User manual ROTEL RC-990BX

[. . . ] Do not place objects filled with liquids, such as vases, on the unit. Do not allow foreign objects to get into the enclosure. 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. [. . . ] connect the supplied power cord to the AC Input receptacle on the rear panel. Do not connect the power cord to the power outlet until all the audio input and output connections have been made. It is usually best to plug the RC-990BX 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) is rated to handle the current demanded by the components connected to it. Your RC-990BX 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). the AC line configuration is noted on a decal on the rear panel. Note: Should you move your RC-990BX amplifier to another country, it is possible to reconfigure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RC-990BX 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. If the turntable has a "ground" wire connect it to the screw terminal to the left of the Phono inputs. Tape 1 input/outputs and Tape 2 outputs can be connected to any playback/record device, Tape 2 inputs are reserved for Theater Bypass Mode, refer to bypass section. When connecting a recorder to the RC-990BX, remember that the outputs of the recorder must be connected to the tape inputs of the RC-990BX. similarly the tape outputs of the RC-990BX must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality. Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections. These are for connecting the analog outputs from components such as CD players, DVD players, video disc recorders, tuners for audio or video, or VCRs. The Left and Right channels are clearly labeled and should be connected to the corresponding channels of the source component. The Left RCA connectors are white, the Right connectors are red. use high quality RCA cables for connecting input source components to the RC-990BX. [. . . ] Remote Only Push the MUTE button on the remote once to turn the sound off. press the button again to restore previous volume levels. The LED in the volume control will flash when the unit is muted. In addition to operating many of the controls of the RC-990BX, the RR-AT97 remote control can operate basic features of some Rotel CD players, DVD players, and AM/FM tuners. [. . . ]
