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 amplier. Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RC-1590 system congurations 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 RC-1590 shipping carton and all enclosed packing material for future use. Shipping or moving the RC-1590 in anything other than the original packing material may result in severe damage to your amplier.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 RC-1590 can be affected by its environment. Avoid placing the RC-1590 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 RC-1590 is supplied with an RR-AX100 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 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. The RR‑AX100 Remote Control Some functions can be done with either the front panel controls, or the supplied RR-AX100 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 Amplifier Remote Code The factory setting is remote code 1. If you nd that the remote is conicting with other Rotel ampliers, you can change to remote code 2 with the following steps.

1. From the remote control press Tuner L and 2 M at the same time to set

the remote control to send Audio Code 2.2. Point the remote at the unit and press 2 M key for 8 seconds. The unit will show “Audio Custom Code 1 -> 2”.3. Repeat the above procedure and press “1” key 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 IKMN can be used to operate CD or Tuner functions in your system. For the remote control to operate properly, make sure both the remote control and the CD or Tuner are both in same remote code. For more information please contact your authorized Rotel dealer. 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-AX100. 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 RC-1590 consistently. Installing fresh batteries should eliminate the problem. AC Power and Control AC Power Input

Your RC-1590 is congured 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 conguration is noted on a decal on the back panel. NOTE: Should you move your unit to another country, it may be possible to recongure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the unit exposes you to dangerous voltages. Consult a qualied 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. The RC-1590 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 RC-1590 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 the RC-1590 (as well as other audio and video components) while you are away. POWER Switch and Power Indicator

Press the front panel Power Switch button to turn the unit on. The Power Indicator light is illuminated when the unit is on. Press the 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 RC-1590. In Standby mode the power LED remains illuminated, 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.12 RC‑1590 Stereo Control Amplier 12V TRIGGER Connection

Some audio components can be turned on automatically when they receive a 12V turn on “signal”. The two12V Trigger Outputs on the RC-1590 provide the required signal. Connect compatible components to the RC-1590 with a conventional 3.5mm mini mono plug cable. When the RC-1590 is in standby mode, the trigger signal is disabled, so the components controlled by it will be turned off. NOTE: Do not connect both the Rotel Link and 12V trigger cables at the same time. The 12V trigger’s power on or off features will override the Rotel Link features. Input Signal Connections See Figure 3 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

and Ground Connection (GND)

See Figure 3Plug 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. This will help prevent hum and noise. Line Level Inputs

See Figure 3The CD, Tuner, and Aux inputs of the amplier 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 RC-1590. Ask your authorized Rotel dealer for advice about cables. Balanced (XLR) Inputs

See Figure 4A 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 RC-1590. Do not connect both the RCA and XLR outputs of a source component to the RC-1590 at the same time. Digital Inputs

See Figure 5There 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 RC-1590. The unit is capable of decoding PCM signals up to 24 bit, 192kHz. Output Connections Digital output

If you are using an outboard D/A converter or other digital processor, you will need an unprocessed digital data stream from the RC-1590. Using a standard 75 ohm coax/optical digital cable, connect the RC-1590’s digital output to the digital input connector on the outboard D/A converter. Line Output

The line output connectors can be used to send the analog audio to a separate processor device. These outputs bypass the volume encoder and are full line level output. They should be connected to the analog inputs of the processor. 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. MONO SUB Output

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 RC-1590. Preamp Output

See Figure 3The RC-1590 RCA-type output connectors are compatible with most power ampliers. As always, select high quality audio interconnect cables. Connect the left and right channel outputs of the RC-1590 to the corresponding inputs on the amplier or other component. NOTE: There are two sets of RCA outputs on the RC-1590. The second set of outputs may be used in custom system congurations to drive a second power amplier or to supply a signal to a special signal processor. Balanced (XLR) Preamp Output

See Figure 4Two pairs of XLR balanced connectors supply an analog output signal from the RC-1590 to a power amplier with XLR balanced input connectors. NOTE: Do not connect both the RCA and XLR to the same amplier at the same time. Headphone Output

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 preamp outputs. In most instances you should turn off the power amplier when listening to headphones.13 English NOTE: Because the sensitivity of speakers and headphones can vary widely, always reduce the volume level before connecting or disconnecting headphones.
