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 this user manual to know the maximum sound pressure
of each speaker.
12.
To ensure a correct sound reproduction, speaker phase is to be respected (speakers are
connected respecting the amplifier polarity).
This is important when speakers are installed adjacent one another, for instance, in the
same room.
Make sure speaker lines are not shorted before turning the amplifier on.
13. To prevent inductive effects from causing hum, noise and a bad system working,
speaker lines should not be laid together with other electric cables (mains), microphone or
line level signal cables connected to amplifier inputs.
14.
Speaker cables 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.
15. Install every speaker far away from any heat source.
16.
Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts. Use a dry cloth instead.
