PRECAUTIONS
The AT5XX
NC
amplifier is a wide-band design with substantial power output capability. Certain precau-
tions must be taken to ensure proper operation.
•
Never expose the amplifier to moisture.
•
Never plug an input cable into the amplifier while the unit is turned on.
•
Never apply the “thumb test” (touching the “hot” lead of the input cable with your finger) to the tip of
the input cable or input jack of the ATI amplifier. RF rectification and/or hum will be created and could
cause damage to the loudspeakers. ATI will not be responsible for damage to the loudspeakers due
to improper use of the equipment.
•
Under no circumstances should the output terminals of the AT5XX
NC
be short-circuited.
•
Avoid restricting the airflow around the AT5XX
NC
amplifier. Good airflow is necessary to ensure prop-
er cooling and trouble-free operation.
•
Ensure that the rated power handling of the loudspeakers connected to the AT5XX
NC
amplifier can
handle the output power of the amplifier. The warranty of the
AT5XX
NC
does not cover damage to
loudspeakers with inadequate power handling capability.
•
Do not stack other system components or any other materials on top of the AT5XX
NC
amplifier. The
amplifier is convection cooled and air must be free to circulate around its chassis.
