Denon has once again set the benchmark for surround sound receiver performance with its remarkable AVR-5805CI — the latest flagship in their impressive receiver line. The '5805CI offers exceptional power and flexibility, plus a host of advanced audio and video features that enhance the high-definition home theater experience.

Boasting an astounding 170-watt x 10-channel amplifier and exclusive THX processing, the '5805CI delivers spectacular surround sound from all your movies, music, and TV shows. Its computer networking compatibility lets you access the digital music library stored on your PC. And XM Satellite Radio fans will love the fact that this receiver is "XM Ready." Simply add an optional XM Mini-Tuner package and an XM subscription to listen to more than 170 XM Satellite Radio channels.

Superior picture quality from every video source
The '5805CI features some of the most advanced video switching capabilities you can find in a home theater receiver. It can accept as many as six high-definition digital video signals at resolutions up to 1080p via five HDMI jacks and one DVI input. This allows you to hook up plenty of hi-res sources such as an HD DVD or Blu-ray player, an HDTV tuner, or a high-end DVD player like Denon's DVD-5910CI, and easily switch among them.

The '5805CI can also upconvert analog video signals to 1080p using sophisticated Faroudja video scaling — an improvement over the basic analog-to-HDMI conversion found on many receivers. This type of video conversion ensures you'll enjoy the best possible picture quality from all of your video components, digital or analog. And it streamlines your system's video connections by allowing you to send all of your video sources to a compatible TV using a single cable.

Easy and accurate home theater setup
The AVR-5805CI boasts advanced automatic setup and room equalization adjustments developed by Audyssey Laboratories. This not only takes the hassle out of speaker configuration, but also makes superb home theater sound a breeze. Just plug in the included microphone and place it in up to eight seats in your home theater room. The '5805CI uses a series of test tones to balance speaker levels and fine-tune the delay and EQ settings for each speaker. The result is multichannel sound that's optimized across your entire listening area, with a "sweet spot" big enough for plenty of friends and family members. This receiver also detects and sets the appropriate crossover point for each speaker in your main room, achieving an ideal balance of sound between your subwoofer and your other speakers.

Enjoy different sources in 4 rooms simultaneously
The '5805CI not only delivers intense, dynamic home theater sound but also offers serious multi-room flexibility. You and your family can enjoy up to four different audio/video sources in four different rooms at the same time. Its 10 configurable amplifier channels let you power speakers in up to four rooms, with a huge variety of options:

  • 5.1 surround in main room with all channels bi-amplified
  • 5.1 surround in main room, 5.1 surround in 2nd room
  • 5.1 surround in main room, stereo in 2nd and 3rd rooms, mono in 4th room
  • 6.1 surround in main room, stereo in 2nd and 3rd rooms
  • 7.1 surround in main room, stereo in 2nd room, mono in 3rd room
  • 9.1 surround in main room, mono in 2nd room

Discrete circuit design and top-notch construction
Denon's DDSC-digital construction treats your audio to a series of scrupulously isolated, single-function circuit blocks. With digital-to-analog conversion, analog-to-digital conversion, and surround decoding each handled by its own dedicated block, every function is optimized, and so is your sound.

For stereo digital music sources in your main room, switch on Pure Direct mode — it uses four digital-to-analog converters per channel to deliver phenomenally detailed sound. Advanced Alpha 24 Processing, the latest version of Denon's acclaimed upsampling technology, enhances multichannel music sources with expanded dynamic range and frequency response. And Denon wraps it all up in the beefiest, most rock-solid chassis they've ever built. Make sure you've got an extra-sturdy A/V cabinet or reinforced shelving to house this 11"-tall, 97-pound powerhouse.

Signal Processing

Lucasfilm Home THX Ultra2 Certification: This unit has been built and tested to conform to the high standards of sound and build quality set by the THX Ultra2 Certification program. Home THX is the unique collaboration between Lucasfilm Ltd. and audio equipment manufacturers. THX Ultra2 certification provides a rigorous set of performance standards, along with proprietary surround sound post-processing technologies, designed to enhance the surround sound playback experience in the home theater. When the Home THX Cinema mode is on, the following THX post-processing is added:

  • Re-Equalization: The tonal balance of a film soundtrack tends to be excessively bright and harsh when played back over audio equipment in the home because film soundtracks are designed to be played back in large movie theaters using very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie soundtrack in a typical home environment.
  • Timbre Matching: The human ear changes our perception of a sound depending on the direction from which the sound is coming. In a movie theater, there is an array of surround speakers so that the surround information is all around you. In a home theater only two or four surround speakers are used. The Timbre Matching feature filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.
  • Adaptive Decorrelation: In a movie theater, a large number of surround speakers help create an enveloping surround sound experience, while in a home theater there are usually only two or four surround speakers. This can make the surround speakers sound like headphones that lack spaciousness. The surround sounds will also collapse into the closest speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time and phase relationship with respect to the others. This expands the listening position and creates the same spacious surround experience as in a movie theater.

THX Ultra2 Cinema Mode: The AVR-5805CI is equipped with THX Ultra2 Cinema mode that plays 5.1 channel movies using 8 speakers (7.1). The THX processing blends the surround and surround back speakers providing the optimal mix of ambient and directional surround sounds. DTS-ES and Dolby Digital EX 6.1 channel soundtracks are automatically detected and processed appropriately.

ASA (Advanced Speaker Array): ASA is a proprietary THX technology that processes the surround and surround back signals to provide the optimal surround experience. ASA is used in THX Ultra2 Cinema, THX Music Mode, and THX Games Mode.

THX Music Mode: THX Music mode can be used for playing 5.1 multi-channel music sources. In this mode THX processing is applied to the surround channels to provide a wide and stable rear soundstage.

THX Games Mode: Two channel stereo and multi channel, analog and digital signals are compatible with THX Games Mode. ASA is used to accurately place all game audio information, providing a full 360° playback environment. THX Games Mode is unique as it gives you a smooth transition of audio in all points of the surround field.

THX Surround EX: With the AVR-5805CI Dolby Digital EX soundtracks further undergo Home THX Cinema processing to achieve a THX Surround EX system. This mode gives you more detailed imaging behind you, allowing for 360-degree surround sound effects.

DTS-ES Extended Surround: This format greatly improves the 360° surround impression and space expression thanks to further expanded surround signals. This format has been used professionally in movie theaters since 1999. DTS-ES includes the Surround Back (SB) channel in addition to the existing 5.1 surround channels of front left, front right, center, surround left, surround right, and LFE, enabling surround playback from a total of 6.1 channels. Due to differences in surround signal recording methods, DTS-ES offers two formats:
  • DTS-ES Discrete 6.1: Discrete 6.1 utilizes the digital discrete method to record all 6.1 channels independently. Since the surround left, surround right, and surround back channels are fully independent, sound can be freely designed and sound images can move freely and rapidly amongst each other within a background sound that envelopes the room from all sides
  • DTS-ES Matrix 6.1: In the Matrix 6.1 format, the surround back channel is matrix encoded in advance to the surround left and surround right channels, and when a matrix decoder plays them back, they are decoded into separate surround left, surround right, and surround back channels

DTS Neo:6 Surround: Featuring the newest DTS matrix processing technology, the DTS Neo:6 function provides up to 6.1-channel surround sound from conventional stereo sources, and can be used with virtually any 2-channel stereo source, analog or digital. Two modes are provided:

  • Neo:6 Cinema: Optimized for surround encoded stereo movie soundtracks
  • Neo:6 Music: Optimized for superior surround sound with stereo music sources

DTS 96/24: The AVR-5805CI is compatible with sources recorded in DTS 96/24, a new multi-channel digital format. This new format can reproduce high-resolution, 5.1-channel audio on DTS-capable DVD players (those with DTS digital output), without the need for special players such as DVD-Audio or SACD. Some DVD-Audio discs will have a DTS 96/24 mix for compatibility with DVD-Video players.

Dolby Digital EX: Dolby Digital EX soundtracks have an additional surround channel signal matrix encoded into the standard surround channel signals of a Dolby Digital soundtrack. When a Dolby Digital EX soundtrack is decoded you will hear more detailed imaging behind you; this feature brings more depth, spacious ambience and sound localization to the home theater experience than ever before. Although Dolby Digital EX decoding produces the best results with soundtracks that have been recorded with Dolby Digital EX processing, the Dolby Digital EX decoding feature can be used, with varying results, with all 5.1 channel Dolby Digital, DTS or MPEG soundtracks.

Dolby Digital: Dolby Digital is the discrete multi-channel digital surround format developed by Dolby Laboratories consisting of 5.1 channels, front left, front right, center, surround left, surround right, and LFE (Low Frequency Effects or subwoofer, referred to as the .1 channel). Unlike the analog Dolby Pro Logic format, Dolby Digital's channels can contain full range sound information. Each channel is distinct from the others, allowing pinpoint imaging. Dolby Digital also offers tremendous dynamic range from the most powerful sound effects to the quietest passages, free from noise and distortion.

Dolby Pro Logic II: Pro Logic II is a Dolby Laboratories technology that produces surround sound from any stereo source, including CDs, VHS tapes, and TV programs. Like Dolby Digital, Dolby Pro Logic II has stereo surround output, giving you a more realistic surround sound experience. Another benefit of Pro Logic II over the original Pro Logic is better frequency response from the rear channels (full band width compared to Pro Logic's 7 kHz limitation). Unlike Dolby Digital, Dolby Pro Logic II allows you to enjoy a "5.1-like" (not discrete) presentation using any analog stereo source. Pro Logic II includes a Cinema mode, a Music mode, a Game mode (2-channel sources only), and Pro Logic mode; the Pro Logic mode decodes audio in the same manner as original Pro Logic.

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 channels. 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. Within these modes you can adjust the following settings.

  • Panorama: This setting extends the front stereo image to include the surround speakers for a more wraparound effect with side wall imaging. You can turn this setting On or Off.
  • Dimension: This setting gradually adjust the soundfield either towards the front or towards the rear of the room. The control can be set in 7 steps from 0 to 6.
  • Center Width: This setting adjusts the center image so it may be heard only from the center speaker, only from the left/right speakers as a phantom image or from all three front speakers to varying degrees. The setting can be set in 8 steps from 0 to 7.

Dolby Headphone: This receiver includes the new Dolby Headphone signal processing mode. Extended headphone listening can cause fatigue, because all of the sound resonates inside the head. Dolby Headphone replicates speaker playback in a room and places the sound at the front or the sides, outside the head, to achieve sound resembling movie or home theaters. The Dolby Headphone mode is effective for both stereo and multi-channel audio sources. There are three levels of effect: DH1--Reference room (small room with weak reverberations), DH2--Live room (slightly stronger reverberations than DH1), and DH3--Large room (offering a sense of distance and sound diffusion effects). In addition to Dolby Headphone playback, the AVR-5805 MK II can also output signals encoded in the Dolby Headphone mode from the recording output terminal to allow recording to another digital or analog recording device.

Surround Modes: In addition to those listed above, you can choose from the following modes:

  • Wide Screen: Achieve an atmosphere like that of a movie theater with a large screen, all signal sources are played in the 7.1-channel mode including Dolby Pro Logic and Dolby Digital 5.1-channel sources, effects simulating the multi-surround speakers of movie theaters are added to the surround channels
  • Super Stadium: For watching sports programs to achieve a sound as if you were in the stadium, provides the longest reverberation signals
  • Rock Arena: Gives the feeling of a live concert in an arena with reflected sounds coming from all directions
  • Jazz Club: Creates the sound field of a live house with a low ceiling and hard walls, gives jazz a very vivid realism
  • Classic Concert: Rich in reverberations like the sound of a concert hall
  • Mono Movie: Select this when watching monaural movies for a greater sense of expansion
  • Video Game: For video game sources
  • Matrix: Emphasizes the sense of expansion for music sources recorded in stereo
  • Virtual: Select this mode to enjoy a virtual surround field from the front two speakers
  • 5/6/7/8/9Ch Stereo: The surround (both sets) and surround back speakers all output two channel stereo, the in-phase component of the left and right channels is output to the center channel


10-Channel Power Amp: The AVR-5805CI has 10 discrete channels of amplification, each with 170 watts of output, which can be configured in numerous ways. Some examples include:

  • Dual 5.1-channel Discrete Zones
  • 5.1-channels in the Main Zone with all channels Bi-Amplified
  • 5.1-channels in the Main Zone, Stereo in Zones 2 and 3, and Mono in Zone 4
  • 6.1-channels in the Main Zone, Stereo in Zones 2 and 3
  • 7.1-channels in the Main Zone, Stereo in Zone 2 and Mono in Zone 3
  • 7.1-channels in the Main Zone with the Front L/C/R channels Bi-Amplified
  • 9.1-channels in the Main Zone, and Mono in Zone 2

New DDSC-Digital (Dynamic Discrete Surround Circuit): The New DDSC-Digital is a high-quality surround sound reproduction circuit, specially designed by Denon, to faithfully reproduce the original intent of content producers. The fully discrete design of the New DDSC-Digital in which high-performance ICs are used in independent blocks to form a single processor that reproduces surround sound, and the discrete design ensures that all channels are endowed with identical response and quality of sound.

192kHz/24-bit Digital-to-Analog Conversion: The latest high-accuracy 192kHz/24-bit D/A converter has been employed for the audio DAC. The AVR-5805CI has 8 of these D/A converters for 16 circuits, achieving differential drive for all 16 channels and digital-to-analog conversion with wide dynamic range at a high signal-to-noise ratio.

AL24 Processing: The AVR-5805CI includes Denon's renowned 24-bit AL24 processing technology that reproduces digital signals in a waveform with the smoothness of analog signals. This technology thoroughly suppresses annoying quantization distortion and faithfully reproduces the delicate musical details of low-level signals. This version of AL24 processing supports 192 kHz sampling frequency and 5.1 channel signals including the Zone 2 multi-channel outputs.

Video Digital to Analog Converter: Denon uses high speed 216MHz/12-bit video DACs to achieve greater fidelity in composite, S-Video, and component video signals, both standard and high definition. Additionally noise shaped video (NSV) technology improves video S/N for greater signal linearity.

DCDi: DCDi is a specialized processing system developed by Faroudja that involves advanced algorithms to remove the jagged edges that appear when standard interlace video is viewed on progressive scan displays. DCDi converts standard interlaced signals into progressive signals in order to eliminate the stair casing effect that conventional up-converters can introduce to diagonal edges.

Scaler: When the video signal is converted to component video or HDMI/DVI the resolution can be scaled as well. The output can be set to 480p, 1080i, or 720p. In the case of the HDMI/DVI output the scaler can be set to 1080p.

Digital Video Switching: This unit has 5 HDMI inputs, a DVI-D input, an HDMI monitor output, and a DVI-D monitor output. The HDMI and DVI-D monitor outputs can only be used one at a time, not simultaneously. You can output both audio and video from the HDMI output when the input signal is coming through one of the HDMI inputs. You can output only video from the HDMI output when the input signal comes through the DVI-D input. Only video can be fed from the DVI-D output, regardless of the input. The HDMI and DVI-D connections support components with HDCP copyright protection.

Component Video Switching: In addition to composite and S-Video switching, this unit can switch between component video sources. There are 6 component video inputs and 3 component video outputs (including a Zone 2 output); each input and output has gold-plated RCA or BNC jacks labeled "Y", "Pb/Cb" and "Pr/Cr". This feature allows you to connect, and switch between, high resolution video sources equipped with component video outputs. High performance relays provide wideband component video bandwidth (>100 MHz), compatible with progressive DVD (480p), as well as HDTV formats (720p, 1080i). All component video outputs are active simultaneously so 3 HDTVs can be fed a signal at the same time.

Video Conversion: The AVR-5805CI 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.

  • Composite video: Can be converted to S-Video, component video, or HDMI/DVI
  • S-Video: Can be converted to Composite video, component video, or HDMI/DVI
  • Component video: Can be converted to composite video, S-Video, or HDMI/DVI

Time Base Corrector (TBC): The AVR-5805CI uses a TBC in converting composite and S-Video signals to component video to suppress jitter in the video signal during playback.

Dual Surround Speaker Mode: The AVR-5805CI provides outputs for two different sets of surround speakers, allowing you the flexibility to choose the speaker design and placement to optimize both movie soundtracks and music with no compromise. Use the amplifier assign function to select which set of speakers is powered for a given input.

Multi-Zone Output: The AVR-5805CI provides Multi-Zone outputs that let you send different sources to multiple zones (different rooms). The four zones (main room, Zone 2, Zone 3, and Zone 4) can play four different sources at any given time. Zone 2 has line level 5.1-channel RCA audio, composite video, S-Video and component video outputs. Zone 3 has line level stereo RCA audio (fixed or variable volume), composite video, and S-Video outputs. Zone 4 has line level stereo RCA audio outputs (fixed or variable volume). The receiver's Power Amplifier Assign function also lets you assign amplifier channels to drive up to 5 speakers in Zone 2, and one or two speakers to Zone 3 and/or Zone 4, while leaving the remaining amplifier channels to drive speakers in the main room.

Bi-Amp Connections: The AVR-5805CI Amp Assign mode allows you to power bi-amp-capable speaker with two amplifier channels, up to a total of 5 bi-amplified speakers in a system using a 10 of the receiver's amplifier channels.

On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The OSD is sent through all monitor outputs (composite video, S-video, component video, and HDMI).

Multi-Channel Inputs: The AVR-5805CI is equipped with two multi-channel inputs to accommodate present and future multi-channel formats, such as DVD-Audio, SACD, HD-DVD, and Blu-ray. One input has 9.1 channels (Front, Center, Surround-A, Surround Back, Surround-B, Subwoofer) and the other has 5.1 channels.

HDCD (High Definition Compatible Digital) Playback: HDCD is an encoding/decoding technology that greatly reduces the distortion that occurs during digital recording while maintaining compatibility with the conventional CD format, thus expanding the dynamic range and achieving higher resolution. HDCD encoded CDs are identified automatically to select the optimum digital processing.

RDS (Radio Data System) Tuner: RDS is a broadcasting service which allows FM radio stations to send additional information along with the regular audio signal.

XM Satellite Radio Ready: With the XM Mini Tuner and Mini Tuner Home Dock, you can listen to XM satellite on the Denon AVR-5805CI. You will have over 150 commercial-free channels of music, news, sports, comedy, talk, and entertainment to choose from - all in digital quality. The plug on the back of the receiver is a proprietary plug, so the only antenna that will work with this unit is included with the Mini Tuner Home Dock. A subscription to XM Radio is also required.

Note: A 50' extension is available for the Mini Tuner Home Dock if the supplied cable is too short.

Custom Integration: The AVR-5805CI 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.

Personal Memory Plus: The Personal Memory Plus function automatically memorizes the surround modes and input modes selected for the different input sources. When an input source is selected, the modes stored in memory for that source are automatically recalled.

Pure Direct Mode: In addition to surround sound playback, the AVR-5805CI lets you enjoy pure 2-channel stereo sound through its Pure Direct mode. In Pure Direct mode, power to the video circuitry, the front panel display, and any other unnecessary circuitry is turned off so all available effort if spent reproducing 2-channel audio. Four DACs are used to maximize sound quality.

Manual Bass Management and Speaker Setup: Various settings are available to ensure that small speakers do not receive full-range signals and to tell the receiver where to send signals.

  • Front Speakers: The front speaker size may be set to Large (full range) or Small (high pass crossover engaged, the crossover point is individually adjustable for each set of channels and has the same setting options as the subwoofer crossover)
  • Center Speaker: If you selected Large as the front speaker size, the center speaker may be set to Large, Small or None, if you selected Small as the front speaker size, the center speaker may be set to Small or None
  • Subwoofer: Select Yes or No
  • Surround Speakers A: If you selected Large as the front speaker size, the surround speakers A may be set to Large, Small or None, if you selected Small as the front speaker size, the surround speakers A may be set to Small or None. Note: If you have selected None as the surround speakers A size, the surround speakers B and surround back speakers are automatically set to None
  • Surround Speakers B: If you selected Large as the front speaker size, the surround speakers B may be set to Large, Small or None, if you selected Small as the front speaker size, the surround speakers B may be set to Small or None
  • Surround Back Speakers: If you selected Large as the size for the front speakers and either the surround speakers A or surround speakers B, the surround back speakers may be set to Large, Small or None. If you have selected Small as the front speaker size or if both the surround A and surround B are set to small, the surround back speakers may be set to Small or None. Once the surround back speaker size is set, you may set the number of surround back speakers, 1 or 2
  • Subwoofer Crossover Frequency: The frequency of the low pass filter on the subwoofer output can be set to a fixed (80Hz THX setting) or variable output according to the speaker's bass playback ability (selectable between 40, 60, 80, 90, 100, 110, 120, 150, 200, and 250 Hz). In addition to these settings, if you are using a THX Ultra2 certified subwoofer, you can use the Boundary Gain Compensation. The Boundary Gain Compensation allows the subwoofer to receive very low frequencies (20-55Hz). If the bass seems too strong, the compensation can be set to on to cut the lower frequencies
  • Delay Time: The delay time (as a function of distance from speaker to listening position) for each channel can be adjusted from 0 to 60 feet in 0.1 or 1 foot increments
  • Test Tone: The volume level of each channel is adjusted independently using the test tone

Audyssey MultEQ XT: The AVR-5805CI's Audyssey MultEQ XT function is designed to optimize the sound quality at each listening position in the room. The DM-S305 microphone (included, free, with purchase of the Denon AVR-5805CI, from Crutchfield) 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 six positions should be measured, one of which is the main position which is given more weight in the calculations. Like the manual speaker setup, Audyssey adjusts each channel's crossover frequency, delay time, and output level. The AVR-5805CI Room EQ function offers three correction curves.

  • Audyssey: This feature adjusts the frequency response of all speakers to correct the effect of room acoustics.
  • Front: This setting adjusts the characteristics of each speaker to the characterizes of the front speakers.
  • Flat: This functions makes the frequency response for all the speakers flat. This is suitable for mult-channel music reproduction from discrete music sources such as Dolby Digital 5.1, DTS, DVD-Audio and Super Audio CD.

Audyssey MultEQ XT Pro Ready: The Audyssey calibration system can now be upgraded to the Pro system for up to 32 listening position calibration points when used with the optional PC software (sold separately) from Audyssey.

Manual Equalizer: An eq curve can be manually set for each channel (front left, front right, etc/surround back is adjusted as a single channel). The adjustment range runs from +6 to -20 dB in 0.5 dB steps at nine frequencies, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8kHz, and 16 kHz.

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 Pro Logic (including PL II and PL IIx), Dolby Digital, DTS Surround, DTS Neo:6, and Wide Screen modes.

D.COMP (Dynamic Range Compression): 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, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). This only works when playing program sources recorded in Dolby Digital or DTS. You can select one of the four settings: "OFF", "LOW", "MID" (middle), or "HI" (high).

Dialogue Normalization: The dialogue normalization function is activated automatically when playing Dolby Digital program sources. Dialogue normalization is a basic function of Dolby Digital, which automatically normalizes the dialog level (standard level) of the signals that are recorded at different levels for different program sources, such as DVD, DTV and other future formats that will use Dolby Digital.

LFE Setting: This function sets the level of the LFE (Low Frequency Effect) sounds included in the source when playing programs sources recorded in Dolby Digital, DTS, DVD-Audio or Super-Audio CD. You can make adjustments from - 10 to 0 dB.

Night Mode: When listening to your movies or music at night or a lower volumes, the Night Mode improves your listening enjoyment. This mode only works for Dolby Digital recorded material.

Input Name: The name displayed on the receiver's front panel and on a connected TV monitor can be customized with a new name up to 8 characters.

Input Function Level: If the volume of one source is higher (or lower) than the others it can be adjusted to match. Each input has an input function level which is adjustable from -12dB to +12dB in 1dB increments.

Audio Delay: The audio signal can be delayed, from 0-200ms, to match the video signal.

Last Function Memory: This unit is equipped with a last function memory, which stores the input and output setting conditions as they were immediately before the power was switched off.

Setup Lock: This feature sets whether or not to lock the system setup settings so that they cannot be accidentally changed.

Back-Up Memory: The unit is also equipped with a back-up memory. This function provides approximately one week of memory storage when the main unit's power switch is off and with the power cord disconnected.

Remote Control

Multi-brand/Learning Remote: The RC-1036 has controls for an entire home theater system on its EL touch panel screen and hard-keypad. You can navigate and make selections by touching the screen directly. When a component is selected (receiver, DVD Player, etc) the keys on the electroluminescent panel change and are specific to that component. The remote also features a hard-keypad for volume, channel and on-screen display operation. The remote also features a numerical keypad as well (0-9, +10). In addition to being pre-programmed to control many brands of audio/video source components and TVs, this remote also has learning capability, allowing it to be customized for any installation.

LCD Display: The remote's 1.5" x 3" EL touch-panelscreen's brightness can be adjusted in 5 steps to accommodate your room's lighting. The EL screen's lighting time can be set to 5, 10, 15, 20 or 25 seconds. You can press any button on the remote to activate the electorluminescent screen.

Hard Keys: Hard keys have been provided on the main unit for frequently-used operations, such as volume, channel selection, cursor and select, and power.

System Call: Up to 3 System Call settings (macros) with up to 32 sequentially-issued commands can be stored. The System Call programs you have stored can be easily be checked on the LCD panel.

Inputs and Outputs Notes

Speaker Terminals: The AVR-5805CI's 10 speaker outputs feature gold-plated binding post terminals. These terminals can accept bare wire, pin connectors, and single banana plugs. A plastic collar surround the terminal post prevents the use of spade lugs, and the positive and negative terminals are spaced too far apart for dual banana plugs. The speaker outputs can be configured to virtually any channel or zone you wish. They are labeled on the back of the receiver as Left 1 through Left 5 and Right 1 through Right 5.

Assignable Digital Inputs: The 6 optical and 6 coaxial digital inputs are assigned to individual input sources (Example: Optical 1 assigned to CD, Optical 2 assigned to DVD, etc). Optical inputs 3, 4, and 5 are equipped with an optical digital output jack that can be used for digital recording between a digital audio source and a digital audio recorder.

Front Panel Inputs: Behind the flip-down panel, the receiver features the following jacks:

  • Headphone: Standard 1/4" gold-plated headphone jack
  • V.Aux Input: Gold-plated stereo RCA jacks, RCA composite video jack, S-video jack
  • Digital Input: Toslink optical input (#6, can be assigned to any input except the Tuner or Phono)
  • Microphone Input: 3.5mm (1/8") mini-jack for connecting the DMS-305 microphone (microphone included, free, with purchase of the Denon AVR-5805CI, from Crutchfield)

Multi-Channel Inputs: The AVR-5805CI is equipped with two multi-channel input sections to accommodate present and future multi-channel formats, such as DVD-Audio, SACD, HD-DVD, and Blu-ray. The Ext.In-1 input has 9.1 channels (Front, Center, Surround-A, Surround Back, Surround-B, Subwoofer) and the other has 5.1 channels.

Denon Link 3rd Edition: This RJ-45 jack allows the connection of a Denon DVD player (with Denon Link output) for ultra-clean digital transfer. The Denon Link interface enables the transfer of high-grade linear PCM 96kHz/24-bit 6-channel audio or 192kHz/24-bit 2-channel audio via a shielded twisted pair cable. (If the 192kHz/24-bit source is copyright protected, the DVD player may convert the digital output to a 48kHz/24-bit signal). Since Denon Link uses low-voltage differential signaling (LVDS), transfer capabilities of greater than 1.2 Gbps at a differential voltage of approximately 0.3 Vpp are possible. The signal transfer is balanced and voltage is lower than coaxial or unbalanced cables so Denon Link is far less susceptible to radiated noise, ensuring the highest level of signal transfer. In most cases Denon Link enables Denon components to transfer DVD-Audio signals digitally. (The digital transfer of SACD signals will be available in the future after a firmware upgrade)

RS-232C Port: The AVR-5805CI includes an RS-232C port for connection to external whole-house control systems from companies such as AMX, Crestron, and others. The port also provides a software/firmware upgrade pathway.

Ethernet: The Ethernet port is used to integrate with your home network.

IEEE 1394: The back panel has two IEEE 1394 ports. IEEE 1394, also known as "i.LINK", is a high speed digital interface that may be used for plug and play connection of compatible digital components. Once connected, each i.Link port is assigned to an input.

Component Video Jacks: This receiver has two types of component video jacks. Component Video Inputs 1 through 5 have three RCA jacks, while Component Video Input 6 features BNC jacks. Component Video Monitor Output 1 also has BNC jacks, while Output 2 and Zone 2 Output have RCA jacks.

HDMI/DVI-D Inputs/Outputs: This unit has 5 HDMI and 1 DVI-D inputs, all assignable to different input sources. There is one HDMI and one DVI-D output, however, only one can be used at a time. All of the HDMI and DVI-D jacks support HDCP copyright protection.

Preamp Outputs: There are preamp outputs for every channel, and for every zone. They are grouped as follows:

  • 9.1-channel: Front L&R, Center, Surround A L&R, Surround Back L&R, Surround B L&R, and Subwoofer
  • Zone 2 Output: Front L&R, Center, Surround L&R, Subwoofer
  • Zones: Stereo outputs for Zone 2, Zone 3 and Zone 4

Assignable AC Outlets: The three AC outlets are switched, so they will turn on and off as the main power to the receiver is turned on and off. Each can be activated by choice of input source or surround sound mode by each zone, to activate specific external components as necessary.

12 Volt Trigger Outputs: Four different 12-volt trigger outputs allow the automatic activation of externally controlled devices, such as motorized drop-down screens, motorized drapery, motorized screen masking systems, or amplifiers. These 3.5mm (1/8") mini-jack trigger outputs can be assigned to a different zone.

Room-To-Room Remote Control Jack: The input jack of the Room-to-Room Remote allows you to connect the optional Denon RC-616 Infrared Re-transmitter. The RC-616 is connected to the RC-617 Infrared Sensor in another room, allowing you to control the receiver using an infrared remote control from another room.

XM: This proprietary terminal allows you to connect an optional XM Connect-and-Play satellite antenna.
