OWNERS MANUAL

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 e uipment and know-how,

it is possible for DALI to develop and

produce loudspeakers according to the

highest subjective and technical stan-

dards, 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

uality 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 loudspeakers 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

re uires a break-in period. During the first

period of use you will therefore notice a

gradual improvement of the sound uality

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

uite 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.

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 uality and construction does make a difference. Your should therefore always

buy cable of good uality to ensure the best possible sound uality.

Fig. 1

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 dia-

gram (fig. 1) it is shown how to connect a 5

channel surround system by using single-

wiring (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.

Single-wiring

By single-wiring one cable is connected from

the amplifiers loudspeaker output to each

single loudspeaker.

On those loudspeaker models having two ter-

minal 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 bi-

amping 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.

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.

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). DALIs 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.

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 ho-

risontal fre uency 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 sur-

face 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).

PLACEMENT

Even the slightest changes of a loudspeakers 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 opti-

mum 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:

Fig. 7

Fig. 8

Fig. 9

Fig. 10

A placement on the side wall and with R1000

placed somewhat behind the listening posi-

tion is recommended (fig. 8).

The bottom

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 pre-

sent 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 ualities handling

spacious reproduction (fig. 10). The DALI logo

on the front grille can be rotated so that it may

be read properly.

All listening rooms have their particular uni ue

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 uality 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 stan-

ding firmly and do not rock. As for the floor stan-

ding 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.

THE LISTENING ROOM

POWER AND SOUND PRESSURE LEVEL

A loudspeakers 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 fre uency

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.

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 uiet 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 uality 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 systems

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.

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. Re-

positioning 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.

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 mis-

leading 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.
