User manual ROTEL RA-311

[. . . ] 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. [. . . ] The AC line configuration is noted on a decal on the back panel. NOTE: Should you move your RA-311 amplifier to another country, it is possible to reconfigure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RA-311 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. pay particular attention to the speaker wires. 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-311 into your system as well as information that will help you get optimum sound performance. The signal from the source selected with the Function Selector is always available from these outputs. Typically these outputs are used to provide a signal to another integrated amplifier or power amplifier, which is used to drive remote speakers. Plug the cable from the turntable into the appropriate left and right phono inputs. If the turntable has a "ground" wire connect it to the screw terminal to the left of the Phono inputs. The speaker outputs are controlled by the switch 7 on the front panel. Turn off all the components in the system before connecting the speakers. The RA-311 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. route the wire from the RA-311 to the speakers. 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. [. . . ] When the RA-311 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. If you are unable to get sound from the RA-311 refer to the suggestions for the following conditions: The RA-04 has both thermal and over-current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions. the protection circuits are independent of the audio signal and have no impact on sonic performance.
