Getting Started
Thank you for purchasing the Rotel RA-03
Stereo Integrated Amplifier. When used in a
high-quality music audio system, it will provide
years of musical enjoyment.
The RA-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 RA-03 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-03 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-03 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-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 associated
components and enjoy.
The RR-AT94 Remote Control
Some functions can be done with either the front
panel controls, or the supplied RR-AT94 remote
control. When these operations are described,
the call out number for both controls is shown.
For example, you can adjust the volume with
either the front panel Volume control
0
or
the remote control buttons
a
.
See the “IR Inputs and Output” section for more
information on ways to expand the IR control
capabilities of your system.
Note:
Remove the batteries from the re-
mote control if it will not be used for a long
period of time. Do not leave run down bat-
teries in the remote control. Exhausted bat-
teries can leak corrosive chemicals which
will damage the unit.
NOTE:
The RR-AT94 can be used to oper-
ate the basic function of other certain other
Rotel components, including Tuners, CD
Players and DVD Players.
