3.0 - Safety Considerations
General Considerations in use
Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure
that you read this section fully, and contact EM Acoustics or your local dealer should you
be in any doubt over correct operation procedures.
Personal Injury
Never stand in the immediate vicinity of loudspeakers when in use at high level.
Professional loudspeaker systems are capable of producing sound pressure levels which
can cause permanent damage to human hearing. Levels in excess of 90dB can cause
hearing damage if people are exposed to them over a long period of time, so care and
attention must be used for both staff and audience members.
When deploying loudspeaker systems on the ground or when flown, please take careful
note of the following important safety considerations:
•
Only use accessories and flying hardware supplied or approved by EM Acoustics for
flying or transporting loudspeaker systems. Pay close attention to specific
instructions, especially those considering maximum load capabilities as detailed in
the appropriate user manuals or on the legend labels on the accessories
themselves.
•
Ensure all additional accessories, fasteners and secondary safeties are of an
appropriate size, working load limit and safety factor.
•
All loudspeakers and accessories should be regularly inspected for signs of wear
and tear, and any damaged parts should be replaced.
•
All load bearing parts and assembly bolts on accessories should be regularly
checked to ensure they are tight and not worn.
Stand Mounting
When mounting loudspeakers on a stand, please take note of the following important
considerations:
•
Ensure your stand height is locked off and the tripod legs are positioned so as to
be stable.
•
Check the weight loading of your stands before attempting to mount the
loudspeaker.
•
Do not stack a second loudspeaker on top of the stand-mounted one.
•
Ensure cables are run so as to leave enough slack to enable neat wiring, and thus
reduce the risk of the speaker being pulled over. Loose cables should be covered
or taped down wherever possible to reduce trip hazards.
•
If stands are being used outdoors, it may be necessary to add ballast to the base
of the stand to prevent it toppling over.
•
When using poles on top of subwoofer systems, please observe similar precautions.
