Precautions
Please read this user manual carefully and pay special attention to the following precautions and
warnings.
____________________________________________ Safety Precautions
Ensure without fail that your new PIEGA
loudspeakers are mounted, positioned and
connected exactly according to these instructions.
PIEGA loudspeakers were only designed for use in
dry residential environments within a temperature
range of 10...40°C.
The high quality loudspeaker chassis of PIEGA
loudspeakers contain exceptionally strong magnets
with magnetic fields that may impair the operation
of other devices if the loudspeakers are not
handled properly.
Ensure that watches or other metallic objects are
not placed close to the loudspeakers. The strong
magnetic fields may pull these into the diaphragms
and destroy them.
Keep items such as credit cards, electronic data
storage media and similar objects away from the
loudspeakers. The magnetic field may cause
irrecoverable loss of data.
Warning
Ensure, in particular with children, that hands are
not placed inside the bass tube openings (sharp
edges Ærisk of injury) and that objects are not
inserted into these openings.

Unpacking the Loudspeakers
Special care was taken in the packaging of your new PIEGA quality products in order to ensure that
your loudspeakers reach your living room safely and undamaged. In order to avoid any damage when
unpacking the loudspeakers, follow closely the instructions below without fail.
____________________________________________ Procedure
In order to avoid any damage when unpacking the
loudspeakers or during the installation, you should
always carry out the work with another person.
Before unpacking, remove any jewelry such as
watches, rings, bracelets etc. in order to avoid
scratching the aluminum surface.
Open the carton (fig. 1), remove the metal
brackets on the carton carefully (fig. 2)
Lift out the protective cushions (fig. 3), put the
carton upright (fig. 4) in the way the marking of the
carton faces upwards. Lift out carefully the
loudspeakers and protective cushions (fig. 5).
Check without fail that the delivery is complete,
that the loudspeaker version supplied corresponds
to your order, and that the loudspeakers have not
been damaged in transit.
If this is the case, follow the instructions on the
remaining pages or otherwise contact the dealer
where you purchased the loudspeakers.
Warning
PIEGA loudspeakers have cabinets made from
polished aluminum. When unpacking, handle
carefully at all times!

Positioning and Connecting the Loudspeakers
Perfect sound quality depends on the correct positioning and alignment of the loudspeakers. For
stereo operation, the best results are achieved using the <<stereo triangle>> layout. The MasterONE
should be positioned as described below.
________________________________________ Positioning
The distances between the loudspeakers and the
point of listening form an isosceles triangle, Ratio
1 : 1.5, (e.g. two meters distance between the
speakers and three meters distance to the
listening position/stereo triangle)
Turn the speakers approximately 10° inward
towards the desired point of listening
Position in as clear a space as possible with
clearance at the back and the sides
Recommended wall distance min. 50 cm
To isolate your loudspeakers from the floor, please
use spikes or pucks with a similar effect.
________________________________________ Connecting the Loudspeakers
Ensure that the electronic components are
switched off before making the connection.
The PIEGA MasterONE should be run with a
sufficiently powerful amplifier with a good sound
quality.
Contact your dealer if you are unsure whether the
amplifier is powerful enough.
Ideally, use the OPUS 1 loudspeaker cable
(optional) as this is optimized to the sound of
PIEGAs coaxial system.
Ensure the poles are connected correctly: The plus
pole of the loudspeaker (red socket) must be
connected with the plus pole of the
amplifier/control system, the minus pole of the
loudspeaker (black socket) must be connected
with the minus pole of the amplifier/control
system.

PIEGA – Room adjustment
The rocker switch provided at the back of the housing enables you to optimally adjust the MasterONE
to the acoustics of the room it is placed in. Starting from position N = Normal, the PIEGA room
adjustment feature allows you to adjust the level for the bass, midrange and treble. Ensure that the
controller settings on both loudspeakers are the same.
_________________________________________ Room adjustment
The three rocker switches at the back of the bass
housing (viewed from the back) have the
following functions:
First switch on the left Bass range:
Up position = Normal position
Down position = Bass signal reduced. This
position should be selected if the room tends to
produce a “drone effect” and the sound is too
bassy.
Second switch in the middle Midrange:
Up position = Normal position
Middle position = Midrange reduced by 2dB.
This position must be selected if the room is
reverberant and has little damping and / or the
listening distance to the loudspeakers is less than
2 meters.
Down position = Midrange raised by 2dB. This
position must be selected if the room is severely
damped.
Third switch on the right Treble range:
Up position = Normal position
Middle position = Treble reduced by 2 dB. This
position must be selected if the room is
reverberant and has little damping and / or the
listening distance to the loudspeakers is less than
2 meters.
Down position = Midrange raised by 2dB. This
position must be selected if the room is severely
dampened and the listening distance to the
loudspeakers is less than 5 meters.
These recommended settings offer excellent
results in most rooms. However, other settings
that are different to these recommendations may
be ideal depending on the acoustics of the room
and personal taste. Test the different possibilities
or contact PIEGA customer service for further
questions.

Running in the Loudspeakers
After production, the MasterONE is subjected to a rigorous measurement and listening tests.
As a loudspeaker is basically a mechanical transducer consisting of several different components, the
individual elements must be run in during the initial weeks. This will ensure that the sound quality
potential of your loudspeakers is fully utilized. You will definitely notice the resulting improvement in
sound.
_____________________________________________ Recommendations
In the first days and weeks listen only at normal
volume.
Avoid very high volume levels during initial phase.
Listen to a wide range of programme material.
_____________________________________________ Limit range
The recommended amplifier output is up to 250
Watt. It must be ensured that the volume must
only be turned up far enough for the ear to register
an overload.
If the loudspeaker chassis become damaged after
a long period of overload, this can be detected
beyond any doubt by PIEGA service technicians. In
these cases, PIEGA is not liable for any warranty
claims.
_____________________________________________ Note
Excessively loud music can damage your health.
Listen to music at an acceptable volume level for
the sake of your health.

Daily Use
From development to production, right down to quality testing, PIEGA only uses materials and
components of the highest quality. Your new PIEGA loudspeakers are provided with a polished
aluminum surface. Although this material is not very sensitive, it should be treated with due care.
_________________________________________ Care instructions
Clean the surfaces of the PIEGA loudspeakers
with a soft, fluff-free cloth. If necessary use a
soft cloth sprayed with a little mild window
cleaner. A soft, fluff-free cloth that is slightly
moistened is ideal for cleaning the wrinkle
finish. Modern fine quality microfiber cloth is
particularly suitable.
Never use solvents to clean your PIEGA
loudspeakers
Never use abrasive detergents or any agents with
abrasive ingredients
_________________________________________ Warnings
Do not remove the front cover
To avoid damage, take great care when children
are close to the loudspeakers
_________________________________________ Attention
On no account touch the tweeter- or midrange
foil of your loudspeaker.
