First of all, congratulations on your purchase of an active subwoofer from
quadral. It is with discerning music lovers and connoisseurs like yourself in
mind that we build hi-fi and surround speakers to standards way beyond
the norm. On the following pages we would like to give you some useful tips
on setting up, connecting up and operating your quadral active subwoofer to
ensure many hours of pure listening pleasure.
Safety notes on active loudspeakers
Please read these user instructions carefully and follow all recommended steps towards putting
your system into operation. You should at all times be aware of and take note of the warnings
and safety instructions on the device and in these user instructions. Keep these user instructions in a safe place so you can find them straight away if you should have any queries or
problems at a later date.
• Your set has been drafted for the usage at 115 V~ 60 Hz or 230 V~ 50 Hz mains supply. Please
make sure before using the system, that the corresponding working voltage for your country has been
adjusted on the back of the set (by delivery it is 230 V~ 50 Hz).
• Lay the mains cable and other cables in such a way that they cannot be stepped upon, or crushed
or damaged by spikes or furniture, or cause anyone to trip over them. The mains plug shall remain
readily operable.
• When removing the mains cable from the wall socket, do so by pulling the plug out and not by tugging the cable itself.
• Unplug the mains cable in the event of storms or if you are not going to be using the system for a
longer period of time.
• The loudspeaker connection terminals (High Level Input and Output) may only be used in conjunction
with the corresponding amplifier outputs or satellite speakers. Connection of any kind between these
terminals and the mains supply (230V/115V) is prohibited and will lead directly to the immediate
destruction of the loudspeaker and all connected products. For this reason it is essential to avoid fitting these cable connections with plugs which could in any way whatsoever be confused with mains
plugs.
• At high volumes and depending on the connected power amplifier, voltages of over 30V can be
present at the loudspeaker connection terminals marked High Level Input and Output. These terminals
should therefore on no account be touched while the system is active.
• Our subwoofers are desigend for use in normal living roomes and moderate climates only and should
never be set up and operated in damp rooms or tropical climates. They never get in touch with dripping or splashing water. Furtheron no objects filled with liquids, such as vases, should be placed on
the sets.
• Massive overloading of loudspeakers due to excessively high volume levels can, under certain
circumstances, lead to the fusing of individual elements or speakers in spite of safeguards. Theoretically, overloading to this extent can even cause fire inside a loudspeaker, so it is advisable to keep
loudspeakers under surveillance when being operated at such outer technical limits.
• Faulty safeguarding, if accessible from outside, has to be replaced only by equal types.
• The temperature of the rear heat sink can rise to over 60°C when the unit is used over a longer period
of time at high volumes, so please at all times avoid touching it when it is active.

• When operating your subwoofer, on no account ever lay it with the panel containing the switches,
controls and input/output sockets facing down as this could cause the unit to overheat; please ensure
a minimum distance of 5cm around the apparatus for sufficent ventilation. The woofer, the bass
reflex opening and possible existing ventilation openings should never be covered with items such as
newspapers, table-cloths, curtains, etc.
• On no account ever insert a hand, arm or any object into a loudspeaker’s sound outlets (e.g. bass
reflex pipe) as this could cause injury or material damage. At particular risk in this respect
are children and pets.
• Allow no-one but appropriately qualified service engineers to carry out technical maintenance and
repair work on your active loudspeaker. This will be necessary in the event of any form of damage,
i.e. damaged mains cables and plugs, or when some object has fallen onto the speaker cabinet or
if the unit itself has fallen over or been dropped, or if it has been penetrated by any type of liquid.
Never open up the device yourself since any physical contact whatsoever with the mains voltage
(230V/115V) can have fatal consequences.
• Never use active loudspeakers as seating or climb up on them (instead of using a ladder)!
• Your loudspeaker units have been designed for long years of home use and should not therefore be
used for professional purposes.
• For the purposes of mounting and placement of these products, please only use furniture and other
devices that are obtainable from the manufacturer and marketed for or together with the product in
question. Take extreme care when moving any table devices or shelves upon which the products are
placed as the units could otherwise tip or fall over and cause damage or injury.
• Avoid placing your loudspeakers anywhere with high levels of humidity or dampness. Permanent
relative humidity or exposure to direct sunlight (UV radiation) can cause warping of wooden speaker
cabinets or lead to their premature aging and thus affect the unit's performance. Besides, do not
position the subwoofer directly adjacent to sources of heat, e.g. radiators. Moreover, do not place
naked flame sources, such as lighted candles on the speaker cabinet.
• Our fitting accessories should only be used to install products that we have specifically designed for
wall mounting. Take special care to ensure that all components are securely screwed into place! We
also recommend using additional safeguards, for example chains, etc. to ensure secure and safe
mounting.
• Loudspeakers in operation for long periods at excessively high volume levels are not only a source
of disturbance for neighbours but can also have serious health-related consequences for the user as
well!
• Loudspeakers without magnetic shielding can cause discoloration or distortion of the TV picture. To
avoid this, place non-shielded loudspeakers at least 50 cm clear of the TV set. Please avoid depositing, for example, credit cards, diskettes, audio or video cassettes or any other form of magnetic data
carriers on the speaker cabinet as this could otherwise lead to loss of data stored on such objects.
Likewise, do not place and operate magnetic tape devices in the direct vicinity of such loudspeakers.
• Please do not throw the packaging away as you might possibly need it for transportation of the loudspeaker system at a later date. Keep the polythene bags out of the reach of children since
they can cause asphyxiation if used for any other than their intended purpose.
Setting up
Besides the unit’s actual settings, a subwoofer’s bass reproduction essentially depends on
where the unit is positioned in the listening room. Proximity to walls or even placement in
a corner makes the bass sound come over louder – but also less well defined and accurate
– than if in a more free-standing position. Since the acoustic characteristics differ from room
to room, we recommend finding the optimum compromise between bass volume and precision by simple trial and error. It won’t matter if you set up the subwoofer nearer to the left
hand satellite than the right hand one – or vice versa – since the low bass sounds are not
localizable.
If your subwoofer directs its sound downwards, you must fit the supplied loudspeaker foot,
which can be designed as „spikes“ as well (depending on the model), before you start to use
the system.
Operating modes
Units with a POWER switch for mains and a POWER switch for stand-by:
If the mains POWER switch is in OFF position, the unit is turned off completely. If the mains
POWER switch is in ON position, the switch for stand-by operates as follows:
ON: The unit is permanently on.
STAND BY: The unit switches on automatically, if a music signal is received and auto-
matically switches to stand-by mode after approximately 15 minutes, if no
music signal is received.
OFF: The functions are switched off. The amplifier will be kept at temperature to
continue operation soon.
Units with POWER switch for mains and AUTO switch for stand-by:
If the mains POWER switch is in OFF position, the unit is turned off completely. If the mains
POWER switch is in ON position, the switch for stand-by operates as follows:

OFF: The unit is permanently switched on.
ON: The unit switches on automatically, if a music signal is received and auto matically switches to stand-by mode after approximately 15 minutes, if no
music signal is received.
Units with POWER switch for stand-by only:
The switch operates as follows:
ON: The unit is permanently switched on.
AUTO: The unit switches on automatically, if a music signal is received and auto matically switches to stand-by mode after approximately 15 minutes, if no
music signal is received.
OFF: The functions are switched off.
Units with POWER switch for mains only:
If the mains POWER switch is in OFF position, the unit is turned off completely.
If the mains POWER switch is in ON position, the unit is in automatic mode. I.e. if a music
signal is received, the unit switches from stand-by mode to operation mode (ON) and switches
back to stand-by mode, if no music signal is received for approximately 20 minutes.
Connecting up
Before connecting up the subwoofer to your hi-fi or surround system, make sure that the unit
and all system components are switched off, i.e. the pilot lights should all be off.
Connection variant no. 1
(Subwoofer/satellite system for hi-fi and surround)
First take one of the 3m loudspeaker cables supplied with your subwoofer and connect it
to the left-hand speaker output of the amplifier and the left-hand input (HIGH LEVEL) of the
subwoofer. The red „+“ terminal of the amplifier must be wired to the red „+“ terminal of the
subwoofer; the amplifier’s black „-“ terminal must be wired to the black „-“ terminal of the sub
woofer. The „+“ line is always coloured red or marked accordingly on speaker cables. Now
repeat the procedure with the second loudspeaker cable to connect the amplifier’s right-hand
speaker output with the subwoofer’s right-hand input. Here too, please take particular care
to ensure that the cables are connected up with the correct polarity, i.e. the red „+“ terminal
of the subwoofer connected to the red „+“ terminal of the amplifier, the black „-“ terminals
connected to each other likewise. By doing so, you will avoid considerable impairment of the
sound as a result of incorrect polarity.
Having connected up your subwoofer at the front-speaker outputs of the digital surround
sound amplifier as shown above, you must now configure the amplifier's bass management
as follows:
Front: large
Subwoofer: no
Centre, rear: large /small (depending on size)

Connection variant no. 2
(Additional woofer for an existing hi-fi system)
Connect the subwoofer to your amplifier at the „B“ loudspeaker outputs. The connections of
the existing speakers remain unchanged. Having connected the subwoofer, you must then
activate the „B“ loudspeaker outputs; your amplifier’s operating manual will tell you how to
do this. Put your subwoofer into operation as described under „Starting up“.
This operating mode can only be used if you can activate the speaker outputs A & B on your
amplifier simultaneously. Please consult your amplifier's operating manual accordingly.
For operation with a surround sound amplifier, please follow the instructions given in "Con
-
nection variant no.1".
Connection variant no. 2
(Differences of models cause a different position of the operating elements.)
Connection variant no. 3
(Subwoofer in a preamp/output amp combination: not possible on all subwoofers)
If your system consists of a preamp/power amp combination you can, connect the subwoofer
to the preamp’s output by means of a cinch cable. To do this, use the cinch sockets marked
„LOW LEVEL IN“. Also using a cinch cable, connect up your output amp to the subwoofer at
the cinch socket „LOW LEVEL OUT“. If your preamp has 2 pairs of output sockets you can
leave the direct connection between preamp and output amp as it is and simply connect the
subwoofer to the preamp’s second cinch output; there is then no need for the subwoofer to be
connected to the power amp. In both these cases there is no need to use loudspeaker cables
for the connections. Put your subwoofer into operation as described under „Starting up“.
Connection variant no. 3
(Differences of models cause a different position of the operating elements.)
Connection variant no. 4
(Subwoofer in a surround system)
If your surround amp or receiver has a subwoofer line output (Sub Pre-Out), you can use this
by connecting the subwoofer to this socket by means of cinch cable (Connection variant no.
4a or 4b). If your surround amp does not have an output of this type you will have to connect
up the subwoofer as described under „Connection variant no. 1“.
Having connected up your subwoofer at the subwoofer line output of your digital surround
sound amplifier, you must now configure the amplifier's bass management as follows:
Subwoofer: yes
Front, center, rear: large /small (depending on size)
Connection variant no. 4a
(Differences of models cause a different position of the operating elements.)

Starting up
Having correctly connected up your subwoofer as described in the above, first switch on your
amplifier. Now switch on your subwoofer by means of the mains switch on the rear panel.
The indicator must then light up. When it does so, this means that your subwoofer is now
ready for operation.
When the unit has been switched on you can now adjust the subwoofer to achieve the ideal
balance. This will only be necessary once unless you purchase new speakers. In this case you
will have to balance the subwoofer again with the new speakers.
Now put your system into operation with a music signal. First set the Frequency control to
centre (neutral) position. Now slowly turn the Volume control clockwise until a tonal balance
is established in the bass range between the subwoofer and your satellites. You can use the
Frequency control to adjust the crossover range.
The general rules here are:
large satellites (boxes), turn the control further anticlockwise
and
small satellites (boxes), turn the control further clockwise.
Having adjusted the Frequency control it might be necessary to readjust the Volume control
to achieve an ideal tonal balance again. The superimposition of your satellites’ sound waves
and those of the subwoofer can lead to interference at your listening position. At worst, this
means that the bass sound you hear there will be no more than “subdued“ despite correct
setting of Frequency and Volume controls. If this is the case, please turn the Phase control on
the rear panel to the 0° or 180° position (not possible with the SUB 45).
At a point of the Phase control you will notice the bass sound becoming more powerful
and punchy. By experimenting and listening you will thus find the ideal setting to suit your
requirements.
Please note: Always bear in mind that the setting of the subwoofer should be carried out to
suit your listening position. That means that when adjusting a control you should always return
to your listening position to hear whether your adjustment has a positive effect there.
5. Subwoofer electronic
(Differences of models cause a different position of the operating elements.)
Switch for upper transition frequency:
When the selector switch is set at VAR, the FREQUENCY con
troller regulates the upper crossover frequency.
When the selector is set at FLAT, the subwoofer will operate up
into the lower midranges and requires the active filtering of an
AV receiver or AV amplifier.
Operating the subwoofer using the Sub Out
terminal of a surround amplifier
If your surround amplifier offers you the option of adjusting the volume of the subwoofer via
the bass management facility we recommend that you proceed as follows:
Adjust the subwoofer's volume control switch to the "neutral" position, and the Frequency con
-
trol switch to the "maximum" position. Now carry out a volume test on the surround amplifier,
setting the satellites and the subwoofer to identical volume levels.
Please refer to the operating instructions supplied with your surround amplifier for details on
volume adjustment.

As far as possible, leave the bass control of the amplifier's tone control facility set in the
"neutral" position, otherwise unnecessarily strong bass signals will be delivered to the satellite
speakers; whilst the satellites would then be subject to a heavy load from such bass signals,
they are not be able to reproduce them in the form of low-frequency sound. As described in
the above, set the bass volume to the level you require by adjusting the subwoofer's volume
via the amplifier's bass management facility.
Maintenance of loudspeakers
The best way to clean your quadral loudspeakers is with a dry and soft duster. Please mop
the aluminium cabinets in longitudinal direction with a moist duster. Never use solvents!
You should clean the loudspeaker systems (bass, midranges, etc.) only by an intense soiling
(slight quantity of dust is acoustically insignificant) exclusively with a dry, soft duster and just
with a little pressure because you can damage them (to dent the membranes).
If the silver front frames are soiled please use a dry cleaning foam ( i. e. Centralin – Spray),
spray the soiled spot, allow it to react and vacuum it with a Hoover.
Don´t brush off the black front frames, just dust off them or draw the dirt carefully off with a
wide adhesive tape. Never clean them moist!

Wir danken Ihnen für die Entscheidung zum Kauf eines aktiven Subwoofers
von quadral. Es sind Musikliebhaber und Kenner wie Sie, für deren gehobene
Ansprüche wir HiFi- und Surround-Lautsprecher einer Güteklasse bauen, die
weit über dem Durchschnitt liegen. Im folgenden möchten wir Ihnen noch ein
paar nützliche Hinweise zum Anschluss, zur optimalen Aufstellung und zum
Betrieb unserer aktiven Subwoofer geben, damit Sie lange Zeit ungetrübt
Ihre Musik geniessen können.
Sicherheitshinweise für aktive Lautsprecher
Lesen Sie die vorliegende Bedienungsanleitung bitte sorgfältig und befolgen Sie alle Schritte
die für die Inbetriebnahme angegeben sind. Beachten und befolgen Sie weiterhin alle Warnungen und Sicherheitshinweise die auf dem Gerät und in der Bedienungsanleitung angegeben sind. Verwahren Sie diese Anleitung so, dass Sie bei späteren Fragen schnell zur Hand
ist.
• Ihr Gerät ist für den Betrieb an 115 V~ 60 Hz oder 230 V~ 50 Hz Wechselstromnetzen konzipiert.
Bitte vergewissern Sie sich vor Inbetriebnahme, dass die für Ihr Heimatland entsprechende Betriebsspannung auf der Geräterückseite eingestellt ist! (Im Auslieferzustand ist dies 230 V~ 50 Hz).
• Das Netzkabel und andere Anschlusskabel müssen so verlegt werden, dass keine Quteschung oder
Beschädigung durch "Spikes", Möbel und durch Trittbelastung auftreten kann und Stolperfallen vermieden werden. Der Netzstecker sollte leicht zugänglich bleiben.
• Das Netzkabel darf aus der Steckdose nur durch ziehen des Netzsteckers, nicht aber an dem Kabel
selbst erfolgen.
• Entfernen Sie den Netzstecker bei Gewitter oder bei längerer Nichtverwendung aus der Steckdose.
• Die Lautsprecheranschlussklemmen (High Level Input und Output) dürfen nur mit den betreffenden
Verstärkerausgängen oder Satellitenlautsprechern verbunden werden. Eine irgendwie geartete
Verbindung dieser Klemmen mit dem elektrischen Netz (230 V/115 V) ist nicht erlaubt und führt
zur sofortigen Zerstörung des Lautsprechers und aller angeschlossenen Produkte. Daher sollte es
vermieden werden, diese Kabelanschlüsse mit Steckern zu versehen die auch nur entfernt zu einer
Verwechselung mit Netzsteckern führen könnte.
• An den mit High Level Input und Output gekennzeichneten Lautsprecheranschlussklemmen kann je
nach angeschlossenem Leistungsverstärker und bei hohen Lautstärken, Spannungen von über 30 V
anliegen. Daher sollten diese nicht während des Betriebes berührt werden.
• Unsere Subwoofer sind nur für den Einsatz in normalen Wohnräumen und für moderates Klima konzipiert und dürfen nicht in Feuchträumen oder tropischem Klima betrieben werden. Ausserdem dürfen
sie nicht Tropf- oder Spritzwasser ausgesetzt werden. Weiterhin dürfen auf den Geräten keine mit
Flüssigkeiten gefüllte Objekte, wie z.B. Vasen, platziert werden.
• Bei einer massiven Überlastung der Lautsprecher durch sehr große Lautstärken ist das Durchbrennen
einzelner Bauelemente oder einzelner Lautsprecher trotz Sicherungseinrichtungen nicht vollständig
auszuschließen. In der Theorie könnte sogar ein Brand innerhalb eines Lautsprechers in einem derartigen Überlastungsfall entstehen. Daher sollten Lautsprecher, die in diesem Grenzbereich betrieben
werden, nicht unbeaufsichtigt bleiben.
• Defekte Sicherungen, soweit von außen überhaupt zugänglich, sind nur durch gleichwertige Typen
zu ersetzen. In diesem Fall ist das Gerät zuvor vom Stromnetz zu trennen.
• Die Temperatur der rückseitigen Kühlfläche/-körper kann bei längerem Hochpegelbetrieb auf über
60°C ansteigen. Daher sollte das Berühren in diesem Betrieb unterbleiben.
• Aktive Subwoofer dürfen während des Betriebs niemals auf die Elektronikseite mit Schaltern, Reglern
und Ein-/Ausgangsbuchsen gelegt werden, sonst können sie überhitzen. Stellen Sie sicher, dass
ein Abstand von 5cm für ausreichende Belüftung rund um das Gehäuse freibleibt. Der Tieftöner,
die Bassreflexöffnung und eventuell vorhandene Belüftungsöffnungen dürfen nicht durch Zeitungen,
Tischdecken, Vorhänge oder ähnliches verdeckt werden.
• Weiterhin sollten keinesfalls Hände, Arme oder sonstige Fremdkörper in die Schallaustrittsöffnungen
(Bassreflexrohre) gesteckt werden, um Verletzungen oder Schäden zu vermeiden. Kinder und
Haustiere sind hier im besonderen gefährdet.
• Die Wartung und Reparatur Ihres Aktiv-Gerätes überlassen Sie bitte ausschließlich dem technischen
Service von quadral. Wartung wird notwendig, bei jeglicher Art von Schäden, d.h. bei beschädigten
Netzkabeln und Steckern, oder nach dem Herabfallen von Gegenständen auf das Gerät, sowie dem
Sturz des Gerätes selbst oder nach dem eindringen von Flüssigkeiten. Öffnen Sie das Gerät nie
selbst, da jeder Umgang mit der Netzspannung (230 V/115 V) lebensgefährlich ist.
• Lautsprecher dürfen keinesfalls als Sitzmöbel oder Kletterhilfen (Leiterersatz) benutzt werden!
• Ihre Lautsprecher wurden für einen langjährigen Heimgebrauch konzipiert, und dürfen daher nicht
im professionellen Einsatz betrieben werden.
• Verwenden Sie bitte ausschließlich Möbel und andere Geräte zum Anbringen und Draufstellen der
Produkte, die beim Hersteller erhältlich sind und für oder mit dem Produkt vertrieben werden. Beachten Sie bitte, dass Tischgeräte oder Regale, auf denen die Produkte platziert werden, sehr vorsichtig
zu bewegen sind, um Schäden oder Verletzungen durch ein umkippen zu vermeiden.
• Schützen Sie ihre Lautsprecher gegen Luftfeuchtigkeit und Nässe. Eine dauerhaft hohe Luftfeuchtigkeit
oder Sonneneinwirkung (UV-Strahlung) kann Ihre, aus Holz gefertigten Gehäuse aufquellen oder
vorzeitig altern lassen und somit die Funktionsfähigkeit beeinflussen. Auch sollten sie nicht in unmittelbarer Nähe von Wärmequellen, wie z.B. Heizkörpern aufgestellt werden. Weiterhin dürfen keine
offenen Flammen wie z.B. Kerzen auf dem Gehäuse abgestellt werden.
• Nur Produkte die von uns für eine Wandmontage vorgesehen sind, dürfen mit unserem Zubehörmaterial befestigt werden. Besondere Sorgfalt ist auf eine ausreichend sichere Verschraubung aller
Komponenten zu legen! Zusätzliche Sicherungseinrichtungen (Ketten, etc.) sollten montiert werden.
• Sehr große Lautstärken im Dauerbetrieb werden nicht nur von Ihren Nachbarn als störend empfunden, sondern können auch für den Anwender zu Gesundheitsschäden führen!
• Magnetisch nicht abgeschirmte Lautsprecher können das Fernsehbild verfärben oder verzerren. Ein
Abstand von 50 cm ist im allgemeinen ausreichend, um derartige Störungen zu vermeiden. Vermeiden Sie bitte die Ablage von z.B. Kreditkarten, Disketten, Audio oder Videokassetten oder anderen
Magnetträgern auf dem Lautsprecher. Die dort gespeicherten Informationen könnten zerstört werden.
Ebenso sollten Magnetbandgeräte nicht in unmittelbarer Nähe betrieben werden.
• Bitte heben Sie die Verpackung für einen eventuell späteren Transport auf. Halten Sie die Poly-
beutel von Kindern fern, da hier bei unsachgemäßem Umgang ein Erstickungsrisiko
