About Rotel
3
A family whose passionate interest in music led
4
them to manufacture high fi delity components
of uncompromising quality founded Rotel over
40 years ago. Through the years that passion
has remained undiminished and the family goal
of providing exceptional value for audiophiles
6
and music lovers regardless of their budget, is
6
shared by all Rotel employees.
6
The engineers work as a close team, listening
6
to, and fi ne tuning each new product until it
reaches their exacting musical standards. They
are free to choose components from around
6
the world in order to make that product the
best they can. You are likely to fi nd capacitors
6
from the United Kingdom and Germany, semi
6
conductors from Japan or the United States,
while toroidal power transformers are manu-
factured in Rotel's own factory.
Rotel's reputation for excellence has been
earned through hundreds of good reviews and
7
awards from the most respected reviewers in
7
the industry, who listen to music every day.
Their comments keep the company true to its

Getting Started
Thank you for purchasing the Rotel RA-04
Stereo Integrated Amplifi er. When used in a
high-quality music audio system, it will provide
years of musical enjoyment.
The RA-04 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 RA-04 has
a highly regulated power supply incorporat-
ing a Rotel custom-designed toroidal power
transformer. This low impedance power supply
has ample power reserves, which enables the
RA -04 to easily reproduce the most demand-
ing 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 maintained
and faithfully recreated. The RA-04 circuitry
uses metal fi lm resistors and polystyrene or
polypropylene capacitors in important signal
paths. All aspects of this design have been
examined to ensure the most faithful music
reproduction.
The main functions of the RA-04 are easy to
install and use. If you have experience with
other stereo systems, you shouldn't fi nd any-
thing perplexing. Simply plug in the associated
components and enjoy.
