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 amplier in anything other than the original packing
material may result in severe damage to your amplier.
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 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 airow 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.
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 nd that the remote is conicting
with other Rotel ampliers, you can change to remote code 2 with the
following steps.
1. From the remote control press Tuner
I
and 2
M
at 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
M
button for 14 seconds. The
unit will show “Audio Code SET 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 A12 consistently.
Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input
a
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 amplier 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.

and Power Indicator
2
Press the front panel Power Switch button
1
to turn the unit on. The Power
Indicator light
2
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 may be used to activate the A12. 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 A12 unit provide
the required signal. Connect compatible components to the amplier 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 amplier 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.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplier 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 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 2 should 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 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.
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 amplier. The unit is capable of decoding PCM signals
up to 24 bit, 192kHz.
Preamp Output
p
The amplier 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 amplier or power
amplier, 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
]\
See Figure 3
Speaker Selector Switch
5
The amplier has two sets of speaker outputs, labeled “SPEAKER A”
]
and
“SPEAKER B”
\
. The speaker outputs are controlled by the A-B speaker
selector buttons
5
on the front panel or J on 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.
13
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.
Speaker Connection
Turn off all the components in the system before connecting the speakers.
The amplier 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 amplier 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
4
The headphone output allows you to connect headphones for private listening.
This output accepts a standard 3.5mm (1/8”) mini stereo headphone

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 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 amplier inputs are connected properly.
Be sure the Input Source is set to the proper input. Check the wiring between
the amplier 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 planète.
Chez Rotel, nous sommes très fiers d’apporter notre pierre à ce nouvel édifice.
Nous avons réduit la teneur en plomb de nos électroniques, en utilisant
notamment des composants et une soudure spéciale ROHS. Nos ingénieurs
travaillent en permanence pour améliorer le rendement des alimentations de
puissance sans compromettre leur qualité. C’est ainsi qu’en mode Standby,
les appareils Rotel consomment moins pour se conformer aux exigences
de la « Standby Power Consumption » qui limite la consommation en veille
des appareils électroniques.
L’usine Rotel participe également de façon active à la protection de
l’environnement au travers d’un processus de fabrication général amélioré
et toujours 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.

A12 Amplicateur Stéréo Intégré
Les cartes électroniques (PCB) sont conçues sur le principe de circuits
symétriques (Symmetrical Circuit Traces), pour garantir une synchronisation
parfaite du signal musical, et donc une restitution optimale. Les circuits
utilisent des résistances à ls métalliques, et des condensateurs polystyrènes
ou polypropylènes sur les circuits les plus critiques. Tous les aspects de la
conception de l’appareil ont été rigoureusement étudiés pour garantir une
reproduction musicale la plus dèle possible.
Toutes les fonctions principales du A12 sont faciles à congurer et à utiliser.
Si vous avez déjà l’expérience d’autres systèmes stéréo, vous ne devriez pas
rencontrer de difcultés particulières. Connectez simplement les composants
associés, et protez de votre musique.
Quelques précautions préalables
AVERTISSEMENT : Pour éviter d’endommager potentiellement votre
système, veillez à bien mettre hors tension TOUS les éléments lorsque
vous branchez ou vous débranchez les enceintes acoustiques et les
composants associés. Ne mettez pas les appareils en marche tant vous
n’êtes pas certain que tous les branchements sont corrects et sécurisés.
Prêtez une attention particulière aux câbles des enceintes acoustiques.
Il ne doit y avoir aucun l qui puisse entrer en contact avec les autres
câbles d’enceintes ou avec le châssis de l’amplicateur.
Merci de lire soigneusement ce manuel. Il vous donne des renseignements
utiles sur la meilleure façon d’intégrer votre A12 au sein de votre système ainsi
que des informations qui vous aideront à obtenir les meilleures performances
sur le plan sonore. N’hésitez pas à contacter votre revendeur agréé Rotel
pour obtenir les réponses à toutes les questions que vous pourriez vous
poser. En outre, nous sommes toujours heureux, chez Rotel, de recevoir
vos toutes vos remarques et commentaires.
Conservez soigneusement le carton de votre amplicateur intégré et tous
les éléments servant à l’emballage pour un usage futur éventuel. En effet,
expédier ou déménager votre appareil dans quoique ce soit d’autre que son
carton d’origine peut avoir pour conséquence d’endommager gravement
votre amplicateur.
Remplissez et renvoyez la carte d’enregistrement du propriétaire qui est jointe
à votre produit, et conservez en lieu sûr la facture originale. Elle constitue
votre meilleure preuve de date d’achat au cas où vous auriez besoin de
faire appliquer la garantie constructeur.
Installation
Comme tous les appareils audio faisant transiter des signaux de faible
niveau, le A12 pourra être affecté par son environnement. Évitez de disposer
l’amplicateur sur d’autres éléments du système. Éviter également de faire
passer les câbles transportant le signal audio à proximité des cordons
secteur. Cela réduira au minimum les problèmes potentiels de parasites
ou de bruit de fond.
L’appareil génère de la chaleur pendant son fonctionnement normal. Les
ouïes de refroidissement et la ventilation interne de l’amplicateur sont
conçues pour dissiper la chaleur. Les ouïes de refroidissement sur le dessus de
l’appareil doivent rester libres. Il doit y avoir environ 10 cm de dégagement
tout autour de lui pour permettre le bon fonctionnement de sa ventilation et
une bonne circulation d’air tout autour du meuble qui le supporte.
Prenez en compte le poids et les dimensions de l’appareil lorsque vous le
disposez sur une étagère, un meuble ou dans un rack, et vériez que ceuxci
sont bien en mesure de supporter son poids. Nous vous conseillons de
disposer le A12 dans un meuble conçu pour recevoir des appareils audio
domestiques. De tels meubles sont spécialement fabriqués pour réduire
ou supprimer les vibrations qui peuvent affecter la qualité sonore. Prenez
conseil auprès de votre revendeur agréé Rotel sur un choix du meuble et
pour une installation correcte de vos éléments audio.
Câbles
Les cordons secteur, les câbles numériques et les câbles de modulation
transportant le signal audio devront être si possible éloignés les uns des
autres. Cela pour réduire au minimum le risque que le signal audio puisse
être affecté par des interférences ou du bruit de fond provenant des câbles
secteur ou numériques. Utilisez uniquement des câbles de haute qualité.
Les câbles blindés sont particulièrement indiqués pour réduire le bruit de
fond et les parasites qui viendraient dégrader la qualité sonore de votre
système. Pour toutes ces questions, consultez votre revendeur agréé Rotel,
qui pourra vous conseiller sur le choix du meilleur câble à utiliser avec
votre système audio.
Télécommande infrarouge RR-AX1400
Les commandes peuvent être effectuées depuis les boutons de la face avant,
ou via la télécommande RR-AX1400 qui est fournie avec l’appareil. Dans ce
manuel, les lettres et nombres entourés d’un carré se réfèrent aux commandes
exécutables au niveau de la face avant de l’appareil et, respectivement,
celles qui sont entourés d’un rond par la télécommande.
Code secondaire de télécommande
Le code de télécommande usine par défaut est le code 1. Si vous constatez
que la télécommande est en conit avec d’autres amplicateurs Rotel,
vous pouvez changer le code et mettre en place le code 2 en suivant les
instructions ci-dessous:
1. Sur la télécommande appuyez sur « Tuner »
I
et sur « 2 »
M
en même
temps pendant 5 secondes, pour que la télécommande puisse envoyer
le Code Audio 2.
2. Pointer la télécommande vers l’appareil et appuyez sur « 2 »
M
pendant
14 secondes. L’appareil va alors afcher « AUDIO CODE SET 1 -> 2 ».
3. Recommencez la procédure et appuyez sur « 1 » au lieu de « 2 » pour
remettre l’appareil sur le Code 1.
Remarque : Vous pouvez utiliser votre télécommande pour le pilotage
des fonctions de base de tuners et de lecteurs de CD Rotel, notamment
par les groupes de touches repérées
GHMN
. Pour un fonctionnement
correct de votre système, assurez-vous que la télécommande, le lecteur
de CD et le Tuner, utilisent bien tous le même code de télécommande,
soit le Code 1 ou soit le Code 2.
Piles de la télécommande
Deux piles de type AAA (fournies) doivent être insérées dans la télécommande
au préalable à son utilisation. Pour mettre en place les piles, enlevez le
couvercle situé à l’arrière de la RR-AX1400. Insérez les piles comme indiqué
sur la Figure. Faites un test de fonctionnement, puis remettez le couvercle
en place. Lorsque les piles deviennent faibles, la télécommande ne pourra
plus piloter correctement le A12. Installez alors des piles neuves pour
éliminer le problème.
