The subwoofer is not working
If the power LED on the
front panel does not light up
after switching on the unit,
replace the fuse (see page 11,
point
T
).
If the power LED lights up,
set the subwoofer volume
level to “Min”, unplug the subwoofer's RCA cable
from the amplifier, turn up the subwoofer's vol-
ume level slightly and touch the tip of the RCA
connector (the pin protruding from the middle)
with your finger. If this produces a hum or crackle,
the fault is with the amplifier or the amplifier set-
tings. If the subwoofer remains completely silent,
please contact our support team.
The subwoofer is making a humming noise
Hum may be caused by any connected audio de-
vice as well as by problems with the mains power.
In most cases, excessive hum is caused by one of
the following:
1.
The subwoofer is connected to a different
electrical circuit than the other components.
Make sure that all the connected devices (in-
cluding any computers) are powered from the
same electrical circuit, i.e., the same mains
socket.
2.
The antenna connected to the audio system
or TV has a different ground potential than
the antenna socket. To test this, simply dis-
connect all the antenna cables from the wall
socket. If this makes the hum disappear, you
will need a ground breaker (available at most
electronics stores). Simply insert the ground
breaker between the antenna socket and the
TV/receiver.
3.
A line filter (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 filter. Make sure you can return the
line filter 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 ca-
ble 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 connec-
tion 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 con-
nected devices.

Cleaning
Please take note of the following guidelines to
protect your Teufel loudspeakers:
Avoid placing the speaker cabinets in direct sun-
light. Avoid extreme temperature fluctuations
and protect your loudspeakers against humidity.
When cleaning the speaker cabinets, only use dry
or moist cloths. Never use abrasive or alcohol-
based cleaning products. If you need to clean a
speaker membrane, do so very carefully using a
dry cloth. Before cleaning a unit, always unplug
the power cable.
