Getting Started

Thank you for purchasing the Rotel RA-10 Stereo Integrated Amplifier.
When used in a high-quality music audio system, it will provide years
of musical enjoyment.
The RA-10 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 RA-10 has a highly regulated power
supply incorporating a Rotel custom-designed toroidal power transformer.
This low impedance power supply has ample power reserves, which
enables the RA-10 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 RA-10 circuitry uses metal film 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.
The main functions of the RA-10 are easy to install and use. If you
have experience with other stereo systems, you shouldn't find anything
perplexing. Simply plug in the associated components and enjoy.

A Few Precautions

WARNING: To avoid potential damage to your system, turn off ALL
the components in the system when connecting or disconnecting the
loudspeakers or any associated components. Do not turn the system
components back on until you are sure all the connections are correct
and secure. Pay particular attention to the speaker wires. There must
be no loose strands that could contact the other speaker wires, or the
chassis of the amplifier.
Please read this manual carefully. It provides information on how to
incorporate the RA-10 into your system as well as information that will
help you get optimum sound performance. Please contact your authorized
Rotel dealer for answers to any questions you might have. In addition,
all of us at Rotel welcome your questions and comments.
Save the RA-10 shipping carton and all enclosed packing material for
future use. Shipping or moving the RA-10 in anything other than the original
packing material may result in severe damage to your amplifier.
Fill out and send in the owner's registration card packed with the RA-10.
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.

Placement

Like all audio components that handle low level signals, the RA-10 can
be affected by its environment. Avoid placing the RA-10 on top of other
components. Also avoid routing audio signal cables near power cords.
This will minimize the chance it will pick up hum or interference.
The RA-10 generates heat as part of its normal operation. The heat sinks
and ventilation openings in the amplifier are designed to dissipate this
heat. The ventilation slots in the top cover must be open. There should
be 10 cm (4 inches) of clearance around the chassis, and reasonable

airflow through the installation location, to prevent the amplifier from
overheating.
Remember the weight of the amplifier when you select an installation
location. Make sure that the shelf or cabinet can support it. We recommend
installing the RA-10 in furniture designed to house audio components. Such
furniture is designed to reduce or suppress vibration which can adversely
affect sound quality. Ask your authorized Rotel dealer for advice about
component furniture and proper installation of audio components.

Cables

Be sure to keep the power cords, digital signal cables and regular
audio signal cables in your installation away from each other. This will
minimize the chance of the regular audio signal cables picking up noise
or interference from the power cords or digital cables. Using only high
quality, shielded cables will also help to prevent noise or interference from
degrading the sound quality of your system. If you have any questions
see your authorized Rotel dealer for advice about the best cable to use
with your system.
AC Power and Control

AC Power Input

o
The RA-10 does not draw high levels of current from the power outlet.
However, whenever possible, it should be plugged directly into a 2-pin
polarized wall outlet. Do not use an extension cord. A heavy duty
multi-tap power outlet strip may be used if it (and the wall outlet) can
handle the current demanded by the RA-10 and all the other components
connected to it.
Your RA-10 is configured at the factory for the proper AC line voltage in
the country where you purchased it (either 120 volts AC or 230 volts AC
with a line frequency of either 50 Hz or 60 Hz). The AC line configuration
is noted on a decal on the back panel.
NOTE: Should you move your RA-10 amplifier to another country, it is
possible to reconfigure it for use on a different line voltage. Do not attempt
to perform this conversion yourself. Opening the enclosure of the RA-10
exposes you to dangerous voltages. Consult a qualified service person
or the Rotel factory service department for information.
NOTE: Some products are intended for sale in more than one country
and as such are supplied with more than one AC cord. Please only use
the one appropriate for your country/region.
If you are going to be away from home for an extended period of time
such as a month-long vacation, it is a sensible precaution to unplug your
amplifier (as well as other audio and video components) while you are
away.
Power Switch and Power Indicator

Press the front panel Power Switch button, to turn the RA-10 on. The Power
Indicator light is illuminated when the RA-10 is on. Press Power Switch
button again to turn the RA-10 off.
See the "12V Trigger Outlet" section for more information on ways you
may be able to turn on and off other components in your system along
with the RA-10.
