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.
