User manual ROTEL RB-1572

[. . . ] WARNING: There are no user serviceable parts inside. refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, do not expose the unit to moisture or water. Do not expose the unit to dripping or splashing. [. . . ] Rotel's engineers work as a close team, listening to, and fine 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. You are likely to find capacitors from the United Kingdom and Germany, semiconductors from Japan or the United States, while toroidal power transformers are manufactured in Rotel's own factory. we all have concerns about our environment. And, as more and more electronics are produced and later discarded, it is especially important for a manufacturer to do all it can to engineer products that have a minimum negative impact on landfill sites and water tables. When used in a high-quality music or home theater system, your Rotel amplifier will provide years of musical enjoyment. The RB-1562 and RB-1572 are sophisticated two-channel power amplifiers. Their Class D amplifier circuitry, switching power supply, premium components, and Rotel's Balanced Design ensure superb sound quality. High current capability allows the RB-1562 and RB1572 to drive difficult speaker loads with ease. the RB-1562 and RB-1572 are essentially identical units. In this manual the RB-1562 is most often depicted, but the RB-1572 operates in the same way. Be sure the Power Switch 1 on the front panel of the amplifier is turned off. Then, plug one end of the cord into the AC power connector 7 on the back panel of the amplifier. Plug the other end into an appropriate AC outlet. Your amplifier is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel. Note: Should you move your amplifier to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the amplifier exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information. If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier. Please contact your authorized Rotel dealer for answers to any questions you might have. [. . . ] There is an RCA input for each of the two amplifier channels. These RCA inputs accept audio signals from preamplifiers or surround sound processors. See Figure 2 The RB-1562 and RB-1572 have two sets of dual binding post speaker connection terminals, for each amplifier channel. The nominal impedance of the loudspeaker(s) connected to each channel of the amplifier should be no lower than 4 ohms. [. . . ]
