About Rotel
Our story began over 50 years ago. Over the decades, we have received
hundreds of awards for our products and satisfied hundreds of thousands
3
of people who take their entertainment seriously - like you!
4
5
Rotel was founded by a family whose passionate interest in music led them
6
to manufacture high-fidelity components of uncompromising quality. Through
7
the years, that passion has remained undiminished and the family goal of
8
providing exceptional value for audiophiles and music lovers, regardless
9
of their budget, is shared by all Rotel employees.
10
Rotel's engineers work as a close team, listening to, and fine tuning, each
new product until it reaches their exacting musical standards. They are
12
free to choose components from around the world in order to make that
12
product the best they can. You are likely to find capacitors from the United
12
Kingdom and Germany, semiconductors from Japan or the United States,
12
while toroidal power transformers are manufactured in Rotel's own factory.
12
We all have concerns about our environment. And, as more and more
12
electronics are produced it is especially important for a manufacturer to do all
12
it can to engineer products that have a minimum impact on the environment.
13
At Rotel, we are proud to do our part. We have reduced the lead content
13
in our products by using special lead-free ROHS solder and components.
13
Our engineers continually strive to improve power supply efficiency without
13
compromise to quality. When in standby mode Rotel products use minimal
13
power to meet global Standby Power Consumption requirements.
13
The Rotel factory is also doing their part to help the environment through
13
constant improvements to product assembly methods for a cleaner and
13
greener manufacturing processes.
All of us at Rotel thank you for buying this product. We are sure it will bring
you many years of enjoyment.
Getting Started
Thank you for purchasing the Rotel RC-1572 Stereo Control Amplifier. When
14
used in a high-quality music audio system, your Rotel product will provide
14
years of musical enjoyment.

14
The RC-1572 is a full featured, high performance component. All aspects
14
of the design have been optimized to retain the full dynamic range and
subtle nuances of your music. The RC-1572 has a highly regulated power
15
supply incorporating a Rotel custom-designed toroidal power transformer
15
and custom-made slit foil capacitors. This low impedance power supply has
ample power reserves, which enables the RC-1572 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 ensures that the precise timing of the music is maintained and faithfully
17
recreated. The RC-1572 circuitry uses metal film resistors and polystyrene
17
or polypropylene capacitors in important signal paths. All aspects of this
17
design have been examined to ensure the most faithful music reproduction.
17
17
The main functions of the RC-1572 are easy to install and use. If you have
experience with other stereo systems, you shouldn't find anything perplexing.
Simply plug in the associated components and enjoy.
