denon manuals and the LCD remote control were the most mentioned issues, but no one appeared to have had any problems with the actual receivers themselves.<BR>While I was waiting for the receiver to come from Crutchfield, took about 3 days, I went on Denon USA and downloaded the manual (which is also available from Crutchfield) and just went over the setup part to get an idea of how their manuals were written.<BR><BR> It was pretty straightforward, so by the time the receiver came, it only took about an hour to connect all the wires and set up the Audessey Laboratories MultEQ XT six-point auto setup and room calibration system for a basic setup. Connect the Microphone included and pick out at least 6 spots where you want the optimum sound field to be and follow the automatic on-screen instruction and you will be good to go.<BR><BR>I use a 5 speaker Mirage OmnisatSat v2 speakers with the Mirage 10" sub woofer and the sound was incredibly clean and very natural sounding. I spent the next hours testing the different sound formats. Vivaldi , The four seasons in a DTS format and a live DVD performance by Sade and the landing at Omaha beach in Saving Private Ryan as well as the failed Bank robbery in the movie Heat and finally some rock music to hear high guitar pitches.<BR>All sounding incredible and made me want to go through my entire DVD collection as there were sounds and effects that I had never heard before.<BR><BR>I am the owner of a receiver far more advanced that I probably



Denon AVR-3808CI Impressions

Phil from Saint Louis on 9/21/2007

Crutchfield Customer Review (What's this?)

This is a very impressive piece of equipment and thanks to the on screen graphical interface is very easy to set up and control. I now have all audio and video routed through this receiver for the following components .. with room to spare.<BR><BR>Charter Set Top Box - Component<BR>Toshiba HD-XA2 - HDMI 1.3<BR>XBox 360 - Component<BR>Playstation 3 - HDMI 1.3<BR>Sony RDR-VS500 - Component<BR>OPDV971H - Audio Only (DVI to HDMI w/o DHCP was a no go.)<BR><BR>Driving a set of JBL CS6100 Surround Sound speakers with excellent results .. greate separation and zero distortion even when you crank it. All digital audio is also being output via Toslink to drive a set of Sony MDR-DS6000 wireless digital surround headphones (for late at night).<BR><BR>The real bonus is the HQV upscaling for all sources sending less than a 1080p signal. Faroudja upscaler does a great job especially with SDTV broadcasts, much better than the cable box or my Samsung HL-S5088W. All my component sources are being scaled up to 1080p with the added bonus that these signals are output on one HDMI connection. Makes bouncing between units a breeze since it all goes to one input on the HDTV.<BR><BR>Highly recommend this unit, especially if you have a growing number of HDMI devices or just want a single point of control. Logitech Harmony will be next on my list.

Inputs and Outputs Notes


7-Channel Equal Power Amplifier: The Denon AVR-3808CI features a 7-channel equal power, discrete amplifier. The amplifier is rated at 130 watts x 7-channels RMS.

AL24 Processing Plus: Denon has further developed its propriety AL24 Processing to support the 192 kHz sampling frequency of DVD-Audio. AL24 Processing Plus thoroughly suppresses quantization noise associated with D/A conversion of LPCM signals to reproduce the low-level signals with optimum clarity that will bring out all the nuances of the music. AL24 Processing Plus is applied to not only the front left and right channels, but also the surround left and right, center and subwoofer channels.

24-Bit, 192 kHz D/A Converters: The AVR-3808CI uses highly accurate Burr Brown PCM-1791 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.

DDSC HD-Digital (Dynamic Discrete Surround Circuit): The Denon AVR-3808CI is equipped with the latest technology in surround audio performance, DDSC HD-Digital, featuring dual Analog Devices Hammerhead SHARC 32-bit floating point DSP processors. 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.

Custom Integration: The AVR-3808CI carries the "CI" stamp, which is Denon's certification to custom installers that the receiver has advanced connectivity and control features often required for custom home integration and theater applications using premium control systems. These features include a RS232C jack for use with whole house control systems, remote in/out IR command control, and assignable +12-volt triggers.

Video Up-Conversion Powered With DCDi By Faroudja: The AVR-3808CI is equipped with a flexible video switching system that converts video signals in an effort to only require one video connection from receiver to TV. The video switching system features a Directional Correlation De-interlacing (DCDi) special video processor developed by Faroudja that involves advanced algorithms to remove the jagged edges that appear when standard interlaced video is viewed on progressive scan displays. DCDi converts standard interlaced signals into progressive scan signals in order to eliminate the stair-casing effect that conventional up-converters can introduce to diagonal edges. Unlike most other conversion circuits, this receiver will convert analog signals from composite video, S-Video, and component video to HDMI up to 1080p.

  • Composite Video: can be converted to S-Video, component video, or HDMI
  • S-Video: can be converted to composite video, component video, or HDMI
  • Component Video: can be converted to composite video, S-Video, or HDMI (480i signals only when down converting)

Note: Video signals input as HDMI must be output via HDMI.

Noise Shaped Video (NSV): The NSV precision video feature works in the digital domain to reduce noise in the video signal frequency band in order to enhance video signal linearity, provide accurate signal representations, and enhance the picture quality. Noise shaping techniques can be combined with dynamic element matching techniques in order to reduce the matching requirements of DAC elements by converting the analog mismatch into  and out of band noise. This approach of dynamic element matching and noise shaping has been shown to allow the use of sigma delta modulation at video data rates. NSV can achieve ultimate precision with 12-bit fidelity in both digital-to-analog and analog-to-digital domains.

HDCD Decoding: The AVR-3808CI automatically detects and decodes the digital bitstream from a CD that has been encoded through the special High Definition Compatible Digital (HDCD) process. HDCD discs use 20-bit encoding and other proprietary processing to provide the ultimate in CD listening.

  • 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

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.

Auto Setup:The receiver is equipped with an Auto Setup and Room Equalization function, to achieve the most ideal sound field for your room. The AVR-3808ci's Audyssey MultiEQ XT function is designed to optimize the sound quality at each listening position in the room. The included DM-A405 microphone is used to measure test tones at each listening position. This measured data is then analyzed using a program to improve acoustic characteristics in the listening area. For best results at least 8 positions should be measured, including a main position. The main position is given more weight in the calculations. The Audyssey function adjusts the following measurements automatically: Speaker Configuration, Distance, Channel Level, Crossover Frequency, and Room EQ.

Room EQ: The Room EQ function offers the following adjustments:

  • Audyssey: Adjusts the frequency response of all speakers to correct the effects of room acoustics.
  • Audyssey Byp. L/R: Optimizes frequency response of speakers except front speakers to match room acoustics.
  • Flat: frequency response of all speakers are flat.
  • Manual EQ: This feature adjusts the tonal quality for each speaker using the receiver's built-in graphic equalizer. You can select -20 to +6 dB for the following frequencies for each speaker - 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2khz, 4kHz, 8kHz, and 16kHz.
  • Off: Turns equalizer off.

Subwoofer Control: You can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz, 90Hz, 100Hz, 110Hz, 120Hz, 150Hz, 200Hz or 250Hz. You can also select the subwoofer output level between 0, 5, 10 or 15 dB.

Amplifier Assign: There are seven amplifier channels built into the receiver. These channels are typically used for 7.1 channel surround in the main room, but the amplifier assign function gives you the option of configuring the system differently if you prefer. The amplifier features four different amplifier assignment configurations.

Bi-Amp: Four of the seven amplifier channels can be used to bi-amp the front speakers, leaving three to power other channels.

Dual Surround Speaker Mode: The AVR-3808CI provides the ability to connect two different sets of surround speakers, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise. If you play one pair of surround speakers at a time (Surround A or B), the minimum impedance of the connected speakers is 6 ohms. If you play both pairs of speakers simultaneously (Surround A + B), the minimum impedance of the connected speakers is 8 ohms.

Multi Zone/Multi Source Operation:Denon's Multi-Zone/Multi-Source function lets you select different audio/video sources for listening and viewing in different locations of your home. The AVR-3808CI features a Main Zone (Zone 1), Audio/Video Zone (Zone 2) and Audio Only Zone (Zone 3). The Main Zone 1 contains 7.1-channel playback of your audio/video gear in your main entertainment room. The Audio/Video Zone 2 allows stereo audio and video playback of another AV source connected to the receiver in another room of your home via left/right RCA audio or speaker terminal output connections and a composite video connector. Audio Only Zone 3 allows you to play a stereo audio source connected to the receiver in a 3rd room of your house via left/right RCA audio or speaker terminal output connections.

Note: Zone 2 and Zone 3 feature either a preamp-output or speaker terminal output so you can use this amp or a separate amp to power speakers in another room. When using the AVR-3808CI to power speakers in a second room of your home, the main zone is restricted to 5.1-channel at the same time. Also, when using the AVR-3808CI to power speakers in a second and third room of your home at the same time, the main zone remains 5.1 channels, but the 2nd and 3rd Zone speakers are mono. When using the receiver's preamp output terminals for the second and third room you need an additional amplifier in each room to power those speakers and the main Zone of the receiver remains 7.1-channel.
