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). This is important when

loudspeakers are installed adjacent one another, for instance, in the same room.

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. Refer to local regulations since there may be additional requirements

about cable characteristics.

15. Do NOT connect the loudspeaker low impedance (8 Ω) input to 70 / 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.
