INSTALLATION
The speaker can be fastened to the installation area via the wall holder. 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). The installation of the device has to be built and constructed in a way that it can hold 5
times the weight for 1 hour without any harming deformation.
When using this speaker system in public or industrial areas, a series of safety instructions have to be
followed that this manual can only give in part. The operator must therefore inform himself on the current
safety instructions and consider them.
Make sure that the area below the installation place is blocked when installing, uninstalling or servicing the
fixture. When installing, uninstalling or servicing the speaker staying in the area below the installation place,
on bridges, under high working places and other endangered areas is forbidden. The device should be
installed outside areas where persons may walk by or be seated.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert before taking into operation for the first time and after changes before taking into operation another
time.
IMPORTANT! OVERHEAD INSTALLATION REQUIRES EXTENSIVE EXPERIENCE, including (but not
limited to) calculating working load limits, installation material being used, and periodic safety inspection of
all installation material and the device. If you lack these qualifications, do not attempt the installation yourself,
but instead use a professional structural installer. Improper installation can result in bodily injury and or
damage to property.
Devices in hanging installations may cause severe injuries when crashing down! If you have doubts
concerning the safety of a possible installation, do NOT install the device!
Attachment
The device must only be installed absolutely planar at a vibration-free, oscillation-free and fire-resistant
location. Make sure that the device is installed absolutely planar by using a water level.
The device must be installed out of the reach of people.
This device is only allowed for an installation via the installation equipment. In order to safeguard sufficient
ventilation, leave 50 cm of free space around the device.
The durability of the installation depends very much on the material used at the installation area (building
material) such as wood, concrete, gas concrete, brick etc. This is why the fixing material must be chosen to
suit the wall material. Always ask a specialist for the correct plug/screw combination indicating the maximum
load and the building material.
Choosing an Appropriate Amplifier
Connect this speaker system to an appropriate power amplifier, otherwise damage may occur. If several
speakers are connected the impedance decreases correspondingly. Please make sure that the power
amplifier is qualified for your intended use.
Example for the calculation number of speakers/impedance.
Number of speakers
1 speaker at 8 Ω
2 speakers at 8 Ω each 4 Ω (parallel)
2 speakers at 8 Ω each 16 Ω (in line)
3 speakers at 8 Ω each 2.66 Ω (parallel)
3 speakers at 8 Ω each 24 Ω (in line)
4 speakers at 8 Ω each 2 Ω (parallel)
The input impedance of the speaker systems should at least be the same or even higher than the output
impedance of the amplifier.
