connecting cables between the pre-amplifier and the amplifier (switch off components before). Now adjust
the volume with the gain controls CH-1 and CH-2.
Caution!
Increase the level of each channel only so far that the CLIP-LED lights up shortly. Thus, you avoid
that the output signal is distorted and your speakers are damaged.
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.
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
The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a
skilled person once a year.
The following points have to be considered during the inspection:
1) All screws used for installing the speaker-systems or parts of the speaker-system have to be tighly
connected and must not be corroded.
2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension,
trussing).
3) The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or
sediments. Further instructions depending on the installation spot and usage have to be adhered by a
skilled installer and any safety problems have to be removed.
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 servicable 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 distortet, the speaker-systeem 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 loosended 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.
