User manual ROTEL RP-1001

[. . . ] The standby LED indicator will not be lit up to show the power cord is unplugged. Do not route the power cord where it will be crushed, pinched, bent, exposed to heat, or damaged in any way. Pay particular attention to the power cord at the plug and where the cord exits the back of the unit. The power cord should be unplugged from the wall outlet during a lightning storm or if the unit is to be left unused for a long period of time. [. . . ] For example, the power output may be quoted with only one channel operating, giving a higher maximum figure. The highly regulated power supplies of the Rotel Class D amplifiers ensures that they will produce the full specified power output to one or all channels. A loudspeaker's impedance rating indicates the electrical resistance or load it offers when connected to the amplifier, usually 8 ohms or 4 ohms. 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 amplifier's power supply, because it will be drawing more current and giving off more heat. 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-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, regardless of their budget, is shared by all Rotel employees. Rotel's 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. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The ring around the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position. The amplifier can be turned on and off manually, or automatically by using its "12V Trigger" system. With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. Use this mode if you are using a switched AC outlet to control power to the amplifier. ⷠWith the switch in the 12V TRIG position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. The RMB-1565 and RP-1001 generate heat as part of their normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. [. . . ] In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage. The polarity ­ the positive/negative orientation of the connections ­ for every speaker and amplifier connection must be consistent so all the speakers will be in phase. if the polarity of one connection is mistakenly reversed , bass output will be very weak and stereo imaging degraded.
