AL24 Processing Plus, thoroughlysuppresses quantization noise associated with D/Aconversion of LPCM signals to reproduce the low-level signals with optimum clarity that will bring outall the delicate nuances of the music.Equipped foe not only front left and right channelsbut also for the surround left and right, center andsubwoofer channels.Audyssey Dynamic Surround Expansion™(A-DSX)Realistic reproduction of sound relies on theability of audio systems to match human hearingperformance. Three key requirements are: (1)frequency response, (2) dynamic range, and (3)accurate spatial reproduction. The requirements forfrequency response have already been surpassedwith sampling rates that exceed human hearing.The dynamic range limits of human perceptionhave also been met with current digital audiosystems operating capable of signal to noise ratiosthat approach 120 dB. Accurate spatial soundrendering, however, has not yet reached the limitsof perception as human perception relies on thecombination of sounds arriving from many moredirections than what 5.1-channel surround soundsystems provide. Audyssey DSX technology wasdeveloped to overcome the spatial sound renderinglimitations faced by 5.1-channel surround soundformats.The ITU 5.1-channel channel standard recommendsthree front loudspeakers and two rear loudspeakers.The Left (L) and Right (R) front loudspeakers shouldbe placed at ±30° relative to the central listeningposition. The Center (C) loudspeaker should be at0° and the surround loudspeakers (SL, SR) shouldbe placed between 100° and 120°. All loudspeakersmust be equidistant from the center listeningposition or compensated with time delay if thatis not possible. A separate low-frequency effects(LFE) channel is used to reproduce additional basscontent from the subwoofer.There are certain things that 5.1-channel surroundsound systems do well compared to 2-channelstereo. For example, it is possible to move soundsacross the front seamlessly. It is also possible tocreate ambience behind the listener. But 5.1 channelsurround systems do not provide enough channelsfrom which to render the required refl ectedsound components for a seamless and envelopingsoundstage. Unfortunately, the additional two backsurround channels in 7.1-channel systems are notin the right place to provide a significant perceptualimprovement.Adding more channels to a surround system isnot for special effects. Accurate spatial soundreproduction requires rendering of directionalsound cues and non-directional ambient cues.Refl ections arriving after the direct sound play acritical role in the perception of soundstage widthand depth. To have the most impact, additionalsurround channels should be used to control thedirection, time of arrival, and frequency responseof the refl ected sound to render an expandedsoundstage that reproduces sound with betterlocalization and envelopment than what 5.1-channelsystems provide.Research in the perception of auditory source widthhas shown that there are strong preferences in thedirection of refl ected sound and the perception ofsoundstage width and spaciousness. The singlemost important direction of side-wall refl ectionsis ±60°. DSX provides a pair of Wide channels(LW and RW) at ±60° with appropriate frequencyresponse and perceptual processing to match therequirements of human hearing. In fact, the Widechannels are much more critical in the presentationof a realistic soundstage than then Back Surroundchannels found in traditional 7.1-channel systems. Amore enveloping 7.1-channel system is one in whichWide speakers are used instead of Back Surroundspeakers. Adding surround channels behind thelistener has a very small impact compared to theincrease in envelopment and soundstage width thatthe front wide channels will provide.After side refl ections, the next most importantacoustical and perceptual cues come from reflections above the front stage. DSX provides a pairof Height channels (LH and RH) at a ±45° azimuthangle and elevated to a 45° angle in the medianplane.In addition to creating new Wide and Heightchannels, DSX also provides Surround Processingto enhance the envelopment of the Surround andBack Surround channels (if present). DSX SurroundProcessing processes the standard surround signalsin the time and frequency domains to improve theperceived sense of envelopment and blending withthe other speakers in the surround system.Audyssey Dynamic Surround Expansion is a scalablesystem that can adapt to the practical needs of theuser. The first level of surround stage enhancementcomes from adding the Wide channels. The secondlevel comes from adding the Height channels. If itis practical to have both Wides and Heights thenthe surround performance will be further enhanced.DSX automatically reconfigures its processing tooptimize surround rendering over any number ofavailable speakers beyond that of 5.1-channel.Audyssey Dynamic EQ®Audyssey Dynamic EQ solves the problem ofdeteriorating sound quality as volume is decreasedby taking into account human perception and roomacoustics. Audyssey Dynamic EQ works in tandemwith Audyssey MultEQ XT 32 to provide well-balanced sound for every listener at any volumelevel.Audyssey Dynamic Volume®Audyssey Dynamic Volume solves the problem oflarge variations in volume level between televisionprograms, commercials, and between the soft andloud passages of movies. Audyssey Dynamic EQis integrated into Dynamic Volume so that as theplayback volume is adjusted automatically, theperceived bass response, tonal balance, surroundimpression, and dialog clarity remain the same.Audyssey MultEQ® XT 32Audyssey MultEQ XT 32 is a room equalizationsolution that calibrates any audio system so thatit can achieve optimum performance for everylistener in a large listening area. Based on severalroom measurements, MultEQ XT 32 calculates anequalization solution that corrects for both timeand frequency response problems in the listeningarea and also performs a fully automated surroundsystem setup.Auto Lip SyncIf you connect the receiver to a TV that supports theAuto Lip Sync function, it can automatically correctdelay between the audio and video.DDeep ColorThis technology allows expression of more numberof colors than the conventional 8 bits and canreproduce colors close to natural ones without colorstreak.DENON LINKDENON LINK is a unique digital, balanced transfertype interface developed by DENON. It offers highspeed, high quality transfer of digital audio datawith low signal loss. It can be used together witha DENON Blu-ray disc / DVD player equipped witha special DENON LINK connector using a singlecable to enable playback with high sound quality.It allows digital transfer of the 192 kHz/24 bit2-channel digital signals of DVD-Audio discs, PCMmulti-channel signals, etc. Full-spec digital transferof the audio contents of Super Audio CD is possibleby connecting a player equipped for DENON LINK3rd Edition.During processing of DENON LINK, theindicator of the display lights.DENON LINK 4th uses the clock of the AV amplifierconnected by DENON LINK to achieve HDMI signaltransfer with low jitter when playing BD.DLNADLNA and DLNA CERTIFIED are trademarks and/or service marks of Digital Living Network Alliance.Some contents may not be compatible with otherDLNA CERTIFIED™ products.Dolby DigitalDolby Digital is a multi-channel digital signal formatdeveloped by Dolby Laboratories.A total of 5.1 channels are played: 3 front channels(“FL”, “FR” and “C”), 2 surround channels(“SL” and “SR”) and the “LFE” channel for lowfrequencies.Because of this, there is no crosstalk betweenchannels and a realistic sound field with a “three-dimensional” feeling (sense of distance, movementand positioning) is achieved.A realistic, powerful sense of presence is achievedwhen playing movie sources in AV rooms as well.
