About Rotel
Our story began over 60 years ago. Over the decades, we have received
hundreds of awards for our products and satised hundreds of thousands
of people who take their entertainment seriously - like you!
Rotel was founded by a family whose passionate interest in music led them
t
o manufacture high-delity components of uncompromising quality. Through
the years, that passion has remained undiminished and the family goal of
providing exceptional value for audiophiles and music lovers, regardless
of their budget, is shared by all Rotel employees.
Rotel’s engineers work as a close team, listening to, and ne tuning, each
new product until it reaches their exacting musical standards. They are
free to choose components from around the world in order to make that
product the best they can. You are likely to nd capacitors from the United
Kingdom and Germany, semiconductors from Japan or the United States,
while toroidal power transformers are manufactured in Rotel’s own factory.
We all have concerns about our environment. And, as more and more
electronics are produced it is especially important for a manufacturer to do all
it can to engineer products that have a minimum impact on the environment.
At Rotel, we are proud to do our part. We have reduced the lead content
in our products by using special lead-free ROHS solder and components.
Our engineers continually strive to improve power supply efciency without
compromise to quality. When in standby mode Rotel products use minimal
power to meet global Standby Power Consumption requirements.
The Rotel factory is also doing their part to help the environment through
constant improvements to product assembly methods for a cleaner and
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-1572MKII Stereo Control Amplier.
When used in a high-quality music audio system, your Rotel product will
provide years of musical enjoyment.
The RC-1572MKII is a full featured, high performance component. All aspects
of the design have been optimized to retain the full dynamic range and subtle
nuances of your music. The RC-1572MKII has a highly regulated power
supply incorporating a Rotel custom-designed toroidal power transformer
and custom-made slit foil capacitors. This low impedance power supply has
ample power reserves, which enables the RC-1572MKII 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 recreated. The RC-1572MKII circuitry uses metal lm resistors
and polystyrene or polypropylene capacitors in important signal paths.
All aspects of this design have been examined to ensure the most faithful
music reproduction.
