18、rdless of their budget, is shared by all 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. Y

19、ou are likely to fi nd capacitors from the United Kingdom and Germany, semi- conductors from Japan or the United States, and toroidal power transformers manufactured in Rotels own factory. Rotels reputation for excellence has been earned through hundreds of good reviews and awards from the most resp

20、ected review- ers in the industry, 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 Start

21、ed Thank you for purchasing the Rotel RC-1082 Stereo Control Amplifi er. When used in a high-quality music audio system, it will provide years of musical enjoyment. The RC-1082 is a full featured, high perfor- mance preamplifi er. All aspects of the design have been optimized to retain the full dyna

22、mic range and subtle nuances of your music. The RC-1082 has a highly regulated power sup- ply 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 RC-1082 to easily reproduce

23、 the most demanding audio signals. This type of design is more expensive to manufacture, but it is better for the music.

27、t 9 No Sound 9 Specifi cations .9 The RC-1082 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 RC-1082 circuitry uses metal fi lm resistors and polystyrene or polypropylene capacit

28、ors in important signal paths. All aspects of this design have been examined with the fi nal goal being faithful reproduction of music. The RC-1082 has a superb phono preamp stage, derived from Rotels fi nest phono pream- plifi er, the RHQ 10. The preamp stage can be used with either a moving magnet

29、 (MM) or a moving coil (MC) phono cartridge. This shows our commitment to phono sound quality and our interest in the recreation of fi ne music. The RC-1082 is straightforward in its instal- lation and operation. If you have experience with other stereo systems, you shouldnt fi nd anything perplexin

30、g. Simply plug in the as- sociated components and enjoy. A Few Precautions Please read this manual carefully. It provides complete information on how to incorporate the RC-1082 into your system as well as general information that will help you get optimum sound performance. Please contact your autho

31、rized 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-1082 shipping carton and all enclosed packing material for future use. Ship- ping or moving the RC-1082 in anything other than the original packing materia

32、l may result in severe damage to your amplifi er. Fill out and send in the owners registration card packed with the RC-1082. 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. 6 RC-1082

33、Stereo Control Amplifi er Placement Like all audio components that handle low-level signals, the RC-1082 can be affected by its environment. Do not stack the RC-1082 on top of a power amplifi er. This will minimize chance it will pick up hum or interference. We recommend installing the RC-1082 in fu

34、rniture 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. Cables Be sure to keep the power cords,

35、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 preven

36、t 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 RR-AT97 Remote Control The RC-1082 includes a full-function remote control that performs most of the functions

37、 of the front panel controls. In addition it can operate many of the controls on other Rotel components. See the “Controlling Other Components” section of this manual for more information. Most of the RR-AT97 functions duplicate the front panel controls. In this manual the remote control functions a

38、re covered in the same section as the front panel control operation. Numbers in gray boxes such as 1 indicate items on the front and rear panel control and connection illustrations. See Figure 1 on page 3. Letters in gray circles such as A indicate items on the RR-AT97 illustration. See Figure 2 on

39、page 3. Remote Sensor 3 The Remote Sensor is located to the right of the Phones jack on the front panel. It picks up the infrared signals from the remote control. Do not cover or block the sensor. It must be clear of obstructions or the remote control will not work properly. The operation of the Rem

40、ote Sensor can also be affected if it is exposed to bright light, particularly sun light. In addition remote control functions may not work reliably if the batteries in the RR-AT97 are weak. AC Power and Control AC Power Input NOTE: The RC-1082 will be turned on and in the normal operating mode as s

41、oon as it is connected to the AC outlet. Be sure to set the Volume control to the minimum (full counterclockwise) position before connect- ing the power cord. Connect the supplied power cord to the AC Input receptacle on the rear panel. Do not connect the power cord to the power outlet until all the

42、 audio input and output connections have been made. It is usually best to plug the RC-1082 directly into a 2-pin polarized wall outlet. Avoid the use of extension cords. 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 c

43、omponents connected to it. Your RC-1082 is confi gured 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 confi guration is noted on a decal on the rear panel. NOTE: Sho

44、uld you move your RC-1082 amplifier to another country, it is possible to reconfigure your amplifier for use on a dif- ferent line voltage. Do not attempt to per- form this conversion yourself. Opening the enclosure of the RC-1082 exposes you to dangerous voltages. Consult a qualified ser- vice pers

45、on or the Rotel factory service de- partment 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. STANDBY Switch 1 R

46、emote OFF/ON Switch A STANDBY Indicator 2 The STANDBY switch 1 is located on the left side of the front panel. When the RC-1082 is fi rst plugged into a power outlet it will be in “operation” mode and the Standby indicator 2 will be lit. In addition the indicators above the selected Listening and Re

47、cording input buttons 90 will light. Press the front panel Standby switch again, or the “Off” button on the remote, to return the RC-1082 to “standby” mode. NOTE: The RC-1082 will be turned on and in the normal operating mode as soon as it is connected to the AC outlet. Be sure to set the Volume con

48、trol to the minimum (full counterclockwise) position before connect- ing the power cord. Input Signal Connections e and r See Figure 3. The RC-1082 has conventional RCA-type connectors for all inputs. NOTE: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system i
