20、r 5 About Rotel A family whose passionate interest in music led them to manufacture high fidelity compo- nents of uncompromising quality founded Rotel over 40 years ago. Through the years that passion has remained undiminished and the family goal of providing exceptional value for audiophiles and mu

21、sic lovers regardless of their budget, is shared by all Rotel employees. The engineers work as a close team, listen- ing 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

22、best they can. You are likely to find ca- pacitors from the United Kingdom and Ger- many, semiconductors from Japan or the United States, while toroidal power transformers are manufactured in Rotels own factory. Rotels reputation for excellence has been earned through hundreds of good reviews and aw

23、ards from the most respected reviewers in the industry, who listen to music every day. Their comments keep the company true to its goal - the pursuit of equipment that is musi- cal, reliable and affordable. All of us at Rotel, thank you for buying this product and hope it will bring you many hours o

24、f enjoyment. Getting Started Thank you for purchasing the Rotel RB-03 Ste- reo Power Amplifier. When used in a high- quality music audio system, it will provide years of musical enjoyment. The RB-03 is a full featured, high performance component. All aspects of the design have been optimized to reta

25、in the full dynamic range and subtle nuances of your music. The RB-03 has a highly regulated power supply incorporat- ing a Rotel custom-designed toroidal power transformer. This low impedance power sup- ply has ample power reserves, which enables the RB-03 to easily reproduce the most de- manding a

26、udio signals. This type of design is more expensive to manufacture, but it is better for the music. English The printed circuit boards (PCB) are designed with Symmetrical Circuit Traces. This insures that the precise timing of the music is main- tained and faithfully recreated. The RB-03 cir- cuitry

27、 uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been ex- amined to ensure the most faithful music re- production. The main functions of the RB-03 are easy to install and use. If you have experience with other stereo sy

28、stems, you shouldnt find any- thing perplexing. Simply plug in the associ- ated 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 disconnect- ing the loudspeakers or any associated components. Do no

29、t turn the system compo- nents back on until you are sure all the con- nections 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. It pro

30、vides information on how to incorporate the RB-03 into your system as well as information that will help you get optimum sound performance. 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. Sa

31、ve the RB-03 shipping carton and all en- closed packing material for future use. Ship- ping or moving the RB-03 in anything other than the original packing material may result in severe damage to your amplifier. Fill out and send in the owners registration card packed with the RB-03. Also be sure to

32、 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.

35、that handle low- level signals, the RB-03 can be affected by its environment. Avoid placing the RB-03 on top of other components. Also avoid routing au- dio signal cables near power cords. This will minimize the chance it will pick up hum or in- terference. The RB-03 generates heat as part of its no

36、r- mal operation. The heat sinks and ventilation openings in the amplifier are designed to dis- sipate 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 lo- cation, to prev

37、ent 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 RB-03 in furniture designed to house audio components. Such furniture is designed to reduce or suppress v

38、ibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. Cables Be sure to keep the power cords, digital sig- nal cables and regular audio signal cables in your installation away from each ot

39、her. This will minimize the chance of the regular au- dio signal cables picking up noise or inter- ference 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

40、 questions see your authorized Rotel dealer for advice about the best cable to use with your system. RB-03 Stereo Power Amplifier AC Power and Control AC Power Input The RB-03 is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Do not use an extension cord. A heavy

41、duty multi-tap power outlet strip may be used, but only if it is rated to handle the current demand of the RB-03. Be sure the Power Switch on the front panel of the RB-03 is turned off. Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. Plug the other end

42、into an appropriate AC outlet. Your RB-03 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 115 volts/60 Hz , Europe: 230 volts/50 Hz). The AC line con- figuration is noted on a label on the back panel. NOTE: Should you move your RB-03 to another

43、 country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this con- version yourself. Opening the enclosure of the RB-03 exposes you to dangerous volt- ages. Consult a qualified technician or the Rotel factory service department for infor- ma

44、tion. If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier. Power Switch and Indicator The Power Switch is located on the front panel. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push

45、 the switch in. The LED indicator above the switch will light, indicating that the am- plifier is turned on. To turn the amplifier off, push the button again and return it to the out position. Trigger ON/OFF Mode Selector The Amplifier provides the option for manual or automatic power on/off operati

46、on. 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 automati- cally when a 12V trigger signal is present at the 3.5 mm Jack of TRIGGER IN on the rear panel. The amplifier will go into standby mode if the 1

47、2V 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 The jack labeled IN is for connecting

48、the 3.5mm Plug/Cable carrying a 12 V trigger signal to turn the amplifier on and off. To use this fea- ture the toggle switch must be set to the ON position. This input accepts any control sig- nal (AC or DC) ranging from 3 volts to 30 volts. The jack labeled OUT is for connecting an- other 3.5mm pl

49、ug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a 12 V trigger signal is applied to the IN connector. Input Signal Connection See Figure 2 for normal stereo wir- ing illustration. The RB-03 has conventional RCA type input connectors, the type fou
