Getting Started
Thank you for purchasing the Rotel A14 Stereo Integrated Amplifier. When
used in a high-quality music audio system, Rotel products will provide years
of musical enjoyment.
This amplifier 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
amplifier 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 ensures that the precise timing of the music is maintained and
faithfully recreated. The 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 A14 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 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 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 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-AX1400 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX1400 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 Amplier 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 Iand 2 Mat the same time to set
the remote control to send Audio Code 2.
2. Point the remote at the unit and press 2 Mbutton for 8 seconds. The
unit 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 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‑AX1400. 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 A14 consistently.
Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input s
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.

12 A14 Stereo Integrated Amplifier
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 1Aand Power Indicator 2
Press the front panel Power Switch button 1, to 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 A14. In Standby mode the power
LED is red, but the display is turned OFF.
12V Trigger Connection u
See Figure 5
Some audio components can be turned on automatically when they receive
a 12V turn on signal. The two 12V Trigger Outputs of the A14 unit provide
the required signal. Connect compatible components to the amplifier 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.
NOTE: If you are using other units in the series with Rotel Link, please
use the Rotel Link connection to turn the units on or off. Do not connect
both the Rotel Link and 12V trigger cables. The 12V trigger’s power
on or off features will override the Rotel Link features.
Protection Indicator 2
The amplifier has both thermal and over-current protection circuitry that
protects the amplifier 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
amplifier if temperatures exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplifier 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 amplifier 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 amplifier 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 -and Ground Connection (GND) 0
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 =qw
The CD, Tuner, and Aux inputs of the amplifier 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.
Digital Signal Inputs ]
See Figure 4
There are two sets of digital inputs labeled 1 and 2 for COAXIAL and
OPTICAL respectively. Connect the COAXIAL or OPTICAL outputs of your
source component into these sockets. The digital signals will be decoded
and played by the amplifier. The unit is capable of decoding PCM signals
up to 24 bit, 192kHz.
Preamp Output [
The amplifier 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 amplifier or power
amplifier, 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 Outputs\a
See Figure 3
Speaker Selector Switch 5
The amplifier has two sets of speaker outputs, labeled “SPEAKER A” \and
“SPEAKER B” a. The speaker outputs are controlled by the A-B speaker
selector buttons 5on 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.

13
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 amplifier 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 amplifier connection.
Speaker Connection
Turn off all the components in the system before connecting the speakers.
The amplifier 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 amplifier 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
firmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent
wires or connectors.
Headphone Output 4
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 5or 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 6
The front panel display shows the source selected, volume level and tone
settings. The display provides access to the setup and conguration menu
options of the amplier.
Front USB Input 3
The front USB input can be connected to an iPhone, iPad or iPod device
providing music playback to the amplier. To enable audio playback using
one of these devices simply plug the device into the front USB and select
USB as the desired source. The device will remain active allowing search
and play functions.
APTX Bluetooth Connection e
The Bluetooth Antenna e on the A14’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 A14’s supports both traditional Bluetooth and APTX
Bluetooth audio streaming.

Troubleshooting
Most difficulties in audio systems are the result of incorrect connections, or
improper control settings. If you encounter problems, isolate the area of the
difficulty, 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 illuminate, 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 illuminate 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 amplifier inputs are connected properly.
Be sure the Input Source is set to the proper input. Check the wiring between
the amplifier and the speakers.

A propos de Rotel
Notre histoire commence il y a environ 50 ans. Depuis, au l des années,
nous avons reçu des centaines de prix et de récompenses, et satisfait des
centaines de milliers de personnes – comme vous !
Rotel a été fondée par une famille passionnée de musique, qui a décidé de
fabriquer des maillons Haute Fidélité sans compromis aucun.
Depuis sa création, cette passion est restée intacte, et cette famille s’est
xée comme objectif de proposer à tous les audiophiles et mélomanes
les meilleurs appareils possibles, quel que soit leur budget. Une volonté
partagée par tous les employés de Rotel.
Les ingénieurs Rotel travaillent comme une équipe très soudée, écoutant,
peaunant chaque nouveau modèle jusqu’à ce qu’il atteigne exactement
leurs standards – très élevés – de musicalité. Ils sont libres de choisir des
composants en provenance du monde entier, an de concevoir le meilleur
produit possible. C’est ainsi que vous trouverez dans nos appareils des
condensateurs d’origine britannique ou allemande, des transistors japonais
ou américains, tandis que les transformateurs toriques sont toujours fabriqués
dans nos propres usines Rotel.
Nous sommes tous concernés par la qualité de l’environnement. Et, comme de
plus en plus de produits électroniques sont fabriqués puis éliminés quelques
années plus tard, il est désormais essentiel qu’un constructeur fabrique tous
ses produits en veillant à ce qu’ils aient un impact minimum sur la Terre et
les nappes phréatiques.
Chez Rotel, nous sommes très ers d’apporter notre pierre à ce nouvel
édice. Nous avons réduit la teneur en plomb de nos électroniques, en
utilisant notamment une soudure spéciale ROHS, tandis que notre nouvelle
gamme d’amplicateurs fonctionnant en classe D (non numérique) présente
un rendement cinq fois supérieur aux générations conventionnelles
précédentes, délivrant pourtant encore plus de puissance, avec une qualité
encore supérieure. Ces appareils ne chauffent pas, dépensent beaucoup
moins d’énergie, sont donc très bons pour l’environnement tout en étant
encore plus musicaux.
En plus, nous imprimons tous nos catalogues et manuels sur papier recyclé.
Ce ne sont certes que de petites étapes. Mais ne sont‑ce pas justement les
plus importantes ? Nous continuons activement la recherche et la mise au
point de nouvelles méthodes, et l’utilisation de nouveaux matériaux pour
aboutir à un processus de fabrication général plus écologique et plus propre.
Tous les membres de l’équipe Rotel vous remercient pour l’achat de cet
appareil. Nous sommes persuadés qu’il vous offrira de nombreuses années
d’intense plaisir musical.
