26、e superb sound quality. High current capability allows the RB-1080 to drive the most demanding loud- speakers. Be aware that the RB-1080 is capable of high power levels, in excess of 200 watts per chan- nel. Make sure that your speakers can handle the power of the RB-1080. If in doubt about your spe

27、akers, ask your local Rotel audio dealer for advice. The RB-1080 is straightforward in its instal- lation and operation. If you have experience with other stereo power amplifiers, you shouldnt find anything perplexing. Plug in a pair of high-quality RCA cables from your preamp into the amplifier inp

28、uts, wire up your speakers, and enjoy. Alternatively, the RB-1080 provides an optional pair of balanced inputs for use with preamps or processors that of- fer these low-noise XLR-connections. If you choose this option, you will need to reset a back panel switch selecting the balanced in- puts. Again

29、, nothing very confusing. A Few Precautions Please read this manual carefully.

The heat sinks and ventilation openings in the amplifier are designed to

35、 dissipate this heat. The ventilation slots in the top cover must be open. There should be 10 cm (4 inches) of clearance around the chas- sis, and reasonable airflow through the in- stallation location, to prevent the amplifier from overheating. Likewise, remember the weight of the ampli- fier when

36、you select an installation location. Make sure that the shelf or cabinet can sup- port its considerable bulk. Again, use com- mon sense. About THX Ultra THX is an exclusive set of standards and tech- nologies established by the world-renowned film production company, Lucasfilm Ltd. THX grew from Geo

37、rge Lucas personal desire to make your experience of the film soundtrack, in both movie theaters and in your home the- ater, as faithful as possible to what the direc- tor intended. Movie sound tracks are mixed in special movie theaters called dubbing stages and are de- signed to be played back in m

38、ovie theaters with similar equipment and conditions. The soundtrack created for movie theaters is then transferred directly onto Laserdisc, VHS tape, DVD, etc., and is not changed for playback in a small home theater environment. THX engineers developed patented technologies to accurately translate

39、the sound from the movie theater environment into the home, correct- ing the tonal and spatial errors that occur. Before any home theater component can be THX Ultra certified, it must incorporate the THX technologies and also pass a rigorous series of quality and performance tests. Only then can a p

40、roduct feature the THX Ultra logo, which is your guarantee that the Home Theater prod- ucts you purchase will give you superb per- formance for many years to come. THX and the THX logo are trademarks of Lucasfilm Ltd. All rights reserved. AC Power and Control AC Power Input Because of its high power

41、 rating, the RB-1080 can draw considerable current. Therefore, it should be plugged directly into a 3-pin po- larized wall outlet. Do not use an extension cord. 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 an

42、d all the other components con- nected to it. Be sure the Power Switch on the front panel of the RB-1080 is turned off (in the out posi- tion). Then, connect the supplied power cord to the Power Connector on the back panel of the amplifier and to the AC power outlet. Your RB-1080 is configured at th

43、e 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

44、 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

45、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 au- dio and video components) while you are away. Power Switch and Power Indicator The power switch is located on the front panel of yo

46、ur 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 po- sition. Trigger ON/OFF Mode Selector The Amplifier provides the option

47、for manual or automatic power on/off operation. 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 automati- cally when a 12V trigger signal is present at the 3.5 mm Jack of TRIGGER IN on the rear panel. The

48、 amplifier will go into standby mode if the +12V signal is not present. The front panel POWER SWITCH overrides this function. It must be ON for the +12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. 12V Trigger Input and Output The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trigger sig- nal to turn the amplifier on and off. To use this feature the toggle switch must be set to the ON position. This input accepts any con- trol signal (AC or DC) ranging from 3 volts to 30 volts. Th
