A Few Precautions; Placement; Cables; The Rr-Ax91 Remote Control - Rotel RA-12 Manual De Instrucciones

The main functions of the RA-12 and RA-11 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.
NOTE: The operations and feature of RA-12 and RA-11 are the same.
The illustrations in the manual use the RA-12 as an example, but all
sockets and buttons are the same on the RA-11.

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-12/RA-11 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 shipping carton and all enclosed packing material for future use.
Shipping or moving the amplifier in anything other than the original packing
material may result in severe damage to your amplifier.
If included in the box please fill out and send in the owner's registration
card. 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, this amplifier
can be affected by its environment. Avoid placing the unit 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 unit 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 unit 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.

The RR-AX91 Remote Control

Some functions can be done with either the front panel controls, or the
supplied RR-AX91 remote control. When these operations are described,
the square call out numbers refer to the main unit, while the encircled letters
refer to the remote control.

Second Amplifier Remote Code

The factory setting is remote code 1. If you find that the remote is conflicting
with other Rotel amplifiers, you can change to remote code 2 with the
following steps.
1. From the remote control press Tuner
the remote control to send Audio Code 2.
2. Point the remote at the unit and press 2
will show "Audio Custom Code 1 -> 2".
3. Repeat the above procedure and press "1" key instead of "2" to change
the unit back to Code 1.
NOTE: The remote control can be used to operate the basic functions
of Rotel tuners and CD players. Remote control keys labeled
can be used to operate CD or Tuner functions in your system. For the
remote to operate properly, make sure both the remote and the CD or
Tuner are both in same remote code, either Code 1 or 2.

AC Power and Control

AC Power Input o
Your unit 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 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 unit
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.
The unit 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 amplifier and all the other components connected to it.
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.
