They are free to choose components from

around the world in order to make that product

Getting Started

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.
