It is a massive five-channel power amplifier, capable of providing extremely high power output in the most demanding appli- cations. In fa

19、ct, the limiting factor in the RMB-1075s output levels will often be the capacity of your homes electrical supply. Dis- crete output devices, a massive power sup- ply with toroidal transformers, premium com- ponents, and Rotels Balanced Design ensure superb sound quality. High current capabil- ity a

20、llows the RMB-1075 to drive difficult speaker loads with ease. Be aware that the RMB-1075 is capable of high power levels, in excess of 120 watts per channel into 8 ohms. Make sure that your speakers can handle the power of the RMB-1075. If in doubt about your speakers, ask your authorized Rotel dea

21、ler for advice. The RMB-1075 is straightforward in its instal- lation and operation. If you have experience with other stereo power amplifiers, you shouldnt find anything perplexing. Connect high-quality RCA cables between your preamp or signal processor and the amplifier inputs, wire up your speake

22、rs, and enjoy. A Few Precautions Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RMB-1075 system configurations as well as general information that will help you get op- timum performance from your system.

The heat sinks and venti- lation openings in the amplifier are d

32、esigned to dissipate this heat. The ventilation slots in the top cover must be open. 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 ampli- fier

33、 when 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 fr

34、om George 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 bac

35、k in movie 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 tran

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 c

38、 power rating, the RMB-1075 can draw considerable current and may tax your homes electrical circuit. There- fore, it should be plugged directly into a wall outlet. Do not use an extension cord. A heavy duty multi-tap power outlet strip may be used, but only if it (and the wall outlet) is rated to ha

39、ndle the current demanded by the RMB-1075. Be sure the Power Switch on the front panel of the RMB-1075 is turned off (in the out po- sition). Then, connect the supplied power cord to the Power Connector on the back panel of the amplifier and to the AC power outlet. Your RMB-1075 is configured at the

40、 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 ei- ther 50 Hz or 60 Hz). The AC line configu- ration is noted on a label on the back panel. NOTE: Should you move your RMB-1075 to another country, it is possi

41、ble to config- ure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RMB-107 5 exposes you to danger- ous voltages. Consult a qualified technician or the Rotel factory service department for information. If you are go

42、ing 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 while you are away. Power Switch and Power Indicator The power switch is located in the center of the front panel of your amplifier. To turn the amplifier on,

43、push the switch in. The LED in- dicator above the switch will light, indicating that the amplifier is turned on. To turn the am- plifier off, push the button again and return it to the out position. Trigger ON/OFF Mode Selector The Amplifier provides the option for manual or automatic power on/off o

44、peration. 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 amplifier will go into standby mode i

45、f 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 co

46、nnecting 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. The jack labeled OUT is for connecting an- o

47、ther 3.5mm plug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a +12 volt trigger signal is applied to the IN connector. Protection Circuitry The RMB-1075 features a thermal protection circuit that protects the amplifier against po- tential dam

48、age in the event of extreme or faulty operating conditions. Unlike many designs, the RMB-1075 protection circuit is indepen- dent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if

49、 tem- peratures exceed safe limits. Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop play- ing and an LED indicator on the front panel will light.
