User manual ROTEL RMB-1085

[. . . ] Connect the component to the power outlet only with the supplied power supply cable or an exact equivalent. Rotel products are designed to comply with international directives on the Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment and the disposal of Waste Electrical and Electronic Equipment (WEEE). The crossed wheelie bin symbol indicates compliance and that the products must be appropriately recycled or processed in accordance with these directives. Do not route the power cord where it will be crushed, pinched, bent at severe angles, exposed to heat, or damaged in any way. [. . . ] Your RMB-1085 will automatically configure itself for the proper AC line voltage rating, from 110 volts to 240 volts, at 50/60Hz. Plug the supplied cord into the AC INPUT receptacle 8 on the back panel of the unit. After all connections have been made, plug the other end into an appropriate AC wall outlet. NOTE: If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier. The RMB-1085 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. 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. Thermal and protection circuits protect the amplifier against potential damage in the event of extreme or faulty operating conditions. unlike many designs , the RMB-1085's protection circuit is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if safe limits are exceeded. In addition, the RMB-1085 includes over-current protection which operates only when load impedances drop too low. Should a faulty condition arise, the amplifier channel at fault will stop playing and the PROTECTION LED on the front panel will light. If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the PROTECTION 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. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The LED indicator above the switch will light, indicating that the amplifier is turned on. [. . . ] Most difficulties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RMB-1085, refer to the suggestions for the following conditions: Power Configuration Watts/Channel all channels driven, with 20kHz filter 8 ohm load, 20Hz to 20kHz, <0. 02% THD 4 ohm load, 1kHz, <1% THD Peak Output Current Total Harmonic Distortion At rated power, 20Hz-20kHz At one-half rated power, 20Hz-20kHz At 1 watt per channel, 20Hz-20kHz Intermodulation Distortion at rated power, 60Hz:7 kHz, 4:1 Damping Factor 8 ohms Amplifier Gain Input Sensitivity/Impedance Frequency Response ±3dB Signal to Noise Ratio IHF A network Power Requirements Power Consumption Idling Power Consumption Standby Power Consumption Dimensions (W x H x D) Front Panel Height (for rack mount) Weight (net) All specifications are accurate at the time of printing.
