Thank you for purchasing the Rotel RB-03 Ste-
8
reo Power Amplifier. When used in a high-
quality music audio system, it will provide years
of musical enjoyment.
The RB-03 is a full featured, high performance
component. All aspects of the design have been
optimized to retain the full dynamic range and
subtle nuances of your music. The RB-03 has
a highly regulated power supply incorporat-
ing a Rotel custom-designed toroidal power
transformer. This low impedance power sup-
ply has ample power reserves, which enables
the RB-03 to easily reproduce the most de-
manding audio signals. This type of design
is more expensive to manufacture, but it is better
for the music.
The printed circuit boards (PCB) are designed
with Symmetrical Circuit Traces. This insures
that the precise timing of the music is main-
tained and faithfully recreated. The RB-03 cir-
cuitry uses metal film resistors and polystyrene
or polypropylene capacitors in important signal
paths. All aspects of this design have been ex-
amined to ensure the most faithful music re-
production.
The main functions of the RB-03 are easy to
install and use. If you have experience with
other stereo systems, you shouldn't find any-
thing perplexing. Simply plug in the associ-
ated components and enjoy.
A Few Precautions
WARNING: To avoid potential damage to
your system, turn off ALL the components in
the system when connecting or disconnect-
ing the loudspeakers or any associated
components. Do not turn the system compo-
nents back on until you are sure all the con-
nections are correct and secure. Pay
particular attention to the speaker wires.
There must be no loose strands that could
contact the other speaker wires, or the
chassis of the amplifier.
Please read this manual carefully. It provides
information on how to incorporate the RB-03
into your system as well as information that
will help you get optimum sound performance.
Please contact your authorized Rotel dealer
for answers to any questions you might have.
In addition, all of us at Rotel welcome your
questions and comments.
Save the RB-03 shipping carton and all en-
closed packing material for future use. Ship-
ping or moving the RB-03 in anything other
than the original packing material may result
in severe damage to your amplifier.
Fill out and send in the owner's registration
card packed with the RB-03. Also 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.
