Safety guidelines
General note:
Make sure to read this operating manual care-
fully and in its entirety. Before plugging in the units for the first
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 dry cloth.
Before cleaning a unit, always unplug the power cable.
Humidity and sunlight:
Never expose the units to humidity
or moisture. Protect them from excessive humidity and do not
place them in environments such as damp basements. Avoid
operating the units near wet environments such as bathtubs,
shower basins, hand basins, drains, swimming pools, etc. Also,
avoid placing the units in areas that are permanently exposed
to direct sunlight.
Placement:
Never mount the units loosely in a vehicle, on an un-
stable surface, on a loose stand, on unsuitable furniture, or with
insufficient 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 consider-
able 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., amplifier). 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, tablecloths, etc., on top of the unit. Most impor-
tantly, do not cover up the heatsink of the amplifier 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 in-
dicated 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 circum-
stances should you modify the power cable, as it must comply
with the official polarity and earthing regulations. Make sure to
plug the power cable only into a double-pole socket.
Cables:
Lay all the cables flush with the floor and walls. Avoid
any loops in your cables that could cause people to trip up. Ca-
ble 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 sub-
woofer'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.), al-
ways 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 ca-
bles and multiboxes, or the integrated power sockets on your
electrical devices. Power overloads can cause short circuits
and fires. Also avoid turning up the volume control excessively
on your amplifier (higher than 3/4), 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 sub-
stances should never get inside the unit, as they may interfere
with exposed live parts and cause short circuits or fires. Abso-
lutely avoid spilling any type of liquid onto the unit.
In case of a fault,
never attempt to repair the unit yourself. Al-
ways contact our support team first 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 transporting the unit, and
use a sack barrow if possible. Be aware that both the sack bar-
row and the unit can easily fall over as a result of sudden stop-
ping or jolting (uneven ground, lurching movements, etc.).
Replacement parts:
During the period of warranty, Laut-
sprecher 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 am-
plifier 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 defec-
tive fuse.
Speaker volume:
Excessive loudspeaker volume can cause ir-
reversible 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) – par-
ticularly 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. Al-
ways 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 sa-
fety guidelines very carefully.
Packaging materials,
particularly plastic bags and
foils, should be kept out of
childrens' 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:
