Frequently asked questions
“The subwoofer is buzzing”
These buzzing noises may be produced by con-
nected devices 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 equip-
ment. Ensure that all linked devices (includ-
ing 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 (also in the car hi-fi
department). It is inserted between the aerial
socket and the Concept S SW+R subwoofer..
3.
A separately purchased mains filter, to which
all utilised devices 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 generating buzzing noises.
To test this, disconnect the socket 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.
To pinpoint the source of the buzzing more ac-
curately, check whether the subwoofer works
without buzzing with a different electricity
supply in another room (e.g. using an extension
lead). In addition, try disconnecting the cable
connection from the subwoofer to the connect-
ed devices in order to exclude the influence of
connected components.
“There is no sound – neither from the satel-
lites nor from the subwoofer”
Please ensure that the power cable is firmly in
-
serted into the socket. If it is, please check
whether the blue “Standby” LED on the Teufel
subwoofer lights up after you have activated the
device using the “Power” flip switch at the rear.
If it doesn’t, please contact our service depart-
ment.
“I cannot hear any sound from the individual
speaker channels, although other speaker
channels are working”
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 observe the corresponding channel
setting menus in the reproducing signal source
device (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 observe the corresponding channel
setting menus in the reproducing signal source
device (e.g. = DVD player).
“The subwoofer is picking up additional radio/
interference signals”
In very rare cases it is possible to receive radio/
interference frequencies, but it depends on local
conditions. Please remove all cinch cables from
the subwoofer and check whether the inter-
ference still occurs. We recommend trying out
shorter, higher quality, shielded cinch connection
cables.
