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.
8.1 System-test
Connect your PA-system with the mains.
With the Power-switch, you can switch the PA-system on and off. When switching the device on, the Power-
LED is illuminated.
8.2 Adjusting the signal levels
As soon as the Audio-signals are present the signal levels are reproduced by the speakers. You can adjust
the level of the input signals via the respective controls
8.3 Reverb-effect
When choosing the Reverb-effect, an echo is added to the original sound. The effect depth can be adjusted
via the Reverb-control.
8.4 Connecting one PA-system to another
In order to reach a more powerful sound, you may wish to install one PA-system to the left and one to the
right.
If you will use more signal sources, select one PA-system as master-system and connect your signal
sources with the respective inputs.
Connect the Line Out-socket of the master-system with the Main In-socket of the second system.

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 tightly
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 serviceable parts inside the device except for the fuse. Maintenance and service operations are
