ENGLISH
moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
10. There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level
that leads to hearing loss is different from person to person and depends on the duration
of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices. When a
transducer capable of producing high sound levels is being used, it is therefore necessary
to wear ear plugs or protective earphones. See the manual technical specifications to know
the maximum sound pressure level.
IMPORTANT NOTES
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid
putting them close to:
- Equipment that produces high-intensity electromagnetic fields
- Power cables
- Loudspeaker lines.
The equipments considered in this manual can be used in electromagnetic environment E1
to E3 as specified on EN 55103-1/2: 2009.
