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 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.

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

connected respecting the ampliﬁer 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 ampliﬁer inputs.

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

due to surrounding electro-magnetic ﬁelds) with a suitable section and a sufﬁcient 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.
