User manual ROTEL RA-2040

[. . . ] Heed all warnings and safety information in these instructions and on the product itself. You must allow 10 cm or 4 inches of unobstructed clearance around the unit. Do not place the unit on a bed, sofa, rug, or similar surface that could block the ventilation slots. If the component is placed in a bookcase or cabinet, there must be ventilation of the cabinet to allow proper cooling. [. . . ] However, whenever possible, it should be plugged directly into a 2-pin polarized wall outlet. A heavy duty multi-tap power outlet strip may be used if it (and the wall outlet) can handle the current demanded by the RA-2040 and all the other components connected to it. Your RA-2040 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 120 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). NOTE: Should you move your RA-2040 amplifier to another country, it is possible to reconfigure it for use on a different line voltage. Opening the enclosure of the RA-2040 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. If you are going to be away from home for an extended period of time such as a month-long vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away. WARNING: To avoid potential damage to your system, turn off ALL the components in the system when connecting or disconnecting the loudspeakers or any associated components. Do not turn the system components back on until you are sure all the connections are correct and secure. There must be no loose strands that could contact the other speaker wires, or the chassis of the amplifier. It provides information on how to incorporate the RA-2040 into your system as well as information that will help you get optimum sound performance. use high quality RCA cables for connecting input source components to the RA-2040. Turn off all the components in the system before connecting the speakers. The RA-2040 has colorcoded binding post type speaker connectors on the back panel (except in European Community countries where their use is not permitted). These connectors accept bare wire, connector lugs, or dual banana type connectors. Give yourself enough slack so you can move the components to allow access to the speaker connectors. If you are using dual banana plugs, connect them to the wires and then plug into the backs of the binding posts. The thumbscrews of the binding posts should be screwed in all the way (clockwise). If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip the insulation from the end of each conductor. NOTE: Be sure there are no loose wire strands that could touch adjacent wires or connectors. ] The Tape inputs and outputs can be connected to any record/playback device that accepts standard line level analog input and output signals. When connecting a recorder to the RA-2040 remember that the outputs of the recorder must be connected to the tape inputs of the RA-2040. [. . . ] When the Monitor Control is set to the Source position, the signal you hear, and which goes to the Preamp Outputs, is selected by the Function Control. Some audio components can be turned on automatically when they receive a 12V turn on "signal". When the RA-2040 is in Standby mode, the trigger signal is interupted, so the components controlled by it are turned off. 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. [. . . ]
