Through the years that passion has re- mained undiminish

19、ed 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 their exacting musical stan- dards. They are free

20、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 manufactured in Rotels own factory. Rotels reputat

21、ion 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, reliable and affordable. All of us at Rotel

22、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-932 Stereo Integrated Am- plifier. When used in a high-quality music audio system, it will pro- vide years of musical enjoyment. The RA-932 is a full featured,

23、high performance component. All aspects of the design have been optimized to retain the full dy- namic range and subtle nuances of your music. The RA-932 has a highly regulated power supply incorporating a Rotel custom-de- signed toroidal power transformer and custom-made slit foil ca- pacitors. Thi

24、s low impedance power supply has ample power reserves, which enables the RA-932 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 (PCB) are designed with Symmetrical Circuit Traces. T

25、his insures that the precise timing of the music is maintained and faithfully recreated. The RA-932 circuitry uses metal film resistors and polystyrene or polypropylene capacitors in important signal paths. All aspects of this design have been ex- amined to ensure the most faithful music reproductio

26、n. In addition the RA-932 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-932 are easy to install and use. If you have experience with other stereo systems, you shouldnt find anyth

27、ing perplexing. Simply plug in the associated components and enjoy.

30、 components in the system when connecting or disconnecting the loudspeakers or any associated components. Do not turn the system components back on until 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

31、contact the other speaker wires, or the chassis of the amplifier. Please read this manual carefully. It provides information on how to incorporate the RA-932 into your system as well as information that will help you get optimum sound performance. Please contact your authorized Rotel dealer for answ

32、ers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments. Save the RA-932 shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RA-932 in anything other than the original packing material may result in severe dam- a

33、ge to your amplifier. Fill out and send in the owners registration card packed with the RA-932. 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. Placement Like all audio components tha

34、t handle low-level signals, the RA-932 can be affected by its environment. Avoid placing the RA-932 on top of other components. Also avoid routing audio signal cables near power cords. This will minimize the chance it will pick up hum or interference. The RA-932 generates heat as part of its normal

35、operation. The heat sinks and ventilation 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 loca- tion, to prevent the a

36、mplifier from overheating. Remember the weight of the amplifier when you select an installa- tion location. Make sure that the shelf or cabinet can support it. We recommend installing the RA-932 in furniture designed to house audio components. Such furniture is designed to reduce or sup- press vibra

37、tion 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, digital signal cables and regular audio signal cables in your installation away from each other. T

38、his 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 to prevent noise or interference from degrading the sound quality of your system. If you have any questio

39、ns see your authorized Rotel dealer for advice about the best cable to use with your system. AC Power and Control AC Power Input 18 The RA-932 does not draw high levels of current from the power outlet. However, when ever possible, it should be plugged directly into a 2-pin polarized wall outlet. Do

40、 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-932 and all the other components connected to it. Your RA-932 is configured at the factory for the proper AC line voltage in the country where you p

41、urchased 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 back panel. Note: Should you move your RA-932 amplifier to another country, it is possible to reconfigure it for use on a different line voltage. Do

42、not attempt to perform this conversion yourself. Opening the enclosure of the RA-932 exposes you to dangerous voltages. Con- sult a qualified service person or the Rotel factory service depart- ment for information. If you are going to be away from home for an extended period of time such as a month

43、-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 Indicator 2 and Power Switch 3 Push in the Power Switch button to turn the RA-932 on. The Power Indicator light is illuminated when the RA-932 is on. Press a

44、nd re- lease the Power Switch button again to turn the RA-932 off. Auxiliary Power Outlet 17 (U.S.A. version only) The RA-932 has a switched power outlet on the back panel. Power is available from this outlet when the RA-932 is turned on. This outlet can provide up to 150 watts. It is appropriate fo

45、r supplying power to signal source, such as a CD player, tuner, or tape deck. Do not connect a power amplifier to this power outlet. Connect- ing a component that draws more than 150 watts to this outlet could damage the Power Switch of the RA-932. 12 Volt Trigger Outlet 16 Some audio components can

46、 be turned on automatically when they receive a 12V turn on “signal”. The 12V Trigger Output of RA-932 provides the required signal. Connect the compatible com- ponents to the RA-932 with a conventional 1/8” miniplug cable. STEREO INTEGRATED AMPLIFIER RA-932 7 English Input Signal Connections The RA

47、-932 has conventional RCA type input connectors, the type found on nearly all audio equipment. Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections. Phono Input 11 and Ground Wire Connection 10 See Fi

48、gure 3 for phono input connection illustration. Plug the cable from the turntable into the appropriate left and right phono inputs. Most turntables also have a “ground” wire. Connect it to the screw terminal to the left of the Phono inputs. It will help prevent hum and noise. Line Level Inputs 12 See Figure 2 for line level input connection illustration. The CD, Tuner, and Aux inputs of the RA-932 are all “line level” in- puts. These are for connecting components such as CD players, Hi Fi or NICAM Stereo video cassette recorders, tuners for audio or video
