Important Safety Instructions
WARNING: The rear panel power cord connector is the mains
power disconnect device. The apparatus must be located in an
open area that allows access to the cord connector.
The unit must be connected to a power supply only of the type and
voltage specified on the rear panel. (USA: 120 V/60Hz, EC: 230V/50Hz)
Connect the component to the power outlet only with the supplied
power supply cable or an exact equivalent. Do not modify the
supplied cable. A polarized plug has two blades, with one wider than
the other. A grounding plug has two blades plus a third grounding
prong. These are provided for your safety. Do not defeat grounding
and/or polarization safety provisions. If the supplied plug does not
fit your outlet, please consult an electrician for replacement of the
obsolete outlet. Do not use extension cords.
The main plug of the power cordset is a disconnect device of the
apparatus. In order to completely disconnect the apparatus from the
supply mains, the main plug of the power cordset should be unplugged
from the mains (AC) outlet. The standby LED indicator will not be lit
up to show the power cord is unplugged. The disconnect device shall
remain readily operable.
Do not route the power cord where it will be crushed, pinched,
bent, exposed to heat, or damaged in any way. Pay particular
attention to the power cord at the plug and where the cord exits
the back of the unit.
The power cord should be unplugged from the wall outlet during
a lightning storm or if the unit is to be left unused for a long
period of time.

About Rotel
Our story began over 50 years ago. Over the decades, we have received
hundreds of awards for our products and satisfied hundreds of thousands
of people who take their entertainment seriously - like you!
Rotel was founded by a family whose passionate interest in music led
them to manufacture high-fidelity components of uncompromising quality.
Through the years, that passion has remained undiminished and the family
goal of providing exceptional value for audiophiles and music lovers,
regardless of their budget, is shared by all Rotel employees.
RotelÊs engineers work as a close team, listening to, and fine tuning, each
new product until it reaches their exacting musical standards. They are
free to choose components from around the world in order to make that
product the best they can. You are likely to find capacitors from the United
Kingdom and Germany, semiconductors from Japan or the United States,
while toroidal power transformers are manufactured in RotelÊs own factory.
We all have concerns about our environment. And, as more and more
electronics are produced and later discarded, it is especially important for
a manufacturer to do all it can to engineer products that have a minimum
negative impact on landfill sites and water tables.
At Rotel, we are proud to do our part. We have reduced the lead content
in our electronics by using special ROHS solder, while our new Class D
(not digital) amplifiers are up to five times more efficient than our legacy
designs and still deliver power and performance. These products run
cool, give minimum wasted energy, are good for the environment and
give better sound too.
Finally, we have printed this manual on recycled paper stock.
While we understand that these are small first steps, they are still important
ones. And we continue to pursue new methods and materials for a cleaner
and greener manufacturing process. All of us at Rotel thank you for buying
this product. We are sure it will bring you many years of enjoyment.
A Word About Watts
This amplifierÊs power output is quoted 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 RotelÊs experience,
it gives the truest value of the receiver or amplifierÊs power capability.
When comparing specifications for different products, you should be
aware that power output is often specified 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 figure.
A loudspeakerÊs impedance rating indicates the electrical resistance or
load it offers when connected to the amplifier, 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 amplifiers 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.

8RA-1570 Stereo Integrated Amplifier
Getting Started
Thank you for purchasing the Rotel RA-1570 Stereo Integrated Amplifier.
When used in a high-quality music audio system, it will provide years
of musical enjoyment.
The RA-1570 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-1570 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-1570 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-1570 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 RA-1570 are easy to install and use. If you
have experience with other stereo systems, you shouldnÊt 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
loudsp-eakers 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. In addition to basic installation and
operating instructions, it provides valuable information on various RA-1570
system configurations 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 RA-1570 shipping carton and all enclosed packing material for
future use. Shipping or moving the RA-1570 in anything other than the
original packing material may result in severe damage to your amplifier.
Fill out and send in the ownerÊs registration card packed with the RA-1570.
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-1570
can be affected by its environment. Avoid placing the RA-1570 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-1570 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 RA-1570 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-1570 is supplied with an RR-AX92 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 regular
audio signal cables in your installation away from each other. This will
minimize the chance of the regular 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-AX92 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX92 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.
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.
Remote Control Batteries
Two UM-4/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-AX92. 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 wonÊt
operate the RA-1570 consistently. Installing fresh batteries should eliminate
the problem.
AC Power and Control
AC Power Input
i
Because of its relatively high power rating, the RA-1570 can draw
considerable current. Therefore, 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) is
rated to handle the current demanded by the RA-1570 and all the other
components connected to it.
Your RA-1570 is configured at the factory for the proper AC line voltage
in the country where you purchased it (either 120 volts AC or 230

9
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 RA-1570 to another country, it is
possible to reconfigure your amplifier for use on a different line
voltage. Do not attempt to perform this conversion yourself. Opening
the enclosure of the RA-1570 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.
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 and Power Indicator
1
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 may be used to activate the RA-1570. In Standby mode
the power LED remains lit, but the display is turned OFF.
12V TRIGGER Connection
u
Some audio components can be turned on automatically when they receive
a 12V turn on „signal‰. The two12V Trigger Outputs of the RA-1570
provide the required signal. Connect compatible components to the RA-
1570 with a conventional 3.5mm mini plug cable. When the RA-1570
is in turn off mode, 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 triggerÊs power
on or off features will override the Rotel Link features.
Input Signal Connections
See Figure 3,4,5
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
0
and Ground Connection (GND)
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
0
See Figure 3
The CD, Tuner, and Aux inputs of the amplifier 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-1570. Ask your authorized
Rotel dealer for advice about cables.
Balanced (XLR) Inputs
=
See Figure 4
A pair of balanced XLR inputs accept audio signals from CD player, Blu-
ray player or other source components with XLR outputs.
NOTE: You should choose only one method of ananlog connection
from a source component to RA-1570. Do not connect both the
RCA and XLR outputs of a source component to the RA-1570 at the
same time.
Digital Signal Inputs
q
See Figure 5.
There are two sets of digital inputs labeled COAX 1 and 2, OPT 1
and 2. Connect the COAXIAL or OPTICAL PCM 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 Outputs
-
The amplifier has a set of preamp outputs labeled PREOUT 1. The signal
from the source selected with the Function Selector is always available
from these outputs. Typically the PREOUT 1 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 Outputs.
Preamp / Power Amp Jumpers
ey
ey
These connectors, labeled ‰Pre Out 2‰ and „Main In‰, are normally
connected by a set of solid metal jumper connectors. They provide a
convenient insertion point for virtually any type of signal processor. To
use these connectors, pull out the jumper connectors. Using high quality
cables, connect the „Pre Out 2‰ connectors to the inputs of the signal
processor. Connect the outputs of the signal processor to the „Main In‰
connectors.

10 RA-1570 Stereo Integrated Amplifier
Speaker Outputs
r
See Figure 3
The RA-1570 has two sets of speaker outputs, labeled SPEAKER A and
SPEAKER B. The speaker outputs are controlled by the switch
7
on the
front panel and the buttons Oon 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-1570. See your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1570 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 ăthe positive/negative orientation of the connections ăfor
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 Connections
r
Turn off all the components in the system before connecting the speakers.
The RA-1570 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-1570 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 firmly in place.
NOTE: Be sure there are no loose wire strands that could touch
adjacent wires or connectors.
PHONES Output
5
The Phones output allows you to connect headphones for private listening.
This output accommodates standard stereo phone (1/8‰) plugs. Plugging
in a set of headphones does not cut off the signal to the speakers. Use
the Speaker Selector to turn off the speakers. The settings of the Function
Selector determines which source is heard.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.

useful when the unit is installed in a cabinet and the front-panel sensor is
blocked. Consult your authorized Rotel dealer for information on these
external repeaters and the proper wiring of a jack to fit the mini-jack
receptacle.
Protection Circuit
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
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.
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 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 RA-1570, 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-1570 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 light when the RA-1570 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 RA-1570 inputs are connected
properly. Check the wiring between the RA-1570 and the speakers.

关于洛得
洛得已有超过50年的历史。几十年来，我们的产品已赢得数百次奖项，
满足了无数对娱乐有着严肃态度的人士－比如您。
洛得是一个家族公司，他们对音乐的激情让他们致力于制造高品质的高保
真音响设备。多年以来，这种激情丝毫未减，而为不同预算的高保真音响
发烧友和音乐爱好者提供超值产品的目标，是洛得所有员工的共同追求。
洛得的工程师紧密协作，认真倾听并精确调谐每个新产品，直到其符合
苛刻的音乐标准。他们从世界各地选择部件，以令其产品尽善尽美。您
可能会发现英国和德国生产的电容器、日本和美国产的半导体，以及洛
得自己的工厂制造的环形功率变压器。
我们十分关注环境。随着越来越多的电子产品出现，随后被废弃，制
造商竭尽所能设计对垃圾填埋场和地下水位带来最低负面影响的产品
就显得尤为重要。
在洛得，我们做到了这一点，我们对此深感自豪。通过使用特殊的ROHS
焊料，我们降低了电子产品中的铅含量，同时，我们最新的D类（非数
码）放大器的效率是传统设计的五倍之多，同时仍可提供大功率和很
高的性能。这些产品运行时温度低，能源浪费少，不损害环境，并带
来更好的音质。
最后，我们用可回收的纸张印刷本手册。
虽然我们知道这些事情微不足道，但它们对环保仍然非常重要。我们
会继续寻找新的方法和材料，开发更加清洁、更加环保的制造工艺。
洛得的全体同仁感谢您购买本产品。我们深信，本产品将为您带来数
年的美妙享受。
功率简介
两个声道均以最大功率运作时，本放大器的额定功率输出为每声道120W。
根据洛得的经验，这个功率可提供接收机或放大器功率容量最真实的数
值，因此，洛得选择以这种方式标注功率输出。
与其它产品的规格参数相比，您会发现它们通常以其它方式标注功率输
出，让您无法对其它进行比较。例如，它们提供的功率输出可能只是一
个声道工作时的功率输出，从而给出一个更高的最大数值。
音箱的额定阻抗表示它们连接到放大器时提供的电阻或负荷，通常为8Ω
或4Ω。阻抗越低，音箱需要的功率更高。实际上，一只阻抗为4Ω的音
箱所需要的功率为8Ω音箱的两倍。
但是，洛得放大器的设计可使用阻抗介于8Ω和4Ω之间的任何音箱，所
有声道均可以最大功率运作。由于洛得的设计已针对所有声道同时工作
进行了优化，洛得可为两个声道指定真正的功率输出。
