Explanation of Terms
Research in the perception of auditory source width has shown that 
there are strong preferences in the direction of reflected sound and the 
perception  of  soundstage  width  and  spaciousness. The  single  most 
important direction of side-wall reflections is ±60°. DSX provides a pair 
of Wide channels  (LW  and RW) at  ±60°  with  appropriate frequency 
response  and  perceptual  processing  to  match  the  requirements  of 
human hearing. In fact, the Wide channels are much more critical in 
the  presentation  of  a  realistic  soundstage  than  then  Back  Surround 
channels  found  in  traditional  7.1  systems.  A  more  enveloping  7.1 
channel system is  one  in  which Wide speakers  are  used instead of 
Back Surround speakers. Adding surround channels behind the listener 
has a very small impact compared to the increase in envelopment and 
soundstage width that the front wide channels will provide.
After  side  reflections,  the  next  most  important  acoustical  and 
perceptual  cues  come  from  reflections  above  the  front  stage.  DSX 
provides a pair of Height channels (LH and RH) at a ±45° azimuth angle 
and elevated to a 45° angle in the median plane.
In  addition  to  creating  new  Wide  and  Height  channels,  DSX  also 
provides  Surround  Processing  to  enhance  the  envelopment  of  the 
Surround  and  Back  Surround  channels  (if  present).  DSX  Surround 
Processing processes the standard surround signals in the time and 
frequency domains to  improve the perceived sense of envelopment 
and blending with the other speakers in the surround system.
Audyssey Dynamic Surround Expansion is a scalable system that can 
adapt  to  the  practical  needs  of  the  user. The  first  level  of  surround 
stage  enhancement  comes  from  adding  the  Wide  channels.  The 
second level comes from adding the Height channels. If it is practical 
to have both Wides and Heights then the surround performance will 
be  further  enhanced.  DSX  automatically  reconfigures  its  processing 
to optimize surround rendering over any number of available speakers 
beyond 5.1.

DENON LINK
DENON  LINK  is  a  unique  digital,  balanced  transfer  type  interface 
developed  by  DENON.  It  offers  high  speed,  high  quality  transfer  of 
digital audio data  with low signal  loss. It can  be used together  with 
DENON AV Amplifier equipped with a special DENON LINK connector 
using a single cable to enable playback with high sound quality. It allows 
digital transfer of the 192 kHz/24 bit 2-channel digital signals of DVD-
Audio discs, PCM multi-channel signals, etc. Full-spec digital transfer 
of the audio contents of Super Audio CD is possible by connecting a 
player equipped for DENON LINK 3rd Edition.
During  processing  of  DENON  LINK,  the  “ ”  indicator  of  the 
display lights.
DENON  LINK  4th  uses  the  clock  of  the  AV  amplifier  connected  by 
DENON LINK to  achieve HDMI signal  transfer with little  jitter when 
playing BD.
AL24 Processing Plus
AL24 Processing for All Channels
DENON  has  further  developed  its  proprietary  AL24  Processing,  an 
analog  waveform  reproduction  technology,  to  support  the  192  kHz 
sampling  frequency.  AL24  Processing  Plus,  thoroughly  suppresses 
quantization noise associated with D/A conversion of LPCM signals to 
reproduce the low-level signals with optimum clarity that will bring out 
all the delicate nuances of the music.
Equipped  foe  not  only  front  left  and  right  channels  but  also  for  the 
surround left and right, center and subwoofer channels.
