LINE VOLTAGE ADJUSTMENT 

 
 
The Goldmund Mimesis 27.8 uses an internal power supply developed by Goldmund to 
provide totally separate voltage between the USB part and the digital/analog circuitry. 
 
Your power supply unit has been set to operate with the mains voltage of your area. Check 
on the power supply voltage switch on the rear panel if there is any doubt. If you move after 
purchasing the preamplifier to an area using a different AC mains voltage, you can change 
the voltage yourself or consult your local Goldmund dealer for assistance in doing so. 
 
The voltage selector on the rear panel allows choosing between 220V (234V nominal) and 
110V (117V nominal). 
 
Please refer to the Technical Specifications at the end of this manual for the main line 
voltage range. 
In case the nominal line voltage in your country is out of range, please consult your local 
Goldmund dealer for assistance. 
 
The power supply unit can operate indifferently with both 50 and 60 Hz AC line.
