28、 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 like you! Rotel was founded by a family whose passionate interest in music led them to manufacture high-fi

29、delity 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, regardless of their budget, is shared by all Rotel employees. Rotels engineers work as a close team, listening t

30、o, 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 Un

31、ited 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, it is especially important for a manufacturer to do all it can to engineer products that have a minim

32、um 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 (not digital) amplifiers are up to five times more efficient than our legacy designs and still deliver

33、 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 brochure on recycled paper stock. While we understand that these are small first steps, they are still important ones. And we continue to

34、 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 About Watts The RB-1552 power output is quoted as 130 watts for each channel, and the RB-1582 power o

35、utput is quoted as 200 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. When comparing specifications for

36、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. The high performance power supplies of the Rotel amplif

37、iers ensure that they will produce the full specified power output to one or both channels. A loudspeakers impedance 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.

38、In effect, a 4 ohm speaker will require twice as much power as an 8 ohm speaker. So ideally, the amplifier should be give double the power into a 4 ohm load a rating of 100 watts into an 8 ohm load should become 200 watts into 4 ohms. Using lower impedance speakers makes greater demands on the ampli

39、fiers power supply, because it will be drawing more current and giving off more heat. However, Rotel amplifiers are designed to work into any speaker impedance between 8 and 4 ohms, and with all the channels working up to their full power. Because the Rotel design is optimized for use with all chann

40、els operating together, Rotel is able to specify the true power output for both channels. This can be important for your enjoyment, too. When watching movies, its nice to have the amplifier able to reproduce full power into all the channels at the same time, especially in the case of a volcano explo
