Introduction
Thank  you  for  purchasing  this  Clarett  8PreX,  one  of  the  family  of  Focusrite  professional  
Thunderbolt™  audio  interfaces  incorporating  newly-designed,  high  quality  Clarett  analogue  
pre-amplifiers with the unique AIR function. In conjunction with the Focusrite Control application, 
you now have a highly versatile and professional solution for routing high quality audio to and from

once you have configured it using Focusrite Control software.
This  User  Guide  provides a detailed  explanation  of  the  hardware  to  help  you  achieve a thorough
