Welcome Thank you for choosing Mingus Orchestra.
We’ve spent years engineering the sound of t
his loudspeaker to oer true musicality.
Mingus Orchestra presents a balance of intuitive
design and technological expertise. The result is
music as it should be, with vivid dynamics and a
detailed sound stage.
Our aim has always been to recreate sound as it
was recorded - bringing you closer to the live energy
and spirit of music.
For this level of detail, it’s important to ensure
that your system is of equal match to your
loudspeakers. Your amplifier, source components,
cables and even recordings can aect the sound of
Mingus Orchestra.
It’s vital to set-up your loudspeakers correctly
and adjust them to your listening environment.
There are many factors to think about, but
careful consideration at this stage will ensure
optimum performance that you can enjoy for
many years to come.

Unpacking
Contents
How to unpack
2 x Mingus Orchestra loudspeaker
8 x Marten Isolators
4 x Terminal jumpers (for single wiring)
1 x Owner’s manual
1 x CD / USB
Unpack your loudspeakers carefully, as there are sensitive parts
that could be damaged. We suggest that you keep the box and
inserts for later transportation of your loudspeakers.
Mingus Orchestra is packed in 2 black flight cases.
Please check the contents when you receive
your loudspeakers. If the shipping box does not
arrive in its original state, please contact your
dealer immediately.
We recommend that at least two people unpack and
assemble the loudspeakers.
1. Take the lid o the crates close to the intended listening position
2. Tilt the shipping box up
3. Fold out the ramp
4. Release the brakes on the wheels
5. Roll out the loudspeaker using the ramp
6. Remove the cloth cover from the loudspeaker
7. Move the loudspeaker to its intended listening position
8. Lock the brakes on the wheels
9. Change the wheels to Marten Isolators
9.1 Li right-side of speaker
9.2 Unscrew both wheels
9.3 Screw Isolators into the stand as far as possible without
over-tightening
9.4 Lower the speaker
9.5 Repeat steps 9.1 - 9.4 for the le-side of the speaker
9.6 Adjust each Marten Isolator to ensure the speaker is level
9.7 Rotate each Marten Isolator so the Marten logo faces
forwards
9.8 Tighten nuts to fix the position of each Marten Isolator

Initial setup
Burning-in your loudspeakers
Your newly unpacked Mingus Orchestra
loudspeakers need considerable playing time in
order to reach their optimum performance.
1. Connect the loudspeakers to your system
2. Put the CD in your CD player or use the files on the USB drive
3. Choose track 1 and set it on repeat
4. Set the volume to a moderate level
We recommended the use of the burn-in track (CD/USB) to
speed up this process. Due to the high-tech materials used in the
drivers, Mingus Orchestra may sound a bit harsh at first. Aer
approximately 50 hours of playing your loudspeakers will sound
much better. Aer about 200 hours of playing, your system will
be optimised; the sound will be more open, detailed and display
more natural musical warmth.
Please allow the audio to run for a minimum of 24 hours
before adjusting the placement of the loudspeakers in your
listening room.

Connecting your
loudspeakers
Wiring method
Connections
Choosing cables
To get the most of Mingus Orchestra please
consider the following when connecting them
to your system.
The cables you use can have a dramatic eect on the sound of
your loudspeakers. Be sure to use the same brand, type and
length of cable for each channel. Mixing dierent types and/or
lengths of cable can upset the precise timing and balance of
your loudspeakers.
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.
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.
On the back of each Mingus Orchestra cabinet, you will find
two pairs of WBT Nextgen terminals that will accept any
standard connections.
In order to obtain the best localisation of instruments and
voices, as well as deep, natural bass, it is important to connect
your loudspeakers in-phase. The connectors on the speakers are
clearly marked with + (red) and - (white) symbols. Your amplifier
and loudspeaker cables should also be clearly marked. Keep all
markings consistent to ensure in-phase connections.
It is important to make sure that contact to the terminals is
good and the connectors are tight. Tighten the terminal posts
and then, aer a few days, retighten to make sure that the
connections haven’t become loose.

Room acoustics A good listening room has just the right amount
of reflection and absorption.
The performance of any loudspeaker depends on the speaker’s
location in the room and the acoustic conditions in that part of
the room. Furnishings, size and proportions all aect tonal
balance, imaging and bass characteristics. Large areas of glass,
mirror, or wood panelling will reflect sound waves and oen
result in brittleness and extreme brightness. You can correct this
by breaking up these sound waves with soer surfaces like
curtains or wall hangings - try to create random reflections.
Allow time to experiment with the placement of your speakers
- eort at this stage will reward you with good sound
optimisation in your room.

Positioning
Rear and side walls

Focusing your loudspeakers
Loudspeaker placement
Every room is shaped and decorated dierently
and therefore presents unique requirements for
the positioning of loudspeakers.
Your loudspeakers will function at their best when placed on a
flat, stable surface. Ideally, the space between the loudspeakers
should be clear and the speakers should be centred on the rear
wall. We recommend experimenting with the placement of your
loudspeakers in order to obtain the best balance, openness and
perception of depth.
For the best results, Mingus Orchestra should be no closer than
80 cm (31.5”) from the rear wall. Marten loudspeakers 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 be no closer than 3m, but
preferably 3.5m or greater.
On the back of each Mingus Orchestra loudspeaker, you will find
a dial that will allow you to adjust the bass by 1 dB in four steps.
Rotating the knob clockwise increases the sensitivity, and
rotating it anti-clockwise decreases the sensitivity.
Mingus Orchestra loudspeakers deliver excellent imaging.
To make the most of this, the loudspeakers should be toed in
towards the listening area to focus the sound.
Ideally, your listening position and each loudspeaker
should form an equilateral triangle. The goal is to have a
balanced sound. Track 2 of the enclosed CD / USB can be
used to help focus the soundstage. With this track, you
should be able to place the recorded voice in the centre of
your speaker arrangement.
The amount of toe-in will depend on the room environment and
dimensions, as well as your listening preferences. Take time to
experiment with your listening position and the position of your
loudspeakers. This will give you a more precise sound image.

Enclosed CD / USB
Care of your loudspeakers
The enclosed CD and USB contains tracks to help you
set up your loudspeakers. There are also three tracks
purely for your listening pleasure; these were
recorded in our studio in Gothenburg, Sweden.
You can also download these files from marten.se/audiofiles
Marten loudspeakers require no special treatment
apart from careful handling, as you would with any
high-tech product in your home.
1. Burn-in track*
2. The Look Of Love** - Jeanette Lindström & Steve Dobrogosz
3. Blue In Green - Tommy Kotter
4. I Can’t Believe He Never Said Goodbye - Åsa Tåhlin, Mitch
Hiller & Peter Axelsson
5. Lady’s A Tramp - Mitch Hiller & Peter Axelsson
Because many dierent materials are used in the making of the
loudspeakers, all-in-one cleaning materials should not be used.
Never use abrasive materials or cleaning fluids.
The cabinet and other parts should only be cleaned with a so,
dry cloth or one slightly dampened with water.
* Use to burn-in your loudspeakers
