AV receivers Denon

7.1 Ch, 6 Ohms, 1 kHz, 170 W, 24-bit / 192-kHz, HDCP, 18.5 kg, Silver 7 channel equal power output
7 channel equal power is a feature used in Denon Amplifiers with the means of connecting 7 speakers independantly which do not require separate power amps connected via the pre-outs. This feature compliments Dolby Digital EX and DTS ES sound modes. Allowing you to connect the second 'surround back' speaker, which compliments the surround back speaker initially there for 6.1, straight off the main amplifier without adding a power amplifier to support 7.1 surround formats. The amplifier has built in separate internal amplifiers to power each channel independently, this system ensures that the 6 major channels Front Left, Front Right, Center, Surround Left, Surround right, Surround Back left and Surround Back right. Thus allowing you to enjoy the same high power output, giving a balanced and truly high-impact surround-sound environment.

AL24 Processing Plus
Denon has further developed its proprietary AL24 Processiing, an analog waveform reproduction technology, to support the 192-kHz sampling frequency of DVD-Audio. This new technology, called AL24 Processing Plus, thoroughly suppresses quantization noise with D/A conversion of LPCM signals to reproduce the low-level signals with optimum clarity that brings out all the delicate nuances of the music. In high-end models, AL24 Processing Plus for all channels.

ALPHA Processing
ALPHA processing is the world's first technical formula for reproducing an analog waveform from the reproduction of 16-bit data in 20-bit quality. The ALPHA processer interpolates the digital data recorded on a CD and reproduces it in a waveform that is very close to the way these musical signals would look in a natural analog waveform.

Auto Setup and Auto Room EQ with Audyssey MultEQ XT
The Audyssey MultEQ XT allows room correction and calibration technology. During the Auto Set-Up mode, MultEQ XT automatically determines how many loudspeakers are connected, whether they are connected in phase and whether they are satellites or subwoofers. When it has processed this it then analyzes and calibrates speaker level, size, and distance. In addition, MultEQ XT detects the proper crossover point and determines correct frequency response for up to eight listener positions simultaneously. This is the first system to optimize and compensate the system for more than one listening location at the same time giving nearly every listener in the room a "sweet spot" no matter where they're sitting. Denon's implementation of MultEQ XT uses multiple Texas Instruments' Aureus DSP processors with high-end digital-to-analog converters. Both the Room EQ and Auto Set-Up features can be disabled if required.

Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, DTS, or other formats emphasizes high-frequency range due to a theater’s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range is too strong. Denon amplifiers feature a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II, and DTS surround modes.)

D.D.S.C. HD Digital
D.D.S.C.-HD for high-quality high definition Sound Reproduction: DDSC (Dynamic Discrete Surround Circuit)-HD (High Definition) Digital is a circuit configuration specially designed by Denon in which all elements of the surround processor are optimized through the use of selected high-performance discrete components, including separate A/D and D/A converters, with sophisticated HD DSP surround decoding.

DENON LINK
Connected via a shielded twisted pair (STP) RJ-45 fitted cable to a Denon Link-compliant A/V amplifier, the balanced signal transfer offers lower voltage than coaxial or unbalanced cables. Since DENON Link is far less susceptible to radiated noise, it ensures the highest level of signal transfer. The DENON Link interface is able to transfer high grade LPCM 24-bit, 192kHz, 2-channel and 96kHz, 24-bit, multi-channel digital output. Since Denon Digital 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.

Dolby Digital EX
In a movie theater, film soundtracks that have been encoded with Dolby Digital surround EX technology are able to reproduce an extra channel which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently available front left, front center, front right, surround right, surround left and subwoofer channels. The additional channel provides the opportunity for more detailed imaging behind the listener and brings more depth, spacious ambience and sound localization then ever before. Dolby Digital EX is not available in the system without surround back speaker(s).

Dolby Digital-Decoder
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ".1" channel, containing bass frequencies of up to 120Hz).

Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies - 22kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.

Dolby Pro Logic II
The Dolby Pro Logic ll decoder reproduces dynamic 5.1-channel surround sound from 2-channel sources such as TV, videos and CDs. Dolby Pro Logic ll uses matrix-decoding technology that has been dramatically improved over Pro Logic. With Pro Logic ll, for instance, the Surround channels are in stereo instead of just mono with Pro Logic, and playback covers the full frequency range instead of just up to 7kHz with Pro Logic. These improvements let you enjoy a wide variety of 2-channel sources with the exciting effects of 5.1-channel surround sound. In Dolby Pro Logic ll, there is a Movie mode (*1) that creates a sound field for movies, a Music mode that does the same for music, and a Pro Logic emulation feature that reproduces sound effects in the way that conventional Pro Logic does.

Dolby Pro Logic II Music: The music mode creates a rich and enveloping surround ambience delivered to the subwoofer, optimizing the visceral of planned rear effects. This mode can only be used with 2-channel audio sources.

Dolby Pro Logic II Cinema: The Cinema mode is optimized for movies or programs with Dolby Surround soundtracks. This mode is also appropriate for use with video game.

Dobly Pro Logic II Game: The game mode was implemented to ensure that the bass impact from pure surround effects are fully delivered to the subwoofer, optimizing the visceral of panned rear effects. This mode can only be used with 2-channel audio sources.

Dolby Pro Logic IIx
Dolby Pro Logic IIx is an extension of Dolby Pro Logic II technology. This highly sophisticated algorithm processes native stereo and 5.1 channel content to produce 6.1 or 7.1 output channels. And Dolby Pro Logic IIx is not available in the system without surround back speaker(s).

Dolby Pro Logic IIx Music: The music mode creates a rich and enveloping surround ambience delivered to the subwoofer, optimizing the visceral of planned rear effects. This mode can only be used with 2-channel audio sources.

Dolby Pro Logic IIx Cinema: The Cinema mode is optimized for movies or programs with Dolby Surround soundtracks. This mode is also appropriate for use with video game.

DTS 96/24
DTS 96/24 allows high-quality 5.1 channel sound playback with full-quality, full-motion video. DTS 96/24 allows both digital audio output and video output from your existing DVD player and is backward compatible with existing DTS decoders for normal DTS 5.1 playback. DTS 96/24 actually exceeds the resolution of most film soundtrack masters to date, and will initially apply mainly to high quality DTS music DVD discs.

DTS-Decoder
A data compression method developed by Digital Threater Systems that takes six channels of audio (5.1) and folds them into a single digital bitstream. This differs from Dolby Digital in that the data rate is a somewhat higher 1.4 Mbs, which represents a compression ratio of about 4 to 1.In order to take advantage of this DVD feature, a DTS decoder is required. DTS decoders are installed internally in Denon players and A/V recievers.

DTS-ES Discrete/Matrix 6.1
DTS-ES Extended Surround is a multi-channel digital signal format develpoed by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTS-ES greatly improves the 360 degree surround impression and space expression thanks to further expanded surround signals. This format has been used professionally in movie theaters since 1999.

In addition to the 5.1 surround channels, DTS-ES also offers the surround back channel for surround playback with a total of 6.1 channels. DTS-ES includes two signal formats with different surround signal recording methods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1.

DTS-ES Discrete 6.1
DTS-ES Discrete 6.1 is the newest recording format. With it, all 6.1 channels (including the SB channel) are recorded independently using a digital discrete system. The main feature of this format is that because the SL, SR and SB channels are fully independent, the sound can be designed with total freedom and it is possible to achieve a sense that the acoustic images are moving about freely among the background sounds surrounding the listener from 360 degrees. Though maximum performance is achieved when sound tracks recorded with this system are played using a DTS-ES decoder, when played with a conventional DTS decoder the SB channel signals are automatically
down-mixed to the SL and SR channels, so none of the signal components are lost.

DTS-ES Matrix 6.1
With this format, the additional SB channel signals undergo matrix encoding and are input to the SL and SR channels beforehand. Upon playback they are decoded to the SL, SR and SB channels. The performance of the encoder used at the time of recording can be fully matched using a high precision digital matrix decoder developed by DTS, thereby achieving surround sound more faithful to the producer’s sound design aims than with conventional 5.1- or 6.1-channel systems. In addition, the bit stream format is 100% compatible with conventional DTS signals, so the effect of the Matrix 6.1 format can be achieved even with 5.1-channel signal sources. Of course it is also possible to play DTS-ES Matrix 6.1 encoded sources with a DTS 5.1-channel decoder.

EL-Touch-Panel Remote Control
Electroluminescent display which is very similar to the technology employed by LCD backlights. Electroluminescence is a simply light (radiant energy) created by an electrical field that does not result in heat. On the Denon remote the luminous blue color of the buttons is merely the backlight being allowed through the insulating surface that covers the remote’s functions. Each function, or button, has its own parent EL area and the EL backlight is configured so as to allow different buttons to become lit when certain modes are engaged.

HDCD-Decoder
HDCD-encoded CDs are encoded with 20 bits of real musical information, as compared with 16 bits for all other CDs. HDCD overcomes the limitation of the 16-bit CD format by using a sophisticated system to encode the additional 4 bits onto the CD while remaining completely compatible with the existing CD format. HDCD provides more dynamic range, a more focused 3-D soundstage, and extremely natural vocal and musical timbre. With HDCD, you get the body, depth, and emotion of the original performance not a flat, digital imitation.

HDMI-output (HDCP)
HDMI (high definition multimedia interface), a new connector that bases itself on the DVI-HDCP model. HDMI supports uncompressed high definition video plus multi-channel audio in a single cable using a smaller connector that eliminates the need for multiple cables in home entertainment systems, simplifying installation and eliminating cross technology confusion. It transmits uncompressed digital video so that the picture maintains a high quality of color depth, brightness and contrast. It also supports Consumer Electronics Control (CEC) based on the AV.link protocol so it can be controlled with a universal remote that is used with multiple HDMI sources such as Denon DVD players. HDMI supports bi-directional coommunciation between devices, allowing DVD players to communicate with Plasma's, LCD screens and Projectors, as long as they are HDCP compatible.
The HDMI connection supports every uncompressed standard, enhanced and high definition video format ranging from 480I to 480P, 720P, 1080I and 1080P as well as existing PAL formats. It also has the bandwidth to support compressed audio formats such as Dolby Digital, Dolby Digital EX, DTS, DTS EX and uncompressed formats (PCM audio) up to eight channels, up to 192kHz, up to 24-bits.

High Definition Multimedia Interface(HDMI) and High Definition Content Protection (HDCP) is a copyright protection system installed on most Plasmas, LCD's and projectors consisting of a HDMI or DVI input. All Denon DVD players require HDCP compliant displays to be fully compatible. It prohibits the copying of copyrighted material, like onto a VCR or DVD-recorder.

Progressive Scan
Progressive scan works in the same manner as your computer monitor. It writes one full frame of video from left to right across the screen every 1/60 of a second. Since the entire image is drawn at one time--as opposed to an interlaced image where the even lines are drawn first, followed by the odd lines--a progressively scanned video image looks more stable than an interlaced one. Progressive scan also introduces fewer motion artifacts, such as jagged diagonal lines and movement in fine detail, into the picture.

Progressive-scan Denon DVD players will work with digital HDTVs and are not compatible with older analog sets, due to their higher horizontal-scanning frequency of 31.5kHz. One big feature that will be in any progressive-scan DVD player is 3:2 pull-down circuitry. This helps to differentiate between the 24fps (frames per second) frame rate of film and the 30fps frame rate of video. Bassically it smoothes out the picture and virtually eliminates jaggie artifacts.

Progressive-scan DVD players deliver much better pictures as they can read extra data tags on DVDs and the players can process the image digitally before they output the video signal in analog form. (Almost all home-theater DVD players can output only an analog signal.) If you feed an interlaced DVD signal to a digital HDTV, the TV's line doubler must convert the signal to digital before processing the image, and the TV doesn't have access to the extra data stored on the DVD. For this reason, a progressive-scan DVD player can deliver a sharper, cleaner picture.
