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.
