Home Screen 

 

The  home  screen  provides  basic  overview  of  the  HDMI  link  status  and  digital  audio 

properties. 

 

MODE: Indicates whether the incoming audio format is PCM 

or DSD. 

SAMPLING  RATE:  Indicates  incoming  sampling  rate.  Valid 

sampling rates are: 44.1, 48, 88.2, 96, 176.4 and 192kHz. 

The  sampling  rate  indicator  also  shows  the  status  of  the 

clock recovery system. When the algorithm is actively locking 

onto the incoming clock rate, the indicator turns orange.  

BIT  RESOLUTION:  Indicates  detected  bit  resolution  in  the 

range between 10 and 24 bits and MUTE when no valid bits 

are  present.  The  bit  depth  detection  algorithm  monitors  the  real  number  of  bits  used 

(continuously changing). It is possible that the detected bit resolution sporadically changes during 

playback depending on the actual signal conditions and playback method. This applies primarily 

to compressed audio sources. 

SIGNAL STATUS: Indicates the status of the incoming audio signal, RUN or STOP. 

CHANNELS: Indicates number of valid channels in the range from 2 up to 8. 

HDMI IN and HDMI OUT:  Indicate whether a HDMI link is established on the input or the output 

connector.  Red  colour  indicates  no  HDMI  connection.  Green  colour  indicates  established  HDMI 

link.  

Audio Setup 

 

In  this  screen  the  user  can  configure  several  parameters  of  the  DSD  to  PCM  conversion 

algorithm, DSD output mode, 4.0 downmix and output volume. 

 

Sampling Rate: Sets the output sampling rate for DSD to PCM 

conversion. The options available are 88.2 and 176.4kHz. 

Bit  Resolution:  Sets  the  output  bit  depth  for  DSD  to  PCM 

conversion.  The  options  available  are  16  and  24  bits.  The 

16-bit  option  can  be  useful  for  owners  of  so-called  non 

oversampling  (NOS)  DACs  or  older  devices  designed  to 

accept 16-bit word length only. In all other cases the 24-bit 

options should be selected. 

Filter: Sets the DSD to PCM conversion filter characteristics. 

There  are  4  options  available.  Sharp  HB,  Slow  HB,  Sharp  LB  and  Slow  LB.  See  the  following 

paragraph for filter details.  

PCM Matching: Enables or disables the PCM and DSD output  level matching function. With 0dB 

setting,  PCM  is  passed  through  bit  accurate  without  attenuation.  With  -3dB  setting,  the  PCM 

material gets attenuated by 3dB to match the output level from the DSD to PCM converter. 

DoP  Output:  Enables  or  disables  raw  DSD  output  in  the  DoP  format.  Use  only  if  your  DAC  can 

accept DoP signal.  

DSD 4.0 Downmix: Enables or disables the internal DSD 4.0 downmix function. 

Output Volume: Sets the fixed level of the output signal. The range is from 0dB down to -100dB. 

Select 0dB for bit accurate signal path with no attenuation.
