HDMI native DSD interface

      HDMI  interface  could  support  both  1080p  video  and  8-
channel high definition digital audio with bandwidth as high 
as  18Gbps. The  Native  12S  and  DSD  digital  audio  internal 
bus are built in the main internal bus of the HDMI interface, 
making  audio  transport  without  any  format  conversion.  It 
could  transmit  8-channel  of  PCM  audio  with  24bit  192Khz 
directly and DSD native audio stream with 1bit 5.6Mbps. 

      The  decoding  process  is  that  HDMI  native  DSD  bus 
interface  could  transport  the  DSD  original  format  audio 
stream received from the output of SACD or blue ray SACD 
HDMI  interface  to  DSD  internal  bus  of  ESS9018  chip 
without  any  format  conversion  process,  which  realizes  an 
authentic  DSD  native  data  decoding  directly  and  ensures 
the 100% realistic reproduction of music.

2.Based on the Latest Xmos DSD Solution

  Another biggest feature is that the latest Xmos is equipped 
with built-in DCA , which not only supports Native DSD data 
transportation provided by USB Audio Class 2.0 but also be 
compatible  with  the  current  common  DSD  mode  of  Dop 
mode.  The  Xmos  USB  core  technology  could  input  Native 
D S D   d a t a   w h i c h   i s   u p   t o   3 2 - b i t / 3 8 4 k H z   P C M ,  
DSD64/2.8Mhz,  DSD128/5.6Mhz  and  DSD256/11.2Mhz  to 
the  USB  audio  interface.  Except  for  the  traditional  PCM 
digital  stream,  it  supports  all  popular  PC  digital  audio 
format  but  also  the  decoding  for  the  native  stream  of  DXD 
and DSD. 

3.  Dual  ESS9018  DAC  design  with  8-channel  parallel 
mono output mode

      Audio  decoding  is  powered  by  2  groups  of  ESSSabre 
ESS9018  chip  with  patented  technology  of  32  bit”Time 
Domain”eliminate  jitter  clock,  and  digital  audio  data  is

32bit/384kHz,DSD64/DSD128  and  DSD256  by  Xmos  USB 
interface. As a result, it could be compatible with those high 
resolution format without any further upgrade. At the same 
t i m e ,  i t  i s  e q u i p p e d  w i t h  a  T C X O ( Te m p e r a t u r e 
Compensated Crystal Oscillato) with ultra high accuracy as 
little  as  1ppm  so  that  the  high  dynamic  high  contrast 
characteristic  of  high  resolution  digital  audio  could  be 
perfectly  remain.  You  could  enjoy  an  unprecedented 
experience even though playing the compressed audio like 
MP3.

4.Pure analogue power design

   The power system of digital circuits and analogue circuits 
are  separated  that  ensures  the  pure  and  accurate 
reproduction.  Digital  part  is  totally  isolated  from  analogue 
parts  from  power  to  circuit  board,  and  the  internal  cables 
are as less as possible so as to reduce the interfere with the 
sound. The circuit board design use the quality sound as a 
starting point with sophisticated materials.

        The  apparatus  has  a  built-in  authentic  hi-end  analogue 
preamplifier  featuring  with  a  finely  tuned  DAC  which  could 
set  a  proper  level  balanced  XLR  output  to  amplifier.  The 
preamplifier  part  has  a  built-in  Pre  out  output  interface  so 
as  to  connect  the  external  audio  equipment.  The  output  of 
single-ended  signal  is  provided  by  high  quality  bandwidth 
and  ultra  CMRR  transformer,  being  completely  consistent 
with  the  sound  from  the  XLR  output  and  providing  a  more 
suitable  sound  for  the  audiophile  within  the  sound 
characteristic of big dynamic, high density and vigorous. 

5. Floating design

   The floating designed DAC has a instrument level single-
ended  output  module(audio  coupling  transformer)  with 
CMRR  up  to  90dB  and  bandwidth  up  to  22Mhz.  It  could 
provide  large  dynamic  and  wide  bandwidth  audio  single-
ended  output  with  reduction  rate  of  100%  symmetric 
i n t e r f a c e ,  m a k i n g  t h e  s o u n d  m o r e  l i s t e n a b l e  a n d 
interesting. Audiophiles could enjoy the high quality sound 
from symmetric interface by the single-ended output.

Ultra-low  distortion  with  high  precision  balanced 

analog volume potentiometer

      The  output  volume  from  the  traditional  DAC  decoder 
which  supports  high  level  pre  amplifier  output  is  adjusted 
by  DAC  chip  digital  attenuator,  however,  we  chose 
balanced  analog  amplified  volume  attenuation  system 
modules , as a result, linear regulation could be accurate to 
0.5db  per  step,  making  the  volume  control  more  smoothly 
without  any  distortion  and  noise  from  the  traditional 
potentiometer. 

      Model  one  could  be  used  as  a  preamplifier  as  the  DAC 
symmetric output level could be up to 2.7v rms and the non 
symmetric  one  could  be  up  to  1.2v  rms.  A  pure  analog 
symmetric  high  precision  potentiometer  is  designed  at  the 
output,  which  could  control  the  output  volume  level  more 
precise with 0.5db per step from 90db to 0db. The analogue 
symmetric audio signal outputs directly via symmetric level 
adjustment  so  as  to  realize  the  control  to  the  preamplifier 
output  volume  which  is  convenient  for  connecting  dual 
amplifier or high quality active subwoofer. 

7. The heavy weight double sandwich chassis design

      The  ultra-thick  combined  sandwich  chassis  is  made  by 
mixed  material  with  a  design  of  unique  suspension  and 
shock-absorbing  technology.  The  customized  shock-
absorbing material is sandwiched between steel casing and 
thick  aluminum  alloy  chassis  base,  which  could  eliminate 
the bad effect of vibration to the sound subtly with the large 
bronze spikes and realize a perfect suspension. The effect 
of  perfectly  isolating  from  the  interference  of  the  external 
vibration and eliminating the mechanical resonance itself is 
far  more  than  a  common  so-called  heavy  weight  materials 
designed with single material.

   The internal circuit boards and components are all coated 
by  shock  abortion  material,  which  could  completely 
eliminate the effects of subtle vibrations due to the  voltage 
and  current  that  generated  by  working  component  to  the 
sound,  as  a  result  it  could  significantly  increased  the 
cleanliness  and  fluency  of  the  sound.  All  the  electronic 
components  are  working  in  exactly  the  same  temperature 
due to the hermetic chassis, which prevents the component 
and circuits from being corroded by dust and moisture, thus 
increasing the service life. 

8. Fully balanced high-speed analog amplifier circuit 

   The available bandwidth of the apparatus could reach to 
650  kHz  in  (-3dB)  and  ensure  the  flat  of  the  frequency 
response  within  listening  range,  which  can  perfectly 
reproduce the high resolution files and the essence of high-
contrast  and  high  bandwidth  for  the  new  generation 
recording.  Not  only  ensures  the  available  wide  bandwidth 
but  it  also  allows  the  rotation  rate  to  reach  to  excellent  as 
85Vus(p-p),  and  the  result  is  that  the  reproduction  details 
will  not  be  dragged  and  fuzzy,  like  accurately  focusing  a 
high resolution pictures. Thanks to the selective transistor, 
the High power could coexist with low distortion, and there 
is  absolutely  no  roughness  like  the  normal  transistor.  The 
paired  transistors  are  working  in  the  environment  of  the 
same temperature and low vibration due to the built-in non 
r e s o n a n c e  t h e r m a l  d e s i g n  a n d  f u r t h e r  t h e  m u s i c 
reproduction perfectly .The key to make the music alive and 
rich is that the full range has a very low distortion while full 
power output.
