Please not:
        The DAC had burn in over 100 hours before shipping .
        You can power on it with playing music if you are at home for quickly finished burn in. If you don't want listen music during the burn in term, you can turn the amp volume to minimum.
        Please power off before connect or disconnect the inputs and outputs .
        Power on the product must had more than the half minute after last power off .


Function introduce :
         The DAC can setting the digital process functions on front plate to change the sound flavors, without open the unit .

   

Important warn:
         Before push the "Setting" button, we are advice user turn  low  the amp volume, stop the music track playing .
         Because for the aim to reproduce the best sound quality, the DAC without mute design , change the setting may output circuit switch sound .
         Around 5 seconds after non any button had push, the display stop blink, user can click the music track to playing and  turn up the volume.

Setting button :
          The setting menu had two pages. The first page had 3 digit LEDs display , and the second page had 2 digit LEDs display.
          Push the "Setting" button one time, the one digit display will blink for active the function setting , push the "Selector" buttons can change function . While the display blink, push "Setting" again , the next digit display will blink . If the Synchronizer blink but push the "Setting" , the menu will change to 2nd page .

       

OS/NOS (Oversampling) :
         "O" for select oversampling, "N" for select NOS mode.

Mode  ( OS and NOS modes):
          While OS setting on "O" mean the DAC working under oversampling mode, lower number OS modes sound became warmer and smoother. Or depend on your sense .
         Mode "0" : class technology NOS mode.
         Mode "2" : 2X oversampling.
         Mode "4" : 4X oversampling .
         Mode "8" : 8X oversampling.

         While OS setting on "N" mean the DAC working under NOS mode, different modes offer different sound features, usually mode 3 is most users favorite. Or depend on your sense .
         Mode 1 : Simplest data process .
         Mode 2 : Data fifo.
         Mode 3 : Fastest data process.

Synchronizer :
          If the HDMI input had noise, distortion or some samplings no sound, user can setting the synchronizer ON (1) or OFF (0) to fixed the issue. In default is OFF (0) .

PLL :
           Active (1) or Disable (0)  PLL for USB and HDMI inputs, we are advice setting Active (1) for the low performance source but Disable (0) for the high performance source, or depend on yourself sense .

Display :
         Active (1)  the display auto dark, the display will become dark in around 10 seconds after stop operate the buttons . Disable (0) the display auto dark, the display  light always.

Selector buttons:
           While the display non blink (Don't push the "setting" button at first ), for select the input 1 to input 4.
          While the display blink (Push the "setting" button at first), for setting the digital  functions.
