About Rotel
A family whose passionate interest in music led them to manufac-
ture high fidelity components of uncompromising quality founded
Rotel over 30 years ago. Through the years that passion has re-
mained undiminished and the family goal of providing exceptional
value for audiophiles and music lovers, regardless of their budget,
is shared by all Rotel employees.
The engineers work as a close team, listening to, and fine tuning
each new product until it reaches their exacting musical stan-
dards. They are 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 Kingdom and Germany,
semi conductors from Japan or the United States, while toroidal
power transformers are manufactured in Rotel’s own factory.
Rotel’s reputation for excellence has been earned through hun-
dreds of good reviews and awards from the most respected re-
viewers in the industry, who listen to music every day. Their
comments keep the company true to its goal – the pursuit of
equipment that is musical, reliable and affordable.
All of us at Rotel thank you for buying this product and hope it will
bring you many hours of enjoyment.

About the THX
®
System
The THX system was developed by the THX Division of Lucasfilms,
Ltd. to ensure the finest reproduction of surround sound movies.
With a THX system, the surround sound encoded movies you
watch are reproduced in a realistic recreation of the way they
were mixed on the sound stage. This faithful recreation of the
movies will allow you to experience the excitement and the enter-
tainment intended by the directors of your favorite films. Rotel has
designed the RB-985 MKII to meet the THX Division performance
specifications so that you have an accurate recreation of the
movie soundtrack in your living room or home theater system. This
ensures that our equipment is compatible with other Rotel THX
products or with THX products from other companies.
The THX standard yields the best home theater sound because
the certification process requires tight adherance to the system
performance standards. Rotel components are famous for high
performance and high value. We feel the THX certification is a
logical extension of our efforts to provide the best possible audio
reproduction of surround sound movies.
