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.
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 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 efficiency 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 amplifier’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 amplifier’s 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 loudspeaker’s 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.

RA1592MKII Stereo Integrated Amplifier
Getting Started
Thank you for purchasing the Rotel RA-1592MKII Stereo Integrated Amplifier.
When used in a high-quality music audio system, your Rotel product will
provide years of musical enjoyment.
The RA-1592MKII 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-1592MKII 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-1592MKII 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-1592MKII 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-1592MKII are easy to install and use. 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
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 amplifier.
Please read this manual carefully. In addition to basic installation and
operating instructions, it provides valuable information on various RA-1592
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 shipping carton and all enclosed packing material for future use.
Shipping or moving the RA-1592MKII in anything other than the original packing
material may result in severe damage to your amplifier.
If included in the box please complete the owner’s registration card or
register on line. 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-1592MKII can
be affected by its environment. Avoid placing the RA-1592MKII 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-1592MKII 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-1592MKII 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-1592MKII 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 RRAX150 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.
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-1592MKII
consistently. Installing fresh batteries should eliminate the problem.
AC Power and Control
AC Power Input [
Your RA-1592MKII 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 back panel.
NOTE: Should you move your RA1592MKII 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 RA1592MKII
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.
Because of its relatively high power rating, the RA-1592MKII can draw
considerable current. Therefore, it should be plugged directly into a 2-pin
11
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-1592MKII 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 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-1592MKII. 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
See Figure 4 Some audio components can be turned on automatically when they
receive a 12V turn on signal. The two 12V Trigger Outputs of the RA-1592MKII
provide the required signal. Connect compatible components to the RA-1592MKII
with a conventional 3.5mm mini plug cable. When the RA-1592MKII is in turn off
mode, the trigger signal is interrupted, so the components controlled by it
are turned off.
Input Signal Connections
NOTE: To prevent loud noises that neither you nor your speakers will
appreciate, make sure the system is turned off when you make any signal
connections.
Phono Input u 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 u
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-1592MKII. 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 RA1592MKII. Do not connect both the RCA and XLR outputs of a
source component to the RA1592MKII 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-1592MKII. 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-1592MKII.
Preamp Output o
The RA-1592MKII 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 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 Output.
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 7 or remote control K A-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.
Speaker Outputs ] See Figure 3
The RA-1592MKII 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 K on the remote control.
Speaker Selection
If only one set of speakers will be used at any given time, the speakers may
have an impedance as low as 4 ohms. If there are times when both the A and B
speakers will be used, all the speakers should have an impedance of 8 ohms or
more. Speaker impedance ratings are less than precise. In practice, very few
loudspeakers will present any problems for the RA-1592MKII. See your
authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1592MKII to the
speakers. The size and quality of the wire can have an audible effect
12
RA1592MKII Stereo Integrated Amplifier
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 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 ] Turn off all the components in the system before
connecting the speakers. The RA-1592MKII 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-1592MKII 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.

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-
1592MKII, 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-1592MKII 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-1592MKII 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-1592MKII inputs are connected
properly. Check the wiring between the RA-1592MKII and the speakers.
