Getting Started
7
7
Thank you for purchasing the Rotel RMB-1048
7
Eight-Channel Power Amplifier. When used
in a high-quality music or home theater sys-
tem, your Rotel amplifier will provide years
8
of musical enjoyment.
8
The RMB-1048 is a sophisticated eight-channel
8
power amplifier. Discrete output devices, a
massive power supply with toroidal trans-
former, premium components, and Rotel's
Balanced Design ensure superb sound qual-
ity. High current capability allows the
RMB-1048 to drive difficult speaker loads with
ease.
Operating Features
• Four pair of amplifier channels.
• User selectable power on/off configura-
tion: manual or controlled by remote 12
volt trigger signal.
• Front panel input level controls.
• Protection circuitry with front panel indi-
cators.
• Signal link output to pass-through the in-
put signal to another component.
A Few Precautions
Please read this manual carefully. In addition
to installation and operating instructions, it
provides information on various RMB-1048
system configurations. Please contact your au-
thorized Rotel dealer for answers to any ques-
tions you might have. In addition, all of us at
Rotel welcome your questions and comments.
Save the RMB-1048 shipping carton and
packing material for future use. Shipping or
moving the RMB-1048 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 RMB-1048 generates heat as part of its
normal operation. The heat sinks and venti-
lation 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.
