Through the years

18、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. The engineers work as a close team, listen- ing to, and fine tuning each new product until it reaches their exactin

19、g 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 ca- pacitors from the United Kingdom and Ger- many, semi conductors from Japan or the United States, while toroidal power transform- ers are manufactu

20、red 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, who listen to music every day. Their comments keep the company true to its goal - the pursuit of equipment that is musi- cal, rel

21、iable 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 the Rotel RA-1062 Stereo Integrated Amplifier. When used in a high-quality music audio system, it will pro- vide years of musical e

22、njoyment. The RA-1062 is a full featured, high perfor- mance component. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The RA-1062 has a highly regulated power sup- ply incorporating a Rotel custom-designed toroidal power transformer

23、and custom-made slit foil capacitors. This low impedance power supply has ample power reserves, which en- ables the RA-1062 to easily reproduce the most demanding audio signals. This type of design is more expensive to manufacture, but it is better for the music. The printed circuit boards are desig

24、ned with Symmetrical Circuit Traces. This insures that the precise timing of the music is maintained and faithfully recreated. The RA-1062 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been examined to ensur

25、e the most faithful music reproduction. In addition the RA-1062 has independent input signal selectors for listening and recording. They allow you to listen to one signal source while recording another. The main functions of the RA-1062 are easy to install and use. If you have experience with other

26、stereo systems, you shouldnt find any- thing perplexing. Simply plug in the associ- ated components and enjoy. Unpacking Carefully remove the RA-1062, the remote control, and accessories from the shipping carton. Save the shipping carton and all en- closed packing material for future use. Ship- ping

27、 or moving the unit in anything other than the original packing material may result in severe damage. 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 l

28、ow- level signals, the RA-1062 can be affected by its environment. Avoid placing the RA-1062 on top of other components. Also avoid rout- ing audio signal cables near power cords. This will minimize the chance it will pick up hum or interference. The RA-1062 generates heat as part of its normal oper

29、ation. The heat sinks and venti- lation 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 ampli

30、fier from overheating.

33、ent9 No Sound9 Specifications . 9 6 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 RA-1062 in furni- ture designed to house audio components. Such furniture is designed to reduce or suppre

34、ss vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. The RA-1062 is supplied with an RR-AT92 remote control and must be placed where the infrared signal from the remote can reach the

35、front panel Remote Sensor. Cables Keep power cords, digital cables, and audio cables away from each other. This will mini- mize the chance of the audio signal cables picking up noise or interference from the power cords or digital cables. Using high quality, shielded cables will also help to prevent

36、 noise or interference. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system. Remote Control The RA-1062 includes an RR-AT92 remote control that operates many of the controls of the RA-1062. In addition, the remote oper- ates basic featur

37、es of some Rotel CD players, DVD players, and AM/FM tuners. Audio Controls The RR-AT92 duplicates the basic audio func- tions of the RA-1062 front panel. When a function is available on both the front panel and the remote, a number (see front panel illustration) and a letter (see remote control illu

38、stration) are shown in the instructions. For example, to change the volume level, you can either turn the control on the front panel or use the buttons on the remote. When only one identifier appears, that control is available only on the front panel or the remote, but not both. CD Functions The PLA

39、Y, STOP, PAUSE, TRACK and , RANDOM buttons, and NUMERIC keys (0-10) operate many Rotel CD players after the CD button on the remote has been pressed. DVD Functions The PLAY, STOP, PAUSE, and TRACK , but- tons operate Rotel DVD players, after the AUX1 button on the remote has been pressed. Tuner Func

40、tions The BAND, TUNING, and additional tuning feature buttons operate Rotel tuners, after the TUNER button on the remote has been pressed. By default, the RR-AT92 operates the Rotel RT-1080 tuner. Alternatively, the remote can be reprogrammed to operate the RT-940AX tuner. This programming only need

41、s to be done once: To program for the RT-940AX: press the POWER button and the 2 button simulta- neously. To program for the RT-1080: press the POWER button and the 1 button simulta- neously. Remote Sensor The remote sensor receives infrared signals from the remote control. Do not cover or block the

42、 sensor. It must be unobstructed or the re- mote control will not work properly. The operation of the remote sensor can also be affected if it is exposed to bright sunlight or certain types of lighting (such as halogen lights) that emit infrared light. In addition re- mote control functions may not

43、work reliably if the batteries in the RR-AT92 are weak. NOTE: To use the remote, aim it at the re- mote sensor on the front panel of the RA-1062. Remote Control Batteries Two UM-4/AAA size batteries (supplied) must be installed before the remote control can be used. To install the batteries, remove

44、the cover on the back of the RR-AT92. Install the bat- teries as shown in the illustration in the bat- tery well. Test the control for proper opera- tion, then replace the cover. When the bat- teries become weak the remote control wont operate the RA-1062 consistently. Installing fresh batteries sho

45、uld eliminate the problem. NOTE: Remove the batteries from the re- mote if it will not be used for a long period of time. Do not leave run down batteries in the remote control; they can leak corrosive chemicals which will damage the unit. Speaker Outputs See Figure 3 The RA-1062 has two sets of spea

46、ker outputs, labeled SPEAKER A and SPEAKER B. The speaker outputs are controlled by the switch on the front panel. Speaker Impedance If only one set of speakers will be used at any given time, the speakers may have an imped- ance as low as 4 ohms. If there are times when both the A and B speakers wi

47、ll be used, all the speakers should have an impedance of 8 ohms or more. Speaker impedance ratings are less than precise. In practice, very few loud- speakers will present any problems for the RA- 1062. See your authorized Rotel dealer if you have any questions. Speaker Wire Use insulated two-conduc

48、tor stranded wire to connect the RA-1062 to the speakers. The size and quality of the wire can have an audible effect on the performance of the system. Stan- dard 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
