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.
