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 The RB-1590 power output is quoted as 350 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. The highly regulated power supplies of the Rotel amplifiers ensures that they will produce the full specified power output to one or both channels. About Rotel 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 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 the Rotel design is optimized for use with all channels operating together, Rotel is able to specify the true power output for both channels. This can be important for your enjoyment, too. When watching movies, it s nice to have the amplifier able to reproduce full power into all the channels at the same time, especially in the case of a volcano exploding! Getting Started Thank you for purchasing the Rotel RB-1590 Stereo Power Amplifier. When used in a high-quality music or home theater system, your Rotel product will provide years of musical enjoyment.

8 8 RB-1590 Stereo Power Amplifier The RB-1590 is a high-power, two channel power amplifier, providing the highest level of audio performance. A massive power supply, premium components, and Rotel s Balanced Design ensure superb sound quality. High current capability allows the RB-1590 to drive the most demanding loudspeakers. Be aware that the RB-1590 is capable of high power levels, in excess of 350 watts respectively per channel. Make sure that your speakers can handle the power of the amplifier. If in doubt about your speakers, ask your local Rotel audio dealer for advice. This amplifier is straightforward in its installation and operation. If you have experience with other stereo power amplifiers, 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 RB-1590 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 RB-1590 shipping carton and all enclosed packing material for future use. Shipping or moving the RB-1590 in anything other than the original packing material may result in severe damage that is not covered by the warranty. If included in the box please fill 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 required. Placement The RB-1590 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 unit 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. AC Power and Control AC Power Input 6 Your amplifier is configured at the factory for the proper AC voltage in the country where you purchased it, either 120 volts or 230 volts. The AC line configuration is noted on a decal on the back panel. NOTE: Should you move your amplifier to another country, it may be possible to reconfigure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the amplifier 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 high power rating, the amplifier can draw considerable current. Therefore, it should be plugged directly into a wall outlet. The RB-1590 must be plugged into a 3-pin polarized 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 amplifier and all the other components connected to it. Be sure the POWER SWITCH 1 on the front panel of the amplifier is turned off (in the out position). Then, connect the supplied power cord to the Power Connector 6 on the rear panel of the unit and the AC power outlet. 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 RB (as well as other audio and video components) while you are away. Power Switch and Power Indicator 1 The power switch is located on the left side of the front panel. To turn the amplifier on, push the switch in. The ring around the switch will light up, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position. NOTE: Place the self adhesive ring over the light surrounding the power switch if the blue light is too bright. Trigger On/Off Mode Selector 7 The amplifier provides the option for manual or automatic power on/off operation. These modes are selectable using a toggle switch on the back panel. With the switch in the +12V TRIGGER ON position, the amplifier is turned on automatically when a 12V trigger signal is present at the 3.5 mm connector of TRIGGER IN on the rear panel. The amplifier will go into standby mode if the +12V signal is not present. The front panel POWER SWITCH overrides this function. It must be ON for the +12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. 12V Trigger Input and Output 7 The connector labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trigger signal to turn the amplifier on and off. To use this feature the 12V trigger toggle switch must be set to the ON position. This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts.

9 9 The connector labeled OUT is for connecting another 3.5mm plug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a +12 volt trigger signal is applied to the IN connector. Protection Circuitry 1 The RB-1590 features thermal and over-current protection circuits that protect against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, these protection circuits are independent of the audio signal and have no impact on sonic performance. Instead, the protection circuits monitors the temperature of the output devices and the current they are handling and shuts down the amplifier if operating conditions 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 the Power Indicator on the front panel will blink. If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the Power Indicator should light up, indicating that the amplifier is turned on normal. 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. Input Signal Connections 234 See figure 2 and 3 NOTE: To prevent loud, potentially damaging noises, make sure the amplifier is turned off when you make any changes to the input signal configuration. The RB-1590 has conventional RCA type input connectors, the type found on nearly all audio equipment, as well as Balanced (XLR) input connectors. Select high quality audio interconnect cables. Connect each of the outputs from the preamplifier or signal processor to the corresponding input of the amplifier. Input Selector Switch 4 A toggle switch in the rear panel selects the type of input signal to use. Select the correct inputs to use with this flip switch. NOTE: You should choose only one method of analog connection from a source component to the amplifier. Do not connect both the RCA and XLR outputs of a source component to the same amplifier at the same time. Speakers Connection 5 Speaker Selection We recommend using loudspeakers with a nominal impedance of 4 ohms or higher with the RB You should exercise some caution in driving multiple pairs of speakers in parallel configuration, because the effective impedance the amplifier sees is cut in half. For example, when driving two pair of 8 ohm speakers, the amplifier sees a 4 ohm load. When driving multiple speakers in parallel, it is recommended that you select speakers with a nominal impedance of 8 ohms or higher. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RB See your authorized Rotel dealer if you have any questions. Speaker Wire Selection Use insulated two-conductor stranded wire to connect the RB-1590 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 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 Connection 5 NOTE: The following text describes both binding post and plug-in connections. DO NOT use both connection methods in combination to connect multiple speakers. Turn off all the components in the system before connecting the speakers. The RB-1590 has four pairs of color coded binding posts, two for each channel. These connectors accept bare wire, connector lugs, or dual banana type connectors (except in the European Community countries where their use is not permitted). Route the wires from the RB-1590 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 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.

10 10 RB-1590 Stereo Power Amplifier NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connectors. Troubleshooting Most difficulties in audio systems are the result of poor or wrong 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 RB-1590, refer to the suggestions for the following conditions: Power Indicator Is Not Illuminated No main power to the amplifier. Check the front panel power switch. Make sure that it is set to the on position. Check AC power connections at the amplifier and the AC outlet. Fuse Replacement If another electrical device works when plugged into the power outlet, but the Power Indicator still will not light when the unit 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 If the amplifier is getting AC power, but is producing no sound, check the PROTECTION INDICATOR on the front panel. If it is blinking, see below. If not, check all of your connections and control settings on associated components. Protection Indicator The front panel POWER indicator is blinking when the amplifier protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amplifier to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself.
