Through th

25、e years that passion has re- mained 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, listening to, and fine tuning each new product until it reaches thei

26、r exacting musical stan- dards. 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 capacitors from the United Kingdom and Germany, semi conductors from Japan or the United States, while toroidal power transformers are manu

27、factured in Rotels own factory. Rotels reputation for excellence has been earned through hun- dreds of good reviews and awards from the most respected re- viewers 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

28、, 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 RC-995 Stereo Control Ampli- fier. When used in a high-quality music audio system, it will pro- vide years of musical

29、 enjoyment. The RC-995 is a full featured, high performance preamplifier. All aspects of the design have been optimized to retain the full dy- namic range and subtle nuances of your music. The RC-995 has a highly regulated power supply incorporating a Rotel custom-de- signed toroidal power transform

30、er and custom-made slit foil ca- pacitors. This low impedance power supply has ample power reserves, which enables the RC-995 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 RC-995 has both XLR (balanced)

31、 and RCA cable main output connections. 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 RC-995 cir- cuitry uses metal film resistors and polystyrene or polypropylene capacitor

32、s in important signal paths. All aspects of this design have been examined with the final goal being faithful reproduction of music.

The preamp stage

36、can be used with either a moving magnet (MM) or a moving coil (MC) phono cartridge. This shows our commitment to phono sound quality and our interest in the recreation of fine music. The RC-995 is straightforward in its installation and operation. If you have experience with other stereo systems, yo

37、u shouldnt find anything perplexing. Simply plug in the associated components and enjoy. A Few Precautions Please read this manual carefully. It provides complete informa- tion on how to incorporate the RC-995 into your system as well as general information that will help you get optimum sound perfo

38、r- mance. Please contact your authorized Rotel audio retailer for an- swers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments. Save the RC-995 shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RC-995 in anyth

39、ing 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 RC-995. 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 warr

40、anty service is ever required. Placement Like all audio components that handle low-level signals, the RC- 995 can be affected by its environment. Do not stack the RC-995 on top of a power amplifier. This will minimize chance it will pick up hum or interference. We recommend installing the RC-995 in

41、furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely af- fect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio com- ponents. Cables Be sure to keep the power c

42、ords, 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 pick- ing up noise or interference from the power cords or digital cables. Using only high quality, shielded cables will also help t

43、o prevent noise or interference from degrading 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 17 The RC-995 does not use a significant amount of power. However th

44、ere are two auxiliary power outlets on the back of the unit, which can be used to supply power for other units. Consequently it is usually best to plug the RC-995 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

45、it (and the wall outlet) is rated to handle the current demanded by the components con- nected to it. Note: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RC-995. Power amplifiers often draw more power than these outlets can provide. Your RC-995 is configur

46、ed 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 configuration is noted on a decal on the left side. Note: Should you move your RC-995 amplifier to another country,

47、 it is possible to reconfigure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RC-995 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. If

48、 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 amplifier (as well as other audio and video compo- nents) while you are away. Power/Standby Switch 2 and Power Indicator 1 The Power/Standby switch is located on the left side of the front panel. When it is pressed the RC-995 is turned on and the function indicator lights are illuminated. Pressing the Standby switch again will put the RC-995 in “standby” mode and the function indicators are tu
