INTRODUCTION
GOLDMUND LOGOS 3N – ACTIVE SUB-BASS 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.

1 PRELIMINARIES
The Goldmund Logos 3N uses very innovative technology to achieve an unique level of
definition and neutrality in a sub-bass speaker system.
Please read very carefully the following instructions. This high-precision speaker is
extremely revealing and can provide the best effects only if it is used properly.
2 UNPACKING
The Logos 3N requires special attention during unpacking, the speaker is quite heavy, so
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 subwoofer 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 designed especially to protect the speaker in transit. Use of alternative
packaging will almost inevitably result in damage, which cannot be covered by the warranty.

3 LOGOS 3N LOCALISATION
For optimal sonic result, it is essential that vibrations arising within the Logos 3N be
evacuated to the ground effectively. Solid coupling with a very rigid floor is an essential
element in this process.
Preserve space around the speaker to provide proper cooling.
We recommend using the Logos 3N with the Logos 1N and Logos 2N in a Full Logos
Active System.
4 CONNECTING THE BUILT-IN AMPLIFIER
The Logos 3N input is an unbalanced digital input (S/PDIF). The S/PDIF digital signal
presents two channels (Left and Right). By default the channel left is set from factory.
The Logos 3N uses a full digital filtering, the filters are made by software inside the acoustic
processor (Metis 8, 10, Mimesis 15, 16/16HD, 32) with the standard or personalized
configuration file provided by the Goldmund Universal Configurator.
The signal is treated with the Proteus technology with all its corrections. The Logos 3N has
no active filtering (hardware filter).
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 The Logos 3N can only work in association with a Goldmund Acoustic
Processor: Metis 8, Metis 10, Mimesis 15, Mimesis 16/16HD, and Mimesis 32.

CONNECTING THE BUILT-IN AMPLIFIER (Ctd)
The digital filter is carried out inside the acoustic processor.
Connect the digital cable to the digital input connector. Since a digital Spdif cable carries 2
channels, you may link the digital output to the next speaker to transfer the second channel.
The Logos 3N is automatically powered ON when it receives modulation. When the digital
input does not receive any data for 3 seconds, the subwoofer is muted. It is 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 3N is not muted (please wait 3
seconds after the music stops before removing the mains power).
5 RUNNING-IN THE LOGOS 3N
The Logos 3N has been tested at the factory. However, as any high quality speaker
system, the Logos 3N 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.
