It's even got Dolby Pro Logic® IIx processing, which lets you turn stereo music, TV shows, and video games into enveloping 7.1-channel surround sound. The multichannel thrills will never end!

Denon's new Auto Setup takes the hassle out of speaker configuration. Just plug in the included microphone and place it in your favorite listening seat. The '2105 then uses a series of test tones to balance levels and fine-tune delay settings for every speaker in your home theater system. The result is incredibly easy and accurate speaker setup, custom-tailored to your specific room and speakers!

You'll also be able to enjoy 7.1 home theater surround in your main room while housemates listen to music in a second room, thanks to the '2105's dual-room/dual-source capability. You'll need a separate receiver or integrated amplifier for your second listening room — or, if you step to 5.1 audio in your main room, the '2105 can also power a pair of second-room speakers!

The AVR-2105 treats all of your digital sources right with ultra-precise 192kHz/24-bit digital-to-analog converters. And analog mode to bypass the tone controls and other processing for the cleanest possible sound.

This receiver offers plenty of digital and analog inputs for system-building, including a 7.1-channel preamp output for system expansion. Front-panel A/V and optical digital inputs offer quick, effortless hookup of a camcorder, game system, or portable audio player. Component video conversion greatly simplifies hookup to your TV and lets you preserve maximum video quality for all sources. The multibrand remote with glow-in-the-dark keys provides easy control of your entire system.

AVR-2105 WOW!!

James Talley from San Francisco, CA on 5/25/2005

Crutchfield Customer Review (What's this?)

This AV receiver really rocks. I used the component and digital inputs for the CD/DVD player, and I'm hearing musical notes that I wasn't hearing before with my old Technics Prologic receiver (1992)The clarity of the music and the video reproduction were awesome!! This receiver really fulls my room 15 X15 with incredible definition through all channels. Even if no audio or video are playing, there is absolute silence from my speakers. No hiss or hum (I was getting a 60hz hum with my old receiver when the volume was turned up by half and that included a mild hissing sound)With the AVR-2105, there is complete silence from my speakers, even when the volume is at max. My only problem with this receiver is that the speaker binding posts are way too close together. I use Monster speaker wire for my hookups and had to do some ingenius rewiring/cutting using this particular brand of speaker cable. I suggest to other users to use the banana plugs for the speaker wire hookup connections. Other than that, I'm very pleased with this receiver



Denon AVR-2105

dmesherb from Baltimore, Md on 5/19/2005

Excellent receiver and more than ample for the 17x14 family room. Using as a 5.1 w/ Zone 2 (outside). Connected phono (yes I still have a working one.), tape (yep one of them too.), CD, DVD, and VCR w/ no issue.<BR><BR>Cons are the standard. Need time w/ remote to get use to it. Stupid Audio/Video selection switch. With that many buttons, should be able to select device directly. The other con is closeness of speaker jacks. Needed needle-nose pliers to slip wire all the way thus jacks.

Crutchfield Customer Review (What's this?)

Another quality receiver by Denon. More than enough power to fill my 15'X 15'family room. 5/1 speaker configuration is enough for superiorsound and clarity. Radio reception great. Remote and unit are very user friendly. Pleased again. That's why this is my third Denon receiver.



Denon AVR-2105

Gregory from Buffalo, New York on 2/15/2005

Great Power, Great Sound. Ease of set up and fine tune adjustments,like speaker delay and ease of sound shaping make this a great sounding unit with power to spare. The purchase of this receiver was an upgrade from an older Denon AVR unit and I spent many hours trying to decide on what new receiver to purchase. After auto set up with on screen details and some minor adjustments I was more than sattisfied with my decision to purchase another Denon AVR unit. 100% happy with this AVR unit.

Inputs And Outputs Notes


Digital Signal Processing (DSP): The Denon AVR-2105 is equipped with a new high-resolution Analog Devices Hammerhead 32-bit floating 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.

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
    • Music
    • Cinema
    • Game
    • Dolby Pro Logic
  • 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
      • Neo:6 Cinema
      • Neo:6 Music
  • DTS 96/24
  • Denon Original Surround Modes (DSP)
    • Rock Arena
    • Jazz Club
    • Mono Movie
    • Video game
    • Matrix
    • 5CH/7CH Stereo

Personal Memory Plus: The receiver has a personal memorization 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. By inputting the distance between the listening position and each speaker, the proper amount of delay is applied to synchronize the sound with the picture. You can set the distance of each speaker between 0 and 15 feet in 1-foot increments.

Cinema EQ: The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for the overly bright sounding motion picture soundtracks. You can select this function when the front speakers sound too bright. This function only works in the Dolby Pro Logic IIx, Dolby Digital, DTS Surround, and DTS Neo:6 modes.

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

  • 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.

24-Bit, 192 kHz D/A Converters: The AVR-2105 uses highly accurate Analog Devices 24-bit, 192 kHz Digital-to-Analog converters on all 8 channels. 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: The receiver is equipped with a new 7.1-channel Auto Setup function to achieve the most ideal sound field for your room. With the supplied DM-S305 microphone placed at the listening position, the powerful new 32-bit floating point DSP automatically and accurately analyzes, adjusts, and sets the speaker configuration of the system. The microphone is a specially designed, high performance unit with a heavy duty base that suppresses vibrations for accurate analyzing.

Subwoofer Settings: When "Large" is set for the front speakers, and "Yes" is set for the subwoofer in the speaker setup, you can choose the following settings for the subwoofer channel:

  • Subwoofer Mode: You can select one of two modes:
    • LFE Normal: subwoofer plays the LFE channel signals (during playback of Dolby Digital and DTS signals) and the low frequency signal range of the channels set to "Small" in the speaker setup. Low frequencies for channels set to "Large" are played from those channels only.
    • LFE + Main: subwoofer simultaneously plays the low frequency signal range of the channels set to "Large" and the LFE channel signals. In this playback mode, the low frequency range expands more uniformly through the room.
  • Crossover Frequency: You can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz, 200Hz or 250Hz.

Dual Source/Dual Zone Capability: The AVR-2105 allows you to enjoy one source in your main listening room, while another source plays in a remote room. Depending on how you configure the receiver, using the dual zone capability of this receiver will require an amplifier and speakers, a set of powered speakers, or simply a set of non-powered speakers located in a remote location. If the receiver is set up for 7.1 surround operation, the Zone 2 RCA outputs act as fixed-level line outputs, and there are no Zone 2 amplified (speaker-level) outputs; in this configuration, the RCA line outputs must be connected to an amplifier or powered speakers equipped with a volume control. If the main room is configured for 5.1-channel surround, the Power Amp Assign function allows you to use the two Surround Back speaker outputs to power speakers in your remote listening room. When the Power Amp Assign function is active, the level of the Zone 2 speaker and preamp outputs can be controlled with the Zone 2 volume buttons on the remote.

Video Up Conversion: The receiver's video transcoding technology converts composite and S-Video signals to component video signals to 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-980 Remote Control: The AVR-2105 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.

Inputs And Outputs Notes

Assignable Digital Inputs: The AVR-2105 features 3 optical digital (Toslink) inputs and 1 coaxial digital input. Each input can be assigned to any of the different input sources except Phono, Tuner and V.Aux (front panel). There is also one Optical Digital outputs for use with a CD, MD or other digital recording device.

5.1 Multi-Channel External Input: The AVR-2105 is equipped with a 5.1-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. You can set the playback level of the analog input signal connected to the External Input terminal to +0dB, +5dB, +10dB or +15dB.

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.

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.

Front Panel (V.Aux) 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 for private listening. When headphones are plugged in, the receiver's speaker and preamp outputs are automatically turned off.
