10. Mechanical and electrical fac tors 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 dierent 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 necessar y 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 eects 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
eects due to surrounding electro-magnetic elds) with a suitable section and a su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 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.
