General Notes on Safety for Loudspeaker
Systems
Mounting systems may only be used for those loudspeaker
systems authorized by the manufacturer and only with the mounting
accessories specified by the manufacturer in the installation
instructions. Read and heed the manufacturer's installation
instructions. The indicated load-bearing capacity cannot be guaranteed
and the manufacturer will not be liable for damages in the event of
improper installation or the use of unauthorized mounting accessories.
The system's load-bearing capacity cannot be guaranteed and
the manufacturer will not be liable for damages in the event that
loudspeakers, mounting accessories, and connecting and attaching
components are modified in any way.
Components affecting safety may only be repaired by the manufacturer
or authorized agents, otherwise the operating permit will be voided.
Version 2.8 08/2019
Installation may be performed qualified personnel only, and
then only at pick-points with sufficient load-carrying capacity and
in compliance with local building regulations. Use only the mounting
hardware specified by the manufacturer in the installation instructions
(screws, anchors, etc.). Take all the precautions necessary to ensure
bolted connections and other threaded locking devices will not loosen.
Fixed and portable installations (in this case, speakers and
mounting accessories) must be secured by two independent safeties to
prevent them from falling. Safeties must be able to catch accessories
or parts that are loose or may become loose. Ensure compliance with
the given national regulations when using connecting, attaching,
and rigging devices. Factor potential dynamic forces (jerk) into the
equation when determining the proper size and load-bearing capacity
of safeties.
Be sure to observe speaker stands' maximum load-bearing
capacity. Note that for reasons of design and construction, most
speaker stands are approved to bear centric loads only; that is, the
speakers' mass has to be precisely centered and balanced. Ensure
speaker stands are set up stably and securely. Take appropriate added
measures to secure speaker stands, for example when:
- the floor or ground surface does not provide a stable, secure base.
- they are extended to heights that impede stability.
- high wind pressure may be expected.
- there is the risk that they may be knocked over by people.
Special measures may become necessary as precautions against
unsafe audience behavior. Do not set up speaker stands in evacuation
routes and emergency exits. Ensure corridors are wide enough and put
proper barriers and markings in place when setting speaker stands up
in passageways. Mounting and dismounting are especially hazardous
tasks. Use aids suitable for this purpose. Observe the given national
regulations when doing so.
Wear proper protection (in particular, a helmet,
gloves, and safety shoes) and use only suitable means of ascent
(ladders, scaffolds, etc.) during installation. Compliance with this
requirement is the sole responsibility of the company performing the
installation.
WARNING! After installation, inspect the system comprised
of the mounting fixtures and loudspeakers to ensure it is properly
secured.
The operator of loudspeaker systems (fixed or portable) must
regularly inspect or task a third party to regularly inspect all system
components in accordance with the given country's regulations and
have possible defects repaired immediately.
We also strongly recommend maintaining a logbook or the like to
document all inspections.
Also be sure to provide sufficient safety margins for the rigging points
used for flown systems. Observe the given national regulations when
doing so.
Professional loudspeaker systems can produce harmful
volume levels. Even prolonged exposure to seemingly harmless levels
(starting at about 95 dBA SPL) can cause permanent hearing damage!
Therefore we recommend that everyone who is exposed to high volume
levels produced by loudspeaker systems wears professional hearing
protection (earplugs or earmuffs).
