5. INSTALLATION
This PA-system must only be installed at a solid, plane, anti-slip, vibration-free, oscillation-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 all 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.
