Over the decades,

34、 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-fidelity components of uncompromising quality. Through

35、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 to, and fine tuning, each new product until it reaches

36、 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 ma

37、nufactured in Rotels own factory. We all have concerns about our environment. And, as more and more electronics are produced it is especially important for a manufacturer to do all it can to engineer products that have a minimum impact on the environment. At Rotel, we are proud to do our part. We ha

38、ve reduced the lead content in our products by using special lead-free ROHS solder and components. Our engineers continually strive to improve power supply efficiency without compromise to quality. When in standby mode Rotel products use minimal power to meet global Standby Power Consumption require

39、ments. The Rotel factory is also doing their part to help the environment through constant improvements to product assembly methods for a cleaner and greener manufacturing processes. All of us at Rotel thank you for buying this product. We are sure it will bring you many years of enjoyment. A Word A

40、bout Watts This amplifiers power output is quoted as 120 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.

41、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

42、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. However, Rotel amplifiers are de

43、signed to work into any speaker impedance between 8 and 4 ohms, and with all the channels working up to their full power. Because Rotel designs are optimized for use with all channels operating together, Rotel is able to specify the true power output for both channels. Contents Important Safety Inst
