GOLDMUND MIMESIS 27.5 - Analog Preamplifier - 7 

FIRST INSTALLATION & CONNECTIONS 

 
 

2.1.   POWER CONNECTION 

 
Connect the power cord to the back of the preamplifier and plug it into the nearest wall 
plug. Use only a 3 lugs grounded plug, for safety and noise reasons. To get the best sound 
of the preamplifier, avoid any multiple plugs or an extension cord. 
 
If the preamplifier is the logical center of your system and you use a star grounding 
configuration, you may have to use the earth connection of the AC plug and lift the earth 
connection of the other equipment. In such a case, connect together the earth 
(yellow/green). 
 
If you have to update the software, you will use the DB9 terminated cable provided with this 
option to connect the Mimesis 27.5 to a computer serial output and follow the instructions 
delivered with the software. This connector has to be left open in all the other situations. 
 
 

2.2.   SOURCES CONNECTION 

 
Connect the interconnects between the preamp analog outputs and the power amp. You 
will plug the cables to the RCA female sockets noted outputs. 
Connect the interconnects from the analogue source devices to the line inputs number 1 to 
5. With the D/A option connect the lineal cables from the digital sources to the inputs 
number 6 to 8. 
 

Note

: a residual High Frequency noise may remain audible in some circumstances when 

an input is left open and is selected. This disturbance has no effect on the preamplifier but 
may be avoided easily by short-circuiting plugs applied to all the unused inputs. 
 
Connect the tape machines to input 5 and to the Tape output RCA plugs.
