remove the subwoofer cinch cable from the am-

cinch thermal resistor of the cinch cable (inside)
with your finger. If you can hear buzzing or crack-
ling, the defect is in the amplifier or its settings. If
the subwoofer remains silent in both cases, please
contact our service department.
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

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
buzzing, check whether the subwoofer ope-
rates without buzzing on a power circuit in
another room. In addition, try disconnecting
the cinch connection from the subwoofer to
the receiver in order to exclude the influ-
ence of connected components.
The subwoofer does not switch on automati-
cally when in "Auto ON" mode
Some AV receivers issue the bass signals via the
subwoofer pre-amplifier output so quietly that
the subwoofer does not start automatically, as
the weak signal is not interpreted as a switch-on
request. To make sure the subwoofer switches on
and off correctly in auto mode, we recommend
turning the level control on the subwoofer only to
"55" and increasing the output level for the sub in
the receiver's speaker set-up – sometimes up to
the maximum (+10 dB or +12 dB). The subwoofer
should then work perfectly. If not, you can change
the setting to permanently "On" .
The subwoofer reacts to the remote control of
another appliance
As there are no fundamental regulations on the
distribution of frequencies, each manufacturer
can work with the code of its choice. Unfortu-
nately, occasional crossovers in individual cases
cannot be prevented. This is, however, not a fault
in the subwoofer. If there are incompatibilities,
you can try covering the subwoofer's receiving
diode with opaque adhesive tape. If, however, you
have the freedom to choose another location and
can locate the subwoofer outside the range of
the receiver's remote control (i.e. not right next
to the receiver) this may reduce the problem, as
the reception spectra may then no longer over-
lap.
extreme temperature differences and protect
your speakers from moisture. When cleaning the
speaker, only use a slightly damp or dry cloth. Ab-
rasive cleaners and products that contain alcohol
should be avoided. Remove dust from the memb-
rane very carefully with a dry cloth.
