Hints on Installation
This user manual contains important information on operating 2A series amplifier correctly and safety. Please
read it carefully before operating your amplifier.
INSPECTION
Your 2A Series was carefully packed at the factory in packaging designed to protect the units in
shipment. Before installing and using your unit, carefully examine the packaging and all contents for any
signs of physical damage. If you find any damage, notify the shipping company immediately. Be sure to
save the carton and all packing materials for carrier inspection.
RACK MOUNTING
The 2A Series amplifiers are designed for standard 19" rack mounting as well as stand alone. Use 4 screws
and washers for mounting to the front rack rails. It is also a good idea to support the amps in the rear,
especially for mobile use where the amps will be subjected to strong vibrations.
AMPLIFIER COOLING
Also pay close attention to the cooling requirements. Never block the air vents in the back, side and front
of the amplifier. Do not install the amplifier in a location that is exposed to direct rays of the sun or near
the hot appliance or radiators. Installation of the amplifiers in a damp or dust environment may result in
malfunction or accident. Please make sure to open the back doors, if installed in a rack. Periodically
remove the internal dust by using compressed air thought the external ventilation holes.
