1.1. Information regarding the use of loudspeakers

Potential risk of personal injury
Never stand in the immediate vicinity of loudspeakers driven at a

high 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.

Potential risk of material damage
Loudspeakers produce a static magnetic field even if they are not

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.
