33、r Amplifiers 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 power and performance. These products run

34、 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 pursue new methods and materials for a cl

35、eaner 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 RMB-1555 power output is quoted as 120 watts for each channel, and the RMB-1585 power output is quoted as 200 watts for each ch

36、annel, when five 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 different products, you should be aware

37、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 impedance rating indicates the electrical resistance or load it offers when conne

38、cted 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 designed to work into any speaker impedance between 8 and 4 ohms, and with al

39、l the channels working up to their full power. Because the Rotel design is optimized for use with all channels 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 abl
