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 technical specifications in the instruction manual for the maximum
sound pressure the loudspeaker is capable of producing.
IMPORTANT NOTES
To prevent the occurrence of noise on the cables that carry microphone
signals or line signals (for example, 0 dB), only use screened cables and
avoid running them in the vicinity of:
• equipment that produces high-intensity electromagnetic fields
(for example, high power transformers);
• mains cables;
• lines that supply loudspeakers.
