RCF HDL 15-AS [4/20] Operating precautions

ENGLISH

recommended by the manufacturer. The equipment / support / trolley assembly must be

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.
