Safety guidelines
General note: Make sure to read this operating manual care-
fully and in its entirety. Before plugging in the units for the rst
time, make sure you have complied with all relevant safety and
operating instructions. Keep this operating manual in a safe
place so you can refer to it at a later date if necessary.
Always: If in doubt, consult the operating manual. Make sure
to comply with all instructions regarding the units' setup and
ongoing operation.
Cleaning: Avoid cleaning the units with domestic cleaning
agents, as these may scratch the surface. Just use a dr y cloth.
Before cleaning a unit, always unplug the power cable.
Humidity and sunlight: Never operate the unit in humid or
wet spaces, e.g., near a bath tub, shower, wash basin, drain, in
a damp basement, or near a swimming pool. Never expose the
loudspeaker to humidity, and avoid exposing it to direct sources
of sunlight.
Placement: Never mount the units loosely in a vehicle, on an unstable surface, on a loose stand, on unsuitable furniture, or with
insufcient bracing. The loudspeakers could topple and cause
personal injuries, which you will be liable for. Especially when
speaker cabinets are mounted on stands or placed on top of
TV sets/monitors, they may topple due to external stress (cable
being pulled, tripping over cable, accidental physical contact)
– even if they seem to be mounted quite securely. As a result
of their weight , toppling speaker cabinets can cause considerable damage, as well as becoming badly damaged themselves.
The same applies to undersized or unprofessionally installed
wall-mounting brackets, particularly on light walls. Always use
adequately sized wall brackets for mounting loudspeakers, and
ensure that the wall can withstand the stress. Never mount the
units near a heat source. This could be a heater or oven, but
also any other electrical device that heats up during operation
(e.g., amplier). Similarly, never place a heat source on top of the
loudspeakers, such as a fan heater or candles.
Ventilation: There are several ventilation slits and openings
in the unit's housing. These are designed to ensure reliable
operation and protect the unit from overheating. Never block
or cover the ventilation slits; do not place the unit on a soft
surface such as a bed, couch, carpet, etc., as this blocks the
ventilation slits in the bottom of the housing. Do not put any
newspapers, t ablecloths, etc., on top of the unit. Most importantly, do not cover up the heat sink of the amplier section
or expose it to direct sunlight . Conversely, you should generally
not attempt to provide additional cooling to the unit yourself.
This is not necessary.
Power source: Make sure to connect the subwoofer to a power
source that provides the correct voltage, i.e., the voltage indicated on the type plate. If you are unsure about the voltage
provided by your domestic power connection, please contact us
or your local electricity provider for advice. The unit does not
require earthing. When connecting to the mains power socket,
always use the supplied two-pole power cable. Under no circumstances should you modify the power cable, as it must comply
with the ofcial polarity and earthing regulations. Make sure to
plug the power cable only into a double-pole socket.
Cables: Lay all the cables ush with the oor and walls. Avoid
any loops in your cables that could cause people to trip up. Cable loops can also cause electrical interference and degrade the
sound quality. Make sure to lay your power cables out of reach
so that they are not stood on or squashed by heavy objects.
If you notice any cable damage, replace the cable. Pay special
attention to all plug connectors, the mains socket, and the subwoofer's connector panel. Regularly check all powered cables to
and from the loudspeakers for insulation issues and breakage. If
you detect a fault, immediately power down all connected units,
unplug the cables and replace the defective cable.
Disuse: During prolonged periods of disuse (holidays, etc.), always unplug the subwoofer from the mains socket.
Thunderstorms: In the event of a thunderstorm, switch off and
unplug the unit as soon as you can in order to avoid damage
from lightning strikes.
Overloading: Never overload your wall sockets, extension cables and multiboxes, or the integrated power sockets on your
electrical devices. Power overloads can cause short circuits
and res. Also avoid turning up the volume control excessively
on your amplier, particularly if you are also boosting the
bass frequencies (bass control, loudness button, bass boost
button, etc.).
Liquid and foreign substances: Liquids or other foreign substances should never get inside the unit, as they may interfere
with exposed live parts and cause short circuits or res. Absolutely avoid spilling any type of liquid onto the unit. In case of a
fault: Never attempt to repair the unit yourself. Always contact
our suppor t team rst and discuss the fault with them. If appropriate, they may give you instructions on how to clear the
fault. If this is not possible, send the unit directly to our service
address.
Transport: Take utmost care when transpor ting the unit, and
use a sack barrow if possible. Be aware that both the sack barrow and the unit can easily fall over as a result of sudden stopping or jolting (uneven ground, lurching movements, etc.).
Replacement parts: During the period of warranty,
Lautsprecher Teufel will supply all required replacement parts.
Your warranty will not be voided as long as you use Teufel spare
parts to replace any defective components.
Unusual noises: If any unusual noises occur during operation,
or if the sound gets distorted, immediately turn down the amplier volume to a level where the sound returns to normal.
Replacing the fuse:
Unplug the power cable before replacing the fuse. Make sure
that the replacement fuse has the same rating as the defective fuse.
Speaker volume: Excessive loudspeaker volume can cause irreversible hearing loss. The subwoofer may emit high sound
pressure levels very unexpectedly when it is suddenly triggered
into activity by a bass impulse (“Standby/Auto On” mode) – particularly if the unit is on full volume. As well as physical hearing
loss, also watch out for psychological stress caused by excessive
volume. Children and pets are particularly sensitive to noise. Always set the volume control of your audio system to a level that
is appropriate to the surroundings. When the system is playing
at high volume, do not stand too closely to the subwoofer and
never put your ears directly up to any of the loudspeakers.
Please read the following
safety guidelines
very carefully.
Packaging materials,
particularly plastic bags and
foils, should be kept out of
children's reach, as these can be
dangerous (e.g., risk
of suffocation). Never leave your
children alone with electrical
devices, as there is potentially
always a risk of electrical shock.
In case of an emergency:
Immediately disconnect the
unit's power plug from the
mains socket. In the following
cases, please contact one of our
service technicians:
4 Power plug or cable
is damaged
4 Liquid or other foreign
substances have entered the
interior of the unit
4 The unit has been directly
exposed to rain or another
type of liquid
4 The unit is inoperative
even though you have
followed all the operating
instructions

Speaker positions in the 5.1 configuration
Hint:
* Practice has shown that the
best bass imaging is achieved
if the subwoofer position is in
a relation of 1/3 or 2/3 to the
other speakers, i.e., not at the
centre of the front or side wall,
but offset towards one of them.
General notes on speaker placement
Thanks to its elegant and unobtrusive design, the
Teufel System 5 THX® Select loudspeaker set will
easily blend into your living room. In order to get
the best possible audio quality from your Teufel
system, however, there are a number of speaker
placement rules to consider; these apply particularly to home theatre use.
As a general guideline, any home theatre system
should be concentrated around the viewing area,
i.e., that part of the room that contains the TV/
screen and the main seating spots. If at all possible, the TV/screen should be placed centrally in
relation to the viewing/listening spots.
Our speaker placement suggestions, shown over
the next pages, are designed for the best possible
multi-channel sound reproduction in your home.
In the reality of your living room, of course, there
may be factors working against the suggested
placements. While our recommendations represent the audio purist's optimum layout, modern
AV receivers also offer a number of options to
electronically compensate for compromises in
speaker placement. Always remember:
Our recommendations are not the be-all-andend-all but a starting point. Ultimately, you will
know best what works in your room, both visually
and sonically. Trust your eyes – and your ears!
Centre
The centre speaker reproduces virtually all
spoken sound, including most dialogue. In relation to the main listening spot, place it centrally under or above the TV/screen. If you need
to position the centre speaker (M 550 FCR)
lower than 40 cm or higher than 1.20 m, angle it
horizontally towards the listening spot.
Front
The front speakers should be positioned the same
way as any conventional stereo speakers – forming
an equilateral triangle with the listener. In a home
theatre setup, the left and right front speakers
should be equidistant to the TV/screen, mounted on the wall or on speaker stands. The Teufel
M 550 FCR satellite speakers can be mounted
using Teufel's Multilock or L-Lock angle bracket.
The speaker cabinet has an M6 packing screw in
its base to fasten the cabinet to a wall mount.
This packing screw is similarly used to fasten the
cabinet to a speaker stand. For this system for
example the speaker stand M 550 P is suitable.
Speaker stands ensure that the satellite speakers are placed at the best possible height. If you
mount the spea-kers on the wall or on a bookshelf, make sure the speaker height is between 40
cm and 1.20 m. If these recommended values are
not practical in your listening environment and
you need to position the speakers higher or lower,
you should angle them towards the listening spot.
Teufel's Multilock wall mounts are designed for
just this purpose.
Finally, make sure that the centre speaker and the
two front speakers are positioned in a straight
line, or on a slight arc with the TV/screen. If the
distances between you and the speakers vary
signicantly, this will degrade the audio signal's
spatial imaging.
Make sure to align your speakers properly so they
sound as good as possible.
Subwoofer
At the recommended crossover frequency of
80 Hz, the subwoofer can be positioned in the
room very exibly without affecting the output
from the other loudspeakers. The ideal position
is somewhere along the axis between the two
front speakers,* but you should feel free to experiment with placing it anywhere you like. Simply
make sure that the front of the subwoofer (with
the speaker grille) can radiate freely towards the
centre of the room, i.e., it is not pointed directly
at a wall. If this cannot be avoided, make sure the
subwoofer is at least 0.50 m away from the wall.
Rear (Cinema Set)
About the rear speakers in the System 5 THX® Select Cinema Set: For the best home theatre results,
the M 550 D speakers should be run in dipole mode.
Dipole mode is selected on the speaker cabinet's
connection panel with a switch between the plus
and minus terminals (set to inwards). To determine
which response mode the switch is set to, simply
perform a quick listening test:
If the signal radiates out the back as well as the
front of the speaker cabinet, it is running in
“Dipole” mode. If there is no signal coming out
of the rear tweeters and woofers, it is running in
“Monopole” (direct) mode.
Attention:
In accordance with
THX
®
specications, these
loudspeakers are designed
for an optimal frequency
response with the speaker
grilles attached.
If the grilles are NOT
attached, this will increase
the speakers' treble response
and create an imbalance in the
frequency spectrum.
We recommend always leaving
the speaker grilles on the
speakers.

Speaker positions in the 5.1 configuration
We recommend
you place the rear speakers
somewhere in the
grey rear area.
Rear/side speaker placement option A Cinema
Set
The M 550 D dipole speakers should ideally be
mounted to the sides of the listening spot, at a
height of 1.40–2.10 m. The M 620 D speakers ship
with a simple integrated wall mount. With this
placement option, the dipole rear speakers radiate towards the TV/screen out the front (front
panel with Teufel logo) and towards the rear wall
out the back of the speaker cabinet. The distance
between the rear-radiating side of the dipole
speaker and the room's rear wall should be at
least 10 cm.
Rear speaker placement option B Cinema Set
You can also wall-mount the dipole speakers behind the listening spot, at a height of 1.40–2.10 m.
We recommend that you mount the M 550 D speaker cabinets with our L-Lock wall bracket, which
permits them to be angled horizontally. The ideal
angle for the dipole speakers is 45 degrees, which
means they can radiate towards the side wall out
the cabinet front and towards the rear wall out
the back. If the rear side channels are reected
off both the side and rear walls, this will create
the desired spatial diffusion. Note that the front
sides of the dipole speakers should be at least
10 cm removed from the room's side walls.

Setting up the AV receiver/amplifier
For the System 5 THX® Select with M 5500 SW
Active Subwoofer, set the “Speaker Setup” section of your AV receiver to “small” or “normal” (not
“large”). This ensures that the speakers receive
the right amount of signal, and that the subwoofer and front speakers have matching volumes.
Also in the receiver's “Speaker Setup” section
(Bass Management/Speaker Management), make
sure the subwoofer is set to “On”. Set the crossover frequency for the System 5 THX® Select
to 80 Hz.
Setting up the M 550 D dipole speakers
The M 550 D provides a speaker response switch,
which is located between the “plus” and “minus”
speaker terminals on the rear connection panel.
Two response modes are available: “Dipole” and
“Monopole”. For the speaker to run in “Dipole”
mode, set the switch to the inwards position. For
the speaker to run in “Monopole” mode, set the
switch to the outwards position. This disables
half of the M 550 D so it runs as a conventional
direct-radiating loudspeaker. To determine which
response mode the switch is set to, simply perform a quick listening test: If the signal radiates
out both sides of the speaker cabinet, it is running in “Dipole” mode. If there is no signal coming
out of the rear tweeters and woofers, it is running in “Monopole” (direct) mode. We recommend
using the dipole response mode in most settings.
Direct monopole response is only advisable in exceptional situations, e.g.:
1) The speaker cannot be placed close to a wall to
reect off.
2) Some multi-channel music recordings, e.g., on
SACD or DVD-Audio media, require a surround
sound setup where all the speakers have a distinct directionality.
Setting up the subwoofer
Set the subwoofer itself to “Full Range”. This
means that the phase and crossover frequency
are controlled by the AV receiver. Make sure
that the subwoofer's frequency control is set to
maximum.
Modern AV receivers determine the subwoofer's
phase automatically. This happens within the receiver's “Speaker Setup” utility, which analyses
the distance between the different speakers
and the listening spot. For this to work correctly,
the subwoofer's own phase switch needs to be
on “0°”.
If your system uses an older-model AV receiver
or another type of amplier without a setting for
the subwoofer distance,
you can use the subwoofer's phase switch
to manually adapt the phase to the other
speakers. The goal here is for all the bass
loudspeaker membranes that reproduce the
frequency range around the crossover frequency to vibrate in the same direction. If
the phase is set incorrectly, this may cause a
reduced bass response or even bass cancellations. If the subwoofer is positioned between
the front speakers, we recommend a phase setting of “0°”; if the subwoofer is positioned closer
to the listening spot, a phase of “180°” may be
more appropriate. Similarly, the “180°” setting
may help to eliminate bass cancellations if you
position the subwoofer in other areas of the
room. Always set the phase control to the position where the bass response is best.
The subwoofer's output setting may vary depending on usage, e.g., home theatre sound
system or music playback. Whereas an actionpacked DVD typically contains very dened sub
bass signals, many music-only sources do not.
This is especially noticeable if your system is
calibrated for optimum DVD playback. To nd
the best compromise between differing sound
sources, use your own subjective judgement.
Our recommendation is to determine the best
subwoofer volume gradually over time.
Avoid conguring the subwoofer volume automatically via your AV receiver's integrated room
analysis computer (advanced receivers only). Instead, set the subwoofer level provided in the
Bass Management/Speaker Management section
(“Speaker Setup”) to a high value, such as +4 to
+12 dB. This will guarantee that the subwoofer
activates itself at the right times when in “Auto
On/Standby” mode, and you can then use the subwoofer's own level control to experiment with different bass levels.

Y
Phase
This switch determines the phase relationship
between the subwoofer and the front/centre speakers. If the subwoofer is positioned in the speaker
setup as indicated on p. 9 (grey area of drawing), set
the phase to 0°. With other setups, the 180° setting
may produce better results.
U
Frequency
Use this control to set the crossover frequency between the subwoofer's bass signal and the bass frequencies of the other speakers. If you are using an
AV receiver, set the receiver's crossover frequency
to 80 Hz and turn the subwoofer's frequency control
to maximum (hard right).
I
Power
OFF means that the subwoofer is switched off; ON
means that it is switched on.
O
Power LED
When the subwoofer's mains power switch I is
off, the power LED is off. When the subwoofer's
mains power switch I is on, the power LED lights
up red or green, depending on the position of the
Power Function switch Q.
When the subwoofer is permanently active
(= Power Function Q ON), the power LED is green.
When the subwoofer is in standby mode (Power
Function Q AUTO), the power LED is red. After
the subwoofer is triggered into activity, the LED
changes to green. After the subwoofer switches
itself off after 20 minutes of inactivity, the LED is
red again. When the Power Function switch Q is
set to OFF, the LED is red.
P Voltage selector
This switch adapts the internal amplier to the
local mains voltage. NEVER set this to any other
value than the standard local voltage value. In
Germany, the correct position is “220 – 240V”.
{ Fuse
This is where the mains power fuse is located.
Q
Power Function (automatic)
OFF means that the subwoofer is switched off; ON
means that it is switched on. AUTO means that the
subwoofer is operational but is only activated once
it receives an audio signal. In “AUTO” mode, the subwoofer automatically switches to standby after 20
minutes of inactivity.
W
Line Input
Connect the AV receiver's “Sub Out” to the subwoofer's “Line Input” using a mono RCA cable (optionally
with an additional Y adapter).
E
Line Output
Here you can connect a second subwoofer for added
bass or to compensate for resonant frequencies in
the room.
R Low Pass – Full Range
With the switch on “LOW PASS”, the built-in controls
for “Phase” and “Frequency” are
activated.
With the switch on “FULL RANGE” (recommended
setting), these parameters
are controlled by the AV receiver.
T
Level
Use the “LEVEL” control to adjust the subwoofer's
volume. In the receiver's bass management section, set the bass level to a high value, i.e., between +6 and +12 dB. Next, set the subwoofer's
level control to 1/4. While the AV receiver is outputting its white noise setup signal, slowly turn
up the subwoofer level to the desired volume.

The subwoofer is connected to a different
electrical circuit
than the other components.
Make sure that all the connected devices (including any computers) are powered from the
same electrical circuit, i.e., the same mains
socket.
2. The antenna connected to the audio sys-
tem or T V
has a different ground potential to
the antenna socket. To test this, simply discon-
nect all the antenna cables from the wall socket.
If this makes the hum disappear, you will need a
ground breaker (available from most electronics
stores). Simply insert the ground breaker between the antenna socket and the TV/receiver.
3. A line lter (to be purchased separately)
can
also be useful for hum removal. Note that you
will need to connect all your electrical devices
to the line lter. Make sure you can return the
line lter for a refund if it does not produce
the desired results.
4. Some types of power multiboxes are also
known to produce hum. Try eliminating your
multibox and plug the subwoofer's power cable
directly into the mains socket.
5. If possible: Unplug the mains cable, rotate
the connector plug by 180°,
and plug it back
into the mains socket.
6. If you have trouble locating the source of the
hum,
check whether the subwoofer is less noisy
when you plug it into the mains connection in
another room (e.g., using an extension cable).
Also, try disconnecting the subwoofer's RCA
cable from the receiver
to see whether the hum
is caused by one of the other connected
audio
devices.
