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.

English

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 shouldnt 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.
