Getting Started Connections Settings Playback Remote ControlMulti-zone Information Troubleshooting SpecificationsInformationENGLISHExplanation of TermsResearch in the perception of auditory source width has shown thatthere are strong preferences in the direction of reflected sound and theperception of soundstage width and spaciousness. The single mostimportant direction of side-wall reflections is ±60°. DSX provides a pairof Wide channels (LW and RW) at ±60° with appropriate frequencyresponse and perceptual processing to match the requirements ofhuman hearing. In fact, the Wide channels are much more critical inthe presentation of a realistic soundstage than then Back Surroundchannels found in traditional 7.1 systems. A more enveloping 7.1channel system is one in which Wide speakers are used instead ofBack Surround speakers. Adding surround channels behind the listenerhas a very small impact compared to the increase in envelopment andsoundstage width that the front wide channels will provide.After side reflections, the next most important acoustical andperceptual cues come from reflections above the front stage. DSXprovides a pair of Height channels (LH and RH) at a ±45° azimuth angleand elevated to a 45° angle in the median plane.In addition to creating new Wide and Height channels, DSX alsoprovides Surround Processing to enhance the envelopment of theSurround and Back Surround channels (if present). DSX SurroundProcessing processes the standard surround signals in the time andfrequency domains to improve the perceived sense of envelopmentand blending with the other speakers in the surround system.Audyssey Dynamic Surround Expansion is a scalable system that canadapt to the practical needs of the user. The first level of surroundstage enhancement comes from adding the Wide channels. Thesecond level comes from adding the Height channels. If it is practicalto have both Wides and Heights then the surround performance willbe further enhanced. DSX automatically reconfigures its processingto optimize surround rendering over any number of available speakersbeyond 5.1.Manufactured under license from Audyssey Laboratories.

It offers high speed, high quality transfer ofdigital audio data with low signal loss. It can be used together withDENON DVD player equipped with a special DENON LINK connectorusing a single cable to enable playback with high sound quality. It allowsdigital transfer of the 192 kHz/24 bit 2-channel digital signals of DVD-Audio discs, PCM multi-channel signals, etc. Full-spec digital transferof the audio contents of Super Audio CD is possible by connecting aplayer equipped for DENON LINK 3rd Edition.During processing of DENON LINK, the “ ” indicator of thedisplay lights.DENON LINK 4th uses the clock of the AV amplifier connected byDENON LINK to achieve HDMI signal transfer with little jitter whenplaying BD.AL24 Processing PlusAL24 Processing for All ChannelsDENON has further developed its proprietary AL24 Processing, ananalog waveform reproduction technology, to support the 192 kHzsampling frequency. AL24 Processing Plus, thoroughly suppressesquantization noise associated with D/A conversion of LPCM signals toreproduce 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 channels but also for thesurround left and right, center and subwoofer channels.“AL24 Processing Plus” operates in a system with 8.1 channels ormore when digital (PCM) signals are input and the surround mode isas follows:PURE DIRECT ◦MULTI CH PURE DIRECTDIRECT ◦MULTI CH DIRECTSTEREO ◦MULTI CH IN•••®, HDCD®, High Definition Compatible Digital® andMicrosoft® are either registered trademarks or trademarks ofMicrosoft Corporation, Inc. in the United States and/or othercountries.

Other patents pending.Advanced AL24 Processing MultichannelEquipped with “Advanced AL24 Processing” time axis regioninformation volume expansionIn addition to the existing “AL24 Processing Plus” bit expansiontechnology, DENON has also developed “Advanced AL24 Processing”that dramatically improves information volume in the time axis regionusing high-speed signal detection and processing technology. Inaddition to expanding original 16-bit digital data to 24 bits, “AdvancedAL24 Processing” uses data interpolation along the time axis orupconverted sampling to achieve natural interpolation without losingthe original data. A digital filter is used to further expand adaptabilityand perform optimum filtering calculations for ringing-free pulseresponse, pulsive music data and attack sounds.This results in the reproduction of such spatial information as thedelicate nuances in the music, the positions of the performers, andthe breadth, height, and depth of the concert hall. “Advanced AL24Processing” is conducted for all channels and modes other than DSDDIRECT.It also operates when the system is 7.1-channel or below. |
