Getting Started
Thank you for purchasing the Rotel RB-1080
Stereo Power Amplifier. When used in a high-
quality music or home theater system, your
Rotel amplifier will provide years of musical
enjoyment.
The RB-1080 is a high-power, two-channel
power amplifier, providing the highest level
of audio performance. Discrete output devices,
a massive power supply, premium components,
and Rotel’s Balanced Design ensure superb
sound quality. High current capability allows
the RB-1080 to drive the most demanding loud-
speakers.
Be aware that the RB-1080 is capable of high
power levels, in excess of 200 watts per chan-
nel. Make sure that your speakers can handle
the power of the RB-1080. If in doubt about
your speakers, ask your local Rotel audio
dealer for advice.
The RB-1080 is straightforward in its instal-
lation and operation. If you have experience
with other stereo power amplifiers, you
shouldn’t find anything perplexing. Plug in a
pair of high-quality RCA cables from your
preamp into the amplifier inputs, wire up your
speakers, and enjoy. Alternatively, the RB-1080
provides an optional pair of balanced inputs
for use with preamps or processors that of-
fer these low-noise XLR-connections. If you
choose this option, you will need to reset a
back panel switch selecting the balanced in-
puts. Again, nothing very confusing.
A Few Precautions
Please read this manual carefully. In addition
to basic installation and operating instructions,
it provides valuable information on various
RB-1080 system configurations as well as gen-
eral information that will help you get opti-
mum performance from your system. Please
contact your authorized Rotel audio dealer
for answers to any questions you might have.
In addition, all of us at Rotel welcome your
questions and comments.
Save the RB-1080 shipping carton and all en-
closed packing material for future use. Ship-
ping or moving the RB-1080 in anything other
than the original packing material may re-
sult in severe damage to your amplifier.
Fill out and send in the owner’s registration
card packed with the RB-1080. Also be sure
to keep the original sales receipt. It is your
best record of the date of purchase, which you
will need in the event warranty service is ever
required.
