About Rotel
Our story began over 50 years ago. Over the decades, we have received
3
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
5
to manufacture high-fidelity 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
7
of their budget, is shared by all Rotel employees.
7
7
RotelÊs engineers work as a close team, listening to, and fine tuning, each
new product until it reaches their exacting musical standards. They are
7
free to choose components from around the world in order to make that
product the best they can. You are likely to find capacitors from the United
7
Kingdom and Germany, semiconductors from Japan or the United States,
8
while toroidal power transformers are manufactured in RotelÊs own factory.
8
We all have concerns about our environment. And, as more and more
8
electronics are produced and later discarded, it is especially important for
8
a manufacturer to do all it can to engineer products that have a minimum
8
negative impact on landfill sites and water tables.
8
At Rotel, we are proud to do our part. We have reduced the lead content
in our electronics by using special ROHS solder, while our new Class D
8
(not digital) amplifiers are up to five times more efficient than our legacy
9
designs and still deliver power and performance. These products run cool,
give minimum wasted energy, are good for the environment and give better
9
sound too.
9
Finally, we have printed this manual on recycled paper stock.
9
While we understand that these are small first steps, they are still important
9
ones. And we continue to pursue new methods and materials for a cleaner
9
and greener manufacturing process.

All of us at Rotel thank you for buying this product. We are sure it will bring
10
you many years of enjoyment.

Getting Started
10
Thank you for purchasing the Rotel RC-1580MKII Stereo Control Amplifier.
10
When used in a high-quality music audio system, your Rotel product will
10
provide years of musical enjoyment.
10
The RC-1580MKII 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-1580MKII 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-1580MKII 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 maintained and
faithfully recreated. The RC-1580MKII circuitry uses metal film resistors
and polystyrene or polypropylene capacitors in important signal paths.
