Our story began nearly 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.
Rotel’s 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 Rotel’s 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 brochure 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.
Getting Started
Thank you for purchasing the Rotel RC‑1550 Stereo Control Amplifier.
When used in a high-quality music audio system, it will provide years
of musical enjoyment.
The RC-1550 is a full featured, high performance preamplifier. All
aspects of the design have been optimized to retain the full dynamic
range and subtle nuances of your music. The RC-1550 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 RC-1550 to easily reproduce the most demanding audio signals.
This type of design is more expensive to manufacture, but it is better
for the music.
RC-1550 Book.indb 6
23/2/09 16:06:04
English
The RC-1550 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 RC‑1550 circuitry
uses metal film resistors and polystyrene or polypropylene capacitors
in important signal paths. All aspects of this design have been
examined with the final goal being faithful reproduction of music.
The RC-1550 is straightforward in its installation and operation. If you
have experience with other stereo systems, you shouldn’t find anything
perplexing. Simply plug in the associated components and enjoy.
A Few Precautions
Please read this manual carefully. It provides complete information on
how to incorporate the RC-1550 into your system as well as general
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 RC-1550 shipping carton and all enclosed packing material
for future use. Shipping or moving the RC-1550 in anything other than
the original packing material may result in severe damage to your
amplifier.
Fill out and send in the owner’s registration card packed with the
RC-1550. 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.

Remote Sensor 2
The remote sensor receives infrared signals from the remote control.
Do not cover or block the sensor. It must be unobstructed or the remote
control will not work properly.
The operation of the remote sensor can also be affected if it is exposed
to bright sunlight or certain types of lighting (such as halogen lights)
that emit infrared light. In addition remote control functions may not
work reliably if the batteries in the RR-AT94 are weak.
Note: To use the remote, aim it at the remote sensor on the front panel
of the RC-1550.
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-AT94. 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-1520 consistently. Installing fresh
batteries should eliminate the problem.
AC Power and Control
AC Power Input u
Note: Be sure to set the Volume control to the minimum (full
counterclockwise) position before connecting the power cord.
Like all audio components that handle low-level signals, the RC-1550
can be affected by its environment. Do not stack the RC-1550 on top
of a power amplifier. This will minimize chance it will pick up hum
or interference. We recommend installing the RC-1550 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.
Connect the supplied power cord to the AC Input receptacle on the
rear panel. Do not connect the power cord to the power outlet until all
the audio input and output connections have been made.
Cables
Your RC-1550 is configured at the factory for the proper AC line
voltage in the country where you purchased it (either 120 volts AC or
230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC
line configuration is noted on a decal on the rear panel.
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.
Remote Control
The RC-1550 includes an RR-AT94 remote control that operates many
of the controls of the RC-1550. In addition, the remote operates
basic features of some Rotel CD players, DVD players, and AM/FM
tuners. See the “Audio Controls” and “Controlling Other Components”
sections of this manual for detailed information.
RC-1550 Book.indb 7
It is usually best to plug the RC‑1550 directly into a 2-pin polarized
wall outlet. Avoid the use of extension cords. 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 components connected to it.
Note: Should you move your RC-1550 amplifier 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 RC-1550 exposes you to dangerous voltages.
Consult a qualified service person or the Rotel factory service
department for information.
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.

STANDBY Switch and Indicator 1 and Remote POWER Switch E
The STANDBY switch 1 is located on the left side of the front panel.
To use the RC-1550, press the STANDBY switch. The switch button
will remain in its IN position and the ring around the Standby switch
will light. In addition the indicators above the selected Listening input
button 8 will light.
When the STANDBY switch is pushed in, you can turn the RC-1550
on, or put it in Standby mode, with the POWER button E of the
RR-AT94 remote control.
When the RC-1550 is in Standby mode, pressing one of the
RR‑AT94 Input Selector buttons B turns the unit on and selects the
corresponding input.
If you will not be using the RC-1550 for a long period of time, press
the front panel STANDBY switch to turn it Off. The button will return to
its Out position and all the front panel indicator lights will turn off.
Note: Be sure to set the Volume control to the minimum (full
counterclockwise) position before you push in the STANDBY switch.
Input Signal Connections = and q
[See Figure 3.]
The RC-1550 has conventional RCA-type connectors for all inputs.
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.
Line Level Inputs q
The CD, Tuner, and Aux inputs of the RC-1550 are “line level” inputs.
These are for connecting the analog outputs from components such
as CD players, DVD players, video disc recorders, tuners for audio or
video, or VCRs.
The Left and Right channels are clearly labeled and should be
connected to the corresponding channels of the source component.
The Left RCA connectors are white, the Right connectors are red. Use
high quality RCA cables for connecting input source components to the
RC-1550. Ask your authorized Rotel dealer for advice about cables.
Phono Input = and Ground Connection -
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.
Recorder Connections w
The Tape 1 and Tape 2 inputs and outputs can be connected to any
record/playback device that accepts standard line level analog input
and output signals. Typically that will be a conventional tape recorder.
When connecting a recorder to the RC-1550, remember that the
outputs of the recorder must be connected to the tape inputs of the
RC‑1550. Similarly the tape outputs of the RC-1550 must be connected
to the inputs of the recorder. As with other sources be sure to connect
the Left and Right channels of each device to the proper channels on
the associated components. Use high quality connecting cables to
prevent loss of sound quality.
Output Connections e
Most RCA-type output connectors are compatible with most power
amplifiers. As always, use high quality cables and be sure to connect
the Left and Right channel outputs of the RC-1550 to the correct
channels of the amplifier.
Note: There are two sets of RCA outputs on the RC-1550. The second
set of outputs may be used in custom system configurations to drive
a second power amplifier or to supply a signal to a special signal
processor.
IR Inputs and Outputs
External Remote Input r
This 3.5 mm mini-jack (labeled EXT REM IN) receives command codes
from an industry-standard infrared receivers located in the main
listening room. This feature is useful when the unit is installed in a
cabinet and the front-panel sensor is blocked. Consult your authorized
Rotel dealer for information on external receivers and the proper
wiring of a jack to fit the mini-jack receptacle.
Note: The IR signals from the EXTERNAL REMOTE IN jack can be
relayed to source components using external IR emitters or hard wired
connections from the IR OUT jacks.
IR Output t
The IR OUT 1 and 2 jacks send IR signals received at the EXTERNAL
REM IN jack to an infrared emitter placed in front of a source
component or to other Rotel components with compatible rear panel IR
input connectors.
This output is used to allow IR signals to pass along IR signals from
a remote control when the sensors on the source components are
blocked by installation in a cabinet.
See your authorized Rotel dealer for information on IR repeater
systems.
NOTE: The EXT REM IN jack located next to these jacks is for use with
an external IR sensor duplicating the front panel IR sensor and located
in the primary zone.

12V Trigger Connections y
Audio Controls
Many Rotel amplifiers offer the option of turning them on and off using
a 12 volt trigger signal sent to them. The RC-1550 provides a 12 volt
trigger output to take advantage of this feature. When the RC‑1550
is turned on, a 12 volt DC signal is sent to the amplifier to turn them
on. When the RC‑1550 is put in STANDBY mode, the trigger signal is
interrupted and the amplifiers turn off.
Volume Controls 5 and C
To use the remote turn on feature, connect the RC‑1550 12V TRIGGER
OUT jack to the 12 volt trigger input of a Rotel amplifier, using a cable
with mono 3.5 mm mini-plugs on both ends. The +12 V DC signal
appears at the “tip” connector.
Phones Output 0
The Phones output allows you to connect headphones for private
listening. This output accommodates standard 1/8” stereo mini plugs.
If your headphones have a 1/4” plug you will need an adapter plug.
Contact your authorized Rotel dealer, to get the correct adapter plug.
Note: Plugging in a set of headphones does not cut off the signal to
the outputs. In most instances you should turn off the power amplifier
when listening to headphones.
Media Player Input 9
A 3.5mm (1/8”) stereo input socket for a “Media Player” is
provided on the front of the RC-1550. To select it, turn the front panel
LISTENING control 8 to AUX or press the AUX 1 button B on the
RR-AT94 remote control.
Any portable stereo cassette, compact disc player or hard disc
playback device can be connected via this input. If the Media Player
input is connected to the headphone outputs of the player note that
you may need to adjust the volume control on the player for sound to
be heard. If the sound is loud and distorted turn down the volume on
the player. If the sound is not loud enough, even when the RC-1550
volume control is turned up fairly high, then carefully turn up the
volume control on the player.
Note: When the 3.5mm (mini jack) is inserted into the Media Player
socket the rear input called AUX is disconnected. Removing the 3.5mm
plug from the Media player socket will allow the rear AUX input to
function.
The front panel Volume control 5 increases or decreases the volume
in both channels at the same time. Turn it clockwise to increase the
volume or counterclockwise to decrease the volume. On the RR-AT94
remote use the Volume + and – buttons C to increase or decrease the
volume level.
Mute Button A
Remote Only
Push the MUTE button on the remote once to turn the sound off. Press
the button again to restore previous volume levels. The LED in the
volume control will flash when the unit is muted.
Note: Pressing the volume buttons on the remote also cancels the
muting function.
Balance Control 6
The Balance Control adjusts the left-to-right balance of the sound
output. Normally the control should be in the center position. In some
situations, typically when the main listening position is not ideally
centered between the speakers, it may be necessary to adjust the
control to achieve proper left-to-right balance. Turning the control
counter-clockwise shifts the sound balance to the left. Turning the
control clockwise shifts the sound balance to the right.
Tone On/Off Switch 4
When the Tone Switch is in the Off (out) position the Bass and Treble
Control circuits are bypassed to ensure the purest possible sound.
Leave the Tone Switch in the Off position unless you want to use the
Tone Controls. Push in the Tone Switch if you want to adjust the Tone
Controls.
Bass and Treble Controls 3
When the Tone Switch is pushed in, turning the Bass and Treble
Controls adjusts the tone balance of the sound. Turn the Controls
clockwise to increase the bass or treble output. Turn the Controls
counterclockwise to decrease the bass or treble output.
A properly set up high-performance audio system produces the most
natural sound with little or no adjustment of the tone controls. Use
these controls sparingly. Be particularly careful when turning the
controls up (clockwise). This increases the power output in the bass or
treble range, increasing the load on the amplifier and speakers.
Listening Selector Controls 8B
Turn the front panel control 8, or press one of the remote control
buttons B, to select the input signal that goes to the main outputs and
to the power amplifier – or, more simply, which source is heard.

Recording Selector Control 7
Front panel only
Turn the front panel control 7 to select the input signal that goes to
the record outputs. When you are not recording, set the control to Off.
This minimizes the chance of interference from other components in the
system.
Having a separate Recording and Listening selector adds a significant
degree of flexibility in how you can use the RC-1550. For example
by selecting CD with the Record Selector and selecting Tuner with the
Listening Selector you can record a CD onto a tape while listening to
the tuner.
If you have a three-head recorder or a DAT recorder that allows
simultaneous read and write operation, you can monitor the recording
by setting the LISTENING control 8 to the Tape 1 or Tape 2 position.
Note: If you select TAPE 1 with the RECORDING control 7, the
recording signal will only be available at the TAPE 2 recording
outputs. To copy a tape from one tape recorder to another, connect
the source recorder to the TAPE 1 inputs and outputs and set the
RECORDING control to Tape 1. Connect tape recorder you are
copying to to the Tape 2 inputs and outputs.
Controlling Other Components
In addition to operating many of the controls of the RC-1550, the
RR-AT94 remote control can operate basic features of some Rotel CD
players, DVD players, and AM/FM tuners.
CD Functions DG
The / PLAY, . STOP, , PAUSE, { } TRACK and, RANDOM
buttons, and NUMERIC buttons (0 - +10) operate many Rotel CD
players after the CD button on the remote has been pressed.
DVD Functions DG
The / PLAY, . STOP, , PAUSE, { } TRACK and RANDOM buttons
operate Rotel DVD players, after the AUX1 button on the remote has
been pressed.
Tuner Functions F
The BAND, TUNING < >, and additional tuning feature buttons (PTY,
TA, TP, etc.) operate Rotel tuners, after the TUNER listening button on
the remote has been pressed.
Note: By default, the RR-AT94 operates the Rotel RT-1080/RT‑1082/
RT-1084 tuners. The remote can be reprogrammed to operate the
RT‑940AX tuner. This programming only needs to be done once:
To program for the RT-940AX: press the POWER button and the
2 button simultaneously.
To program for the RT-1080/RT‑1082/RT-1084: press the
POWER button and the 1 button simultaneously.
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 RC-1550, refer to the suggestions for the following conditions:
Standby Power Indicator Is Not Lit
The Standby Power Indicator should be lit whenever the RC-1550 is
plugged into the wall power outlet. 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,
and the Standby Indicator still will not light when the RC-1550 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 RC-1550 inputs are connected
properly. Be sure the Listening Selector is set to the proper input. Check
the power amplifier for power and proper operation. Check all the
wiring between the RC-1550 and the power amplifier, and the power
amplifier and speakers.
Remote Control Code Conflicts
Rotel uses the same IR remote control codes for all its audio products.
In systems that have multiple Rotel products, the IR control codes of a
remote control that is supplied with one product may interfer with the
control codes of another product. The RR-AT94 and the RC-1550 can
be set to alternate control codes to prevent such conflicts.
To change the IR codes of the RR-AT94, press the Phono button and
the 2 button at the same time. To change the IR codes of the RC-1550,
point the RR-AT94 at the RC-1550 then press and hold the 2 button for
5 seconds. The LED in the volume control will flash to indicate the IR
code has changed.
Note: After changing the remote codes for the remote control and
the preamplifier as described above, the remote control will no
longer operate the Rotel tuners. To return the RR-AT94 IR code to the
default setting, press the Phono button and the 1 button at the same
time. To return the IR code of the RC-1550 to the default setting,
point the RR‑AT94 at the RC‑1550 and press and hold the 1 button
for 5 seconds. The LED in the volume control will flash to indicate the
IR code has changed.
Resetting the IR codes
Should you need to reset the IR code, press the MUTE button A on the
RR-AT94 remote control for more than 5 seconds while pointing it at
the RC-1550. The unit will return to default condition and the Listening
CD LED 8 will turn on to indicate the IR code is reset. Contact your
authorized Rotel dealer for further information.

均衡控制
均衡控制可调整声音输出的左-右均衡。通常，本控制旋钮
应置于中间位置。有些情况下，一般是在主要听音位置不
是位于音箱之间的正中间时，可能有必要调整该旋钮以获
得适当的左右均衡。逆时针旋转控制钮将声音均衡调到左
边。顺时针旋转控制钮将声音均衡调到右边。
音调开/关开关
音调开关位于关（出来）的位置时，重低音和高音高音控
制电路被旁通，以获得最纯净的声音。除非您想使用音调
控制，否则应将音调开关调到关的位置。如果您想调节音
调控制旋钮，按下音调开关。
重低音和高音高音控制
音调开关被按下去时，调整重低音和高音高音控制以调整
声音的音调平衡。顺时针调整控制钮提高重低音或高音高
音输出。逆时针调整控制钮降低重低音或高音高音输出。
经过适当设置的高性能音频系统可产生最自然的声音，而
无需调整或只需作细微调整。请谨慎使用这些控制。向上
调整（顺时针）控制钮时请特别小心。这将加大重低音或
高音范围的功率输出，从而增加放大器和音箱的负载。
收听选择控制
旋转前面板上的旋钮□ ，或按遥控器上按键 中的一个，
选择进入主输入或功率放大器上的输入信号 - 简单地说，
选择收听的音源。
RC-1550 立体声放大器
录音选择旋钮
只能从前面板操作
旋转前面板上的旋钮□ 选择进入录音输出的输入信号。如
果您没有录音，将旋钮围到OFF的位置。这可减少系统中
其它设备产生干扰的机会。
单独的录音和收听选择按钮可大大增加您使用 RC-1550
的灵活性。例如，选择录音选择器的 CD 和收听选择器的
Tuner，您可以在收听调谐器时将CD录制到磁带上。
如果您有可进行同步读写的三头录音机DA或T录音机，您
可以通过将LISTENING开关□设置到TAPE 1或TAPE 2的位
置监听录音。
注意：如果您用录音选择旋钮□选择TAPE 1，只有TAPE 2
录音输出上才会出现录音信号。要将磁带从一部磁带机录
制到另一部磁带机，将音源录音机连接到TAPE 1输入和输
出，并将录音选择旋钮转到Tape 1。将您正复制的磁带录
音机连接到Tape 2 输入和输出。

故障排除
音响系统的多数故障是由于错误连接或控制设置不正确引
致。如果您遇到问题，请屏蔽有问题的区域，检查控制器
设置，确定故障原因并进行必要的修正。如果RC-1550仍
然没有声音，请参考以下状况的建议：
待机指示灯不亮
RC-1550 连接到墙壁电源插座上时，待机指示灯应该点
亮。如果没有点亮，用其它电气设备例如台灯测试电源插
座。确保电源插座没有被已断开的开关控制。
更换保险丝
如果其它电气设备插到该插座时可正常工作，但RC-1550
插到同一插座且电源开关打开时电源指示灯和显示屏不
亮，表明内置保险丝可能已烧断。如果您确信发生这种情
况，请联络授权洛得经销商更换保险丝。
没有声音
检查信号源，看其是否正常工作。确保连接信号源和
RC-1550的输入的电缆已正确连接。确保监听选择开关已
被设置到正确的输入。检查功率放大器的电源和操作是否
正确。检查RC-1550与功率放大器之间的连接及功率放大
器与音箱之间的连接。
遥控器控制代码冲突
洛得的所有音频产品均使用相同的红外遥控器代码。在使
用多台洛得产品的系统中，一台产品的遥控器上的红外控
制代码可能与另一台产品的控制代码发生冲突。可以将RRAT94和RC-1550设置成替代的控制代码，避免发生这种冲
突。
要 变 更 R R - AT 9 4 的 红 外 代 码 ， 同 时 按 下 P h o n o 键 和 数
字 2 键。要改变 RC-1550 的红外代码，将 RR-AT94 对准
RC-1550 ，再按数字 2 键 5 秒钟。音量旋钮的 LED 灯会闪
烁，表示红外代码已经变更。
注意：按前述方式变遥控器和前置放大器的遥控器代码
后，遥控器不再可以操作洛得调谐器。要将 RR-AT94 的红
外代码恢复到默认设置，同时按PHONO键和数字1键。要
将RC-1550 的红外代码恢复到默认设计，将RR-AT94对准
RC-1550，再按往数字1键5秒钟。音量旋钮的LED灯会闪
烁，表示红外代码已经变更。
重设红外线代码
如果您需要重新设置红外代码，将 RR-AT64 遥控器对准
RC-1550，再按遥控器上的MUTE键○A 5秒钟以上。设备
将恢复默认设置，收听 CD 的 LED 指示灯□ 8 会变亮，表示
红外代码已经重设。如需要更多资料，请联络授权洛得经
销商。
