Introduction
Marten Philosophy
Congratulations! You are now the proud owner of a pair of Marten loudspeakers. At the
forefront of current designs, the Mingus Orchestra will reveal the full emotional range of
music with vivid dynamics and detail.
Properly installed, your Mingus Orchestra loudspeakers will give you many years of
listening pleasure. To realize the highest sound quality from your loudspeakers, some
important topics will be addressed in the following pages. By following these suggestions,
you will be able to enjoy sound that only Marten loudspeakers can deliver.
As a Marten loudspeaker owner, you are always welcome to come to our visitor’s centre,
where, in a relaxed environment, you can listen to our full range of loudspeakers.
Marten loudspeakers are extremely sensitive instruments and will give you many
enjoyable musical moments.
Marten loudspeakers create certain demands on the accompanying hi-fi equipment, the
burn-in process, and the placement of the speakers in the listening room. Even small
changes in any of these areas can change the sound considerably.
The sound and musicality of Marten loudspeakers depend upon such factors as your
choice of cables and source components. Even the quality of the recordings matters.
Marten loudspeakers will reproduce, in extremely high detail, the slightest imperfection in
recordings and in stereo systems.
The pure, present, detailed sound image and musicality of a Marten loudspeaker defines
the high end. Emphasis is not only put on great sound but on design as well. Marten
speakers are easily integrated into any living environment.

Unpacking
Quick Setup
When you receive your loudspeakers, you should make sure that the shipping box is in its
original state. If that is not the case, please contact your dealer.
Unpack the loudspeaker carefully, as there are several parts that can be damaged. We suggest
that you keep your box and inserts. You may need them for transporting your loudspeakers.
Make sure that each of your shipping boxes contains the following:
2 pcs Mingus Orchestra loudspeaker
8 pcs Marten IsoPucks
4 pcs terminal jumpers (for single wiring)
1 pcs Owner’s Manual
We recommend that at least two persons help each other in unpacking the loudspeakers.
• Take the lid o the crates close to the intended listening place.
• Tilt the shipping box up.
• Release the brakes on the wheels.
• Roll out the loudspeaker.
• Roll it to the intended placement.
• Remove the cloth material from the loudspeaker.
• Lock the wheels and change the wheels to Marten IsoPucks by tilting the loudspeaker.
Your Mingus Orchestra loudspeakers need quite a bit of playing time in order to reach
their maximum performance. The use of the burn-in CD enclosed with the Mingus
Orchestra loudspeakers is recommended to speed up this process. Follow these steps:
1. Connect the loudspeakers to your system.
2. Put the CD in your CD player.
3. Choose track 1 and set it on repeat
4. Set the volume to a moderate level
The CD should be played for a minimum of 24 hours before attempting to adjust the
loudspeaker placement. For more in-depth information about this process, please refer to
the section about burn-in.

Connecting the Loudspeakers
Choice of cable
Bi-wiring/bi-amping
Connections
To make the most of your Mingus Orchestra loudspeakers, please consider the
following suggestions:
The impact loudspeaker cables can have on the sound is dramatic. Be sure to use the same
brand, type, and length of cable on each channel. Mixing dierent types and/or lengths of
cable can upset the precise timing and balance of your loudspeaker.
The Mingus Orchestra is designed with bi-wiring in mind.
If you prefer bi-amping, we recommend that you use the same type of cable for the best
sound reproduction. For single-wire applications, please use the enclosed jumpers.
At the back of your Mingus Orchestra, you will find two pairs of WBT Nextgen terminals
that will accept any standard connection. Whatever type of connection you use, make
sure that the contact is tight, and have a proper contact area. Tighten the posts, and then
retighten aer a few days to make sure that the connections haven’t loosened.
Always turn o the power of your entire system before making connections to your
speakers. We recommend using an amplifier with su∏cient power (typically a
minimum of 40 watts).
In order to obtain the best localization of instruments and voices, as well as the deepest,
most natural bass, it is important to connect your loudspeakers in phase (which means
that the drivers are moving in and out in the same direction and at the same time). The
connectors on the speakers are clearly marked, and those on your amplifier and
speakers cables should be also be marked. Keep all markings consistent in order to
ensure in-phase connections.

Burn-in
Room Acoustics
The higher the quality of a loudspeaker system, the more demanding it will be regarding
burn-in time. Your newly unpacked Mingus Orchestra loudspeakers need quite a bit of
playing time to reach their optimum performance capability.
We have enclosed a CD to help speed up this process. Please allow the CD to be run for a
minimum of 24 hours before attempting to adjust the placement of the loudspeakers in
your listening room. Due to the high-tech materials used in the drivers, the Coltrane
Momento 2 will sound a bit harsh in the beginning, but aer 50 hours of playing your
loudspeakers will sound good.
Aer about 300 hours of playing, your system will be optimized. The sound will be more
open, detailed and display more natural musical warmth.
Compare the process to that of a fine musical instrument, which has to be played for a
period of time before reaching its full musical potential.
A good listening room has just the right amount of reflection and absorption. The
performance of any loudspeaker depends upon the speaker’s location in the room and
the acoustical conditions in that part of the room. Furnishings, size, and proportions all
eect tonal balance, imaging, and bass characteristics.
To test the sonic balance of your room, stand in the location where the speakers will be
installed and clap your hands two or three times. If the room is reverberant, you will hear
a sharpness or echo. If the room is dull, the sound of the clap will decay rapidly and there
will be little or no echo.
Large areas of glass, mirrors, or wood panelling will reflect sound waves and oen result
in brittleness and extreme brightness. You can correct this by breaking up these sound
waves with soer surfaces like draperies or wall hangings. Try to create random
reflections. Put a lot of time into the placement of the speakers. Experimenting with this
will be well worth the eort.

Positioning
Loudspeaker Placement
Distance to back and side walls
Focusing the Loudspeakers
Toe-in
Every room is shaped and decorated dierently, and is, therefore, presents unique
requirements for the positioning of loudspeakers. Your loudspeakers will function at their
best when placed on a flat, stable surface.
The space between the loudspeakers should be free. Ideally, the space should be
symmetrical in the area around the loudspeakers. We recommend experimenting with the
placement of your loudspeakers in order to obtain the best balance, openness, and
perception of depth.
For good results, the Mingus Orchestra should be no closer than 80 cm (31.5 Inch) from the
rear wall. Marten loudspeaker should not be placed close to a side wall, as reflections from
these can disturb the depth of the sound image.
The listening distance should not be closer than 3m, preferably 3.5m or further away.
Due to their highly advanced technology, the Mingus Orchestra loudspeakers will deliver
excellent imaging, even at a relatively close listening distance. The distance ultimately
depends on the room’s shape, size, and your listening taste. Please use track 2 of the
enclosed CD as a guide to focusing the sound image.
The goal is to have a balanced sound. Ideally, you should be able to place the recorded
voice in the middle of your speaker arrangement.
Ultimately, the shape, size, and furniture in the listening room all influence the end result,
so take some extra time to experiment with the position of the loudspeakers.
The loudspeakers should normally be toed in toward the listening area to focus the sound.
The amount of toe-in will depend upon your listening preferences and the room
environment and dimensions.

Marten loudspeakers requires no special treatment apart from the kind of handling you
would apply to any high-tech product in your home.
Because many dierent materials are used in the making of the loudspeakers, all-in-one
cleaning materials should not be used. Never apply abrasive/ aggressive cleaning fluids to
the outside of the unit.
The cabinet and other parts should only be cleaned with a so, dry or slightly damp cloth.
Do not attempt to open the unit’s case.
Refer all servicing to qualified service personnel.
In the event your Mingus Orchestra loudspeakers need to be serviced, please contact
your dealer, who will decide whether the problem can be remedied locally, or whether
to contact Marten for service.
