OPERATION
After having connected your amplifier to the mains, turn all level controls counterclockwise to the minimum
position. The last device to be switched on is the amplifier. Now adjust the volume with the level controls.
Caution! Always make sure that the output signal is not distorted and that your speakers will not get
damaged. During operation, please make sure the speaker always sounds well. When distortions can be
heard, either the amplifier or the speaker is overloaded. Overloads can quickly lead to amplifier or speaker
damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. When
speakers are destroyed by overload, the guarantee becomes void. Always check the sound pressure level
with a meter in order to keep to the threshold. If you want to switch off the system, switch off the amplifier
first and then the pre-amplifiers in order to avoid acoustic shocks on the speakers.

CLEANING AND MAINTENANCE
We recommend a frequent cleaning of the speaker system. Please use a soft lint-free and moistened cloth.
Never use alcohol or solvents!
There are no serviceable parts inside the speaker system. Maintenance and service operations are only to
be carried out by authorized dealers.
If the speaker system distorts, one of the loudspeakers may be defective. Test the speaker system once
more with another amplifier. If the sound remains distorted, the speaker-system should not be operated any
more in order to prevent further damage. Please contact your dealer.
If clacking sounds are heard from the speaker system, screws may have loosened due to the continuous
vibrations. The speaker system should be checked by a specialist. Especially for public use, the speaker
system should be checked before every operation so that the speaker system and the speakers in the
systems are always well fixed.
Should you need any spare parts, please use genuine parts.
Should you have further questions, please contact your dealer.
