6. INSTALLATION
The speaker system can be set up as desired. The location must be solid, plane, anti-slip, vibration-free,
oscillation-free, and fire-resistant. The installation area must hold a minimum point load of 5 times the
system's load (e.g. weight 20 kg - point load 100 kg). The speaker system must never be installed higher
than 100 cm without secondary attachment.
The speaker system features two transportation handles. It should be carried without force by two persons of
the same size. Carrying the speaker system by one person should be avoided as the high weight and the
strain could lead to back damages and torsions. Please note that all speaker systems with more than 25 kg
weight must be transported with two persons.
Installing and orienting the speaker 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 feedback. 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
feedback.
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.
Loudspeaker combinations need to be installed bass-middle-high (from bottom to top). Make sure that the
membranes of all speakers are in one line vertically and horizontally. Only in this way all frequency ranges
are produced at the same time and without any time or phase delays.
Always install the speaker systems in a way that a minimum distance of three meters to the audience is kept.
This is the only way to avoid hearing damage for unreasonable listeners. Block the area in front of the
speaker systems with appropriate means.
