INTRODUCTION
GOLDMUND LOGOS 1N-2N SPEAKER SYSTEM– ACTIVE SPEAKER
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.

PRELIMINARIES
The LOGOS 1N-2N SPEAKER SYSTEM are made with one Logos 1N and one Logos 2N,
this speaker system uses very innovative technologies to achieve a level of definition and
neutrality never found before in a speaker system.
Please read very carefully the following instructions. These high-precision speakers are
extremely revealing and can provide the best sound only if they are used properly.
For exacting technicians, musicians, and all those who demand the very best in audio
reproduction, we strongly recommend using this speaker system with high quality
components, especially electronics and cables.

UNPACKING
The LOGOS 1N-2N SPEAKER SYSTEM requires special attention during unpacking,
because each unit is heavy and some handling steps require a lot of care. We recommend
the unpacking and installation of this unit to be performed by two persons. Some handling
steps necessitate a lot of care.
ATTENTION
If you need to return the speakers to the factory or to your local representative for a
warranty repair, please note that it must be repacked in the original packing. This
packaging has been specifically designed to protect the speaker in transit. Use of
alternative packaging will almost inevitably result in damage, which cannot be covered by
the warranty.
Unpack the speakers at their final location. Open the cartons and remove the speakers
and Logos-Frame components.

LOGOS 1N-2N SPEAKER SYSTEM FRAME
Please read very carefully the following instructions to avoid assembly errors.
Goldmund Logos 1N speaker and Logos 2N subwoofer are mounted with a support
system called Logos-Frame. The assembly instructions for the frame are detailed below.
If the speakers are already unpacked and at their final destination the unpacking details
can be ignored but the handling instructions must still be followed.
The component list for the support system is listed in the section Appendix page 12.

SELECTING THE SPEAKERS LOCATION
A very strong and rigid floor is essential for the optimal sonic result of your LOGOS 1N-2N
SPEAKER SYSTEM. Locate the speakers to have the most rigid possible coupling with
the floor. Solid coupling is also essential.
If your support is standing on a suspended floor, optimal result requires that at least the
pointed foot is above a supporting beam or close to a supporting wall.
ATTENTION
The pointed foot supporting the Logos 2N is very hard. It is designed to go through
carpeted flooring. If your floor is made of wood or tile, be careful not to scratch it by
moving the speaker without lifting the point.

ASSEMBLING THE LOGOS 1N WITH
LOGOS 2N
Lay out the frame elements on the floor with the base in its final location. There are four
adjustable feet located on the base, which support the frame.
Attach the Logos 2N (with its assembled long pointed bar) to the Logos-Frame using four
aluminum black spacers, four rounded head screws (M6x80) and four steel ring (∅ 18mm)
provided.
The spacer should be inserted between the frame and the speaker and the steel ring
should be placed between the screw and the frame (see page 13).
You may now stabilize the frame and Logos 2N assembly using the four adjustable feet
attached to the frame. If the floor surface is covered with thick carpet, the pointed bar may
not be long enough to pierce through to the hard surface below (essential for good
grounding). In this case, remove the pointed bar and insert a steel ring (∅ 18mm)
provided, between the bar and the Logos 2N enclosure to re-establish the bar as the
primary evacuation point.
Two people are required to lift the Logos 1N plus bar assembly into place. The lower point
of the Logos 1N bar is to be inserted into the screw-head located on the top of the Logos
2N. Have one person guide the bar into place without scratching the surface.
Once the Logos 1N is in position with the bar point resting in the screw-hole on top of the
Logos 2N, one person must hold the speaker in place whilst the other attaches the two
lateral arms to the sides of the speaker. For each side, use one long steel screw (M6x70),
two plastic rings, two gold serrated rollers, two teflon rings and one cylindrical serrated
roller (see page 11). Be careful not to drop the serrated roller onto the Logos 2N as this
could damage the surface. Do not over-tighten.

ASSEMBLING THE LOGOS 1N WITH
LOGOS 2N (Ctd.)
You can now attach the Logos 1N (with its assembled long pointed bar) to the LogosFrame using two aluminum black spacers, two rounded head screws (M6x70) and two
steel ring (∅ 18mm) provided. The spacer should be inserted between the frame and the
speaker and the steel ring should be placed between the screw and the frame (see page
13).
The assembly stage is now complete.

This action will avoid any loss and possible
damage of the parts.

LOGOS 1N-2N SPEAKER SYSTEM
LOCALISATION
In stereo, the ideal location of the speaker in the room has to be found by experiment.
Avoid standing the speakers in the corner of the room and try to set them away from any
adjacent wall by 60cm (2 feet) minimum. If the room size permits, try separating the
speakers by minimum 3m (10’) to provide a large stereo image.
To arrive to the listener simultaneously, the speaker should be aligned to be at an equal
distance from the listener position and each speaker - see the schematic below:

Right
25° - 30°

position
Depending on the room acoustics, the speakers may be standing parallel or slightly tilted
toward the listener.

CONNECTING THE BUILT-IN AMPLIFIER
The LOGOS 1N-2N SPEAKER SYSTEM inputs are unbalanced digital input (S/PDIF).
The LOGOS 1N-2N SPEAKER SYSTEM uses a full digital filtering, the crossover is made
by software inside the acoustic Processor, as a Metis 8, 10, Mimesis 15, 16.5, 32.5 with the
standard or personalized configuration file provided by the Goldmund Universal
Configurator.
The signal is treated with the Proteus technology and includes all its corrections. The
LOGOS 1N-2N SPEAKER SYSTEM has no active filtering (hardware crossover).
Only an official Goldmund representative is able to load and change the configuration file
into your acoustic processor, do not change it by yourself.
A wrong setting can damage the speakers; the warranty will not cover any factory change
without the approval of an official Goldmund representative.
ATTENTION
LOGOS 1N-2N SPEAKER SYSTEM can only work in association with a Goldmund
Acoustic Processor. In case you desire to use your system in a full Proteus correction, we
remind you that each speaker will need an output of the acoustic processor, a total of four
outputs will be needed to make a proper stereo system. For more details, contact your
Goldmund official representative.
Connect the digital cables to the digital input connector as per the Goldmund Universal
Configuration wiring schematic.
The LOGOS 1N-2N SPEAKER SYSTEM is automatically powered ON when they receive
modulation. When the digital input does not receive any data for 3 seconds, the speakers
are muted. They are de-muted as soon as a signal is present on the digital input and the
orange led will light up.
Main power must not to be removed while the LOGOS 1N-2N SPEAKER SYSTEM is not
muted (please wait 3 seconds after the music stops before removing the mains power).

RUNNING-IN THE LOGOS 1N-2N
SPEAKER SYSTEM
The LOGOS 1N-2N SPEAKER SYSTEM has been tested at the factory. However, like any
high quality speaker system, the Logos 1N2N needs several days playing music before
reaching the top sonic quality they are built for. The few first hours can be very frustrating
for a demanding listener.
Do not hesitate to let them play quite loud for some time before attempting any real system
tuning or position adjustment.

MAINTENANCE AND CLEANING
To clean the metal case of the speakers, you can use a clean, soft, damp cloth. Dampen
with water or a mild detergent solution. Avoid abrasive or harsh cleansers (e.g. Products
containing sodium carbonate).
The identification plate is plated with precious metal. Simply clean it with a soft cloth,
without any chemical solution.
