4  Positioning 

 
 
The PREAMP I 

– MK 3 has no special requirements regarding its position. You can even put the unit 

in  a  cupboard.  For  reasons  of  better  access  to  the  various  input  and  output  sockets  we  recommend 
you position the unit in an audio rack. Professionally designed audio racks can have a positive effect 
on the music reproduction of your audio system. 
 
 
 

 
IMPORTANT ! 

 
Please observe at all times. 
 
Before  you  connect  the  unit  with  some  other  unit  using  a  cable,  please 
never  forget  that  both  units  must  first  be  switched  off  and  disconnected 
from the mains power.
