SAFETY INFORMATION
Install the speakers in order to achieve the best possible stability. If it’s the case, adjust points/feet supports. Avoid placing heavy objects
on the speaker as they can compromise its stability.
In case the speaker is placed on a surface other than the suggested stands (ex. shelves, bookcases, TV supports, etc.) or directly the
floor, firstly check that it can support the weight of the speaker(s). Also check that there is enough friction between the speaker and the
surface in order to avoid any movement caused through vibrations whilst in use. Where needed rubber adhesive feet can be purchased
from all good hardware stores.
Do not put any objects containing water or other liquid/liquefiable substance on the speaker system.
Follow the connection diagram suggested in the instructions manual. Remember that the parallel connection of two or more speakers can
damage your amplifier. If in doubt, contact your dealer.
Whilst the audio system is operative at high volumes avoid staying in close proximity to the speaker system. This can cause permanent
damage to your hearing! Children should maintain a safe distance from the speaker system of at least 50cm.
The speakers produce an electromagnetic field which is harmless to humans and pets, but they can cause disturbances in the correct
functioning of electronic equipment such as monitors or cathode tube TVs when placed in close proximity. If this occurs, simply and slowly
distance one from the other. As a further precaution, it is not advisable to place credit cards or similar magnetically read objects on top
of the speaker system.
The technology behind the functioning of the speakers is based on the principles of electromagnetism, and thus the user should avoid
operating equipment that generates strong electromagnetic fields as these could affect the correct functioning of the speaker. Avoid
placing transmitting devices such as mobile phones, cordless phones, intercom systems etc. on top of the speaker systems.
Do not directly connect to a constant voltage (100V, 70.7V or similar) sound distribution system. This could have as a consequence a
serious system’s overload with probable damages to the loudspeaker system and/or the amplifier unit.
Keep amplifier-speaker connection and power (mains) cables separate. Mains cables carry an alternating voltage at a frequency of 50Hz
(60Hz in Japan and the USA) and an intensity that can be high, and thus produce an electromagnetic field even at audio frequency around
them. In the case of coupling of these two types of cables an annoying hum noise will be perceived through the speakers. If this should
occur, do provide an adequate distance between the cables.
Be very careful during the assembly and disassembly of the rubber string grille, if present. Check that the first metal string holder is properly
inserted before tightening the strings to secure the second one.
The speaker cable terminals accept banana plugs. Remove the red and black plastic caps only if you intend to implement this type of
connection and ensure that the other end of the cable is connected to the power output terminals of your amplifier. This protection is aimed
at avoiding accidental connection to unprotected electrical outlets.
