INSTALLATION
Setup
The speaker systems can be placed 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 speakers must never be installed higher than 100 cm without secondary attachment.
•
This speaker system may only be installed on top of another speaker system if both systems are lashed up
with each other via appropriate clamping belts and protected against flipping over.
•
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.
Stands/Satellite Systems
It is possible to put the speaker systems onto a PA speaker stand via the stand flange on the lower side or
on top of a subwoofer system via a distance tube.
•
Stands must only be installed on a plane area with a maximum inclination angle of 5°.
•
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 always 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 speakers have to be installed out of the reach of people. An unintended movement of the load has to
be avoided - also in case of fire!
•
The installer is responsible for adhering to the carrying capacity given by the manufacturer, the safety
requirements and the qualification of possible co-workers.
•
When people are located below the load, all necessary safety measures have to be taken in order to avoid
injury.
•
The personnel have to be instructed on the content of the user manual and on the dangers related with
operating stands.
•
Depending upon the individual installation spot, all necessary measures against movement and for
securing the standing safety have to be created.
•
The installation is only allowed on carrying areas. In some cases, an appropriate substructure, e.g. via a
balancing foot, has to be created. When choosing the installation material, optimum dimensions have to be
chosen in order to secure maximum safety.
•
Speaker systems installed on stands or satellite systems may cause severe injuries when crashing! If
installing on slippery surfaces, the legs must be secured with screws or nails via the provided holes or an
anti-slippery mat has to be used.
Making the Connections
To avoid interfering noise, switch off the speaker system or set the output controls to minimum prior to
connecting and disconnecting equipment. Be sure to use only high-grade cables.
•
Feed the audio input signal via XLR or 6.3 mm plug to the jacks of channel CH 1 and CH 2. These inputs
allow to connect audio units with line level (e.g. mixer or CD player). When connecting line level devices,
make sure that the MIC/LINE level switch is disengaged. Alternatively, you can connect microphones to
these inputs. In this case, depress the MIC/LINE level switch. Note: The channel CH 2 input jacks of
models XKB-208A and 210A are designed for line level devices only.
•
At the XLR output MIX OUT the master signal of all channels is available. This output allows connecting
e.g. the input of another active speaker system for additional PA applications.
•
Finally, connect the supplied power supply cable to the corresponding input and the mains plug to an
outlet.
