INTRODUCTION

GOLDMUND MIMESIS 32 Universal Preamplifier

Goldmund was founded in 1978 and has ever since been dedicated to the accurate reproduction of

sound and image.

At Goldmund, we strive to lead in the creation, development and manufacture of the industry’s most

advanced technologies, including audio and video systems.

The guiding principle at Goldmund is to produce a precise sound with the least possible loss of

quality through the different stages. Goldmund will never adopt a technology before it is sufficiently

developed to satisfy the high quality standards we set. This is why Goldmund has often rejected

mainstream technologies and developed its own.

IMPORTANT

PLEASE DO NOT CONNECT ANY CABLES

OR MOVE ANY PARTS BEFORE READING

THE FOLLOWING INSTRUCTIONS.

GOLDMUND MIMESIS 32 - UNIVERSAL PREAMPLIFIER - 4

1 SETTING UP THE MIMESIS 32

1.1 PRELIMINARIES

Please read the following instructions very carefully. This high-precision unit will provide the

best digital signal possible to your digital-input power amplifiers thanks to its unique

technology.

For exacting technicians, musicians, and all high-fidelity music purists who demand the very

best in musical reproduction, we strongly recommend the use of top quality power amplifiers

with a digital input, since most of the digital signal performance delivered by the Mimesis 32

preamplifier can be eroded by using lower quality amplifiers or D/A converters.

The connection between the analog and digital sources and the preamplifier as well as

between the Mimesis 32 and the power amplifiers are critical. Ultra low reflection

interconnect cables are absolutely mandatory in analog and precise impedance SPDIF

cables in digital to keep the time integrity that the preamplifier is designed to provide. In all

typical cases Goldmund recommends using the special Goldmund Lineal interconnect and

digital cables.

1.2 UNPACKING

1 SETTING UP THE MIMESIS 32 (Ctd.)

1.3 CHOICE OF THE MIMESIS 32 LOCATION

Select a very rigid support, as required for your CD player transport.

The distance between the Mimesis 32 and the power amplifier is usually not critical since

the signal is carried in the digital domain. However, you must use coaxial links of highest

quality such as the Goldmund lineal in order to maintain the time accuracy and are highly

recommended, especially for long distances. For some high impedance output analog

sources, a short distance to the preamplifier is mandatory.

If you want to achieve the best possible sonic result, select an opposition on a shelf or on a

piece of furniture where the preamplifier is isolated from vibrations of mechanical

components, including the CD transport itself.

The Goldmund Mimesis 32 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.

1.4 POWER SUPPLY

The Goldmund Mimesis 32 uses multiple power supplies developed by Goldmund to provide

totally separate voltage to each part of the digital and analog circuitry.

Your power supply has been set to operate with the mains voltage of your area. Check on

the power supply voltage switch if there is any doubt. If you move after purchasing the

preamplifier to an area using a different AC mains voltage, consult your local Goldmund

dealer for assistance. An internal switch must be set for a correct AC selection.

The power supply unit tolerates both 50 & 60 Hz mains.

1 SETTING UP THE MIMESIS 32 (Ctd.)

1.4 POWER SUPPLY (Ctd.)

The internal switch 115/230 is not for the user to modify. On the 230 position voltages are

105 - 125 and 210 - 250 depending on the rear panel 110/220 switch. On the 115V position

the AC voltage may be lower (like the 100V for Japan)

1.5 FIRST INSTALLATION & CONNECTIONS

POWER CONNECTION

Plug the AC power cord to the power supply and into a wall socket.

The preamplifier is and remains on power as soon as the power switch located on the back

panel is turned on. For best sonic results, Goldmund recommends to leave the unit powered

on permanently.

When the machine is in standby mode, the front panel Led controls are off except the red

STBY Led, but the circuitry remains connected as long as the power supply switch is not

turned off. The Standby is controlled by the remote.

COMPUTER CONFIGURATION

Consult your local distributor for configuration.

1.5 FIRST INSTALLATION & CONNECTIONS (Ctd.)

SOURCES CONNECTION

Connect the analog sources or tape machines to the back panel analog inputs and the

digital sources to the digital inputs of the Goldmund Mimesis 32, using the RCA input

connectors for analog sources and the choice of RCA for SPDIF, XLR for AES-EBU or

optical for the digital sources.

The inputs are numbered on the back panel.

Digital inputs are numbered from 1 to 8. Digital input 3 and 4 offer two different connector

standards. Only one must be used per input, both work equally well. Digital input 7 and 8 are

reserved for HDMI connection.

Analog inputs are numbered from 9 to 14. The Analog input 12, 13 and 14 are switchable for

three separates 2-channel or one 6-channel input to connect SACD players or DVD audio

players.

If used with 6 channels, the connection must be made as follows:

Input 12L = Front Left

Input 12R = Front Right

Input 13L = Rear Left

Input 13R = Rear Right

Input 14L = Center

Input 14R = Subwoofer

Analog inputs have a common level adjustment inside the preamplifier (small blue switch

with 5 levers). Contact your local distributor to help you adjust the switch to the best adapted

input level.

Input level max:

All Switches OFF = 1.4 Vpp / 0.5 Vrms

Swicth 3 ON only = 8.5 Vpp / 3 Vrms (default setting)

Swicth 4 ON only = 15.6 Vpp / 5.5 Vrms

Swicth 5 ON only = 22.6 Vpp / 8 Vrms
