User manual ROTEL RMB-1077

[. . . ] WARNING: There are no user serviceable parts inside. refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, be sure that the apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the apparatus. Do not allow foreign objects to get into the enclosure. [. . . ] Plug the other end into an appropriate AC outlet. Your RMB-1077 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel. NOTE: Should you move your RMB-1077 to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RMB-1077 exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information. 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-1077 can be turned on and off automatically by using its "12V Trigger" system. The Turn On/Off Mode Selector switch is used to select which method is used. With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. Position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3. The front panel POWER SWITCH overrides this function. it must be ON for the +12V trigger to work. 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-1077'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-1077 includes overcurrent protection which operates only when load impedances drop too low. This protection is independent for each of the seven channels. Should a faulty condition arise, the amplifier 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. [. . . ] route the wires from the RMB-1077 to the speakers. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using banana plugs, connect them to the wires and then plug into the backs of the speaker connectors. The collars of the speaker connectors should be screwed in all the way (clockwise).
