Turn off all components in the system before changing any of the connections to the system. It is also recommended that you: Turn the volume control of the amplifi er all the way down before the amplifi er is turned on or off. Remarques importantes Pendant les branchements, assurez-vous que : Tous les maillons sont teints avant leur branchement, quels quils soient, y compris les enceintes acoustiques. teignez tous les maillons avant de modifi er quoi que ce soit au niveau de leurs branchements, quels quils soient. Il est galement recommand de : Toujours baissez le niveau sonore via le contrle de volume, avant dallumer ou dteindre lamplifi cateur. Wichtige Hinweise Achten Sie beim Herstellen der Verbindungen auf Folgendes: Schalten Sie alle Komponenten im System ab, bevor Sie Gerte (einschlielich Lautsprecher) anschlieen. Schalten Sie alle Komponenten im System ab, bevor Sie Anschlsse im System verndern. Ferner empfehlen wir, dass Sie die Lautstrke herunterdrehen, bevor Sie die Endstufe ein- oder abschalten. Notas Importantes Cuando realice las conexiones, asegrese de que: Desactiva todos los componentes del equipo, cajas acsticas incluidas, antes de conectar cualquier nuevo componente en el mismo. Desactiva todos los componentes del equipo antes de cambiar cualquier conexin del mismo. Tambin le recomendamos que: Reduzca el nivel de volumen de su amplifi cador a cero antes de activarlo o desactivarlo. Note importanti Quando effettuate i collegamenti assicuratevi di: Spegnere tutti i componenti del sistema prima di collegare qualsiasi componente, inclusi i diffusori. Spegnere tutti i componenti del sistema prima di modifi care qualsiasi connessione nel sistema. Vi raccomandiamo inoltre di: Portare il volume a zero prima di accendere o spegnere lamplifi catore. Hl belangrijk: Zorg dat niet alleen de RB-1562/1572, maar de gehele installatie uitstaat, als nog niet alle verbindingen gemaakt zijn. Zorg dat niet alleen de RB-1562/1572, maar de gehele installatie ook uitstaat, als u verbindingen gaat wijzigen.

Over the decades, we have received hundreds of awards for our products and satisfi ed 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 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 to, and fi ne 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 fi nd 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, it is especially important for a manufacturer to do all it can to engineer products that have a minimum negative impact on landfi ll sites and water tables.

We have reduced the lead content in our electronics by using special ROHS solder, while our new Class D (not digital) amplifi ers are up to fi ve times more effi cient 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 brochure on recycled paper stock. While we understand that these are small fi rst 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 About Watts The power output of the RB-1562 and RB-1572 are quoted as 100 and 250 watts, respectively, 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 amplifi ers power capability. When comparing specifi cations for different products, you should be aware that power output is often specifi ed 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 fi gure. The highly regulated power supplies of the Rotel Class D amplifi ers ensures that they will produce the full specifi ed power output to one or all channels. A loudspeakers impedance rating indicates the electrical resistance or load it offers when connected to the amplifi er, 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. So ideally, the amplifi er 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 amplifi ers power supply, because it will be drawing more current and giving off more heat. However, Rotel amplifi ers 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 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 amplifi er able to reproduce full power into all the channels at the same time, especially in the case of a volcano exploding! 7 English Getting Started Thank you for purchasing the Rotel RB-1562 or RB-1572 Stereo Power Amplifi er. When used in a high-quality music or home theater system, your Rotel amplifi er will provide years of musical enjoyment. The RB-1562 and RB-1572 are sophisticated two-channel power amplifi ers. Their Class D amplifi er circuitry, switching power supply, premium components, and Rotels Balanced Design ensure superb sound quality. High current capability allows the RB-1562 and RB- 1572 to drive diffi cult speaker loads with ease. The RB-1562 and RB-1572 are essentially identical units. They differ only in power output. In this manual the RB-1562 is most often depicted, but the RB-1572 operates in the same way. Operating Features Two amplif
