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 performance 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 supply 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 design have been examined with the final goal being faithful
reproduction of music.
The RC-972 is straightforward in its installation and operation. If
you have experience with other stereo systems, you shouldn’t find
anything perplexing. Simply plug in the associated components
and enjoy.
