Danish Audiophile Loudspeaker Industries
DALI is a highly respected manufacturer
of loudspeakers for music lovers around
the world. The factory in Denmark controls
all facilities of the loudspekaer production,
including the development and design of
cabinets, crossover components and
custom drive units.
With firstclass equipment and know-how,
it is possible for DALI to develop and
produce loudspeakers according to the
highest subjective and technical standards, while maintaining close tolerance
limits.
DALI loudspeakers are developed subject
to a wide range of technical parameters
while never losing sight of the ultimate
goal: to create loudspeakers capable of
bringing all dimensions of music into your
livingroom.
With this manual DALI wishes to ensure
that you may enjoy the expertise and
quality invested in your loudspeakers.

UNPACKING
Most DALI models are delivered in pairs. The loudspeakers are typically marked (L)
left or (R) right. Place the loudspeakers to the left and to the right as seen from the
listening position.
The DALI R1000 however, are marked A or B. In this case please check the paragraph
about placement.
For the floor standing models spikes are included in the packing - please check this
before discarding the packing.
MAINTENANCE
Use a dry soft piece of cloth (or a wrung up soft piece of cloth with a mild detergent)
for wiping off the dust and grease from the loudspeakers cabinet. Please be careful
when cleaning the loudspeaker units because the diaphragms are very sensitive.
The grilles can be vacuum cleaned and if necessary wiped with a piece of wrung up
fluff-free cloth with a mild detergent.
BREAK-IN PERIOD
A loudspeaker is a mechanical device and
requires a break-in period. During the first
period of use you will therefore notice a
gradual improvement of the sound quality
of the loudspeakers.
Wear is not a problem for the DALI
loudspeakers. Actually, regular use will
only extend their life.
If the loudspeakers have not been used for
quite some time, they may need a short
break-in period again.

CONNECTIONS
Always switch off your amplifier/receiver before changing any connections. Always
use cables of the same type and of the same length for the left and right loudspeakers.
Always connect loudspeakers in the right side of the listening room to the output
terminals marked (R) or (Right) on the amplifier and loudspeakers in the left side of
the listening room to the output terminals marked (L) or (Left) on the amplifier.
Loudspeaker cables must always be
connected in phase between amplifier and
loudspeaker, that is from red plus (+) terminal
to red plus (+) terminal and from black minus
(-) terminal to black minus (-) terminal.
If not all loudspeakers are connected in phase
to the stereo or surround system, you will
experience weak bass and diffuse perspective.
Whether you are to connect two stereo
loudspeakers or a whole surround system you
must follow the same guidelines. In the diagram (fig. 1) it is shown how to connect a 5
channel surround system by using singlewiring (bi-wiring and bi-amping can be carried
out according to the directions below).
A stereo amplifier has two pairs of output
terminals called Right (R) and Left (L). You
connect the right (R) and left (L) loudspeakers
here. A surround amplifier also has outputs for
stereo loudspeakers typically called Front.
Furthermore, the surround amplifier has
outputs for Center and rear loudspeakers
Rear or Surround (fig. 1). Please check with
the manual for your surround amplifier.
Fig. 1
Tighten all connections so that cables do not get loose (do not use tools). No loose
strands of wires should stick out, as this may cause a short circuit and damage the
amplifier. Re-tighten the connections now and then as the connections may get loose
after a period of time.
Cable quality and construction does make a difference. Your should therefore always
buy cable of good quality to ensure the best possible sound quality.

Single-wiring
By single-wiring one cable is connected from
the amplifiers loudspeaker output to each
single loudspeaker.
On those loudspeaker models having two terminal pairs, the straps delivered with the
loudspeakers must be installed between the
upper and lower terminal pair: one between the
two red terminals and one between the two
black terminals of the loudspeaker (fig. 2).
With the straps installed, it is recommended that
you connect the cables from the amplifier to the
upper terminal pair.
Bi-wiring and bi-amping
DALI recommends that you use bi-wiring or biamping on the loudspeaker models having two
terminal pairs. Bi-wiring provides a more clean
and undistorted sound. Bi-amping offers an
even better improvement on these accounts as
well as extended dynamics.
Before using bi-wiring or bi-amping, the metal
straps must be removed. The lower terminal pair
is connected to the bass section and the upper
terminal pair is connected to the tweeter/
midrange section.
Fig. 2
Fig. 3
Bi-wiring
For bi-wiring (fig. 3) one cable is connected to
the lower terminal pair and another cable to the
upper teminal pair of the loudspeaker. These
two cables are connected to the same output
terminal on the amplifier.
Bi-amping
For bi-amping (fig. 4) two identical stereo power
amplifiers should be used. The output terminals
of one of the amplifiers are connected to the
lower terminal pair of the two loudspeakers and
the output terminals of the other amplifier are
connected to the upper terminal pair of the same
two loudspeakers.

PLACEMENT
Even the slightest changes of a loudspeakers placement in a room has big influence
on the sound. The spacious experience and the tonal balance will for instance be
effected by this. DALI therefore recommends that you experiment to find the optimum placement. Notice that your DALI loudspeakers should not be installed in places
where they are exposed to direct sunlight. In this connection, here are a few but
useful pieces about placement:
Avoid objects between loudspeakers and
listening position. Obstructions not letting the
sound pass through directly to the listener
may cause a wrong tonal balance and
influence the spacious experience negatively.
By critical listening the distance between left
(L) and right (R) front loudspeaker and
between each of the loudspeakers and the
central listening position should be the same
in order to optain the best posible spacious
reproducktion (fig. 5). DALIs Linear Directivity
construction principle ensures that the tonal
balance will be almost perfect, even when you
are not listening from a central position.
The loudspeaker models having a bass port
on the rear panel should always be placed
with free passage of air, otherwise, the bass
level is reduced.
Fig. 5
As a groundrule, DALI front loudspeakers
should not be angled towards the listening
position, as the loudspeakers with Linear
Directivity have been optimized for perfect horisontal frequency response. The use of
angling can only be recommended if the
loudspeakers have to be placed extremely far
from each other.
The center loudspeaker C1000 is especially
designed to be placed close to the large surface of the TV screen and you can freely
choose between a placement either over or
under the screen (fig. 6). The front of the
loudspeaker should be flush with the screen.
The rear loudspeaker R1000 is designed to
hang on a wall at a distance of minimum 1,5
meter above the floor (fig. 7).
6
Fig. 6
Page 7
A placement on the side wall and with R1000
placed somewhat behind the listening position is recommended (fig. 8).
tweeter unit in R1000 should be turned
towards the listening position. Please notice
that in case of side wall placement the R1000
marked A on the rear side label is meant for
the left rear channel and B for the right rear
channel (with rear wall placement this is the
other way around). This way you ensure an
angling towards the listening position.
The surround sound experience is ideal if the
loudspeakers are placed symmetrically around
a central listening position (fig. 7). Spacious
experience of the sound can definitely be present away from this central listening position.
However, it will be less accurate.
Spend some time setting up the surround
amplifier correctly with e.g. the correct level
in all channels. Surround amplifiers with
adjustment of delay times or distances
between listening position and loudspeakers
should be set up thoroughly by giving the
amplifier the exact informations. Follow the
guidelines from you amplifier manufacturer,
the process takes time but it pays off in form
of a perfect spacious sound scenario.

The stand/bookcase loudspeakers DALI Blue
1001 and 2002 should be placed and used in
accordance with the same principles as
mentioned above but we may add some pieces
of good advice:
In order to achieve the best possible spacious
reproduction, the loudspeakers should be
placed so that from the listening position you
can just see across the top plate. This can be
done by tilting the loudspeaker (fig. 9).
It is possible to place DALI Blue 1001 and
2002 high as e.g. in a bookcase, However, the
loudspeakers should then be turned with the
tweeter down towards the listening position in
order to utilize the built-in qualities handling
spacious reproduction (fig. 10). The DALI logo
on the front grille can be rotated so that it may
be read properly.

THE LISTENING ROOM
All listening rooms have their particular unique
acoustic properties which has a big influence on
how we experience the sound from the
loudspeakers. Basically, it has to do with the way
the room embraces the sound and then gets rid
of it again, and you can do something about that
yourself.
When loudspeakers are playing in a room, you
will not only hear the sound directly, but also a
number of reflections from the floor, walls and
the ceiling. These unwanted reflections can be
dampened by things in the room such as e.g.
book cases, plants, carpets, furniture etc.
If the sound is on the bright side, soft things such
as curtains, wall-to-wall carpets or spread carpets
can help. If the living room has big window
surfaces, closing the curtains can help.
The quality and amount of deep bass depends
on the size and shape of the room. The bass is
accentuated by placing the loudspeakers near a
side or a rear wall. A corner position normally
accentuates the bass even more, but it also
increases the reflections from the walls. You
should therefore experiment with different kinds
of placements in order to find the sound balance
you like best.
As a ground rule, you should avoid big, smooth
reflecting surfaces close to the loudspeakers, as
the reflections here will occur as phantom
loudspeakers and will in particular destroy the
spacious reproduction aspects. A plant, a wall
carpet, or just a carpet on the floor in front of the
loudspeakers can have a surprisingly big effect
on the experienced precision of the soundstage.
Once you have found the best position you
should make sure that the loudspeakers are standing firmly and do not rock. As for the floor standing models it is recommended that the spikes
delivered with the loudspeakers are mounted in
the bottom of the cabinet. On the stand/bookcase
models, attach the rubber feet included.

POWER AND SOUND PRESSURE LEVEL
A loudspeakers ability to play loud depends very much on the signal it has to
reproduce. It will therefore be practically impossible to define an unambiguous
maximum level so that the figure can be used in a sensible way.
In practice, however, you can say that a lot of pure, undistorted power from a big
amplifier is better than a distorted signal from a small amplifier pushed beyond its
limits. The signal from a distorting (clipping) amplifier contains far more high frequency
information than an undistorted signal, which puts a heavy strain on the tweeter unit.
More loudspeakers are therefore destroyed by small amplifiers working too hard
than by big amplifiers practically idling.
By turning the tone controls up beyond the
neutral position the strain on the loudspeakers
and amplifier is increased considerably. Tone
controls are meant for brushing up an old or a
poor recording. DALI strongly recommends that
you do not use these for compensating
weaknesses in other parts of the system. Repositioning the loudspeakers may be just what
it takes to achieve a much more musical result.
Under normal circumstances an overload of the
amplifier causes distortion (clipping) and
reduced clarity of the sound. If you make sure
never to turn up the volume beyond the point
where the music remains pure and undistorted,
usually you should experience no problems.
DYNAMICS
The focus is often solely put on how loud a loudspeaker can play, which is a pity
because some of the biggest experiences in music and movies sound are found in
the most quiet passages. Dynamics is the ability to reproduce these fine differences
very exact and then to explode in a turmoil of sounds without distortion.
DALI loudspeakers are able to reproduce these very fine details, partly because
DALI use specially developed Low Loss loudspeaker units.
A system with good dynamics can reproduce a true picture of the quality and size of
the music event, even at low levels.
Try listening at low levels. This can be a far more demanding test of the systems
ability than playing flat out at full power. Background noises from the surroundings
must of course be kept at an absolute minimum in order to experience the full dynamics
of the system.

USEFUL SPECIFICATIONS
A lot of more or less objective measurements of loudspeakers can be made.
Unfortunately the specifications stated are hardly ever comparable, and it is even
more rare that they tell you something about how the loudspeaker actually sounds.
DALI does not state the power handling of the loudspeakers, because this is a misleading and actually also not useable mesurement. Instead, DALI states sensitivity
and maximum sound pressure level.
A lot of people take it for granted that a 100 Watt loudspeaker can play louder than a
50 Watt loudspeaker. Maybe it can, but the reason is not that it can endure twice the
power. The difference is the sensitivity telling you how much of the output is actually
used for producing sound and how much for heat.
(It is like an electric bulb, where a 11Watt energy saving bulb glows with the same
intensity as a 60 Watt ordinary bulb.)
Always remember: it is the sound that matters, and the best way to evaluate it is by
using your ears.
