Our take on the Denon AVR-2311CI

Unlike other receivers, the '2311CI can pass high-definition 3D video signals from a 3D Blu-ray player to your 3D TV — no mean feat, since that's nearly twice the bandwidth of a 1080p HD signal. It's a smart choice for anyone interested in 3D at home, whether you're planning to put together a 3D TV system now, or a few years down the road.

Cutting-edge technology for stellar performance

The AVR-2311 has definitely earned its spot in Denon's high-end "CI" line. Solid Denon build quality means you'll get a reliably stunning picture and consistently detailed, enveloping surround sound. And thoughtful touches make this receiver easier to set up and use.

The '2311CI is ready for 3D — are you?

Unlike other receivers, the '2311CI can pass high-definition 3D video signals from a 3D Blu-ray player to your 3D TV — no mean feat, since that's nearly twice the bandwidth of a 1080p HD signal. It's a smart choice for anyone interested in 3D at home, whether you're planning to put together a 3D TV system now, or a few years down the road.

Super sharp video and a cleaner setup

The '2311CI can take each and every video signal you give it — including standard-definition signals from sources like your Wii™ or DVD player — and send everything to your TV over a single HDMI cable. This minimizes cable clutter, and also makes your system easier to use since you won't have to switch inputs on your TV. Better yet, the '2311CI can upconvert all your sources to 1080p to better match your TV's high-def screen.

The '2311CI loves music, too

Quite a few receivers have a USB input, but the '2311's front-panel USB is special. It has dedicated iPod support — you simply connect your iPod or iPhone using its supplied USB cable, and press Play on the receiver's remote. More goodness: Instead of the sound quality being limited by the iPod's made-for-earbuds audio circuitry, digital signals are sent straight to the Denon's high-quality DACs, so all your favorite tunes will sound better. Or plug in a USB flash memory drive, or hard disk drive loaded with your music. Switch on Denon's Compressed Audio Restorer mode to flesh out the sound of your MP3 collection. Adding an optional Denon iPod dock lets you enjoy photos and videos too. There's even beautiful music in the air. The built-in HD Radio™ tuner lets you tune in to HD Radio stations in your area, so you can enjoy clear digital broadcasts.

Smart features for easier setup and use

Like a lot of receivers these days, the '2311CI features automatic speaker calibration. But unlike some auto calibration systems, this receiver's Audyssey MultEQ® system can calibrate for up to six different positions in the room — a big plus if you like to have a few people over for movie night or Sunday football. Everyone will hear impressively accurate, convincing surround sound, not just the person in the "sweet spot."

Auto calibration is really easy to use — just plug in the included microphone and let the '2311CI do the rest. Watch the video below to get a better sense for how MultEQ can improve the sound in your room.

The '2311CI also features user-friendly on-screen menus that are easy to read and navigate. And three "Quick Select" buttons on the front panel and remote let you save settings for your favorite activities. So, for example, when you press Quick Select 1, the receiver could switch to the Blu-ray player input and adjust the volume to your preferred movie-watching level.

    Crutchfield Customer Review (What's this?)

    This is my third Denon receiver and does everything I need it to do. I love the Audyssey Auto Setup. I have a 7.1 system and it never sounded as good as it does now. The AVR-2311CI passes video signals, including 3D flawlessly. I have all of my sources connected through the Denon receiver including Bluray DVD player, a DVD/VHS recorder, a Directv satellite receiver, a CD player, and Nintendo Wii game console. I would recommend the AVR-2311CI to anyone looking for an outstanding receiver. I also recommend purchasing it from Crutchfield. They are the best, and you can't beat the support you get from them. Their Advisers can answer any technical questions you have before and after purchase.

    best one only thing the manual is terrible.




    Dr. Joshua from Perryville, MD on 2/2/2011

    Crutchfield Customer Review (What's this?)

    Excellent product! Intelligently designed, easy set-up, and superb quality with room to grow. I appreciate the attention to detail that Denon has provided; i.e. lowering the volume when switching from sources, Sat/Cbl to Blu-ray etc. Excellent owner's manual which throughly covers all features. I tried several different methods of speaker configurations/adjustments and was most pleased with the Audyssey sound equalization set-up--it takes out the guess work of sound adjustments in oddly shaped rooms. Bottom line: very pleased and highly recommended.



    Great Receiver!

    alookman1 from Plano, TX on 12/22/2010

    This is my first Denon product, and as reviews say about AVR-1911 that Denon AVRs produces music well, and I can second that. My other options were Onkyo 708, Pioneer 1120 and Yamaha 667. All are great units but Denon AVR-2311CI excels at sound reproduction and it also excels at vido processing as well. My GUI works even with component hookup, not possible with Onkyo or others. My only complaint is the price. Last year's models are also much better deals and only lack 1.4 for 3D and no USB upfront.



    Great receiver

    AlexG from Austin, TX on 9/29/2010

    Crutchfield Customer Review (What's this?)

    This receiver sounds great for all inputs, switches video flawlessly, upgrades the SD content admirably, and was easy enough to install. I'm a committed Crutchfield customer and will continue to be so.

    Audio Features

    7-Channel Amplifier: The Denon AVR-2311CI features a 7-channel, equal power, discrete amplifier. Each channel is rated at 105 watts RMS. The seven amplifier channels built into the receiver are typically used for 7.1 channel surround in the main room, but there are various amplifier configurations to accommodate your home theater setup:

    • Normal: The AVR-2311CI is designed to be used as a 7.1ch surround sound receiver with front left/right, center-channel, surround left/right, and surround back left/right channels along with a preamp subwoofer output.
    • Zone2: The surround back channel amplifier can also be assigned to power stereo speakers in Zone2.
    • Bi-Amp: You can also configure the amplifier for front bi-amp operation to achieve a higher-quality 2-channel sound by connecting the receiver's front and surround back channels to your main front speakers.
    • 2-Channel: A different set of stereo speakers can be powered for dedicated (Direct) stereo listening.
    • Front B: A second set of front speakers can be powered by the surround back amplifier.
    • Front Height: To enjoy Dolby Pro Logic IIz you can reassign the power amp from the two surround back channels to the two front height channels for better front effects.

    Minimum Signal Path Design: The simple & straight design concept has been thoroughly implemented in the signal paths to contribute to clean audio and video playback. Signal paths are as short as possible to keep signal degradation in the audio and video circuitry to a minimum.

    Direct Mechanical Ground Construction: Vibration-resistant construction has been used to suppress the adverse influences of vibration on sound quality. The power transformers, a source of vibration, have been securely mounted on the high rigid bottom chassis. Direct mounting of cast-iron feet to the radiator in near proximity to each other serves to suppress mutual vibration with the power transformers and other sources of vibration.

    Audyssey: This receiver is equipped with an Auto Setup and Room Equalization function to achieve the most ideal sound field for your room. The AVR-2311's Audyssey MultEQ function is designed to optimize the sound quality at each listening position in the room. The included DM-A409 microphone is used to measure test tones at each listening position (up to six positions including the main position). This measured data is then analyzed using a program to improve acoustic characteristics in the listening area; the main position is given more weight in the calculations. Audyssey EQ offers the following options:

    • MultEQ: The MultEQ function offers the following adjustments:
      • 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 Byp. L/R: optimizes all speakers except front left and right
      • Audyssey Flat: optimize frequency response of all speakers to flat
      • Manual: adjusts the tonal quality for each speaker individually using the manual equalizer settings; adjust from -20 to +6 dB at 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz
      • Off: turns equalizer off
    • 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.
    • Dynamic Volume: 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 clearly heard. 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.

    Note: You can also setup your speaker system manually using the receiver. You can adjust speaker configuration (large/small/none), bass setting (LFE/LFE+Main), low-pass crossover (80/90/100/110/120/150/200/250Hz), speaker distance (0-60'), channel level (-12 to +12dB), and high-pass crossover frequency (40/60/80/90/100/110/120/150/200/250Hz)

    Surround Modes: This receiver incorporates a wide variety of surround modes to bring you maximum enjoyment from your audio and video software. The unit can be set to store the most recently selected surround mode for each input, so it is automatically activated each time the particular input is chosen. The surround modes include:

    • Dolby Digital: Dolby Digital is a 5.1 multi-channel digital surround format.
    • Dolby Digital EX: Dolby Digital EX is a 6.1 multi-channel digital surround format.

      • Virtual: enjoy surround effects using only the front speakers or headphones
      • Multi Channel Stereo: enjoy stereo sound from all speakers
    • Stereo: This is the mode for playing in 2-channel stereo; bass and treble can be adjusted and sound is output from the front left and right speakers, along with a connected subwoofer.
    • Direct: In this mode the audio signal is played in its original form, without any surround or tone processing.
    • Pure Direct: Like in Direct Mode, the audio signal is played in its original form, without any surround or tone processing. The display and analog video circuitry are also turned off to minimize the possibility of any noise being added to the signal.

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

    • 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.
    • 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 TrueHD.
    • D.Comp: Like DRC, but used with Dolby Digital and DTS sources.
    • LFE: This setting adjusts the low-frequency effects level (LFE); adjust from -10 to 0 dB.
    • Center Width: This function assigns the center channel signal to the front left and right channels for wider sound; select from 0 to 7. This function only works in the Dolby Pro Logic II Music and PL IIx Music modes.
    • Center Image: This function assigns a center channel signal to the front left and right channels for wider sound; adjust from 0.0 to 1.0. This function only works in the DTS Neo:6 Music mode.
    • Panorama: This feature assigns front left and right signals to surround channels for wider sound, you can turn this feature On or Off. This function only works in the Dolby Pro Logic II Music and PL IIx Music modes.
    • Dimension: This settings shifts the sound image to the front or rear to adjust playback balance; select from 0 to 6. This function only works in the Dolby Pro Logic II Music and PL IIx Music modes.
    • Delay Time: This feature adjusts the delay time (0-300ms) to control the sound stage size. In this menu the delay time is only adjusted for the Matrix mode.
    • Effect Level: This function adjusts the effect signal level from 1 to 15 when using specific Denon Original Surround Modes.
    • 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.
    • AFDM: Detects the source's surround back channel signal and sets the optimum surround mode automatically.
    • SB CH Out: This setting selects the playback mode for the surround back channels; there are separate settings for multi-channel and 2-channel sources.
    • Subwoofer: Turn the sub on/off.

    Multi-Zone/Multi-Source: Denon's Multi-Zone/Multi-Source function lets you select a different audio source for listening in a second location of your home. The AVR-2311CI features a Main Zone (audio and video) and Zone 2 (audio only). The Main Zone offers 7.1-channel playback of your audio/video gear in your main entertainment room. Zone 2 allows stereo audio playback of another source connected to the receiver in another room of your home via left/right RCA audio or speaker level outputs.

    Note: Zone 2 features 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-2311CI to power speakers in a second room of your home, the main zone is restricted to 5.1-channels. When using the receiver's preamp output terminals for the second room you need an additional amplifier to power those speakers and the main Zone of the receiver remains 7.1-channel.

    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.

    Tone Settings: You can independently adjust the system's overall Bass and Treble settings from -6 to +6 dB. You can also fade the sound from front to rear or vice-versa. Separate tone controls are available for the Zone2 outputs.

    Restorer:This function restores compressed audio signals to pre-compression form, correcting the sense of bass and treble volume to obtain a richer sounding playback; select 64, 96, or HQ based on the compression setting of the source material.

    Auto Lip Sync (Audio Delay): This feature automatically compensates for the timing shift between the audio and video of the receiver. If needed, the audio signal can be manually delayed to match the video signal; adjust from 0-200ms.

    Volume Setting:You can set a maximum volume level of 0, -10, or -20 dB to limit the receiver's total volume output. You can also specify a turn-on volume, from -80 to +18dB or Last (whatever the volume setting when the receiver was turned off).

    Muting Level Adjustment: 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).

    Assignable Digital Inputs: The AVR-2311CI features 2 optical digital (Toslink) inputs and 2 coaxial digital inputs. Each input can be assigned to any of the different input sources except Tuner. Optical Digital Input 2 also has a corresponding Optical Digital output for use with a CD, MD or other digital recording device.

    Binding Post 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.

    Personal Memory Plus: For each input, the receiver automatically memorizes the settings for input mode, surround mode, HDMI output mode, MultEQ, Dynamic EQ, Dynamic Volume, audio delay, etc. When the input source is switched, the settings last used for that source are automatically recalled. The surround parameters, tone control settings, and playback levels for the different output channels are memorized for each surround mode.

    Sleep Timer: This function allows you to automatically set the power to standby after a predetermined amount of time has passed; set the sleep timer up to 120 minutes in 10 minute increments.

    Video Features

    HDMI ver. 1.4a: This unit has six HDMI version 1.4a inputs and one HDMI version 1.4a output. The HDMI inputs are assignable to different input sources. They support HDCP copyright protection and are compatible with 3D signals, ARC (Audio Return Channel), Deep Color, xvYCC technology, Auto Lipsync, and HDMI control.

    Audio Return Channel (ARC): If the connected TV has HDMI version 1.4 and supports ARC, the audio signal can be transferred from the TV (when its internal tuner is used) to the AVR-2311CI through the HDMI cable, so a second cable isn't needed.

    3D: The AVR-2311CI will pass the 3D signal when connected to a 3D source (3D Blu-ray player, 3D cable box, etc) and a 3D TV.

    High-Bit i/p Converter and Scaler: The AVR-2311CI is equipped with a flexible video switching system that converts incoming video signals so only one video connection is required from the receiver to the TV. The 480i/480p (SD-quality) video signals of DVD programs and other materials input through receiver are scaled to 1080p signals, and output through the unit's HDMI monitor port to your HDTV. The converter and scaler can be turned off independently if you prefer. The scaler can also be applied to just analog input signals, or analog and HDMI. The converter works as follows:

    • Composite Video: converted to component video and HDMI
    • S-Video: converted to composite video, component video, and HDMI
    • Component Video: converted to HDMI

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

    Component Video Inputs/Outputs: The receiver features 2 component video inputs and 1 component video output. The component video inputs are assignable to different sources.

    On-Screen Display (OSD) With GUI Menus: An OSD with GUI menus can be displayed on your television for easy system setup. The OSD and GUI menus are sent through the receiver's HDMI and component video monitor outputs.

    Picture Adjustments: The receiver allows you to make the following picture adjustments to incoming video - Contrast, Brightness, Chroma Level, Hue, DNR (Digital Noise Reduction), and Enhancer (Sharpness).

    Video Select Function: You can switch the video input source on the receiver while listening to a different audio signal.

    Dimmer: The receiver features 4 display settings; Bright, Dim, Dark and Off.

    Tuner Functions

    HD Radio Tuner: The AVR-2311CI features a built-in HD AM/FM tuner. HD radio stations offer higher sound quality than conventional FM/AM broadcasts. HD FM stations sound as great as CD quality while HD AM sounds a rich as analog FM stereo. It is also possible to receive data services and select broadcasts from among up to eight multicast programs. In addition, the AVR-2311CI receives standard analog AM/FM broadcasts. You can store up to 56 radio stations presets (8 stations each in 7 separate banks). You can name each preset with an 8 character ID.

    USB/iPod Functions

    USB Terminal: A USB memory device can be connected to the USB type-A terminal located on the front panel, allowing you to play music files through the receiver. Compatible formats include MP3 (32-320kbps), WMA (48-192kbps), and AAC (16-320kbps).

    iPod Compatibility: Using a USB to iPod Dock cable plugged into the front panel USB port, music can be played directly from an iPod, bypassing the iPod's D/A converter. The iPod is controlled by the receiver's remote; text and elapsed time are displayed on the connected video monitor. Video and still photos (as well as music) can be played from an iPod using an optionalASD-11RK iPod dock. Using the dock cable to connect directly, iPod compatibility is as follows (as of July 2010):

    Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the device and your iPod/iPhone to regain functionality. If this doesn't work, you may need to revert to the older software version or wait until an newer software update is available.
