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 it is especially important for a manufacturer to do all
it can to engineer products that have a minimum impact on the environment.
At Rotel, we are proud to do our part. We have reduced the lead content
in our products by using special lead-free ROHS solder and components.
Our engineers continually strive to improve power supply efciency without
compromise to quality. When in standby mode Rotel products use minimal
power to meet global Standby Power Consumption requirements.
The Rotel factory is also doing their part to help the environment through
constant improvements to product assembly methods for a cleaner and
greener manufacturing processes.
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 amplier’s power output is rated as 200 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.

10 RA‑1592 Stereo Integrated Amplier
Getting Started
Thank you for purchasing the Rotel RA-1592 Stereo Integrated Amplier.
When used in a high-quality music audio system, your Rotel product will
provide years of musical enjoyment.
The RA-1592 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-1592 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-1592 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-1592 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-1592 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-1592
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-1592 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-1592 can
be affected by its environment. Avoid placing the RA-1592 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-1592 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-1592 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-1592 is supplied with an RR-AX150 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‑AX150 Remote Control
Some functions can be done with either the front panel controls, or the
supplied RR-AX150 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 Jand 2 Lat the same time to set
the remote control to send Audio Code 2.
2.Point the remote at the unit and press 2 Lbutton for 8 seconds. The unit
will show “Audio Custom Code 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 HILN
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 AA 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-AX150. 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-1592
consistently. Installing fresh batteries should eliminate the problem.

AC Power and Control
AC Power Input [
Your RA-1592 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‑1592 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‑1592 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-1592 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-1592 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
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-1592. In Standby mode the
power LED remains lit, but the display is turned off.
NOTE: Place the self adhesive ring over the light surrounding the Power
switch if the blue light is too bright.
12V TRIGGER Connection r
Some audio components can be turned on automatically when they receive
a 12V turn on signal. The two 12V Trigger Outputs of the RA-1592 provide
the required signal. Connect compatible components to the RA-1592 with
a conventional 3.5mm mini plug cable. When the RA-1592 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 trigger’s power
on or off features will override the Rotel Link features.
Input Signal Connections -up
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 uand 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 u
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-1592. Ask your authorized
Rotel dealer for advice about cables.
Balanced (XLR) Inputs p
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.
NOTE: You should choose only one method of analog connection from
a source component to RA‑1592. Do not connect both the RCA and
XLR outputs of a source component to the RA‑1592 at the same time.
Digital Signal Inputs -
See Figure 4
There are three sets of digital inputs labeled 1, 2 and 3, 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-1592. The unit is capable of decoding PCM signals
up to 24 bit, 192kHz.
Output Connections
MONO SUB Output i
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-1592.
Preamp Output o
The RA-1592 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.

12 RA‑1592 Stereo Integrated Amplier
Speaker Outputs ]
See Figure 3
The RA-1592 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 Kon 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-1592.
See your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1592 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 ]
Turn off all the components in the system before connecting the speakers.
The RA-1592 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-1592 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 7or remote control KA-B Speaker
Selector to turn off the speakers.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.
Remote Sensor 2
This remote sensor window receives IR commands from the remote control.
Please do not block this sensor.
Display 3
The front panel display shows the source selected, volume level and tone
settings. The display provides access to the setup and conguration menu
options of the amplier.

Protection Circuit
The amplier has both thermal and over-current protection circuitry that
protects the amplier 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
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

Sense source is configured as COAX 1 and the unit is listening to OPT
2, the signal sense functions will not be activated.
NOTE: When the RA‑1592 enters standby mode via the remote
control, the Signal Sense function will not operate until the unit detects
the audio has stopped for the minimum 10 minute time‑out period. This
prevents the unit from immediately powering back on if there is still

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-1592, 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-1592 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-1592 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-1592 inputs are connected properly.
Check the wiring between the RA-1592 and the speakers.
Cannot Connect via Bluetooth
If you cannot pair your Bluetooth enabled device to the RA-1592, delete the
memory of the previous connection on your device. On your device this is
often listed as “Forget this Device”. Then try to make the connection again.
