17、n music led them to manufacture high fi delity components 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 music lovers regardless of their budget, is shared by a

18、ll Rotel employees. The engineers work as a close team, listening to, and fi ne 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 fi nd capacitors from

19、 the United Kingdom and Germany, semi conductors from Japan or the United States, while toroidal power transformers are manu- factured in Rotels own factory. Rotels reputation for excellence has been earned through hundreds of good reviews and awards from the most respected reviewers in the industry

20、, who listen to music every day. Their comments keep the company true to its goal - the pursuit of equipment that is musical, reliable and affordable. All of us at Rotel, thank you for buying this product and hope it will bring you many hours of enjoyment. Getting Started Thank you for purchasing th

21、e Rotel RA-03 Stereo Integrated Amplifi er. When used in a high-quality music audio system, it will provide years of musical enjoyment. The RA-03 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

22、music. The RA-03 has a highly regulated power supply incorporat- ing a Rotel custom-designed toroidal power transformer. This low impedance power supply has ample power reserves, which enables the RA-03 to easily reproduce the most demand- ing audio signals. This type of design is more expensive to

23、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-03 circuitry uses metal fi lm resistors and polystyrene or polypropylene capaci

24、tors 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-03 are easy to install and use. If you have experience with other stereo systems, you shouldnt fi nd any- thing perplexing. Simply plug in the as

25、sociated components and enjoy. The RR-AT94 Remote Control Some functions can be done with either the front panel controls, or the supplied RR-AT94 remote control. When these operations are described, the call out number for both controls is shown. For example, you can adjust the volume with either t

26、he front panel Volume control 0 or the remote control buttons a. See the “IR Inputs and Output” section for more information on ways to expand the IR control capabilities of your system. Note: Remove the batteries from the re- mote control if it will not be used for a long period of time. Do not lea

27、ve run down bat- teries in the remote control. Exhausted bat- teries can leak corrosive chemicals which will damage the unit. NOTE: The RR-AT94 can be used to oper- ate the basic function of other certain other Rotel components, including Tuners, CD Players and DVD Players. To operate a Rotel Tuner

28、1) Select the tuner function of the RR-AT94. 2) Press “Power” and “1” (RT-02) or “2” (RT-940AX). 3) Press the key for Tuner operation. To operate a Rotel CD Player Select the CD function of the RR-AT94 To operate a Rotel DVD Player Select the AUX 1 function of the RR-AT94. Contents Important Safety

Do not cover or block the sensor. It must be unobstructed or the remote control will not work pr

33、operly. The operation of the Remote Sensor can also be affected if it is exposed to bright light, particu- larly sunlight. Certain types of lighting, such as halogen lights, that emit a fair amount of infrared light, can also interfere with proper operation. In addition remote control functions may

34、not work reliably if the batteries in the RR-AT94 are weak. A Few Precautions WARNING: To avoid potential damage to your system, turn off ALL the components in the system when connecting or discon- necting the loudspeakers or any associated components. Do not turn the system com- ponents back on unt

35、il 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 amplifi er. Please read this manual carefully. It provides information on how to incorporate the

36、 RA-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. Save the RA-03 shipping carton and all en- cl

37、osed packing material for future use. Shipping or moving the RA-03 in anything other than the original packing material may result in severe damage to your amplifi er. Fill out and send in the owners registration card packed with the RA-03. Also be sure to keep the original sales receipt. It is your

38、 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-03 can be affected by its environment. Avoid placing the RA-03 on top of other components. Also avoid routing audio sig

39、nal cables near power cords. This will minimize the chance it will pick up hum or interference. The RA-03 generates heat as part of its normal operation. The heat sinks and ventilation open- ings in the amplifi er are designed to dissipate this heat. The ventilation slots in the top cover must be op

40、en. There should be 10 cm (4 inches) of clearance around the chassis, and reason- able airfl ow through the installation location, to prevent the amplifi er from overheating. Remember the weight of the amplifi er when you select an installation location. Make sure that the shelf or cabinet can suppo

41、rt it. We recommend installing the RA-03 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 compon

42、ents. 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 qua

43、lity, shielded cables will also help to prevent noise or interference from degrad- ing 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. AC Power and Control AC Power Input o The RA-03 does not draw h

44、igh levels of current from the power outlet. However, whenever pos- sible, it 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) can handle the current demanded by the RA-03 an

45、d all the other components connected to it. Your RA-03 is confi gured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line confi guration is noted on a decal on the back p

46、anel. NOTE: Should you move your RA-03 amplifi er to another country, it is possible to reconfi gure it for use on a different line voltage. Do not attempt to perform this con- version yourself. Opening the enclosure of the RA-03 exposes you to dangerous volt- ages. Consult a qualifi ed service pers

47、on or the Rotel factory service department for information. 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 amplifi er (as well as other audio and video components) while you are away. Power Switch 2 and P

48、ower Indicator 1 Press the front panel Power Switch 2 button, to turn the RA-03 on. The Power Indicator light 1 is illuminated when the RA-03 is on. Press Power Switch button again to turn the RA-03 off. Once the RA-03 has been turned on with the front panel power switch, it can be switched between normal operating mode and standb
