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.

6 MAITENANCE AND CLEANING

To clean the metal case of the speaker, you can use a clean, soft, damp cloth. Dampen

without any chemical solution.
