8A10MKII Stereo Integrated Amplifier
Getting Started
Thank you for purchasing the Rotel A10MKII Stereo Integrated Amplier.
When used in a high-quality music audio system, it will provide years of
musical enjoyment.
The amplier 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 unit 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 unit 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 circuitry uses metal lm 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 A10MKII are easy to install and use. If you
have experience with other stereo systems, you shouldn’t nd 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 unit 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 unit shipping carton and all enclosed packing material for future
use. Shipping or moving the unit in anything other than the original
packing material may result in severe damage to your amplier.
If included in the box please complete the owner’s registration card or
register online. 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 amplier
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 amplier 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 amplier from overheating.
Remember the weight of the amplier 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.
The A10MKII is supplied with an RR-AX1402 remote control and must be
placed where the infrared signal from the remote can reach the front
panel Remote Sensor.
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‑AX1403 Remote
Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX1403 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.
Remote Control Batteries
Two AAA size batteries (supplied) must be installed before the remote
control can be used. To install the batteries, remove the cover on the back
of the RR-AX1403. Install the batteries as shown in the illustration in the
battery well. Test the control for proper operation, then replace the cover.
When the batteries become weak the remote control won’t operate the
A10MKII consistently. Installing fresh batteries should eliminate the problem.
Buttons
The remote control can be used to operate the basic functions of Rotel
tuners and CD players. Remote control buttons labeled CEFGHI can
be used to operate CD or Tuner functions in your system. To activate CD
and Tuner controls simply press the CD or TUNER source buttons on the
remote control. Pressing any other source button on the remote control
deactivates these functions.

English
AC Power and Control
AC Power Input t
Your unit is congured 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 conguration
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, it should be plugged directly into a polarized wall outlet using
the supplied cable or other compatible cable as recommended by your
authorized Rotel dealer. 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 unit 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
amplier (as well as other audio and video components) while you are away.
Power Switch 1Aand Power Indicator 2
Press the front panel Power Switch button, to turn the unit on. The Power
Indicator light is illuminated when the unit is on. Press Power Switch
button again to turn the unit off.
When the power switch is in the ON position, the remote control ON and
OFF buttons Amay be used to activate the A10MKII. In Standby mode
the Indicator light is red.
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 unit.
12V Trigger Out =
Some audio components can be turned on automatically when they
receive a 12V turn on “signal”. The two 12V Trigger Outputs of the
amplier provide the required signal. Connect compatible components
to the amplier with a conventional 3.5mm mini plug cable. When the
unit is turned off, the trigger signal is interrupted, and the components
controlled by it are turned off.
Input Signal Connections
See Figure 2
NOTE: To prevent loud noises that neither you nor your speakers
will appreciate, make sure the system is turned off when you make
any signal connections.
Phono Input wand Ground Connection q
Plug the cable from the turntable into the appropriate left and right
phono inputs. If the turntable has a “ground” wire, connect it to the screw
terminal to the left of the Phono inputs. It will help prevent hum and noise.
Line Level Inputs e
The CD, Tuner, and Aux inputs of the amplier are “line level” inputs.
These are for connecting components such as CD players or other audio
playback devices with an analog audio output.
The Left and Right channels are labeled and should be connected to the
corresponding channels of the source component. The Left connectors
are white, the Right connectors are red. Use high quality RCA cables for
connecting input source components to the unit. Ask your authorized
Rotel dealer for advice about cables.
Speaker Outputs r
See Figure 3
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the unit to the
speakers. The size and quality of the wire can have an audible effect on
the performance of the system. Standard speaker wire will work, but
can result in lower output or diminished bass response, particularly
over longer distances. In general, heavier wire will improve the sound.
For best performance, you may want to consider special high-quality
speaker cables. Your authorized Rotel dealer can help in the selection of
cables for your system.
Polarity and Phasing
The polarity – the positive/negative orientation of the connections – for
every speaker and amplier connection must be consistent so all the
speakers will be in phase. If the polarity of one connection is reversed,
bass output will be very weak and stereo imaging degraded. All wire is
marked so you can identify the two conductors. There may be ribs or
a stripe on the insulation of one conductor. The wire may have clear
insulation with different color conductors (copper and silver). There may
be polarity indications printed on the insulation. Identify the positive and
negative conductors and be consistent with every speaker and amplier
connection.

10 A10MKII Stereo Integrated Amplifier
Speaker Connection
NOTE: The following text describes both binding post and plug-in
connections. DO NOT use both connection methods in combination
to connect multiple speakers.
Turn off all the components in the system before connecting the speakers.
The unit has color-coded binding post type speaker connectors on the
back panel (except in European Community countries where their use
is not permitted). These connectors accept bare wire, connector lugs, or
dual banana type connectors.
Route the wire from the unit to the speakers. Give yourself enough slack so
you can move the components to allow access to the speaker connectors.
If you are using dual banana plugs, connect them to the wires and then
plug into the backs of the binding posts. The thumbscrews of the binding
posts should be screwed in all the way (clockwise).
If you are using terminal lugs, connect them to the wires. If you are
attaching bare wires directly to the binding posts, separate the wire
conductors and strip the insulation from the end of each conductor. Be
careful not to cut into the wire strands. Unscrew (turn counterclockwise)
the binding post thumbscrews. Place the connector lug or wire around
the binding post shaft. Turn the thumbscrews clockwise to clamp the
connector lug or wire rmly in place.
NOTE: Be sure there are no loose wire strands that could touch
adjacent wires or connectors.
IR Remote Sensor 4
This remote sensor window receives IR commands from the remote
control. Please do not block this sensor.
Headphone Output 3
The headphone output allows you to connect headphones for private
listening. This output accepts a standard 3.5 mm (1/8”) mini stereo
headphone connector. Plugging in a set of headphones does not cut
off the signal to the outputs.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.
Power Control 0
When the slider is set to the ON position, the A10MKII will be congured
to automatically power off to standby mode if there is no audio signal
for 20 minutes. The auto power off timer will be restarted if changes are
made to the volume, source or playback.
To disable above function, push the slider to the OFF position.
SERVICE Connector -
The SERVICE connector is for use by Authorized Service Centers only.
Audio Controls
Volume Control 8C
Turn the controls clockwise to increase the volume, or counter clockwise
to decrease the volume. From the remote control press the volume +
or - button Cto turn the volume up or down. Press the button Dto
completely mute the volume.
Balance Control 5
The Balance Control adjusts the left-to-right balance of the sound
output. Normally the control should be left in the center position. In
some situations, typically when the main listening position is not ideally
centered between the speakers, it may be necessary to adjust the control
to achieve proper left-to-right balance. Turning the Balance rotary knob
5counter-clockwise shifts the sound balance to the left. Turning the
Balance rotary knob 5clockwise shifts the sound balance to the right.
Bass and Treble Controls 67
Turn the Bass / Treble rotary knobs 67 clockwise to increase the bass or
treble output. Turn the Bass / Treble rotary knobs 67 counterclockwise
to decrease the bass or treble output.
A properly setup high-performance audio system produces the most
natural sound with little or no adjustment of the tone controls. Use these
controls sparingly. Be particularly careful when turning the controls up
(clockwise). This increases the power output in the bass or treble range,
increasing the load on the amplier and speakers.
NOTE: The Bass and Treble controls circuits are bypassed to ensure
the purest possible sound, which is defaulted. Turn the Bass / Treble
rotary knob if you want to adjust the Controls.
Source Input Selector 9G
Press the corresponding input button on the front panel 9or remote
control Gto select the desired listening source.
LED Dimmer Control B
To change the brightness of the Power indicator above the Power button,
the LEDs above the Source selectors and the Volume rotary knob LED on
the front panel, press the DIM Bbutton on the remote control.
Protection Circuit
The unit has both thermal and over-current protection circuitry that
protects the amplier against damage in the event of extreme or faulty
operating conditions. The protection circuits are independent of the audio
signal and have no impact on sonic performance. Instead, the protection
circuits monitor the temperature of the output devices and shut down
the amplier if temperatures exceed safe limits.

11
English
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplier will stop playing and the
POWER indicator 22on the front panel will turn red.
If this happens, turn the amplier off. Let it cool down for several minutes,
and attempt to identify and correct the problem that caused the protection
circuitry to engage. When you turn the amplier back on, the protection
circuit will automatically reset and the POWER indicator 22should be
blue, indicating that the amplier is operating normally.
In most cases, the protection circuitry activates because of a fault condition
such as shorted speaker wires, or inadequate ventilation leading to an
overheating condition. In very rare cases, highly reactive or extremely low
impedance speaker loads could cause the protection circuit to engage.
If the protection circuitry triggers repeatedly and you are unable to isolate
and correct the faulty condition, contact your authorized Rotel dealer for
assistance in troubleshooting.
Troubleshooting
Most difculties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difculty, check the control settings, determine the cause of the
fault and make the necessary changes. If you are unable to get sound
from the unit, refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
The Power Indicator should be illuminated whenever the unit is plugged
into the wall power outlet and the Power button is pushed in. If it does
not light, test the power outlet with another electrical device, such as a
lamp. Be sure the power outlet being used is not controlled by a switch
that has been turned off.
Fuse Replacement
If another electrical device works when plugged into the power outlet,
but the Power Indicator of the unit does not light when plugged into
the same outlet and the Power Switch is pushed in, it indicates that the
internal power fuse may have blown. If you believe this has happened,
contact your authorized Rotel dealer to get the fuse replaced.
No Sound
Check the signal source to see if it is functioning properly. Make sure the
cables from the signal source to the unit inputs are connected properly.
Be sure the Listening Selector is set to the proper input. Check the wiring
between the unit and the speakers..
