About Rotel
Our story began nearly 50 years ago. Over the decades, we have
received hundreds of awards for our products and satisfied hundreds
3
of thousands of people who take their entertainment seriously - like
3
you!

Rotel was founded by a family whose passionate interest in music
led them to manufacture high-fidelity components of uncompromising
quality. Through the years, that passion has remained undiminished
7
and the family goal of providing exceptional value for audiophiles
7
and music lovers, regardless of their budget, is shared by all Rotel
7
employees.
7
Rotel's engineers work as a close team, listening to, and fine tuning,
7
each new product until it reaches their exacting musical standards.
They are free to choose components from around the world in order to
7
8
make that product the best they can. You are likely to find capacitors
from the United Kingdom and Germany, semiconductors from Japan or
the United States, while toroidal power transformers are manufactured
8
in Rotel's own factory.

We all have concerns about our environment. And, as more and more
electronics are produced and later discarded, it is especially important
for a manufacturer to do all it can to engineer products that have a
8
minimum 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 (not digital) amplifiers are up to five times more efficient than
our legacy designs and still deliver power and performance. These
9
products run cool, give minimum wasted energy, are good for the
9
environment and give better sound too.

Finally, we have printed this brochure on recycled paper stock.

While we understand that these are small first steps, they are still
10
important ones. And we continue to pursue new methods and
materials for a cleaner and greener manufacturing process.

Thank you for purchasing the Rotel RC-1550 Stereo Control Amplifier.
10
When used in a high-quality music audio system, it will provide years
of musical enjoyment.
The RC-1550 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-1550 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-1550 to easily reproduce the most demanding audio signals.
This type of design is more expensive to manufacture, but it is better
for the music.
