24、uality founded Rotel 40 years ago. Over the years that passion has remained undiminished and the 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

25、 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 ca- pacitors from the United Kingdom and Ger- many, semi-conductors from Japan or the United States, and to

26、roidal power transformers manufactured 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

27、 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 of enjoyment. Getting Started Thank you for purchasing the Rotel RA-1070 Stereo Integrated Amplifier. When used in a high-quality music audio system, it w

28、ill pro- vide years of musical enjoyment. The RA-1070 is a full featured, high perfor- mance preamplifier. All aspects of the design have been optimized to retain the full dynamic range and subtle nuances of your music. The RA-1070 has a highly regulated power sup- ply incorporating a Rotel custom-d

29、esigned to- roidal power transformer and custom-made slit foil capacitors. This low impedance power supply has ample power reserves, which en- ables the RA-1070 to easily reproduce the most demanding audio signals. This type of design is more expensive to manufacture, but it is better for the music.

This insures that the precise timing

35、 of the music is maintained and faithfully recreated. The RA- 1070 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in im- portant signal paths. All aspects of this de- sign have been examined with the final goal being faithful reproduction of music. The RA-1070 has a

36、superb phono preamp stage. It is designed for use with popular mov- ing magnet (MM) phono cartridges. This shows our commitment to phono sound quality and our interest in the recreation of fine music. The RA-1070 is straightforward in its instal- lation and operation. If you have experience with oth

37、er stereo systems, you shouldnt find anything perplexing. 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 RA-1070 into your system as well as gen- eral information that will help you

38、 get opti- mum 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 com- ments. Save the RA-1070 shipping carton and all en- closed packing material for future use. Ship- ping or moving

39、the RA-1070 in anything other than the original packing material may re- sult in severe damage to your amplifier. Fill out and send in the owners registration card packed with the RA-1070. Also be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will

40、 need in the event warranty service is ever required. Placement Like all audio components that handle low- level signals, the RA-1070 can be affected by its environment. Do not stack the other com- ponents on top of the RA-1070. That will impede the ability of the amplifier to venti- late the heat i

41、t generates. Also, do not stack the RA-1070 on top of other components. This will minimize chance the other components will pick up hum or interference from the RA-1070. We recommend installing the sys- tem components in furniture designed to house audio components. Such furniture is designed to red

42、uce or suppress vibration which can ad- versely affect sound quality. Ask your autho- rized Rotel dealer for advice about compo- nent furniture and proper installation of au- dio components. Cables Be sure to keep the power cords, digital sig- nal cables and regular audio signal cables in your insta

43、llation away from each other. 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 you

44、r system. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system RR-969 Remote Control The RA-1070 includes a full-function learn- ing remote control that can operate up to nine other components, in addition to the RA-1070. A separate manua

45、l, included with the remote, gives detailed instrctions on programming and using the RR-969 to replace all of the remote controls in your system. To avoid duplication, we provide only basic information about us- ing the RR-969 to operate the RA-1070. Most of the RR-969 functions duplicate the front

46、panel controls. In this manual the remote con- trol functions are covered in the same section as the front panel control operation. Numbers in gray boxes such as indicate items on the front and rear panel control and connec- tion illustrations. See Figure 1 on page 3. Letters in gray boxes such as i

47、ndicate items on the RR-969 illustration. See Figure 2 on page 3. Using the RR-969 To operate the RA-1070 with the remote, activate the AUDIO mode, if necessary, by pressing the AUD button . The AUDIO mode will remaine selected until another DEVICE button is pressed. Controlling Other Components To

48、control other components with the RR-969, press the appropriate Device Selection but- ton. See the RR-969 manual for more infor- mation. Remote Sensor The Remote Sensor is located to the right of the Power button on the front panel. It picks up the infra-red signals from the remote control. Do not cover or block the sensor. It must be clear of obstructions or t
