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.
