User manual ROTEL RMB-1076

[. . . ] 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. [. . . ] 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 SIGNAL SENSING position, the amplifier turns on automatically when a signal is sensed at the inputs. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a signal is present. Position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3. The amplifier will go into standby mode with no signal if the +12 volt signal is not present. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. In addition, the RMB-1076 includes overcurrent protection which operates only when load impedances drop too low. This protection is independent for each of the three pair of channels and is indicated by the front panel PROTECTION LED. 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 use this feature the adjacent slide switch must be placed to the left position (see previous section). This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts. It is useful to think of the RMB-1076 as three stereo amplifiers in a single chassis. A rear panel switch adjacent to the inputs can select LINK to be On or Off for the first pair of amplifier channels. For Stereo mode: Slide the switch associated with the desired pair of amplifier channels to the right or OFF position. Use both LEFT and RIGHT input connectors, and connect one speaker to each pair of speaker connectors. nOTE: For groups "B" and/or "C" , you can also place the INPUT SELECT switch to the ON position for Stereo mode. This routes the input signals from the "A" group to the inputs for that pair of amplifier channels. [. . . ] The front panel PROTECTION INDICATOR is lit when the RMB-1076 protection circuits have shut off the amplifier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the amplifier itself. [. . . ]
