Getting Started
Thank you for purchasing the Rotel RC-972
Stereo Control Amplifier. When used in a high-
quality music audio system, it will provide years
of musical enjoyment.
The RC-972 is a full featured, high perfor-
mance preamplifier. All aspects of the design
have been optimized to retain the full dynamic
range and subtle nuances of your music. The
RC-972 has a highly regulated power sup-
ply incorporating a Rotel custom-designed
power transformer. This low impedance power
supply has ample power reserves, which
enables the RC-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 RC-972 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
RC-972 circuitry uses metal film resistors and
polystyrene or polypropylene capacitors in
important signal paths. All aspects of this de-
sign have been examined with the final goal
being faithful reproduction of music.
The RC-972 is straightforward in its installa-
tion and operation. If you have experience
with other stereo systems, you shouldn’t find
anything perplexing. Simply plug in the as-
sociated components and enjoy.
