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 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 find any- thing perplexing. Simply plug in the associated components and enjoy.
