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 WattsThis 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 StartedThank 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 PrecautionsWARNING: 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.PlacementLike 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.CablesBe 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 ControlSome 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 BatteriesTwo 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 ControlAC 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 1Press 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 rSee 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 ConnectionsNOTE: 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 uSee 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 pSee 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 ConnectionsMONO SUB Output iThere 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 oThe 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 5The 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 tothe speakers. Use the front panel 7 or remote control K A-B SpeakerSelector 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 3The RA-1592MKII has two sets of speaker outputs, labeled SPEAKER A and SPEAKER B. The speaker outputs are controlled by the A-B speaker selectorbuttons 7 on the front panel and the buttons K on the remote control.Speaker SelectionIf 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 SelectionUse 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 PhasingThe 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.

Network Connection =The RA-1592MKII can be attached to a network using the rear panelNETWORK socket =. The NETWORK configurations allow both STATICand DHCP IP addressing. See the Network section of this manual under Setting Menu for IP address configuration information.The NETWORK connection allows software updates to be downloaded from the Internet. The NETWORK connection also allows IP control for integration with automation systems.For additional information on the IP control please contact your authorized Rotel dealer.Protection CircuitThe 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.Settings MenuYou can access the settings menu from the front panel by pressing the MENU9 button or F on the remote.
