ENGLISH
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 therefore necessary to wear ear plugs or protective earphones.
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.
Cables connected to this transformer 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.
Refer to local regulations since there may be additional requirements about cable
characteristics.
