Safety precautions |
|
|
|
|
|
|
|
|
Information regarding use of loudspeakers |
|
|
|
Never stand in the immediate vicinity of loudspeakers driven at a high |
|
WARNING! |
|
|
|
|
|
level. Professional loudspeaker systems are capable of causing a sound |
|
|
|
pressure level detrimental to human health. Seemingly non-critical |
|
|
|
sound levels (from approx. 95 dB SPL) can cause hearing damage if |
|
|
|
people are exposed to it over a long period. |
|
|
|
In order to prevent accidents when deploying loudspeakers on the |
|
|
|
ground or when flown, please take note of the following: |
|
|
|
When setting up the loudspeakers or loudspeaker stands, make sure |
|
|
|
they are standing on a firm surface. If you place several systems on top |
|
|
|
of one another, use straps to secure them against movement. |
|
|
|
Only use accessories which have been tested and approved by d&b for |
|
|
|
assembly and mobile deployment. Pay attention to the correct |
|
|
|
application and maximum load capacity of the accessories as detailed in |
|
|
|
our specific “Mounting instructions” or in our "Flying system and Rigging |
|
|
|
manuals". |
|
|
|
Ensure that all additional hardware, fixings and fasteners used for |
|
|
|
installation or mobile deployment are of an appropriate size and load |
|
|
|
safety factor. Pay attention to the manufacturers' instructions and to the |
|
|
|
relevant safety guidelines. |
|
|
|
Regularly check the loudspeaker housings and accessories for visible |
|
|
|
signs of wear and tear, and replace them when necessary. |
|
|
|
Regularly check all load bearing bolts in the mounting devices. |
|
|
|
Loudspeakers produce a static magnetic field even if they are not |
|
CAUTION! |
|
|
|
|
|
connected or are not in use. Therefore make sure when erecting and |
|
|
|
transporting loudspeakers that they are nowhere near equipment and |
|
|
|
objects which may be impaired or damaged by an external magnetic |
|
|
|
field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic |
|
|
|
data carriers (floppy disks, audio and video tapes, bank cards, etc.) is |
|
|
|
sufficient; a distance of more than 1 m (3 ft) may be necessary with |
|
|
|
computer and video monitors. |
