User manual ROTEL RB-1000

[. . . ] If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. Read all the instructions before connecting or operating the component. Keep this manual so you can refer to these safety instructions. [. . . ] Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if temperatures exceed safe limits. Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop playing and the LED indicator on the front panel will light up. If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem that caused the protection circuitry to engage. When you turn the amplifier back on, the protection circuit will automatically reset and the indicator LED should go out. 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. If the protection circuitry triggers repeatedly and you are unable to isolate and correct the faulty condition, contact your authorized Rotel dealer for assistance in troubleshooting. Because of its high power rating, the RB-1000 can draw considerable current. Each channel has a Clipping Indicator on the front panel. "Clippping" occurs when an amplifier it driven to the point it begins to produce distortion. The term refers to the flattening or "clipping" of the musical waveform that occurs when an amplifier is driven beyond its rated power. If the Clipping Indicators light, reduce the volume level of the system. Generally, the circuit breaker will only open under a fault condition which results in excessive current draw. to reset the circuit breaker , press the button. Should it repeatedly open, contact your authorized Rotel dealer for troubleshooting assistance. The power switch is located on the front panel of your amplifier. To turn the amplifier on, push the switch in. The LED indicator above 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. [. . . ] In most systems these controls should be turned up all the way (full clockwise position). In some situations, such as when the amplifier is part of a multi-room or bi-amplified speaker system, it may be necessary to reduce the output level. Use a small flat blade screwdriver to turn the controls down (counterclockwise) as needed. Turning down the level does not reduce the maximum output of the amplifier. [. . . ]
