SETTING UP THE MIMESIS 22H (Ctd.)  

 
 

1.3  

CHOICE OF PREAMPLIFIER LOCATION 

 
 
The  Goldmund  MIMESIS  22H  preamplifier  generates  a  significant  amount  of  heat.  It  is 
necessary  to  allow  adequate  ventilation  for  proper  cooling  of  the  heat  sinks.    Avoid  any 
location  which  is  not  properly  ventilated.  Avoid  stacking  equipment  and  do  not  locate  the 
preamplifier close to equipment that is sensitive to temperature. 
 
The power unit has been especially designed to minimize transformer vibration effects on 
the  audio  circuits.  One  consequence  of  this  strategy  is  that  the  power  supply  unit  is 
physically  separate,  connected  by  only  the  150mm  cabling.    The  power  supply  and 
preamplifier  should  be  located  as  far apart as the cabling allows. The preamplifier should 
ideally  not  be  located  above  the  power  supply.  The  power  supply  most  certainly  should 
never  be  located  above  the  preamplifier  as  this  would  force  transformer  vibration 
evacuation through the audio circuits on its way to ground. 
 
The  power  supply  also  generates  a  significant  amount  of  heat  and  the  ventilation 
requirements noted above also apply. 
 
The  preamplifier  has  been  designed  with  four  adjustable  conical  feet.  These  are  used  to 
ensure  proper  vibration  transmission  to  the  preamplifier  support  in  order  to  evacuate  all 
detrimental  vibrations  inside  the  unit,  following  the  famous  Goldmund  "Mechanical 
Grounding"  principle.  Depending  on  the  flatness  of  the  chosen  location,  you  may  have  to 
adjust one or more of these feet.
