A family whose passionate interest in music led them to manufacture high fidelity components of uncompromising quality founded Rotel 40 years ago. Through the years that passion has remained undiminished and the family goal of providing exceptional value for audiophiles and music lovers, regardless of their budget, is shared by all Rotel employees.

The engineers work as a close team, listen- ing to, and fine tuning each new product until it reaches their exacting musical standards. They are free to choose components from around the world in order to make that product the best they can. You are likely to find ca- pacitors from the United Kingdom and Ger- many, semi conductors from Japan or the United States, while toroidal power transform- ers are manufactured in Rotel’s own factory.

Rotel’s reputation for excellence has been earned through hundreds of good reviews and awards from the most respected reviewers in the industry, who listen to music every day. Their comments keep the company true to its goal – the pursuit of equipment that is musi- cal, reliable and affordable.

All of us at Rotel thank you for buying this product and hope it will bring you many hours of enjoyment.

Thank you for purchasing the Rotel RA-972 Stereo Integrated Amplifier. When used in a high-quality music audio system, it will pro- vide years of musical enjoyment.

The RA-972 is a full featured, high perfor- mance component. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The RA-972 has a highly regulated power sup- ply incorporating a Rotel custom-designed to- roidal power transformer and custom-made slit foil capacitors. This low impedance power supply has ample power reserves, which enables the RA-972 to easily reproduce the most demanding 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 main- tained and faithfully recreated. The RA-972 circuitry uses metal film resistors and poly- styrene or polypropylene capacitors in impor- tant signal paths. All aspects of this design have been examined to ensure the most faithful music reproduction.

In addition the RA-972 has independent in- put signal selectors for listening and record- ing. They allow you to listen to one signal source while recording another.

The main functions of the RA-972 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 associ- ated components and enjoy.
