Technical and Safety Notices
Please read the following important technical, safety and
environmental notices before installing and using your amplifier.
Technical Notices
All reasonable design and engineering steps have been taken to ensure that
these amplifiers always perform satisfactorily in their intended application
and environment and will provide appropriate levels of support to ensure
that all reasonable customer needs and expectations are met. Such support
however is contingent on the following provisions.
1. These amplifiers are Class-I products and should be installed with a mains
cable including the required earth connection to comply with the Safety
Class-I.
2. These amplifiers should always be installed by competent and qualified
personnel. Amplifier damage or failure caused by installation or operational
errors may invalidate support, warranty or guarantees of performance.
3. These amplifiers are not suitable for use in locations where they may be
accessible to minors.
4. These amplifiers are intended to be used specifically for the amplification
of audio signals and for connection to moving-coil loudspeaker systems. Use
of these amplifiers for amplification of signals outside the audio band (20Hz
to 20kHz) or to drive transducers other than moving-coil loudspeakers may
invalidate support, warranty or guarantees of performance.
5. These amplifiers should only be used within professionally installed and
configured audio systems comprising input and output ancillary equipments
that is known to be of an appropriate level of performance and in good
operating condition. Any damage to, or unsatisfactory performance from,
these amplifiers caused by inadequate or failed input or output ancillaries
may invalidate support, warranty or guarantees of performance.
6. These amplifiers are intended to be installed and operated indoor
in a controlled environment (pollution degree, PD2) within an ambient
temperature range of 0°C to 40°C. These amplifiers are not intended for
use above 2000 meters above sea level. Amplifiers installed or operated
in environments outside these limits may invalidate support, warranty or
guarantees of performance.
7. Specific warranty terms are the responsibility of the amplifier re-seller.
Safety and Environmental Notices
Note: The intent of the lightning flash with arrowhead symbol in a triangle is
to alert the user to the presence of uninsulated “dangerous” voltage within the
product’s enclosure that may be of sufficient magnitude to constitute a risk of
electric shock to humans.
Note: The intent of the exclamation point within an equilateral triangle is
to alert the user to the presence of important safety, and operating and
maintenance instructions in this manual.
WARNING! TO PREVENT FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS EQUIPMENT
TO RAIN OR MOISTURE.
Ambient Temperature Note: If this equipment is
operated in a confined or multiple rack installation,
the internal ambient operating temperature may
exceed the external ambient temperature. It is
important to ensure in these circumstances that the
published maximum operating temperature for the
equipment is not exceeded.
Reduced Air Flow: Ensure that rack or other closed installation does
not restrict the cooling airflow required for safe and reliable operation
of the equipment.
