RECOMMENDATIONS FOR CHOOSING THE AUDIO AMPLIFIER
The output power data required by amplifier in average conditions of use, depends on the features
of the loudspeaker system (nominal impedance and sensitivity) and listening conditions (average
acoustic level and listening point). In the case of loudspeaker with nominal impedance of 4 ohm and
sensitivity of 92 dBSPL, the following table is given
Audio programs with higher peak factors require even higher amplification powers.
As it can be seen, the cost in terms of amplification is not so much the maintenance of the listening
level as the management of the very short moments in which the musical signal has extraordina

rily high levels.

1.2 WARRANTY AND AFTER SALES SUPPORT
Palladio Level 6 loudspeakers are designed and manufactured according to the highest quality
standards.
Should, however, a fault or a malfunction occur, the loudspeakers are covered by warranty, in
compliance with the regulations in force in the country where the loudspeakers were purchased.
In such cases, please contact the dealer from whom you purchased your loudspeakers, or the official
Sonus faber distributor for your country; the contact information for all the distributors can be found
on our website:
•
https://www.sonusfaber.com/distributori-store/
•
https://www.sonusfaber.com/en/distributors-stores/
The following should also be kept in mind for your convenience:
•
The warranty on the loudspeakers covers any manufacturing defects;
•
Keep the receipt as proof of purchase to show to the retailer if necessary;
•
Keep the original packaging of the loudspeakers so that they can be transported or shipped to
an authorised service centre without undergoing damage;
•
The loudspeakers must be accompanied by a description of the malfunction or defect
encountered.
The product warranty will be void under the following conditions:
•
If the product has been disassembled or modified by persons other than a Sonus faber
authorised service centre;
•
If the product has been used in a manner that is not consistent with the indications contained
within this manual.
2. SAFETY INFORMATION
•
This instruction manual must be read carefully and kept in an accessible location for any needs
that may arise.
•
Make sure that in-wall/in-ceiling fixing is suitably stable.
•
Previously check that the capacity of the mounting surface is sufficient to support the weight
of the loudspeaker/s.
•
Avoid staying in close proximity to the loudspeakers while the audio system is operating at
high volume. This can cause permanent damage to your hearing. Children must be kept at a
safety distance of least 50 cm from the loudspeaker.
•
The speakers generate an electromagnetic field that is harmless to humans and pets, but
can compromise the proper functionality of electronic equipment, such as CRT monitors or
TVs, when placed in close proximity. If this occurs, increase the equipment’s distance from the
loudspeakers.
•
The technology underlying the speakers’ functionality is based on the principles of
electromagnetism, and the user should therefore avoid operating equipment that generates
strong electromagnetic fields, as these could affect the loudspeaker’s proper functionality.
•
Do not connect the loudspeakers parallel to each other or directly to a constant voltage sound
distribution system (100 V, 70.7 V or similar). This could result in a serious system overload,
with possible damage to the loudspeaker and/or the amplifier.
•
Do not place audio cables and electrical power cables in close proximity to one another.
An electromagnetic field is present in the vicinity of the power cables, which can cause an
unpleasant humming noise. If this should occur, move the audio cables and electrical power
cables away from each other.
•
The connections must be made with the equipment turned off. Pay attention to the polarities
of the terminals during connection
The packaging materials can cause pollution.
These materials must not be disposed of as domestic waste, and must be brought to
a waste collection and recycling centre.
Do not leave the packaging materials within the reach of children!
They could pose a risk of poisoning or suffocation if ingested.

In this type of application, the powers in question are incompatible with correct
operation of the loudspeaker system and can lead to irreversible faults and, in some
cases, the start of a fire
