INTRODUCTION
GOLDMUND MIMESIS 22 HISTORY Analog 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, home-networking and music
distribution.
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.

1.1 PRELIMINARIES
For exacting technicians, musicians, and all high-fidelity music purists who demand the
very best in reproduction, we strongly recommend the use of top quality power amplifiers,
since most of the analog signal integrity delivered by the preamplifier can be destroyed by
using lower quality amplifiers.
For perfect analog amplification, Goldmund recommends the Goldmund Telos series of
power amplifiers.
The connection between the analog sources and the preamplifier as well as between the
preamplifier and the power amplifiers are also critical. Ultra low reflection interconnect
cables are absolutely mandatory to retain the time integrity that the preamplifier is designed
to provide. In all typical cases Goldmund recommends using the special Goldmund Lineal
interconnect cables.

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.

1.4 LINE V0LTAGE ADJUSTMENT
Warning! If the line voltage provided is not appropriate as supplied, please consult your
dealer.
ATTENTION: At the 220V position, the Goldmund MIMESIS 22H preamplifier will function
properly for main line voltages between 200V and 240V. At the 110V position, the main line
must deliver between 105 and 125V. If your main supply operates out of these tolerances,
please consult your Goldmund dealer.
This fuse is located on the power cord receptacle and can be accessed by raising the
cover using a small screwdriver when the powercord has been removed (ensuring power is
disconnected before handling). Use a 2.5A slow-blow fuse.
Warning! Always ensure that the fuse cover is fitted. Fuses are for fire prevention and do
not protect against risk of electric shock.
1.5 CONNECTIONS
Warning! Always remember that a plug with bared connectors is dangerous if in contact
with a live socket. This appliance must be earthed.
Connect the non-rewirable power cord supplied to the back of the power supply and plug it
into the nearest wall plug. Use only a 3 lugs grounded plug, for safety and noise reasons.
Replacement mains leads can be obtained from your Goldmund retailer.
To get the best sound of the preamplifier, avoid any multiple plugs or extension cords.

1.5 CONNECTIONS (C d.)
Warning! Take care to always handle the cable by the connectors. Never twist the cable
excessively or attempt to connect or disconnect the connector by handling the cable body
in place of the connector.
Connect the cabling from the power supply output to the preamplifier input point labeled
“Power”.
Warning! The next stage in setting up your MIMESIS 22H is to connect your sources,
power amplifiers and other peripheral devices. All devices should be disconnected from
mains power until safe.
Connect the preamp analog output interconnects to the power amp using the RCA female
sockets labeled “analog outputs”.
Connect the interconnect cables from source devices to the line inputs numbered 1 to 7
labeled ‘IN1’ to ‘IN7’.
Connect tape machines to any inputs and to the Tape output RCA plugs.
Note:
Do not use the direct input labeled “SSP Input” if you are not using a linked configuration
with a Goldmund Mimesis 20. If your configuration includes the special software modules
which allow the connection of several units together, use the DB9 terminated cable
provided with this option to connect the MIMESIS 22H to these units and follow the
instructions delivered with the software.
In that case only, use only the direct input marked “SSP Input” to connect the analog
output of the Mimesis 20 to the MIMESIS 22H analog input module.

2 POWER SUPPLY
2.1 POWER SUPPLY
The main POWER switch is located on the back panel of the Goldmund MIMESIS 22H
power supply. In regular use, this switch should be left permanently ON and the circuits of
the preamplifier activated or deactivated using the STANDBY ON/OFF.
When the POWER switch is switched ON, the preamp will become operative after few
seconds delay to ensure proper stabilization of all the circuitry and avoid any unwanted
noise. After this delay, the output of the preamplifier is connected to the power amplifier.
The preamplifier can be powered off by switching the POWER switch to the OFF position.
A special safety circuit switches the preamp to MUTE to avoid any disturbance reaching
the power amplifier and the speakers, even if the preamplifier is disconnected from the
mains supply by accident. However, to optimize the sound quality of the preamplifier and
ensure the reliability, the M22S should remain powered ON continuously and is only
deactivated using the Standby function.

3 CONTROLS & UTILIZATION
The Goldmund MIMESIS 22H is designed to capture, control, shape and nurture the fragile
source inputs, supporting adjustment of volume and balance to deliver your desired output
signal. The primary control functions supporting these processes are outlined below.
3.1 STANDBY
To activate the preamplifier (set to ON) put it into STANDBY ON mode by pressing the
SET/PWR (1) and the MUTE/PWR (3) buttons simultaneously.
To deactivate the Preamplifier (set to OFF) press these same SET/PWR (1) and
MUTE/PWR (3) buttons simultaneously once more.
In standby mode, the two red leds near the PWR button will be illuminated intermittently
(approximately every five seconds).
3.2 INPUT SELECTION
To select the source you want to listen to, use buttons ‘IN1’ to ‘IN7’ (2) to activate each of
the 7 input options. When the input is activated, the Led on the button corresponding to the
selected input will be illuminated.
3.3 VOLUME ADJUSTMENT
The right-hand volume level adjustment knob (7) is used to adjust VOLUME. If volume is
set to a value of zero, outputs will be muted.
