Observe all warnings on the equipment itself.

To avoid electrical shock, do not open the

enclosure or remove the amplifier from the rear

panel. There are no user serviceable parts

inside. Refer all service questions to an

authorised B&W dealer.

To prevent electric shock, do not use this

(polarised) power plug with an extension cord

receptacle or other outlet unless the blades can

be fully inserted to prevent blade exposure.

Ensure that the voltage indicated on the amplifier

panel matches that of the power supply.

The mains fuse holder is located on the back

panel of the amplifier module. Replacement fuse

must be of the same type and rating as supplied.

An earth (ground) connection is provided in the

mains input socket. However, the equipment is

double insulated and will operate safely without

being earthed (grounded), but may suffer

increased levels of hum breakthrough.

To ensure adequate cooling of the amplifier,

operate the equipment only with the heatsink

fins aligned vertically.

Check that there are no cables under the carpet

that may be damaged by the spikes.

Do not walk the unit on the spikes as this may

cause them to become detached from the

cabinet and cause damage.

Take care not to impale your feet with the spikes.

INTRODUCTION

Thank you for choosing B&W.

The DM

™

605 S2 consists of passive midrange

and tweeter sections together with an active

bass section powered by an internal 130 watt

amplifier. This enables the system to function

as a combined full range loudspeaker and

subwoofer, allowing the user to save space in

a home theatre installation by avoiding the

need for a separate subwoofer unit.

Please read this manual fully before unpacking

and installing the product. It will help you to

optimise its performance. As the loudspeaker

is mains powered, you should pay particular

attention to the safety warnings.

B&W maintains a network of dedicated

distributors in over 60 countries who will be able

to help you should you have any problems your

dealer cannot resolve.

UNPACKING

(figure 1)

• Fold the carton flaps right back and invert

the carton and contents.

• Lift the carton clear of the contents.

• Remove the inner packing from the product.

We suggest you retain the packing for future use.

Check in the carton for:

• 4 spike feet with lock nuts.

• Mains power lead

POSITIONING

Do not fit the spike feet until you have found the

best position for your speakers.

Stray magnetic ﬁelds

The speaker drive units create stray magnetic

fields that extend beyond the boundaries

of the cabinet. We recommend you keep

magnetically sensitive articles (television and

computer screens, computer discs, audio and

video tapes, swipe cards and the like) at least

0.5m from the speaker.

Stereo Audio

(figure 2)

As an initial guide:

• Position the speakers and the centre of the

listening area approximately at the corners of

an equilateral triangle.

• Keep the speakers at least 1.5m apart to

maintain left-right separation.

• Keep the speaker baffles at least 0.5m clear

of walls.

Home Theatre

(figure 3)

If used for front left and right channels, place the

speakers between 0.5m and 1m from each side

of the screen. If used as surround speakers,

place them to left and right and behind the

listeners. Because the speaker is not magnetically

shielded, it is only suitable for centre channel use

if you are using a projector TV. In that case it

may be placed directly below the centre of the

screen if there is sufficient room.

CONNECTIONS

All connections should be made with the

equipment switched off.

Full range input

(figure 4)

There are 2 pairs of terminals at the back of

the speaker which permit bi-wiring if desired.

On delivery, the separate pairs are connected

together with high-quality links for use with a

single 2-core cable. For single cable connection,

leave the links in place and use either pair of

terminals on the speaker.(figure 4a)

Ensure the positive terminal on the speaker

(marked + and coloured red) is connected to

the positive output terminal of the amplifier and

negative (marked – and coloured black) to

negative. Incorrect connection can result in

poor imaging and loss of bass.

To bi-wire, remove the links by loosening the

terminal caps and use a separate 2-core cable

from the amplifier to each pair of terminals

(figure 4b). This can improve the resolution of

low-level detail. Observe the correct polarity as

before. When bi-wiring, incorrect connection

can also impair the frequency response.

Ask your dealer for advice when choosing

cable. Keep the total impedance below the

maximum recommended in the specification and

use a low-inductance cable to avoid attenuation

of the highest frequencies.

Low-frequency effects (LFE) input

(figure 5)

The LFE or subwoofer output of your decoder is

connected to the LFE input of one of the speakers

using line level coaxial cable terminated by an

RCA Phono plug. Connect the second speaker

LFE input socket to the LFE link out socket of the

first speaker.

Connection to the mains power supply

Ensure that the voltage indicated on the amplifier

panel matches that of the power supply. Should

you need to change the setting, perhaps

because you have moved to an area having a

different supply voltage, slide the voltage

selector switch to the other position WHILE THE

SPEAKER IS DISCONNECTED FROM THE

MAINS POWER SUPPLY.

A 3-core mains power lead appropriate to the

country of sale is supplied that fits the IEC mains

input socket (figure 6A) in the amplifier panel.

The same value mains fuse is used whatever the

supply voltage and it is fitted in a tray at the

bottom of the mains input socket (figure 6B).

REPLACEMENT FUSES MUST ALWAYS BE OF

THE SAME TYPE AND RATING AS ORIGINALLY

SUPPLIED.

The speaker features auto-sensing of the input

signal to switch it between the standby and fully

on modes. This feature only operates if the

AUTO SENSE switch (figure 6C) is set to ON.

On first connecting the speaker and turning the

POWER switch ON, the initial surge is enough

to turn the amplifier fully on and the LED

(figure 7) near the logo at the bottom of the front

panel glows green. If no signal is detected after

a period of approximately 5 minutes, the

amplifier switches automatically to standby and

the LED glows red. In this mode the power

consumption is approximately 4 watts. If a

signal is detected at the input to the speaker,

the amplifier automatically switches fully on

within 0.5 seconds.

FINE TUNING

Before fine tuning, double check that all the

connections in the installation are correct

and secure.

Moving the speakers further from the walls will

reduce the general level of bass. Space behind

the speakers also helps to create an impression

of depth. Conversely, moving the speakers closer

to the walls will increase the level of bass.

If the bass is uneven with frequency it is usually

due to the excitation of resonance modes in the

room. Even small changes in the position of the

speakers or the listeners can have a profound

effect on how these resonances affect the sound.

Try mounting the speakers along a different wall.

Even moving large pieces of furniture can have

an effect.

If the central image is poor, try moving the

speakers closer together or toeing them in so

they point at or just in front of the listeners.

(figure 8)

If the sound is too harsh, increase the amount

of soft furnishing in the room (for example use

heavier curtains), or reduce it if the sound is dull

and lifeless.

Test for flutter echoes by clapping your hands

and listening for rapid repetitions. Reduce them

by the use of irregular shaped surfaces such as

bookshelves and large pieces of furniture.

Ensure the speakers stand firmly on the floor.

Whenever possible fit the spike feet supplied

after you have optimised the positioning. They

are designed to pierce through carpeting to the

floor surface. Initially, screw the lock nuts fully

onto the spikes and screw the spikes fully into

the threaded inserts in the base of the speaker.

If the cabinet rocks, unscrew the appropriate

spikes until the speaker stands firmly on the floor

and lock them in place by tightening the lock

nuts against the base. If you do not have a

carpet, use a protective disc under the spikes to

protect the floor surface.

If you want to raise or lower the bass level

with respect to the midrange and tweeter level,

change the setting of the LEVEL control

(figure 6D) on the amplifier panel. The control

is calibrated in dB relative to the ‘0’ position,

which equates to a flat free-field response.

(figure 9)

The equalisation (EQ) control (figure 6E) modifies

the bass cut-off frequency and roll-off rate.

Position ‘F’ corresponds to the maximum output

and gives a 6th-order Butterworth (maximally flat)

anechoic response with a -3dB frequency of

25Hz. However, most rooms give some degree

of boost to the bass frequencies and a better

balance may be found at one of the other

settings. Figure 10 shows how the control affects

the system response. The more gradual the roll-

off rate, the tighter the bass will sound.

Reducing the bass level or extension may allow

the overall speaker to play louder without

distortion, from either speaker overload or

clipping of the amplifier output.

The polarity of the LFE (subwoofer) signal can be

reversed using the PHASE switch (figure 6F) if

necessary. Normally the switch will be set to 0°

(non-inverting). However, some amplifiers invert

the signal between input and output and, if you

are using such an amplifier to feed the full range

part of the speaker, you should set the switch to

180° (inverting), otherwise you will suffer a loss

of bass through cancellation.

For greatest realism in home theatre installations

it is important to balance the speakers and

adjust the acoustic image to match the size of

the screen. With smaller screens it may be more

realistic to have the left and right speakers closer

together than you might for audio alone.

Adjust the levels of the three front speakers to get

a smooth transition of sounds as they pan across

the screen. Adjust the level of the surround

speakers so that, except for special effects, your

attention is not unduly attracted to them.

Sit in all likely listening positions when deciding

on the optimum levels.

Consult your decoder manual for further

information on how to set the levels.

AFTERCARE

The cabinet surface usually only requires dusting.

If you wish to use an aerosol cleaner, remove the

grille first by gently pulling it away from the

cabinet. Spray onto the cleaning cloth, not

directly onto the cabinet. The grille fabric may

be cleaned with a normal clothes brush whilst

the grille is detached from the cabinet.

Avoid touching the drive unit diaphragms,

especially the tweeter, as damage may result.

raccord électrique.

Assurez-vous, en premier lieu, que la tension

indiquée sur l’appareil correspond bien a celle

de votre réseau électrique.

Les fusibles d’alimentation se trouvent sur le

panneau du module d’amplification. En cas

de remplacement, n’utilisez jamais de fusibles

d’un type différent ; vérifiez que les valeurs

indiquées sur les nouveaux fusibles sont

parfaitement identiques à celles qui figurent sur

les modèles d’origine.

Une borne de mise à la terre est incluse à

l’embase de raccordement au réseau électrique.

Cependant, le matériel est construit avec un

double isolement et peut fonctionner en toute

sécurité sans raccordement à la terre. Le seul

risque peut être une élévation du bruit de fond.

Pour assurer une ventilation suffisante à

l’amplificateur, les ailettes des radiateurs de

refroidissement doivent être orientées en

position verticale.

Contrôlez que les câbles ne risquent pas d’être

transpercés par les pointes de découplage.

Ne déplacez pas l’appareil en le faisant glisser

sur ses pointes. Vous risquez de les arracher ou

de créer des dégats.

Prenez simplement garde de ne pas vous piquer.

DEBALLAGE

(figure 1)

• Repliez totalement les rabats du carton puis

retournez l’emballage avec son contenu.

• Soulevez le carton pour le vider de

son contenu.

• Retirez l’emballage intérieur.

Nous vous suggérons de conserver l’emballage

pour une utilisation ultérieure.

de blocage.

• Cordon d’alimentation électrique.

POSITIONNEMENT

Ne fixez pas les pointes avant d’avoir déterminé

la meilleure position de vos enceintes.

Champs magnétiques parasites

Les moteurs de haut-parleurs émettent un champ

magnétique parasite qui rayonne au-delà des

limites de l’enceinte acoustique. Nous vous

recommandons d’éloigner les appareils sensibles

à ce type de rayonnements (téléviseurs et

moniteurs informatiques, disquettes informatiques,

bandes magnétiques audio ou cassettes vidéo,

cartes à puces etc.) à plus de 0,5 m du coffret

de l’enceinte.

Ecoute en stéréophonie

(figure 2)

A titre indicatif :

• Disposez les enceintes acoustiques ainsi

que le centre de la zone d’écoute

approximativement aux trois angles d’un

triangle équilatéral.

• Ecartez vos enceintes d’au moins 1,5 m

pour obtenir une séparation gauche/droite

suffisante.

• N’approchez jamais vos enceintes à moins

de 0,5 m d’un mur.

Home Cinéma

(figure 3)

En utilisation comme enceintes avant gauche et

droite, placez les entre 0,5 et 1 mètre des bords

de l’écran. Utilisées comme enceintes

d’ambiance, elles seront disposées à gauche et à

droite et en arrière de la position d’écoute. Les

haut-parleurs n’étant pas blindés, vous ne pourrez

les employer comme voie centrale qu’avec un

projecteur vidéo. Dans ce cas, l’enceinte sera

installée directement derrière le centre de l’écran,

pourvu qu’il soit acoustiquement transparent et

que vous disposiez de la place nécessaire.
