ENGLISH

10. Mechanical and electrical factors need 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

necessary to wear ear plugs or protective earphones.

See the technical specications in the instruction manual for the maximum sound

pressure the loudspeaker is capable of producing.

12. To ensure a correct sound reproduction, loudspeaker phase is to be respected

(loudspeakers are connected respecting the amplier polarity).

13. To prevent inductive effects from causing hum, noise and a bad system working,

loudspeaker lines should not be laid together with other electric cables (mains),

microphone or line level signal cables connected to amplier inputs.

14. The loudspeaker cable shall have wires (twisted, if possible, to reduce inductive

effects due to surrounding electro-magnetic elds) with a suitable section and a

sufcient electrical insulation.

15. Do NOT connect the loudspeaker low impedance input to 100 V constant voltage

lines.

16. Install this loudspeaker far from any heat source.

17. Do not overload the loudspeaker with too much power.

18. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the

external parts of this product. Use a dry cloth.
