GOLDMUND MIMESIS 37S - Analog Preamplifier - 6
1 SETTING UP THE MIMESIS 37S (Ctd.)
1.3 CHOICE OF PREAMPLIFIER LOCATION
The Goldmund Mimesis 37S 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.
