A Word About Watts
This amplier’s power output is rated as 120 watts for each channel, when
both channels are operating together at full power. Rotel has chosen to
specify the power output in this way because, in Rotel’s experience, it gives
the truest value of the receiver or amplier’s power capability.
When comparing specications for different products, you should be
aware that power output is often specied in other ways, so you may not
be comparing like with like. For example, the power output may be quoted
with only one channel operating, giving a higher maximum gure.
A loudspeaker’s impedance rating indicates the electrical resistance or
load it offers when connected to the amplier, usually 8 ohms or 4 ohms.
The lower the impedance, the more power the speaker will need. In effect,
a 4 ohm speaker will require twice as much power as an 8 ohm speaker.
However, Rotel ampliers are designed to work into any speaker impedance
between 8 and 4 ohms, and with all the channels working up to their full
power. Because Rotel designs are optimized for use with all channels operating
together, Rotel is able to specify the true power output for both channels.
Getting Started
Thank you for purchasing the Rotel RA-1572 Stereo Integrated Amplier.
When used in a high-quality music audio system, your Rotel product will
provide years of musical enjoyment.
The RA-1572 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 RA-1572 has a highly regulated power
supply incorporating a Rotel custom-designed toroidal power transformer
and custom-made slit foil capacitors. This low impedance power supply has
ample power reserves, which enables the RA-1572 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 RA-1572 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 RA-1572 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 amplier.
Please read this manual carefully. In addition to basic installation and
operating instructions, it provides valuable information on various RA-1572
system congurations as well as general information that will help you get
optimum performance from your system. 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 RA-1572 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, the RA-1572 can
be affected by its environment. Avoid placing the RA-1572 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 RA-1572 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 RA-1572 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 RA-1572 is supplied with an RR-AX93 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 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‑AX93 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX93 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 K and 2 O at the same time for 5
seconds, to set the remote control to send Audio Code 2.
12
RA‑1572 Stereo Integrated Amplier
2. Point the remote at the unit and press 2 O button 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 buttons labeled
FIJNOQ 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-AX93. 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 RA-1572
consistently. Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input
\
Your RA-1572 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 RA‑1572 to another country, it is possible
to recongure your amplier for use on a different line voltage. Do not
attempt to perform this conversion yourself. Opening the enclosure of
the RA‑1572 exposes you to dangerous voltages. Consult a qualied
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.
Because of its relatively high power rating, the RA-1572 can draw considerable
current. Therefore, it should be plugged directly into a polarized wall
outlet using the supplied cable or other high current 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) is rated to handle the current demanded by the RA-1572 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.
POWER Switch and Power Indicator
1
A
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 A may be used to activate the RA-1572. In Standby mode the
power LED remains illuminated, but the display is turned off.
12V TRIGGER Connection
[
See Figure 7
Some audio components can be turned on automatically when they receive
a 12V turn on signal. The two 12V Trigger Outputs of the RA-1572 provide
the required signal. Connect compatible components to the RA-1572 with
a conventional 3.5mm mini plug cable. When the RA-1572 is in standby
mode or turned off, the trigger signal is interrupted, so 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.
Input Signal Connections
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
See Figure 3
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
-
See Figure 3
The CD, Tuner, and Aux inputs of the amplier are analog “line level” inputs.
These inputs are for connecting components such as CD players or other
audio playback devices with an analog audio output.
The left and right channels are clearly 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 RA-1572. Ask your authorized
Rotel dealer for advice about cables.
Balanced (XLR) Inputs
w
See Figure 5
A pair of balanced XLR inputs accept audio signals from CD player, Blu-ray
player or other source components with XLR outputs.
13
NOTE: You should choose only one method of analog connection from
a source component to RA‑1572. Do not connect both the RCA and
XLR outputs of a source component to the RA‑1572 at the same time.
Digital Signal Inputs
e
See Figure 4
There are two sets of digital inputs labeled 1 and 2 for COAXIAL and
OPTICAL respectively. Connect the COAXIAL or OPTICAL PCM outputs of
your source component into these sockets. The digital signals will be decoded
and played by the RA-1572. The unit is capable of decoding PCM signals
up to 24 bit, 192kHz.
Output Connections
MONO SUB Output
=
There are 2 connectors for mono subwoofer output to connect to a subwoofer.
These mono outputs are summed with both the left and right audio signal. They
are parallel outputs allowing 2 subwoofers to be connected to the RA-1572.
Preamp Output
q
The RA-1572 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 Outputs
i
See Figure 3
The RA-1572 has two sets of speaker outputs, labeled SPEAKER A and
SPEAKER B. The speaker outputs are controlled by the A-B speaker selector
buttons
7
on the front panel and the buttons
L
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 RA-1572.
See your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1572 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.
Speaker Connections
i
Turn off all the components in the system before connecting the speakers.
The RA-1572 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 RA-1572 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. Place
the connector lug or wire around the binding post shaft. Turn the binding
post 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
5
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

The RA-1572 supports both USB Audio Class 1.0 and USB Audio Class
2.0 modes. Windows computers do not require installation of a driver for
USB Audio Class 1.0 and support playback of audio up to 96kHz sampling
rates. The Factory Default setting is USB Audio Class 1.0.
To take advantage of USB Audio Class 2.0 audio playback supporting
up to 384kHz sampling rates you will need to install the Windows driver
supplied on the CD included with the RA-1572. You will also need to switch
the RA-1572 to USB Audio Class 2.0 playback mode with the following:
• Press MENU on the front panel until “PC-USB AUDIO CLASS” appears
on the display.
• Select “2.0” using the “-” button then press “ENTER”.

Audio mode to ensure both units are properly congured.
Many audio playback applications do not support 384kHz sampling rate.
Please conrm your audio player supports 384kHz audio and you have
384kHz audio les to properly playback this sample rate. Also, you may
need to congure the audio driver in your PC to output 384kHz or your
computer may “down sample” to a lower audio sample rate. For more
information please refer to your audio player or operating system information.
NOTE: USB Audio Class 2.0 requires installation of the Windows PC
driver on the CD ROM included with the RA‑1572.
NOTE: MAC computers do not require a driver to support PC‑USB
1.0 or 2.0 audio.
NOTE: Upon successful installation of the driver, you may need to select
the ROTEL audio driver from the audio/speaker setup of your computer.

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.
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.
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 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
RA-1572, refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
The Power Indicator ring around the power button and the basic items in the
Display window should be illuminated whenever the RA-1572 is plugged
into the wall power outlet and the POWER switch 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 still will not illuminated when the RA-1572 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.

La prise d’alimentation secteur constitue le moyen radical de déconnexion
de l’appareil. Elle doit donc rester en permanence accessible, car sa
déconnexion constitue la seule assurance que l’appareil n’est plus
alimenté par le secteur.
Utilisez uniquement des câbles de Classe 2 pour réalise les connexions aux
enceintes acoustiques et offrant une isolation suffisante pour minimiser
les risques de chocs électriques.
Les piles de la télécommande infra‑rouge ne doivent en aucun cas
exposées à une chaleur excessive notamment au feu ou au soleil direct.

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,
peaunant 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, an 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 ers d’apporter notre pierre à ce nouvel édice.
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.
