ENGLISH
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 therefore 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 musical 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 with a suitable section (twisted, if possible, to reduce
inductive effects due to surrounding electro-magnetic fields) and a sufficient electrical insulation.
OPERATING PRECAUTIONS
• Install this loudspeaker far from any heat source.
• Do not overload this product for extended periods of time.
• Never force the control elements (keys, knobs, etc. ).
• Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external
parts of this product.
• If the speaker is used in particulary cold places, drive it with a low signal for 5-10 minutes before
using it at maximum power.
