A Word About Watts

This amplier’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 amplier’s power capability.

When comparing specications for different products, you should be

aware that power output is often specied 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 amplier, 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 ampliers 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 Amplier.

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 amplier.

Please read this manual carefully. In addition to basic installation and

operating instructions, it provides valuable information on various RA-1572

system congurations 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 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, 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 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 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 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 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 Amplier

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 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 RA‑1572 to another country, it is possible

to recongure your amplier 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 qualied

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

amplier (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 amplier 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 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

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 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 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

See Figure 4

Connect this input using the supplied USB cable to the USB socket of your

computer.

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”.

• Power cycle the RA-1572 and reboot your PC after changing the USB

Audio mode to ensure both units are properly congured.

Many audio playback applications do not support 384kHz sampling rate.

Please conrm your audio player supports 384kHz audio and you have

384kHz audio les to properly playback this sample rate. Also, you may

need to congure 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.

RA‑1572 Stereo Integrated Amplier

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.

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.

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

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.

doit être positionné dans un espace ouvert qui permet de garder l‘accès

au câble d’alimentation.

Cet appareil doit être branché sur une prise d’alimentation secteur, d’une

tension et d’un type conformes à ceux qui sont indiqués sur la face arrière

de l’appareil (USA : 120 V/60 Hz, CE : 230 V/50 Hz).

Brancher l’appareil uniquement grâce au cordon secteur fourni, ou à

un modèle équivalent. Ne pas tenter de modifier ou changer la prise.

Ne pas utiliser de cordon rallonge.

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,

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 ers d’apporter notre pierre à ce nouvel édice.

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.
