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.
