Save the RB-1072 shipping carton and packing
material for future use. Shipping or moving the
RB-1072 in anything other than the original
packing material may result in severe damage
to your amplifier.
Be sure to keep the original sales receipt. It is
your best record of the date of purchase, which
you will need in the event warranty service is
ever required.
Placement
The RB-1072 generates heat as part of its
normal operation. The heat sinks and ventila

tion openings in the amplifier are designed to
dissipate this heat. The ventilation slots in the
top cover must be unobstructed. There should
be 10 cm (4 inches) of clearance around the
chassis, and reasonable airflow through the
installation location, to prevent the amplifier
from overheating. Likewise, remember the
weight of the amplifier when you select an
installation location. Make sure that the shelf
or cabinet can support its weight.
