USB Connection

Before  connecting,  make  sure  all  of  the  audio  levels  are  turned  down  or 
system is turned off; this helps to prevent clicks and pops from damaging 
more sensitive equipment when connecting and powering up. 

Turn  on  your  computer;  once  initiated,  connect  a  USB  cable  from  your 
computer  to  the  DI-USB  Box.  Note  that  the  DI-USB  employs  a  USB 
type-B connector which is standard for devices that are upstream from the 
computer ; once connected, your computer will automatically recognize the 
UNIKA DI-USB. 

The generic drivers are compatible with most operating systems,

 

including 

Mac OSX, Windows 10 and Windows 7/8.  

The DI-USB Box’s USB LED will illuminate to let you know it is connected. 

Go to your system settings/control panel and select the UNIKA DI-USB in 
the Audio/Sound  settings.  Close  and  save  your  system  preferences,  and 
open the audio playback program of your choice, select and play an audio 
file. To check the audio, plug in a set of headphones or ear buds and listen. 
So  set  the  level  control  to  7  o'clock  (fully-counter-clockwise)  and  then 
increase slowly.

The  DI-USB  is  designed  to  be  plug  and  play  for  easy  use. The  following 
describes basic set-up procedures and connections.

USB type A connect to laptop

USB type B connect to DI-USB
