1- IIS/I2S Digital Output.           

2- Optical Digital Output. 

3- EBU/AES Digital Output.   

4- RCA Coaxial Digital Output. 

5- BNC1 Coaxial Digital Output.     6- BNC2 Coaxial Digital Output (Current Mode Output). 

7- Power Input Interface (Including fuse, Power switch). 

Note: 

BNC2 coaxial digital output belongs to current output mode; it needs 75 ohms resistance 

to  ground  from  receiving  end  which  can  restore  current  into  voltage  signal.  Therefore,  maybe 

there  are  less  than  10%  DAC  cannot  lock  signals  normally  due  to  the  absence  of  such  input 

resistance. If your equipment belongs to this type, you can choose the other two coaxial output.   

There  are  subtle  differences  among  the  three  coaxial  output  in  tones,  you  can  choose  the  port 

you like after comparison.

-GND 

Note:

  When  you  homemade  IIS  cable,  super  5  category  twisted  pair  cable  is  recommended, 

every  signal  line  should  be  twisted  together  with  one  GND.  At  the  same  time,  we  do  not 

recommend the length of 12S line more than 50CM.
