Warranty terms

12 year warranty for speakers and 2 year war­ranty for power amplifiers and electronics (from
purchase date) on materials and work time, with
the exception of damage caused by incorrect use
or electrical or mechanical overload. An original
copy of our invoice is required as the warranty
document. This warranty is exclusively valid for
speakers, power amplifiers and electronics that
have been purchased from Teufel for private use
by end customers. The warranty is not valid for
speakers, power amplifiers and electronics that
the end user has purchased from a different dis­tributor. If the Teufel product is sold on privately,
the warranty may be transferred to the purchaser,
providing that the original proof of purchase is
also transferred.

Returns

Teufel guarantees an eight-week right of ex­change or return with rebate of the purchase
price paid.
The return of individual components of a kit is
only permitted if these components can also be
purchased individually from Lautsprecher Teufel.
When one or individual components are retur­ned, the price discount that Lautsprecher Teufel
guarantees for all components of a kit as part
of the set price shall no longer be valid. For the
components returned, customers shall therefo­re be refunded only the difference between the
set price and the purchase price of the individual
components that they are keeping. The economic
outcome for customers is as if they had bought
the remaining components at the individual price
from the outset.

You can find more information about returns on

Safety information

Important: Please read through these operating instructions

very carefully. It is essential that you take note of all of the sa­fety information and operating instructions before switching on
the appliance. Please keep these operating instructions in a safe
place for future reference.

Important: Please read the operating instructions. You should
also follow all instructions for start-up and ongoing use.

Information on cleaning: Please do not attempt to clean the
appliance using household chemicals because they could damage
its surface. Simply use a dry cloth. Disconnect the appliance from
the mains before cleaning.

Caution – moisture and sunlight: Never operate the appliance
in damp rooms, i.e. close to baths, showers, wash basins, drains,
damp cel lars or swimming pools; never us e it where there
is moisture. Never expose the speakers to high air humidity
and avoid direct sunlight. Do not expose device to dr ipping or
splashing water. Do not place objects filled with liquids, such as
vases on the device.

Information on location: Do not use the appliance unsecured
in vehicles, in unstable places, on wobbly tripods or furniture or
supports that are too small. The speakers could fall and cause da­mage to people, including yourself. Speakers, particularly if posi­tioned on stands or on the TV/monitor, may fall and cause damage
due to their weight, even if they have been positioned securely
and stably, as a result of external influences (pulling on the cable,
tripping over the cable, unintentional physical contact). This also
applies to wall suppor ts that have been attached inappropriate­ly or incorrectly to walls that may not be capable of suppor ting
their weight. Only use suitable wall brackets for mounting. Make
sure that you know how much weight the walls can bear. The ap­pliance must not be placed near sources of heat. This includes
radiators and heaters, ovens and other appliances that emit heat
(e.g. amplifiers). Sources of heat , such as fan heaters or candles,
should not be placed on the speakers.

For ventilation: Any slits and openings in the casing have been
provided for ventilation. Their purpose is to guarantee reliable
operation and to prevent the appliance from overheating. These
openings must not be blocked or covered, including by placing
the appliance on a bed, sofa, carpet or other soft surface. Do not
place any newsp apers or table cloths, etc. on the appliance. The
cooling plate of the amplifier electronics must not be covered or
exposed to direct sunlight. Additional active cooling of the appli­ance is generally not permitted.

Electrical supply: The subwoofer must only be supplied from a
power source with the correct voltage as specified on the iden­tification label. If you are unsure about the electricity supply
in your home, please contact us or your electricity supplier for
more information. The device must be grounded. Please only use
the appropriate power cable for connecting to the power socket.
Do not modify the power cable under any circumstances! You
must comply with regulations regarding polarity and grounding.
The power socket of the device will only accept a 3-pin power
plug. Make sure the power switch is in the “off” position before
connecting or disconnecting the device.

Information on wiring: Please place the supply cable flat and
flush to the wall and floor. Cables that are laid loosely represent a
risk of tripping. This could also result in interference and cause
the sound to be disrupted. The electricity supply cable should
be laid so that it is not likely to be stepped on or squashed from
the sides or above by heavy objects. Damaged cables must be
replaced. Pay particular attention to the cable/plug connection,
the mains socket and the cable output from the subwoofer. The
power supply cable and the cables that connect the speakers

should be checked regularly for insulation faults or breaks. If a
fault is discovered, the appliance and the cabling must be dis­connected from the mains immediately and the defective cable
must be replaced.

During periods without use: Remove the subwoofer ’s power
supply cable from the socket for longer periods of absence or
non-use.

During thunderstorms: In order to avoid damage caused by
lightning str ikes, the appliance should be switched off and also
detached from the mains socket as soon as a thunderstorm is
expected.

Risk of overload: You should not overload wall sockets, exten­sion cables or integrated appliance sockets, because this could
potentially lead to short circuits and even fires. You should also
avoid turning up the volume very high on the relevant amplifier,
especially if you have increased the bass using the bass control,
the loudness button or one of the deep bass boost switches.

Foreign bodies and liquids: Foreign bodies and liquids must not
get into the appliance via its openings under any circumstances,
as they could come into contact with par ts carr ying high vol­tages, which could then cause shor t circuits and fires. Therefore
do not spill any liquids of any kind on the appliance. Troubleshoo­ting: Do not attempt to repair the appliance yourself. Contact our
service depar tment first for authorisation if you think that you
can repair the fault yourself. Otherwise the appliance must be
sent to our service depar tment.

Transport: The appliance should be transported using a hand
truck. Great care must be taken during transport . Please note
that uneven surfaces, sudden stopping or inappropriate exertion
of force may cause the hand truck and the load to fall over.

Information on spare parts: Lautsprecher Teufel will provide
you with spare parts during the warranty per iod. Your warranty
will not be invalidated if you replace the parts yourself on-site
using Lautsprecher Teufel spare parts.

Unusual sounds: If any unusual sounds occur during use or the
sound becomes distorted, the speaker output must be reduced
immediately so that the system plays an undistorted sound.

Connecting and changing the fuse:

Disconnect the mains plug. A faulty fuse may only be exchanged
for one of the same type.

Information on volume: Loud noises can damage hearing. Sud­den high pressure may be created, par ticularly if a “subwoofer”
in “Standby/Auto On” mode is switched on by a bass impulse at
full volume. In addition to physical damage, please be aware of
possible psychological consequences. Children and pets require
particular care. If necessary, set the volume control of your si­gnal source appliance to the lowest level. At high volumes, always
keep a cert ain distance from the appliance and never have your
ears right next to the speaker.

Please read the following

safety information carefully.

Risk of suffocation – keep

packaging materials (e.g. the

plastic lm) out of the reach and

sight of children.

Risk of electrocution – do not

leave children unsupervised with

electrical appliances!

In case of emergency

If any of the following occur
disconnect the appliance from
the mains and consult our tech­nicians:

4 If the plug or cable are

damaged

4 If foreign bodies or liquid

have entered the appliance

4 If the appliance has been in

direct contact with rain or
other water

4 If the appliance does not

play, even though you have
followed the operating
instructions

4

If the appliance has been

dropped or damaged in some
other way

We cannot accept any responsi­bility for incidences that occur
because safety information has
not been adhered to.

Teufel volume level measuring device

Do not rely on your ears. Equalising
your home cinema system works
much more precisely with the aid
of a volume measuring device. A
purchase that will last a lifetime!

All optional accessories can
easily be ordered as required,
e.g. from the accessories area
on our website:
www.teufel.eu

Optional accessories for the LT 2 + R

Here is an overview of the relevant accessories
available for your Teufel home cinema set.

Teufel Y adapter cable

If you want to connect
an appliance (e.g. MP3
player) that only has a
mini-jack output – and
the mini-jack input “PC”
is already occupied –

this cable is suitable for
connecting the appliance with the “VCR” or Aux”
cinch inputs. Available in three lengths.

Teufel casters

These black casters, cha­racterised by a particular­ly flat construction height,
make your Teufel subwoofer
mobile in no time at all. This
makes the back-breaking

carrying round of the sub­woofer when testing the ideal subwoofer position
a thing of the past. They are also very practical
when cleaning. These casters can be used instead
of the supplied resonance damper.Teufel speaker cable, 2 x 2.5 mm

2

This highly flexible copper wire
with transparent sheath and
marking to indicate polarity is
suitable for the satellite spea-

kers on your Concept S-system.
The 2 x 2.5 mm2 cable can be used for a length
of 15 metres. Due to a high number of customer
requests, our cable is precut to practical lengths
of 10 to 50 metres.

Oehlbach Red Opto optical fibre

These thin plastic lines are used to transfer digi-

tal data between the CD, MD
and amplifier/receiver and
between the laser disc and
DVD player and the AV ap­pliance. The cables are now
supplied with an adapter for

CD and MD Walkmans. The
black optical cable has a 5.5 mm diameter and is
the first choice for high quality home cinema and
THX systems.
A 0.5 m optical connection cable is already inclu­ded as standard. If you have to cover longer di­stances or simply want better quality, please use
our online shop to order the Oehlbach Red Opto
optical fibre cable. The Red Opto cable is available
in lengths of 0.5 to 6 metres.

Accessories (optional)

Teufel banana plug

These high-quality Teufel
all-round plugs enable you
to connect your speakers to
an amplifier or receiver in a
cost-effective and reliable

way. A stable screw grip
firmly holds all cables with a diameter up to 4 mm.
Permanently elastic spring contacts and genuine
gold-plating guarantees plug connections with
very low resistance. Supplied in pairs, one red
plug and the other black.

General information on configuration

Much more important than for a stereo system,
home cinema systems must observe certain set
up criteria in order to optimise the sound qual­ity when using a multichannel surround sound
system.

For home cinema systems, we recommend con­centrating on the area actually used – i.e. the
(part of the) room where the TV/screen and seats
are located. The TV/screen should be positioned
as centrally as possible to the listening location.

The recommended set-up (on the following pages)
represents the best possible arrangement for
perfect multichannel playback at home. Your
available space, your partner or furniture may
not always permit such ideal placement. Try to
meet as many requirements as possible. Small
variations are not a problem. The L2200/6 SWR of­fers options for compensating electronically for
any compromises in the set up. Generally spea­king, the following rule always applies: you can
always use our recommendations to experiment
with what works best acoustically and optically.
Let your ears (and eyes) decide!

Setting up the 5.1 configuration

Subwoofer

The location of the subwoofer is freely selectable
and does not affect the other speakers. Place­ment within a straight line between the two front
satellites is ideal. But you can also try it out at any
other location in the room. Thanks to its magne­tic screening, the woofer can also be placed near
the TV. We must, however, advise you not to use it
as a “TV table” as the subwoofer’s vibration may
cause the TV to “wander” – with potentially da­maging consequences to the appliance and users.
For ideal communication between the subwoofer
and remote control, it is essential for the front of
the subwoofer to be aimed towards the listener.

Centre

As the centre plays back all voice information, in­cluding the actors’ dialogues, the centre speaker
must be as central as possible to the listening po­sition or located above the TV/screen so that the
sound and image make up a harmonious unit.

SW Centre FrontFront

We recommend placing

the subwoofer in

the front grey area.

· LT 2 + R

Setting up the 5.1 configuration

We recommend placing
the subwoofer in
the front grey area.

We recommend placing
the rear speakers in
the rear grey area.

Select position area A or B.

Rear

The rear speakers should be set up to the left and
right either to the side or behind the listening
location – ideally at the same height as the front
speakers, e.g. on a shelf or directly on the wall.
The speakers can be fixed higher than the front
speakers (up to 2.10 m); but we advise you not to
locate them lower.

We always recommend that the distance between
the rear speakers and the listening location is
more than 1.00 m. But if you (have to) sit closer,
please ensure that the front of the speaker is
not pointing directly at you but rather angle the
speakers more into the room. Or create a greater
distance by positioning the speakers higher than

1.20m.

Rear

B

Rear

SW Centre FrontFront

Rear

B

Rear

Front

Using the old stereo tradition (distance to li­stener = distance between the left and right
speaker), the front speakers are set up next to
the TV/screen with the same distance to left and
right or fixed to the wall. If the speakers have to
be placed further out, you can easily turn them
inwards and towards the listening location.

The following applies if the front speakers are
fixed to the wall or placed on shelves: select a
set-up height of between 40 centimetres and

1.20 metres (lower edge). It is important that the
centre and front speakers are approximately in
a line, or possibly even on a slight arc to the TV.
Otherwise the homogeneity of the playback may
vary with run time differences. Setting the spea­kers up in this way allows them to deliver their full
sound potential.

Connection: Aerial · Speakers

* To be purchased

separately

Please ensure that no

individual exposed wire from

a cable comes into contact

with any free terminals, the
rear of the appliance or other
uninsulated cables (e.g. from

other speakers).

Please note:

Connecting the cables with

the incorrect phases can result

in thin sound, weak bass and

reduced stereo characteristics.

For multichannel surround

systems, too, it is important that

all speakers are connected with

the correct polarity in order to

ensure an appropriate three-

dimensional atmosphere and the

correct alignment of the sound.

Connecting the aerial

The use of the supplied aerials is essential as a
minimum requirement for disturbance-free re­ception. Please connect the aerials as shown in
the illustration.

A standard coaxial plug at the end of a coaxial
cable* (e.g. a cable connection) can be connected
directly with the FM coax input (in place of the
supplied auxiliary aerial).

Connecting the satellite speakers

The five satellite speakers for the treble and mid
ranges are connected via speaker cables to the re­levant speaker outputs front L/R, rear L/R and front
centre on the subwoofer. To do this, strip the ends of
the speaker cable (about 7 mm) and twist the cable.
The speakers and the fully active subwoofer have
corresponding [+] and [-] terminals. It is important
that you observe the correct polarity when con­necting the speakers: the plus pole of the speaker
to the plus pole of the subwoofer amplifier and the
minus pole of the speaker to the minus pole of the
subwoofer amplifier (“Speaker Output”). To do this,
press the clip and insert the ends of the cable.

Start-up

First ensure that all cables are connected as de­scribed above and insert the mains cable into the
socket.
Switch the main power switch [Power] on the back
to “On” to activate the 5.1 amplifier on the sub­woofer. The blue LED lamp lights up on the left of
the operation panel on the front of the subwoofer.
The “Input”, “Volume+” and “Volume-” buttons on
the operating panel have no (activated) function
(yet). The subwoofer starts operation when you
press “Standby”.

By pressing “Input” repeatedly you can activate
all inputs in succession: “Opt”, “Coax”, “VCR”, “Aux”,
“PC”, “Tuner”.
You can set the desired overall volume using the
“Volume [+] and [–]” buttons.

With the L2200/6SWR, it is possible to make all
settings using the remote control. To do this,
please first insert the batteries into the remote
control’s battery compartment as per the illus­tration:

If the appliance no longer reacts to the remote
control, even when it is used in direct proximity
to the subwoofer, please change the batteries.

Please note:

1) Do not combine new and old batteries

2) Do not use different types of batteries

3) Observe the polarity – see battery
compartment

For proper operation it is necessary to direct the
remote control towards the subwoofer from a di­stance not exceeding 5 metres and at a horizon­tal angle of no more than 30 degrees.

ĕThe remote control’s functions are explained

on pages 12/13.

Equalisation

Before familiarising yourself with the other func­tions of the appliance, it is necessary to set the
volume relationships of the five satellite speakers
and the bass channel for the bass speaker.

To do this, switch on the appliance using the “Po­wer” switch on the back.
The subwoofer goes onto standby when you press
the “Standby” button on the front operating pa­nel of the “Power” button on the remote control.
Make sure that no signal-emitting appliances,
such as DVD players, are active.

Increase the overall volume of the set to “70 dB”
via the central “Volume +” button on the remote
control u. This sets a kind of reference level. Make
sure you are in the best and most central place
possible for listening. Press the “Test” button {.
This activates a test tone that runs through the
five satellites and the subwoofer in sequence.
Now you can increase or decrease the level on
the remote control for the centre, the two rear
speakers and the subwoofer to the positions r
and p on the remote control until the volume of
these four speakers corresponds to the volume of
the two front speakers.

Equalisation by ear requires a few attempts and
does not always provide perfect results first
time. For perfect equalisation of the speakers
we recommend using a volume level measuring
device, as available in the Teufel shop. This device
is a purchase that will last a lifetime and allows
considerably more precise equalisation than the
ear. Bass levels in particular are often set too
loud – exact adjustment is only guaranteed using
a measuring device.
The volume setting of the subwoofer may be
slightly different when playing back music com­pared with home cinema sound, depending on
the recording quality and mixing. While a large

proportion of bass tones may often dominate in
effect-rich DVDs, the required level may be partly
unheard in the musical area (in particular if the
kit has been adjusted to optimal DVD reproduc­tion). Above all, personal taste is essential for
the best compromise between the two sources.
You can directly adjust the subwoofer level as re­quired using the buttons “Woofer [+] and [–]”r
on the remote control. Press the “Test” { button
again to complete the calibration process.

Please note!

After successfully completing

the test, please reduce

the volume from the 70 dB

setting used for testing.

Information

The selected settings

are retained even after the

device is switched off.

Setting up the surround system

Adjusting the time delay (“delay”)

In order for the appliance’s digital signal pro­cessor (DSP) to be able to convert Dolby signals
perfectly, it must be informed of the spatial posi­tioning of the individual speakers relative to each
other.
The C. Delay (Centre) P and S. Delay (Surround =
rear speaker) e buttons on the remote control
are used for this.

The correct delay time is calculated as follows:

Centre delay

1. Measure the distance between the listening

point and the front speakers

.

2. Measure the distance between the listening
point and the centre speaker.

3. Subtract the distance from the centre from
the distance from the front speakers.

4. Multiply the result by 3.
This gives you the delay time in milliseconds.

Example

Distance to the front speakers = 3.5 metres, di­stance to the centre speaker = 2.5 metres. Sub­traction of the distances equals 3.5 – 2.5 metres
= 1.0 metres. Multiplied by 3 this results in 3ms
delay time.

Information

The delay setting option for the
centre speaker is only provided in
the Dolby Digital and DTS listen
modes.

The following rule
of thumb applies:

In small rooms, up to 20 m², set
a delay value of 15 ms and in
medium-sized rooms (20–35 m²)
set a value of 20 ms.

Information

The setting option of the delay of
the rear speaker is only provided
in the Dolby Digital/DTS and
Dolby ProLogic II listen modes.

Surround delay of the rear speaker

1. Measure the distance between the listening

point and the front speakers.

2. Measure the distance between the listening
point and the rear speakers.

3. Subtract the distance of the front speakers
from the distance of the rear speakers.

4. Multiply the result by 3.
This gives you the delay time in milliseconds.

Example

Distance to the front speakers = 3.5 metres, di­stance to the rear speakers = 1.5 metres. Sub­traction of the distances equals 3.5 – 1.5 metres
= 2.0 metres. Multiplied by 3 this results in 6ms
time delay.
15 ms is added as a constant to the delay time
calculated by this method. For the example given
above, this results in: 6 ms + 15 ms constant =
21 ms delay time. As the L2200/6SWR permits set­tings in steps of 5, select the next possible value,
20 ms.

Frequently asked questions

“The subwoofer is buzzing”

These buzzing noises may be produced by con­nected appliances or faults in the power network.
Excessive buzzing is usually caused by one of the
following:

1. The subwoofer is connected to a different

power circuit from the rest of the equip­ment. Ensure that all linked appliances (in­cluding the PC if connected) are connected
to a single power circuit or plug.

2. The aerial connected to the equipment or TV

has a different ground potential to the socket.
To test this, simply remove all aerial cables from
the wall socket. If the interference stops, you
need a sheath current filter that is available
from electronics retailers (including the car hi­fi department). It is inserted between the aerial
socket and the LT2+R subwoofer.

3. A separately purchased mains filter, to which

all appliances must be connected, may be use­ful in eliminating the interference. Please ne­gotiate a right to return for the filter, in case
it does not lead to positive results.

4. Occasionally, a multiple socket strip proves to

be responsible for creating buzzing noises. To
test this, disconnect the plug strip and plug
the subwoofer’s mains plug directly into a
wall socket.

5. You can also try turning the mains plug

around and inserting it into the socket the
other way up, inasmuch as your mains plug/
socket allows this.

6. In order to better localise the cause of the buz-

zing, check whether the subwoofer operates
without buzzing on a power circuit in another
room (e.g. using an extension lead). In addition,
try disconnecting the cable connection from
the subwoofer to the connected appliances in
order to exclude the influence of connected
components.

“There is no sound – neither from the satel­lites nor from the subwoofer”

Please ensure that the power cable is firmly in­serted into the socket. If this is the case, please
check whether the blue “Standby” LED on the
Teufel subwoofer lights up after activating the
appliance by pressing the “Power” tip switch on
the rear; if this is not the case please contact our
service department.

“I hear no sound from the individual speaker
channels; other speaker channels work”

Please check whether all speaker cables – both
on the subwoofer rear and on the rear of the
satellite speakers – are firmly inserted into the
relevant sockets and that none of the individual,
uninsulated wires are in contact with each other.
Please also check the relevant channel setting
menus in the signal source appliance to be played
back (e.g. DVD player).

“The rear satellites and/or centre will not play
with stereo sources such as music CDs (e.g. via
PC or DVD player)”.

Switch the “Listen mode” on the remote control
to Dolby Prologic Music Modus = PL II.
Please also check the relevant channel setting
menus in the signal source appliance to be played
back (e.g. DVD player).

“The subwoofer is picking up additional radio/
interference signals”

In rare cases it may be possible to receive radio/
interference frequencies; this depends on the lo­cal environment. Please remove all cinch cables
from the subwoofer and check whether the in­terference still occurs. We recommend trying out
shorter, higher quality, shielded cinch connection
cables.

Care instructions and cleaning

To make sure you are able to enjoy your product
from Lautsprecher Teufel for a long time, please
note the following tips:
Do not expose the casing to direct sunlight.
Avoid extreme temperature differences and pro­tect your speakers from moisture.
When cleaning the speaker, only use a slightly
damp or dry cloth. Abrasive cleaners and products
that contain alcohol should be avoided. Remove
dust from the membrane very carefully with a dry
cloth.

“The subwoofer reacts to the remote control
of another device/another device reacts to
the decoder’s remote control”.

As there are no fundamental regulations on the
distribution of frequencies, each manufacturer
can work with the code of its choice. Unfortuna­tely, the fact that there may be occasional crosso­vers in individual cases cannot be prevented. This
is, however, not a fault in the subwoofer.
If, however, you have the freedom to choose ano­ther location and can locate the subwoofer out­side the range of the other appliance’s remote
control (i.e. not right next to the receiver) this
may reduce this problem, as the reception spec­tra may then no longer overlap.

“The subwoofer does not respond perfectly to
the remote control”

The batteries may have been inserted incorrectly
or they may be flat, so they may need to be in­serted correctly or replaced. Operation can be
impaired if the subwoofer is situated too far away
or in direct sunlight.

Active subwoofer

Speaker for bass playback, with integrated amplifier. Very deep
frequencies can only be played back with a large-volume spea­ker. To make sure that the front speakers can be kept as com­pact as possible, a separate subwoofer is used for bass tones. It
can be located unobtrusively in the living room: for instance,
behind the sofa or under a side table. The cut-off frequency
between the front speakers and the subwoofer depends on the
components used but is usually between 50 and 120 Her tz.

Auto On/Off function

The Auto On/Off function switches the subwoofer on as soon as
a signal is detected and off again a certain time after the last
signal was transferred (around 20 minutes).

Centre

Central speaker in the home cinema system. All dialogues are
played back via the centre. Therefore, good voice playback capa­bility is essential for the centre.

Cinema Set

All Teufel speaker systems that are supplied with three direct
front speakers and dipole effect speakers are also called a Ci­nema Set . In contrast, five direct speakers are called Concert
Sets.

Concert Set

All Teufel speaker systems with five direct satellites are called
Concert Sets. In contrast, Cinema Sets have three direct front
speakers and a dipole rear speaker.

Dipole

Dipole speakers emit sound in two directions. They are there­fore ideal rear speakers for your home cinema because their
emission characteristics imitate the speaker arrangement in
a commercial cinema. Cinemas always use multiple speakers for
the rear channels and their sound is distributed throughout
the whole room. Dipoles have been designed to emit sound indi­rectly into the room (i.e. not locatable), which is different from
direct emitters (see below).

Direct emitters

Direct emitters are conventional speakers that transport sound
to the listener in a direct line. In the home cinema, direct emit­ters are used generally to play back the three front channels; in
Concert Sets they are also located to the rear.

Dolby Digital/DTS Decoder

Electronic switching to divide up the digital multichannel si­gnals from the DVD into as many as seven individual signals.
Dolby Digital and DTS are two different sound formats, so two
different decoders are also required. AV receivers, DVD players
or corresponding sound cards usually have both decoders.

Frequency/cut-off frequency

This is where you stipulate the frequency used for playing back
sounds from the satellites or subwoofer. If, for example, you set
a cut-off frequency of 120 Hz, all frequencies above 120 Hz are
emitted by the satellites, frequencies under 120 Hz are played
by the subwoofer.

Level

The level controller on the subwoofer is used to adjust the vo­lume. For perfect playback, all speaker channels – incl. the sub­woofer – should be set such that the signals from the individual
speakers can be heard equally loudly at the listening location.

Phase

With the phase controller, you can adjust the subwoofer to the
satellites such that the speaker membranes vibrate in the same
direction in the cut-off frequency range. If the phase is set in­correctly, the bass may be weakened or cancelled. If the sub­woofer is located between the front speakers we recommend 0°,
for a position close to the listening location 180°. If the subwoo­fer is in another location, the “180°” setting can balance out the
reduced bass playback. Set the phase controller appropriately
to get the strongest bass playback.

Rear speaker

Effects and atmospheric sounds are played back via the rear

speakers (either ĕ dipoles or ĕ direct emitters). This gives a

greater spatial feel when playing back films and music.

Sub out

Output on the receiver/amplifier to connect an active subwoo­fer using a mono-cinch cable.

5.1/7.1 pre out

Pre-amplifier output on the re ceiver or output on the DVD
player. One analogue signal is provided for each channel via
cinch connection.

6.1/7.1 technology

Surround sound procedure that, in addition to the left and right
rear channel (and the relevant speakers), also uses a centrally
played back rear channel. Depending on the sound format, this
“rear centre” is embedded in the stereo signals for the left and
right rear channel (“matrixed”) and extracted for playback (e.g.
for THX® Surround EX, Dolby Digital EX) or transferred as an in­dependent signal. Instead of the dominant 5.1 technology, these
are therefore 6.1 sound formats. In practice, it has proven to
be beneficial for the sound to allow the rear centre to be pla­yed back by two centrally located rear speakers. AV technology
equipped with the necessary amplifiers and connections is there­fore called “7.1” although it only plays back a 6.1 signal.
