Thank you for purchasing the Goldmund PROLOGOS active speaker. Goldmund fully
incorporates the technological expertise developed by our company throughout many
years. Please take some time to read this manual. It will provide you with useful information
to make your pleasure of listening to the PROLOGOS speaker even higher.
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.

The PROLOGOS active speaker 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 the use of the best associated components,

The PROLOGOS active speaker requires special attention during unpacking, we
recommend two people for unpacking and installation of this unit, some handling steps
necessitate a lot of care.
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 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.

A rigid floor is very important for the optimal sonic result of your PROLOGOS.
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. The proper listening position is located by 1 to 1.5
times the distance between the speakers at equal distance from each. If the room size
permits, try separating the speakers by minimum 3m (10’) to provide a large stereo image.
In multi-channel system, it is recommended to put the speakers as close as possible to the
positions shown in the figure below:
Front-Left
25° - 30°
100° - 115°

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

The PROLOGOS has an event on the bottom base,
which must not be obstructed. To avoid operational
problems it is not recommended to put the speaker on
a flat base like on a bookshelf, see next chapter

Usable in any type of configuration, the PROLOGOS has built-in amplifiers with built-in
input crossovers. The input is an unbalanced digital input (S/PDIF).
When used with a digital input signal, 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.

To achieve optimal performance, please observe the following points:
•The PROLOGOS and the USB dongle or Wireless Transmitter should be placed in
the same room.
•There should be no metallic obstacles between the USB dongle or Wireless
Transmitter and the PROLOGOS, which could influence the wireless link.
•The computer with the USB dongle should not be moved around during playback.

The range of the wireless audio link depends on several factors, such as the amount of
WiFi equipment used in proximity of the PROLOGOS system, as well as the building
materials and the architecture of the room.
Depending on the above mentioned factors, the maximum range will normally be from 5 to
20 meters.
To use the PROLOGOS in wireless, follow these steps:
•Connect the speaker to a mains outlet using the power cords contained in the box.

•Connect the USB dongle to an USB port on your computer or the Wireless
Transmitter to the corresponding output channel of your acoustic processor.
•If you use the USB dongle: in your computer’s audio settings, select the USB
dongle as the audio output. If you use the Wireless Transmitter: contact your
Goldmund representative who will be able to load and change the configuration file
into your acoustic processor.
The system is now set up and ready to be used. The volume is set directly on the computer
(when used with the Dongle) or on the acoustic processor (when used with a Transmitter).
The PROLOGOS and the associated USB Goldmund dongle are delivered prepaired from
the factory. This means that your speakers can only function with the dongle that was
paired with it. However, if you would like to do a re-pairing of the speaker with the dongle
for any reason, please follow these steps:
- Connect the USB dongle to your computer or the Wireless Transmitter to your
acoustic processor.
- Insert a small screwdriver into the pairing hole located on the back panel of your
speaker, just above the input RCA.
- Gently press the internal pairing button using the screwdriver.
- As soon as the pairing is done, the led locking led will light up.
- The pairing is done.
In case you lose your dongle, you can order another one from your distributor who will also
pair it to your speakers.
The digital signal is treated with the Proteus technology. The PROLOGOS has no active
filtering (hardware crossover).
The PROLOGOS uses a full digital filtering, the crossover is made by software inside the
DSP speaker board.
Only an official Goldmund representative is able to load and change the configuration file,
do not change it by yourself.
Due to the high gain of the
PROLOGOS speaker, please make
sure that the media player is set to a
low output level, before connecting the
dongle to the computer.

A wrong setting can damage the speakers; the warranty will not cover any factory change
without the approval of an official Goldmund representative
The PROLOGOS is automatically powered ON when it receives modulation. When the
digital input does not receive any data for 3 seconds, the drivers 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 be removed while the PROLOGOS is not muted (please wait 3
seconds after the music stops before removing the mains power).
)
The PROLOGOS active speaker has been tested at the factory. However, as any high
quality speaker system, the PROLOGOS 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.
.
To clean the metal case of the speaker, 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.
