30、67 EnglishRA1520 Stereo Integrated Amplifier 67 EnglishRA1520 Stereo Integrated Amplifier About Rotel Our story began nearly 50 years ago. Over the decades, we have received hundreds of awards for our products and satisfied hundreds of thousands of people who take their entertainment seriously - lik

31、e you! Rotel was founded by a family whose passionate interest in music led them to manufacture high-fidelity components of uncompromising quality. Through the years, that passion has remained undiminished and the family goal of providing exceptional value for audiophiles and music lovers, regardles

32、s of their budget, is shared by all Rotel employees. Rotels 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

33、 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 Rotels own factory. We all have concerns about our environment. And, as more and more electronics are produced and later discarded

34、, 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. At Rotel, we are proud to do our part. We have reduced the lead content in our electronics by using special ROHS solder, while our new Class D

35、 (not digital) amplifiers are up to five times more efficient than our legacy designs and still deliver power and performance. These products run cool, give minimum wasted energy, are good for the environment and give better sound too. Finally, we have printed this manual on recycled paper stock. Wh

36、ile we understand that these are small first steps, they are still important ones. And we continue to pursue new methods and materials for a cleaner and greener manufacturing process. All of us at Rotel thank you for buying this product. We are sure it will bring you many years of enjoyment. A Word

37、About Watts This amplifiers power output is quoted as 60 watts for each channel, when both channels are operating together at full power. Rotel has chosen to specify the power output in this way because, in Rotels experience, it gives the truest value of the receiver or amplifiers power capability.

38、When comparing specifications for different products, you should be aware that power output is often specified in other ways, so you may not be comparing like with like. For example, the power output may be quoted with only one channel operating, giving a higher maximum figure. A loudspeakers impeda

39、nce rating indicates the electrical resistance or load it offers when connected to the amplifier, usually 8 ohms or 4 ohms. The lower the impedance, the more power the speaker will need. In effect, a 4 ohm speaker will require twice as much power as an 8 ohm speaker. Contents Important Safety Instru
