Q Acoustics 2000i Series

Introduction

The Q Acoustics 2000i series is a range of loudspeakers designed to meet
the highest expectations of dedicated 2-channel audiophiles and
discerning movie enthusiasts. The range comprises:

2010i: Compact Bookshelf speaker with a 100 mm bass driver.
2020i: Bookshelf speaker with a 125 mm bass driver.
2050i: Floorstander with two 165 mm bass drivers
2000Ci: Centre channel with 2 x 100 mm bass drivers, which can be wall

mounted if required.
2070Si: 140 Watt active subwoofer with a 2 x 170 mm driver and signal

sensing for automatic power on/off.
The 2020i and 2050i speakers are both bi-wireable. All the loudspeakers

may be operated close to TV monitors with no ill-effects with the exception
of the 2070Si, which should not be operated within 500mm of TV screens
monitors or other magnetically sensitive equipment. Plasma and LCD
screens are unaffected.

Before making any connections to your loudspeakers make sure that all
active units in your system are switched off at the mains.

When switching on your sound system or changing input sources, set the
main volume control at a low level. Turn up the level gradually.

NEVER play your sound system at full volume. The position of the
volume control is deceptive and does not indicate the power level of the
system. Using very high volume settings may damage your hearing.

DO NOT connect your loudspeaker terminals to the mains supply.

DO NOT expose your loudspeakers to excessive cold, heat, humidity or
sunlight.

If you play your loudspeakers without their grilles on, be careful to protect
the drive units from damage.

DO NOT use makeshift stands. Fit the Q-Acoustics dedicated stand
according to the instructions and using any fixings provided. Your dealer
will advise you.

DO NOT dismantle the loudspeaker. You will invalidate the warranty.

Unpacking your loudspeakers

Unpack the speakers fully. Lift the speakers from the cartons by holding
the cabinets. Do not use the protective bags to lift them. The 2050i and
2070Si are heavy - get assistance to lift them if necessary.

When manoeuvring loudspeakers, do not drag them across the floor as
this may cause damage - lift them before moving them.

In the carton you will find: The loudspeaker/s and this product manual.

In addition the packing for the following models contains:

2050i: A set of floor spikes and spike covers for each speaker. An Allen
key to adjust the spikes once fitted.

2070Si: A power cord suitable for the mains supply in your area,
2 x Right angled RCA / Phono cables and an AV Setup CD.
Check the product carefully. If any items are damaged or missing, report

this to your dealer as soon as possible.
Retain the packing for future transport. If you dispose of the packing,

please do so following all recycling regulations in your area.

Preparation

Spikes are sharp. Exercise care!
Never place a spiked loudspeaker where it can cause damage!
Always move your loudspeakers by lifting them - never drag them!

Fitting the Floorstand Spikes - 2050i Foam Bung

floor push a spike protector over each
spike before turning the speaker
upright) When the speaker is the right
way up, insert the Allen key into each
spike from the top and adjust all the
spik es in and out un t il the
loudspeaker is level and stable.

The 2070Si subwoofer bass is adjusted using the level controls.

Ensure the bungs are fitted snugly into the port without inserting them too
far. You will find the level of bass is reduced but definition and bass
extension is increased. Experiment to see what you prefer and try making
small changes to the position of the speaker to optimise the final result.

Positioning Passive Loudspeakers

2050i

The 2050i loudspeakers should be positioned at least 200mm from a
back wall and 500mm from the side walls. Placing the speakers closer to
the wall will increase bass but could cause the sound to boom and lack
precision and detail. The speakers should be 2m - 4m apart and central
to the seated listener. Turning the speakers slightly inwards will sharpen a
stereo image but may cause narrowing of the sound source.

2010i and 2020i

The 2010i and 2020i are ideally mounted on Q-Acoustics floor stands or
wall mounted. If you are stand mounting, a simple guide is that the treble
unit should be at ear level to a seated listener. Wall mounted speakers
may be mounted slighter higher with the speaker angled down. Stand
mounted speakers should be treated as floorstanding speakers except
that the speaker may be placed a little closer to the back wall. Shelf
mounting is also possible.

Dolby and the double-D symbol are
trade marks of Dolby Laboratories.

An optional bracket designed specifically to wall mount the Q Acoustics
2010i, 2020i and 2000Ci is available from your dealer. Floor stands for the
2010i and 2020i are also available.

Be prepared to experiment to find the best setup for your taste in your
particular listening room.

Effects loudspeakers

2000Ci

The 2000Ci is designed to be operated close to a TV screen and central
to it. It should be placed immediately above or below the screen. If you
are using a regular TV set, make sure that the TV is capable of adequately
supporting the speaker and has a level top. If not, consider placing the TV
on a cabinet with the 2000Ci on a secure shelf immediately below the TV.

If you have a Plasma or LCD monitor, mount the 2000Ci to the wall or
other suitable surface immediately above or below
the screen using the Q-Acoustics Wall Bracket.

Surround Speakers

There are recommendations from Dolby labs for

5.1 effects speakers.
Surround speakers should be mounted on either

side of the listener, slightly behind the listening
position. The speakers should be sited facing
inward either mounted on the side walls of the
room or if the room is large, on high stands and
with their centres above ear level to a seated
listener.

Preliminaries

Unpack the subwoofer following the guidelines given earlier. Before
connecting the subwoofer please make sure that all the electronics in
your system are switched off at the mains.

The subwoofer is set to the voltage in your area. If you move to an area
with a different voltage, be sure to set the voltage selector to the right
setting before connection to the mains supply!

Positioning the Subwoofer

Bass frequencies are substantially omni directional. Although this means
that you can position the subwoofer almost anywhere, the stereo image
will still benefit by positioning the subwoofer level with the front
loudspeakers and as central to the listening position as possible. This
may not be feasible in a multichannel system. If you place the subwoofer
close to a wall the bass will be re-enforced therefore in some locations
the bass may be boomy and indistinct.

The subwoofer should be positioned close to a mains power source. Do
not use extension cables. Purchase a longer power cord if necessary.

The MAINS ON/OFF switch is the means of disconnecting this apparatus
from the mains and is mounted on the rear panel. There should be ample
free space between the rear of the cabinet and any wall or other object to
allow free unrestricted access to this switch.

When positioning the subwoofer ensure the floor is sound with no loose
floorboards etc. The air movement from the subwoofer at high volumes is
substantial - do not place it close to soft furnishings or objects that may
rattle. Do not place objects of any kind on the unit.

2070Si Subwoofer - Operation

Setting Up and Use

Auto Power On: This feature enables you to switch the main system on

and off without having to remember to switch the subwoofer on and off as
well.

If there is no signal input, after a few minutes the subwoofer will
automatically power down into Standby mode. This is indicated by the
POWER light on the rear panel changing to red. As soon as the
subwoofer senses an input it will automatically switch into operational
mode and the power light will again glow green. Some types of music
and some TV channels have very little low frequency information in the
audio signal in which case the subwoofer may not automatically switch
out of standby even though sound is coming from the other speakers in
the system. If this happens then the threshold can be adjusted to make
the unit more sensitive by setting the auto-on sensitivity to HIGH. Under
some circumstances however this setting may make the sub-woofer stay
on at all times, this is due to the small amount of noise which will normally
be present from the main system amplifier. This noise should disappear
when the amplifier is set to standby, thus allowing the subwoofer to turn
off again. If the sub-woofer remains on even when the main amplifier is
turned off then we recommend you leave the sensitivity switch at MED,
the loss of bass will be almost undetectable due to the characteristic
response of human ears.

If the level of noise produced by the amplifier is higher than normal, or the
connection cables are picking up hum from nearby power cables, the
sub-woofer may remain on even when no sound is playing. If hum is
noticeable from the subwoofer then you should try moving the cables to
reduce the hum pick-up or try a different cable/s. In circumstances where

the problem cannot be easily remedied we recommend trying the LOW
setting of the sensitivity switch to see if that allows the sub-woofer to enter
standby.

Although the subwoofer can be safely left in standby mode indefinitely, if
you are going to be absent from home for a long period, we advise that
the unit is switched off at the ON/OFF switch.

The 2070Si Subwoofer also has a fail safe heat protection system. If the
amplifier overheats it will shut down momentarily and then resume
operation. If this occurs check that the ventilation holes on the control
panel are not covered and that the sub-woofer is not placed too close to a
source of heat such as a radiator.

Using Multiple Subwoofers: Your 2070Si sub-woofer includes a Line
output connection called “Chain out”. In systems where more than one
sub-woofer is used this allows the signal to be daisy chained to another
one or more sub-woofers. This is just a convenience feature which is an
alternative to using a “Y-Adaptor” at the amplifier output. Please note that
the signal is a straight pass-through and so all sub-woofers must be set­up independently using their controls as normal.

The following section is divided between home cinema installation and
standard stereo installation. Please refer to the relevant section for your
system.

Multi-Channel AV System

Connections

Standard Connection is via the Line level RCA phono Inputs. For a typical
AV system set-up you will need a single RCA phono interconnect. As this
cable is likely to be quite long, make sure you get a good quality fully

sizes and positions for all the other speakers in your system. If you have
the option to set the crossover frequency on the other channels make
sure this is set appropriately to your speakers. Set the distance (or delay)

Multi-Channel AV System

Setting Up
Play some stereo music you are familiar with and experiment with the

Phase invert setting and level control until you hear a seamless blend
between the front speakers and the subwoofer. If you can hear the
subwoofer standing out it's too loud!

Always bear in mind that the human ear's sensitivity to bass varies
enormously with the volume level, hence the need for a wide range of
programme material and sound levels. Once you are happy with the
sound you can then fine tune the performance by using the included CD.

Many Home Theatre amplifiers have distance settings which build in a
time delay depending on the distance of the speaker from the optimum
listening position; the sweet spot. The location of the subwoofer is one of
the most important aspects of any Home Theatre system therefore
getting these settings correct will give a significant improvement to the
system's overall performance. Included with the 2070Si Subwoofer is a
CD designed to assist in the setup of the AV amplifiers distance/time
delay settings.

Set-Up Disc: The disc contains six tracks, each one plays pink noise (20
Hz to 1000Hz) through a combination of one speaker and the subwoofer.

Track one: Subwoofer and Front Left speaker
Track two: Subwoofer and Front Centre speaker
Track three: Subwoofer and Front Right speaker
Track four: Subwoofer and Rear Right speaker
Track Five: Subwoofer and Rear Left speaker
Track six: Subwoofer and all speakers

Choose whichever front speaker is closest to the subwoofer and play the
corresponding track. For instance if it is the front right speaker then play
track three. Adjust the amplifier distance/time delay settings for the
subwoofer by the smallest amount possible. This can be increased or
decreased, it's not important which. For instance if the distance is set to
4m then change it to 4.1m or 3.9m. Listen to see if the pink noise
becomes warmer and fuller or thinner in tone.

If you chose 4.1m and the sound became fuller in tone then change the
setting again to 4.2m and so on until the sound starts to become thinner
again. If however when you changed to 4.1m and the sound became
thinner try reducing the setting to 3.9m. In this way it should be possible
to find the optimum (warmest) setting.

Connect a good quality stereo RCA phono lead to the L and R inputs on
the 2070Si and connect the other end to the PRE OUT sockets on the rear
of the amplifier.

The subwoofer will automatically add the L and R signals together so that
no information is missed. If you wish to use two subwoofers then you can
run a single RCA phono cable to each subwoofer and thus have a stereo
sub-woofer system.

Ensure that the L output on the amplifier goes to the left hand side sub­woofer and R to the right hand side to preserve the stereo image of the
main speakers. The subwoofers will need to be placed close to their
respective main speakers and the set-up will need to be done separately
for each sub-woofer.

Stereo System

Setting Up

Always bear in mind that the human ear's sensitivity to bass varies
enormously with the volume level, hence the need for a wide range of
programme material and sound levels. Once you are happy with the
sound you can then fine tune the performance by using the remaining
controls.

Crossover: The crossover control determines at what frequency your
sub-woofer output begins to rapidly diminish. This should be set so that it
corresponds with the frequency your main speakers begin to produce a
strong output by themselves. The adjustment allows for a smooth
handing over between sub-woofer and main speaker output. If this
setting is too low there will be a 'hole' in the sound where certain
frequencies are weak, conversely if it is too high there will be an
exaggeration of certain frequencies producing an overpowering bass.
You can get an idea of the correct setting from your main speakers
specification sheet, look for the lowest frequency that the speaker
produces (the “-3dB point”) under the “Frequency response” heading.
Room positioning has a dramatic effect on low frequency reproduction
of both the sub-woofer and your main speakers so don't be worried if you
find you require a setting which does not correlate with the specified low
frequency point of your main speakers.

Setting up can take many hours of listening because all of the controls on
your subwoofer will interact; there is no easy route to success. The best
phase invert switch position is strongly affected by the chosen crossover
frequency so as you fine tune the controls you may wish to keep trying
the alternative setting to see which you prefer.

Once you feel you are close with the settings you can now perfect the
integration between sub-woofer and main speakers by adjusting the
phase control. This control is unique in that it uses a pure delay, made
possible by the integrated Digital Signal Processor, and so does not add
sound damaging “group delay” as with most sub-woofers. The DSP
scales the available delay so that this control always provides a 0 – 180°
phase shift at the chosen crossover frequency. This control affects the
level of bass produced at the crossover frequency and also how
smoothly the transition occurs. Again this will interact with the crossover
control so fine adjustments of the crossover frequency may be
necessary to produce the best results. Also you may find you can get to a
better end result by flipping the phase invert switch and trying to optimise
the crossover and phase controls again. Experimentation is the key to
getting perfect integration; once this is achieved you should never be
aware of any sound coming from the direction of the sub-woofer itself.
The end result will be a system with powerful, extended bass response
which appears to be coming from the soundstage between the main
speakers.

6.1 and 7.1 connections are the same as 5.1 connections
with the addition of the extra effects channel/s.

When running loudspeaker cables be especially careful not
to run them across open floor areas where they could be a
source of danger. Run loudspeaker cables around room
boundaries whenever possible.

Line level signal cables should be run away from mains

Placement: The Front and Centre speakers should be in line. If this is not
possible, consult your processor manual for guidance on adjusting
relative centre/front delay times. If you have a 5.1 system, the listening
seat can be closer to the rear wall. As always, be prepared to experiment.

Bass Management: AV processors offer the choice of ‘Large’ or ‘Small’
for the speakers. If you choose ‘Large’ the speaker receives the full
frequency. Choose ‘Small’ and the bass is sent to the Subwoofer. We
recommend you choose ’Small’ for the 2000Ci and the 2010i and 2020i
wherever they are used in the system. The 2050i should be set to ‘Large’.

The subwoofer option should be enabled (set to ‘ON’ or ‘YES’)
Levels: When the basic system parameters have been established, put

your processor into the ‘setup’ routine. Set up each individual speaker so
that the level is the same at the listening position as all the others. If your
processor enables you to adjust the delay times, follow the instructions
closely as this will profoundly affect the final result. When you play a
movie you may think the rear channels are too soft - they aren’t! You may
however have to adjust the subwoofer level both at the processor and at
the subwoofer. Once set, do not re-adjust these levels.

LFE: The LFE channel sends all the bass sound effects to the subwoofer.
If speakers are set to ‘Small’ , system bass from those channels is also
sent to the subwoofer. If you play the system at extreme levels and/or
have the subwoofer level set too high you may overdrive the subwoofer
with unpleasant sonic results. If this occurs, reduce the level
immediately.

Phase: If your speakers are incorrectly wired the bass will be blurred and
thin. In this case, check the wiring carefully. If your speaker wire has a
tracer along one core, consistently use the striped core to connect all the
positive (RED) terminals. In this way the system will always be in phase.

Always follow the instructions in your AV processor manual!

Série Q Acoustics 2000i

Introduction

La gamme d’enceintes de série Q Acoustics 2000i est conçue pour répondre
aux besoins des cinéphiles et des amateurs de musique. Notre gamme
comprend :

2010i : Une enceinte d’étagère compacte avec un caisson de basses de
100mm.

2020i : Une enceinte d’étagère avec un caisson de basses de 125 mm.
2050i : Une enceinte colonne avec deux caissons de basses de 165 mm
2000Ci : Une enceinte centrale avec deux caissons de basses de 100 mm,

pouvant être fixée au mur, si nécessaire.
2070Si : Un subwoofer actif de 140 Watt avec un haut-parleur de 2 X170 mm

et un détecteur de signal pour allumage/arrêt automatique.
Vous pouvez effectuer un bi-câblage sur toutes les enceintes passives sauf la

2010i et la 2000Ci.
Toutes les enceintes fonctionnent à proximité des écrans de télévision sans

aucun problème à l’exception des enceintes de la gamme 2000Si, qui ne
doivent pas être placées à moins de 500 mm d’écrans de télévision ou de tout
autre matériel pouvant être perturbé par un champ magnétique. Cela
n’affecte pas les écrans à plasma ni les écrans à affichage à cristaux liquides.

Avant de brancher vos enceintes, assurez-vous que toutes les parties actives
de votre système audio sont éteintes ou hors tension.

Lorsque vous allumez votre système audio ou lorsque vous changez les
sources d’entrée, baissez le volume jusqu’à un bas niveau. Montez
graduellement le son.

Ne montez JAMAIS le son au maximum. Le bouton de contrôle du volume est
trompeur et n’indique pas la puissance du système audio. L’utilisation du
volume au maximum peut endommager votre capacité auditive.

Ne raccordez PAS les bornes de votre enceinte au secteur.

Ne laissez PAS vos enceintes dans des endroits trop froids, trop chauds, trop
humides ou au soleil.

Si vous utilisez vos enceintes sans les grilles de protection, faites bien
attention à ne pas endommager les haut-parleurs.

N’utilisez PAS des pieds de fortune. Installez vos enceintes sur des pieds
recommandés par Q-Acoustics selon les instructions, en utilisant les pointes
de fixation fournies. Votre revendeur pourra vous conseiller.

NE démontez PAS vos enceintes car vous annuleriez la garantie.

Déballer vos enceintes

Déballez complètement vos enceintes. Sortez les enceintes du carton en
soulevant les enceintes elles-mêmes. Ne vous servez pas de sacs en pour les
soulever. Les enceintes 2050i et 2070Si sont assez lourdes; demandez de
l’aide pour les soulever, si nécessaire.

Lorsque vous déplacez les enceintes, ne les traînez pas par terre car vous
risquez de les endommager. Soulevez-les avant de les déplacer.

Vous trouverez dans le carton : Le(s) enceinte(s) et ce mode d’emploi.

Pour les modèles suivants, le carton d’emballage contient également :

2050i : Un jeu de clous de plancher et de capuchons de clou pour chaque
haut-parleur. Une clé Allen pour régler les clous une fois installés.

2070Si : Un cordon d'alimentation adapté à l'alimentation secteur dans votre
région, 2 câbles RCA/Phono à angle droit, Un disque CD d'installation AV.

Vérifiez bien le produit. Si l’un des articles est manquant ou endommagé,
contactez votre revendeur dès que possible.

Conservez l’emballage pour transporter le matériel ultérieurement. Si vous
décidez de jeter l’emballage, respectez la réglementation de votre pays en
matière de recyclage.

Une fois l’enceinte à l’endroit,
resserrez chaque fixation avec la clef
hexagonale en partant du haut et
ajustez plus ou moins les fixations
jusqu’à ce que l’enceinte soit à
niveau et parfaitement stable.

Fixations au sol très pointues. Faites très attention !
Ne placez jamais une enceinte avec des pointes de fixation dans des endroits
pouvant être endommagés !
Soulevez toujours vos enceintes pour les déplacer; ne les tirez jamais !

Vérifiez que les bondes sont bien enfoncées dans l'orifice sans aller trop loin.
Vous constaterez que le niveau des graves diminue, mais que la définition et
l'extension des graves augmentent. Testez pour voir la solution que vous
préférez et changez la position du haut-parleur, par petits intervalles, de
manière à optimiser le résultat final.

Laboratories.

2050i

Les enceintes 2050i doivent être positionnées à 200 mm minimum du mur
arrière et à 500 mm des murs latéraux. En plaçant vos enceintes plus près du
mur, vous augmenterez les graves, mais cela peut résonner et manquer de
précision et de qualité. Les enceintes doivent être bien placées, tournées vers
l’auditeur et situées de 2 m à 4 m de distance les unes des autres. Tourner
légèrement les enceintes vers l’intérieur améliore la qualité stéréo mais réduit
la source sonore.

2010i et 2020i

Les enceintes 2010i et 2020i doivent si possible être montées sur des pieds
Q-Acoustics ou fixées au mur. Si vous choisissez de les mettre sur des pieds,
l’unité des aigus doit être à la hauteur des oreilles de l’auditeur. Les enceintes
montées au mur peuvent être placées être un peu plus haut et inclinées vers
le bas. Les enceintes sur pieds doivent être traitées comme des enceintes
colonnes mais peuvent être placées un peu plus près du mur arrière. Ces
enceintes peuvent également être placées sur des étagères.

Un support conçu spécialement pour fixer les enceintes Q Acoustics 2010i,
2020i et 2000Ci au mur, est en vente chez votre revendeur. Des pieds pour les
enceintes 2010i et 2020i sont également disponibles.

Soyez prêt à expérimenter afin de trouver le meilleur agencement possible,
adapté à votre goût, dans la pièce que vous avez choisie.

Enceintes à effets
2000Ci

Le modèle 2000Ci a été conçu pour être utilisé à proximité d’un écran de
télévision. Il doit être placé directement au-dessus ou au-dessous de l’écran.
Si vous possédez un téléviseur traditionnel, assurez-vous qu’il puisse
soutenir les enceintes et qu’il offre une surface égale. Dans le cas contraire,
placez le téléviseur dans un meuble télé et l’enceinte 2000Ci sur une étagère
solide directement en-dessous du téléviseur.

Si vous possédez un écran à plasma ou à affichage à cristaux liquide, fixez
l’enceinte 2000Ci au mur ou sur toute autre surface adéquate directement au­dessus ou au-dessous

de l’écran.

Enceintes Surround

Il y a des recommandations de Dolby labs pour les
enceintes à effets 5.1.

Montez les enceintes surround de chaque côté de
l’auditeur, légèrement en retrait par rapport à la
position d’écoute. Les enceintes doivent être
tournées vers l’intérieur et montées sur les murs
latéraux ou bien, si la pièce est large, montées sur des
pieds hauts, le centre des enceintes se trouvant au­dessus du niveau de l’oreille de l’auditeur.

Brancher les enceintes passives

Borniers et Connecteurs

Les enceintes 2020i et 2050i peuvent être installées avec un bi-câblage. Le
principe du bi-câblage requiert quatre bornes. Les deux bornes supérieures
sont reliées à l’enceinte des aigus (HF) et les deux bornes inférieures sont
reliées à/aux enceinte(s) des graves (LF). Ces bornes sont livrées avec des
liaisons amovibles servant à relier les bornes entre elles. Cela vous permet de
brancher les enceintes de manière traditionnelle avec une paire de câbles ou
en « bi-câblage » avec les double-borniers.

Les enceintes 2010i et 2000Ci ont des bornes standard.

Câble des enceintes

Des câbles d’enceintes spécialisés vous permettront d’atteindre une
meilleure qualité de reproduction des sons que les câbles multi-usages
traditionnels, comme les fils de sonnerie. Utilisez des câbles avec une
quantité assez importante de cuivre pour les enceintes centrales et avant.
Les câbles fins diminuent les graves et limitent la gamme dynamique. Les
enceintes surround (arrières) sont moins importantes.

Les câbles d’enceinte possèdent une rayure ou un tracé en leur centre. Ils
sont traditionnellement reliés aux bornes
positives. Les câbles reliant l’amplificateur
aux enceintes avant doivent être de la même
longueur. Ne raccordez jamais deux câbles –
utilisez la longueur entière.

Préparer les câbles

Dédoublez les câbles sur 40 mm. Dénudez
les fils de 10 mm et tournez les fils pour tous
les rassembler. Sectionnez le câble en en
laissant 7 mm à nu.

Branchement

Dévissez la borne dans le sens contraire des
aiguilles d’une montre pour faire apparaître le
trou de montage prévu à la base de la borne.

Insérez la partie dénudée du câble dans le
trou. Resserrez complètement la borne à

la main. Assurez-vous qu'aucun fil ne
dépasse qui pourrait entrer en contact avec
les bornes adjacentes.

Les règles européennes de sécurité
interdisent l’utilisation de fiches de 4 mm.
