About Rotel
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.

English
The RC-1580 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-1580 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-1580 has a superb phono preamp stage, derived from Rotel’s
finest phono preamplifier, the RHQ 10. The preamp stage can be
used with either a moving magnet (MM) or a moving coil (MC) phono
cartridge. This shows our commitment to phono sound quality and our
interest in the recreation of fine music.
The RC-1580 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-1580 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-1580 shipping carton and all enclosed packing material
for future use. Shipping or moving the RC-1580 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-1580. 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 RC-1580
can be affected by its environment. Do not stack the RC-1580 on top
of a power amplifier. This will minimize chance it will pick up hum
or interference. We recommend installing the RC-1580 in furniture
designed to house audio components. Such furniture is designed to
reduce or suppress vibration which can adversely affect sound quality.
Ask your authorized Rotel dealer for advice about component furniture
and proper installation of audio components.
Cables
Be sure to keep the power cords, digital signal cables and 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.
RR-AT97 Remote Control
The RC-1580 includes a full-function remote control that performs most
of the functions of the front panel controls. In addition it can operate
many of the controls on other Rotel components. See the “Controlling
Other Components” section of this manual for more information.
Most of the RR-AT97 functions duplicate the front panel controls. In this
manual the remote control functions are covered in the same section
as the front panel control operation. Numbers in boxes such as 1
indicate items on the front and rear panel control and connection
illustrations. See Figure 1 on page 3. Letters in circles such as A
indicate items on the RR-AT97 illustration. See Figure 2 on page 3.
Remote Sensor 5
The Remote Sensor picks up the infrared signals from the remote
control. Do not cover or block the sensor. It must be clear of
obstructions or the remote control will not work properly. The operation
of the Remote Sensor can also be affected if it is exposed to bright
light, particularly sunlight. In addition remote control functions may not
work reliably if the batteries in the RR-AT97 are weak.
AC Power and Control
AC Power Input p
Note: Be sure to set the Volume control to the minimum (full
counterclockwise) position before connecting the power cord.
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.
It is usually best to plug the RC-1580 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.
Your RC-1580 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.
Note: Should you move your RC-1580 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-1580 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 1
RemoteOFF/ONSwitchA
STANDBY Indicator
The STANDBY switch and STANDBY indicator 1is located on the
left side of the front panel. To use the RC-1580, 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 and Recording input buttons 89 will light.
When the STANDBY switch is pushed in, you can turn the RC-1580
on, or put it in Standby mode, with the ON and OFF buttons Aof the
RR-AT97 remote control.
If you will not be using the RC-1580 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
(except ring around the Standby switch).
Note: Be sure to set the Volume control to the minimum (full
counterclockwise) position before you push in the STANDBY switch.
Input Signal Connections wand e
[See Figure 3.]
The RC-1580 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 e
The CD, Tuner, and Aux inputs of the RC-1580 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-1580. Ask your authorized Rotel dealer for advice about cables.
Phono Input Selector Switch =
The Phono input is for a moving magnet (MM) or moving coil (MC)
phono cartridge only and is incompatible with line level components.
Set the Phono Input Selector Switch as appropriate for the phono
cartridge you are using. Leave the switch button in the out position
for a moving magnet cartridge; push the switch in for a moving coil
cartridge.
Some high output moving coil cartridges are designed to operate
in the moving magnet position. If you are in doubt about the correct
setting, check the instruction manual for your phono cartridge for
information regarding its output voltage and the expected input
impedance. The Phono input has 47 kOhms input impedance and 2.5
mV sensitivity in the MM position and 100 Ohms input impedance
and 0.25 mV sensitivity in the MC position. If you still have questions
about the proper setting of the phono input selector switch, consult
your authorized Rotel dealer.
Phono Input wand Ground Connection q
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 r
Tape 1 input/outputs and Tape 2 outputs can be connected to any
playback/record device, Tape 2 inputs are reserved for Theater
Bypass Mode, refer to bypass section.
When connecting a recorder to the RC-1580, remember that the
outputs of the recorder must be connected to the tape inputs of the
RC-1580. Similarly the tape outputs of the RC-1580 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y
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-1580 to the correct
channels of the amplifier.
Note: There are two sets of RCA outputs on the RC-1580. 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.

English
IROutputi
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 o
Many Rotel amplifiers offer the option of turning them on and off using
a 12 volt trigger signal sent to them. The RC-1580 provides two 12
volt trigger outputs. When the RC-1580 is turned on, a 12 volt DC
signal is sent to the amplifiers to turn them on. When the RC-1580
is put in STANDBY mode, the trigger signal is interrupted and the
amplifiers turn off.
To use the remote turn on feature, connect one of the RC-1580 12V
TRIGGER OUT jacks 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.
Note: The number “1” 12V trigger signal is turned off when
headphones are plugged into the front panel headphone outlet. See
the Phones Output section.
ComputerI/OConnectort
The RC-1580 can be operated from a personal computer running
audio system control software from third-party developers. This control
is accomplished by sending the operating codes normally sent by the
RR-AT97 remote control over a hard-wired network connection from the
computer.
The COMPUTER I/O input provides the necessary connection on the
back panel. It accepts standard RJ-45 8-pin modular plugs, such as
those commonly used in 10-BaseT UTP Ethernet cabling.
For additional information on the connections, software, and operating
codes for computer control of the RC-1580, contact your authorized
Rotel dealer.
Theater By-pass Mode
BYPASS indicator 2
The input marked Tape 2 rhas been set to provide a by-pass mode
for users requiring a unity gain stage through which they can use their
surround sound processor. This input will only function in a by-pass
mode so do not connect a tape recording unit to this input.
To use the By-pass mode, plug the front channel output of the surround
sound processor into the Tape 2 inputs. When the Tape 2 input B8
is selected, the signal from the processor is sent directly through the
preamplifier and by-passes the tone and volume functions. Once made
a by-pass mode, the BYPASSindicator of front panel is turned on.
Setting a system up this way provides a way to integrate a stereo
amplifier to be used as the front channels of a surround sound system.
Only the Tape 2 input can provide the by-pass function. It requires
no additional setup, making it easy to switch between normal stereo
mode and surround sound mode by using the input selector.
Note: Rotel uses the same operating IR codes for all its audio
products. That means that in a situation where the operator will use a
remote control then it is recommended that the codes for the RR-AT97
and the RC-1580 be changed.
To change the IR code of the RR-AT97, press the Phono button and
the 2 button at the same time.
To change the IR code of the RC-1580, point the RR-AT97 at the
RC-1580 and press and hold the 2 button for 5 seconds. The LED in
the volume control will flash to indicate the IR code has changed.
It’s is probably easiest to choose a third party learning remote
control and teach the new source selection codes and those of the
surround sound processor in to it. Alternatively you can use the two
remote controls to operate the different systems.
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-AT97 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-1580 to the default setting, point
the RR-AT97 at the RC-1580 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.
IRInputsandOutputs
External Remote Input u
This 3.5 mm mini-jack (labeled EXT REM IN) receives command codes
from an industry-standard infrared receivers (Xantech, etc.) 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

10 RC-1580 Stereo Control Amplifier
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. The power amplifier will continue to receive a signal and
the speakers will continue to play. However, when headphones are
plugged in, the 12V turn-on signal from the number “1” 12V Trigger
Output is cut off. (The number “2” 12V Trigger output remains on.)
So if your system is configured to use the number “1” 12V Trigger
Output to turn the amplifier on and off, plugging in headphones will
automatically turn off the power amplifier.
Media Player Input -
A 3.5mm (1/8”) stereo input socket for a “Media Player” is provided
on the front of the RC-1580 and is selected by pressing the AUX 3
Listening input buttons.
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-1580
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 AUX3 is disconnected. Removing the
3.5mm plug from the Media player socket will allow the rear AUX3
input to function.
Audio Controls
Volume Controls 7and C
The front panel Volume control 7increases 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-AT97
remote use the Volume + and – buttons Cto increase or decrease the
volume level.
Mute Button E
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 Buttons 8B
Press one of the Listening Selector Buttons to select the input signals
that goes to the main outputs and to the power amplifier – or, more
simply, which source is heard.
Recording Selector Buttons 9D
Press one of the Recording Selector Buttons to select the input signal that
goes to the record outputs. When you are not recording, press the Off
button. 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-1580. 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 your
recording by pressing the TAPE 1 LISTENING button.
Note: The TAPE 2 input is a dedicated Theater By-Pass input. See
the information in the Theater Bypass Mode section on the preceding
page.

ControllingOtherComponents
In addition to operating many of the controls of the RC-1580, the
RR-AT97 remote control can operate basic features of some Rotel CD
players, DVD players, and AM/FM tuners.
CD Functions
The /PLAY, .STOP, ,PAUSE, {}TRACK and, RANDOM
buttons, and NUMERIC buttons (0 - +10) operate many Rotel CD
players after the CD Listening button on the remote has been pressed.
DVD Functions
The /PLAY, .STOP, ,PAUSE, {}TRACK and RANDOM buttons
operate Rotel DVD players, after the AUX1 Listening button on the

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-1580, refer to the suggestions for the
following conditions:
Standby Power Indicator Is Not Lit
The Standby Power Indicator should be lit whenever the RC-1580 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-1580 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-1580 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-1580 and the power amplifier, and the power
amplifier and speakers.
Resetting the IR Code
If you reset the RC-1580 IR code to use the Bypass function, you can
reset it to the default code using the procedure described in the Note
in the Bypass Function section of this manual. Or you can use the
front panel buttons. While RC-1580 is turned on, press and hold the
Recording Off button 9for 5 seconds. The LED for the Listening CD
button 8will turn On to indicate the IR code is reset. If the Bypass
LED is lit it will turn Off.

标记为Tape 2的输入□已经设置到为需要统一增益级的用
户提供直通模式，以便使用环绕声处理器。本输入只在直
通模式中工作，因此，不要将磁带录音机连接到本输入。
要使用直通模式，将环绕声处理器前面板输入连接到Tape
（磁带） 2输入。选择Tape 2输入 ○○后，来自处理器的
信号被直接传送到前置放大器，并直通了音调和声量控制
功能。选择直通模式后，前面板上的直通指示灯变亮。
以这种方式设置系统可将立体声放大器用于环绕声音响
系统的前置声道。只有Tape （磁带）2输入才提供直通功
能。它不需要进行额外的设置，让使用输入选择开关在普
通立体声模式和环绕声模式之间切换更为方便。
注意：洛得的所有音频产品均使用相同的红外操作代码。
这表示在用户使用遥控器的情况下，建议改变RR-AT97和
RC-1580的代码。
要变更RR-AT97的红外代码，同时按下Phono（唱机）键和
数字2键。
要改变RC-1580的红外代码，将RR-AT97对准RC-1580，
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。
选择第三方学习型摇控器，并学习新的音源选择代码和环
绕声处理器代码，可能更为简单。作为替代，您可以使用
两个遥控器分别操作不同的系统。
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-AT97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-1580 的红外代码恢复到默认设计，将RR-AT97对准
RC-1580，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。
红外输入和输出
外置遥控输入
本3.5mm小型插头（标为EXT REM IN（外置遥控输入））
接收位于主听音室中的工业标准红外线接收器（Xantech
等）发送的命令代码。本装置安装在机柜中且前面板上的
感应装器被遮挡时，本功能非常有用。请咨询授权洛得经
销商寻求有关外部接收器的资料和正确连接插头到小型插
座的方法。
注意：来自EXTERNAL REMOTE IN插座的红外信号可传给
使用外部红外线发射器或硬线连接的IR OUT插座的音源设
备。
红外输出
IR OUT （红外输出）1和2插孔将在EXTERNAL REM IN
（外接遥控器输入）插孔接收到的红外信号发送到放置在
源设备前面的红外发射器上，或发送到具备兼容后面板红
外输入接口的其它洛得设备上。
这个输出接口用于在源设备上的感应器被柜体遮挡时传输
遥控器发出的红外信号。
有关红外线复制系统的资料，请咨询授权洛得经销商。
注意：位于这些插孔旁边的EXT REM IN插孔用于同复制前
面板红外线感应器的外部红外线感应器一同使用，并位于
主要区域。
12V触发信号连接
许多洛得放大器提供了使用向它们发出的12V触发信号
开关机的选择。RC-1580提供了两组12V触发信号输出接
口。RC-1580被打开时，会向后级放大器发出12V直流信
号打开放大器。RC-1580被置于待机模式中时，触发信号
被截断，放大器被关闭。
要使用遥控开机功能，使用两端装有3.5mm小型小型插头
的电缆将RC-1580的12V触发信号输出插孔连接到洛得后
级放大器的12V触发信号输入插孔。+12V直流信号在“顶
端”接头上出现。
注意：将耳机插到前面板耳机输出插孔中时，第1个12V
触发信号被关闭。请参阅“耳机输入”一节。
Computer I/O
（计算机输入/输出）接口
RC-1580可以用带第三方音频系统控制软件的个人计算机
进行操作。通过从计算机网络电缆连接发送由RR-AT97遥
控器发送的操作代码来实现这种控制。
后面板上有的COMPUTER I/O（计算机输入/输出）输入
提供了所需的网络连接。它使用标准的RJ-45 8针插头，例
如通常用于10-BaseT UTP以太网线上的插头。
