ENGLISH
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 dura-
tion of exposure. To prevent potentially dangerous exposure to high levels of acoustic pres-
sure, 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.
