User manual ROTEL RC-990BX

[. . . ] Heed all warnings and safety information in these instructions and on the product itself. You must allow a minimum 10 cm or 4 inches of unobstructed clearance around the unit. Keep the component away from radiators, heat registers, stoves, or any other appliance that produces heat. WARNING: The rear panel power cord connector is the mains power disconnect device. [. . . ] 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). 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. 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. Like all audio components that handle low-level signals, the RC-990BX can be affected by its environment. we recommend installing the RC-990BX in furniture designed to house audio components. 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. use high quality RCA cables for connecting input source components to the RC-990BX. Most RCA-type output connectors are compatible with most power amplifiers. As always, use high quality cables and be sure to connect the Left and Right channel outputs of the RC-990BX to the correct channels of the amplifier. The second set of outputs may be used in custom system configurations to drive a second power amplifier or to supply a signal to a special signal processor. The Phono input is for a moving magnet (MM) or moving coil (MC) phono cartridge only and is incompatible with line level components. set the Phono Input Selector Switch as appropriate for the phono cartridge you are using. Leave the switch button in the out position for a moving magnet cartridge; push the switch in for a moving coil cartridge. The input marked Tape 2 r has been set to provide a by-pass mode for users requiring a unity gain stage through which they can use their surround sound processor. [. . . ] This minimizes the chance of interference from other components in the system. Having a separate Recording and Listening selector adds a significant degree of flexibility in how you can use the RC-990BX. For example by selecting CD with the Record Selector and selecting Tuner with the Listening Selector you can record a CD onto a tape while listening to the tuner. If you have a three-head recorder or a DAT recorder that allows simultaneous read and write operation, you can monitor your recording by pressing the TAPE 1 LISTENING button. [. . . ]
