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 shipping carton and all enclosed packing material for future use.
Shipping or moving the amplier in anything other than the original packing
material may result in severe damage to your amplier.
If included in the box please ll 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 amplier
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 amplier 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 airow through
the installation location, to prevent the amplier from overheating.
Remember the weight of the amplier 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 analog audio
signal cables in your installation away from each other. This will minimize
the chance of the analog 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-AX1401 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX1401 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 Amplier Remote Code
The factory setting is remote code 1. If you nd that the remote is conicting
with other Rotel ampliers, you can change to remote code 2 with the
following steps.
1. From the remote control press Tuner Iand 2 Mat the same time for 5
seconds, to set the remote control to send Audio Code 2.
2. Point the remote at the unit and press 2 Mbutton for 14 seconds. The
unit will show “Audio Code SET 1 -> 2”.
3. Repeat the above procedure and press “1” button 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 GHMN
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.
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-AX1401. 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 A11 consistently.
Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input o
Your unit is congured 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 conguration 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 amplier 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
amplier (as well as other audio and video components) while you are away.

10 A11 Stereo Integrated Amplier
Power Switch 1Aand Power Indicator 2
Press the front panel Power Switch button 1to turn the unit on. The Power
Indicator light 2is 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 may be used to activate the A11. In Standby mode the power
LED is red, but the display is turned OFF.
12V Trigger Connection e
See Figure 4
Some audio components can be turned on automatically when they receive
a 12V turn on signal. The two 12V Trigger Outputs of the A11 unit provide
the required signal. Connect compatible components to the amplier with a
conventional 3.5mm mini plug cable. When the unit is in standby mode or
turned off, the trigger signal is interrupted, and the components controlled
by it are turned off.
Protection Indicator 2
The amplier has both thermal and over-current protection circuitry that
protects the amplier 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
amplier if temperatures exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplier will stop playing and will
display “AMP PROTECTION“ on the front panel. The power indicator 2
on the front panel will turn red.
If this happens, turn the amplier 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 amplier back on, the protection
circuit will automatically reset and the power indicator 2should turn blue.
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.
Input Signal Connections
See Figure 3
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 0and Ground Connection (GND) 9
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 -=t
The CD, Tuner, and Aux inputs of the amplier 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.
Preamp Output y
The amplier has a set of preamp outputs labeled PRE OUT. The currently
selected source input is available from this output. Typically the PRE OUT
output is used to provide a signal to another integrated amplier or power
amplier, which is used to drive remote speakers.
NOTE: Changes to the settings of the Volume, Balance or Tone controls
affect the signal from the Preamp Output.
Speaker Outputsui
See Figure 3
Speaker Selector Switch 4
The amplier has two sets of speaker outputs, labeled “SPEAKER A” uand
“SPEAKER B” i. The speaker outputs are controlled by the A-B speaker
selector buttons 4on the front panel or Jon the remote control.
Speaker Selection
If only one set of speakers will be used at any given time, the speakers may
have an impedance as low as 4 ohms. If there are times when both the A
and B speakers will be used, all the speakers should have an impedance
of 8 ohms or more. Speaker impedance ratings are less than precise. In
practice, very few loudspeakers will present any problems for the unit. See
your authorized Rotel dealer if you have any questions.
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 amplier 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 amplier connection.

11
Speaker Connection
Turn off all the components in the system before connecting the speakers.
The amplier has color-coded binding post type speaker connectors on the
back panel. These connectors accept bare wire, connector lugs, or dual
banana type connectors. (Except in European Community countries where
their use is not permitted.)
Route the wire from the amplier 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.
Headphone Output 3
The headphone output allows you to connect headphones for private listening.
This output accepts a standard 3.5mm (1/8”) mini stereo headphone
connector. Plugging in a set of headphones does not cut off the signal to the
speakers. Use the front panel 4or remote control JA-B speaker selector
buttons to turn off the speakers.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.
Display 5
The front panel display shows the source selected, volume level and tone
settings. The display provides access to the setup and conguration menu
options of the amplier.
APTX Bluetooth Connection q
The Bluetooth Antenna qon the unit’s back panel is for wireless streaming
via Bluetooth, from your device (i.e. mobile phones, tablets or computers).
From your device, look for “Rotel Bluetooth” and connect to it. Connection
is normally automatic, but if prompted for a password, please enter “0000”
on your device. The unit supports both traditional Bluetooth and APTX
Bluetooth audio streaming.

Troubleshooting
Most difculties in audio systems are the result of incorrect connections, or
improper control settings. If you encounter problems, isolate the area of the
difculty, 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 and the basic items in the Display window should be
illuminated whenever the unit is plugged into the wall power outlet and the
Power button is pushed in. If it does not illuminated, 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 still will not illuminated when the unit is plugged into
the wall outlet, 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 amplier inputs are connected properly.
Be sure the Input Source is set to the proper input. Check the wiring between
the amplier and the speakers.
Playable Audio Formats
APTX Bluetooth
Format Notes
Any format supported
by the sending device.
May exclude Apps designed to play formats not originally
supported by the sending device.
Cannot Connect via Bluetooth
If you cannot pair your Bluetooth enabled device to the A11, delete the
memory of the previous connection on your device. On your device this is
often listed as “Forget this Device”. Then try to make the connection again.
