Operation
Operate the speaker-system only after having familiarized with its functions. Do not permit operation by
persons not qualified for operating the speaker-system. Most damages are the result of unprofessional
operation!
By operating speaker-systems with an amplifier, you can produce excessive sound pressure levels that may
lead to permanent hearing loss. Please refer to the explanations under "Legal instructions".
WARNING!
Speaker-systems must only be operated by instructed persons.
Danger of Life due to crashing speaker-systems or hearing loss due to excessive sound pressure
levels! The different local conditions have to be considered in terms of safety rules.
Please note:
only connect Line-Level signals to this active system. Never connect the inputs with the
speaker-outputs of a power amplifier!
When operating the speaker-system, please make sure that the loudspeakers always sound well. When
distorsions can be heard, either the amplifier or the loudspeaker 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 speaker-systems are destroyed by overload, the guarantee becomes void.
This speaker-system can be installed on top of a subwoofer (satellite system), on a speaker stand, an
appropriate stand or an appropriate wall-mounting. The carrying capacity of the distance-tube, the speaker
stand, the stand or the wall-mounting must never be exceeded.

3.1 Legal instructions
Operating an amplification system can produce extremely high noise levels that may cause a permanent
hearing loss. The legal instructions for using an amplification system vary from country to country. The user
must always inform himself on the legal instructions valid in his country and apply them to his situation.
Always monitor the sound pressure level when operating an amplification system in discotheques, concerts
etc. Never exceed the permissible noise level exposures as specified by your authorities. The monitoring of
the noise levels must be documented in an appropriate way.
