Getting Started
Thank you for purchasing the Rotel RA-04
Stereo Integrated Amplifier. 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 film 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 find any-
thing perplexing. Simply plug in the associated
components and enjoy.
