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.
