User manual ROTEL RB-1080

[. . . ] 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, do not expose the unit to moisture or water. Do not allow foreign objects to get into the enclosure. [. . . ] There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk. Because of its high power rating, the RB-1080 can draw considerable current. Therefore, it should be plugged directly into a 3-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 RB-1080 and all the other components connected to it. Be sure the Power Switch on the front panel of the RB-1080 is turned off (in the out position). Then, connect the supplied power cord on the back panel to the Power Connector of the amplifier and to the AC power outlet. Your RB-1080 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 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 back panel. Note: Should you move your RB-1080 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 RB-1080 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 monthlong vacation, it is a sensible precaution to unplug your amplifier (as well as other audio and video components) while you are away. The power switch is located on the front panel of your amplifier. To turn the amplifier on, push the switch in. The LED indicator above the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position. These modes are selectable using a toggle switch on the back panel. With the switch in the +12V TRIGGER ON position, the amplifier is turned on automatically when a 12V trigger signal is present at the 3. 5 mm Jack of TRIGGER IN on the rear panel. [. . . ] In practice, very few loudspeakers will present any problems for the RB-1080. See your authorized Rotel dealer if you have any questions. NOTE: To prevent loud potentially damaging noises, make sure the amplifier is turned off when you make any changes to the input signal configuration. When a component with RCA connectors ­ such as a preamplifier or surround sound processor ­ supplies signals to the RB-1080, the RCA-type phono plug inputs should be used. [. . . ]
