5. INSTALLATION
Roll the PA-system to the desired installation area and carefully turn it onto the standing feet.
This PA-system must only be installed at a solid, plane, anti-slip, vibration-free, oscilation-free and fire-
resistant location.
Before installing the system, make sure that the installation area can hold a minimum point load of 5 times
the system's load (e.g. weight 20 kg - point load 100 kg).
This PA-system must never be installed higher than 100 cm.
Make sure that the power switch is set to "OFF". Before you connect the devices, all units have to be
switched off and alll level-controls are set to "0".
5.1 Installing and orienting the PA-system
When installing the speaker-system on e.g. a stage, microphones and turntables should always be located
behind the speaker-systems. In this way, you can avoid dangerous and unpleasant feedbacks. If you cannot
install the speaker-systems this way, the microphones and turntables should be located as far away as
possible from the speaker-systems. When using the speaker-system as monitor-system make sure to avoid
feedbacks.
The speaker-systems of a PA-system are normally located left and right to the stage. Do not install the
speaker-systems on the stage, but rather on appropriate tables or platforms in front of the stage.
In order to produce a clear sound, the speaker-systems should be installed in a way that they throw the
sound over the audience's heads. A Full Range speaker-system should be installed at listeners' eye level.
Please refer to the safety instructions under Installation.
5.2 Installation on a stand or speaker stand
In order to throw the sound over the audience's heads you may use a stand or speaker stand to lift the PA-
system.
The speaker-system may only be installed on a stand or speaker stand if the original speaker-system is
equipped with an appropriate flange.
Stands or satellite systems must only be installed on a plane area with a maximum inclination angle of 5°.
Caution:
Speaker-systems installed on stands or satellite systems may cause severe injuries when
crashing!
When using stands or satellite systems under the influence of horizontal forces, e.g. through wind, the
standing safety can be impaired. This is why additional safety measures like attaching ballast weights have
to be taken.
If inclined tension cables or prolonged outriggers are used, the area of danger has to be marked or even be
blocked.
Before lifting or lowering the telescopic tubes, you must alway block a safety area around the stand or
satellite system. This safety area must have a diameter of 1.5 times the maximum height.
Lifted telescopic tubes always have to be secured with a secondary securing!
The total weight of the installation (=total weight of all individual parts) must never exceed the maximum load
of the installation area.
The stand has to be installed out of the reach of people.
An unintended movement of the load has to be avoided - also in case of fire!
