Their comments keep the company true to its goal the pursuit of equipment that is musi- cal, reliable and affordable. All of us at Rotel thank you for buying this product

22、and hope it will bring you many hours of enjoyment. Getting Started Thank you for purchasing the Rotel RB-1070 Stereo Power Amplifier. When used in a high- quality music or home theater system, it will provide years of musical enjoyment. The RB-1070 is a high-power, two-channel power amplifier, prov

23、iding the highest level of audio performance. Discrete output devices, a massive power supply, premium components, and Rotels Balanced Design ensure superb sound quality. High current capability allows the RB-1070 to drive the most demanding loud- speakers. Be aware that the RB-1070 is capable of hi

24、gh power levels, in excess of 130 watts per chan- nel. Make sure that your speakers can handle the power of the RB-1070. If in doubt about your speakers, ask your authorized Rotel dealer for advice. The RB-1070 is straightforward in its instal- lation and operation. If you have experience with other

25、 stereo power amplifiers, you shouldnt find anything perplexing. Plug in a pair of high-quality RCA cables from your preamp into the amplifier inputs, wire up your speakers, and enjoy. A Few Precautions Please read this manual carefully. In addition to basic installation and operating instructions,

26、it provides valuable information on various RB-1070 system configurations as well as gen- eral information that will help you get opti- mum performance from your system. Please contact your authorized Rotel dealer for an- swers to any questions you might have. In ad- dition, all of us at Rotel welco

27、me your ques- tions and comments. Save the RB-1070 shipping carton and all en- closed packing material for future use. Ship- ping or moving the RB-1070 in anything other than the original packing material may re- sult in severe damage to your amplifier. Fill out and send in the owners registration c

28、ard packed with the RB-1070. Also be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required.

31、cations . 8 6 Placement The RB-1070 generates heat as part of its nor- mal operation. The heat sinks and ventilation openings in the amplifier are designed 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 chas- sis,

32、 and reasonable airflow through the in- stallation location, to prevent the amplifier from overheating. Likewise, remember the weight of the ampli- fier when you select an installation location. Make sure that the shelf or cabinet can sup- port its considerable bulk. Again, use com- mon sense. AC Po

33、wer and Control AC Power Input Because of its high power rating, the RB-1070 can draw considerable current. Therefore, it should be plugged directly into a 2-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) i

34、s rated to handle the current demanded by the RB-1070 and all the other components con- nected to it. Be sure the power switch on the front panel of the RB-1070 is turned off (in the out posi- tion). Then, connect the supplied power cord to the AC power outlet. Your RB-1070 is configured at the fact

35、ory 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-1070 amplifier to another country, it is possi

36、ble 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-1070 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information. If you are go

37、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 (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 your amp

38、lifier. 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 for ma

39、nual 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 ampli

40、fier 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 Outp

41、ut The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trig- ger signal 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 control signal (AC or DC) ranging from 3 volts to 30 volts. The jack label

42、ed OUT is for connecting an- other 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 RB-1070 features a thermal protection cir- cuit that protects the am

43、plifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RB-1070s 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 an

44、d shuts down the amplifier if 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 the LED indicator on the front panel will light up. If this happens, turn the amplifie

45、r off, let it cool down for several minutes, and attempt to iden- tify and correct the problem that caused the protection circuitry to engage. When you turn the amplifier back on, the protection circuit will automatically reset and the indicator LED should go out. In most cases, the protection circu

46、itry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation lead- ing to an overheating condition. In very rare cases, highly reactive or extremely low im- pedance speaker loads could cause the pro- tection circuit to engage. If the protection circuitry trigg

47、ers repeatedly and you are unable to isolate and correct the faulty condition, contact your authorized Rotel dealer for assistance in troubleshooting. Input Signal Connection See Figure 2 for normal stereo wir- ing illustration. The RB-1070 has conventional RCA type in- put connectors, the type foun

48、d on nearly all audio equipment. Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the amplifier is turned off when you make any signal connections. Select a high quality pair of audio intercon- nect cables. Connect the left channel output of your preamp to the left channel input on the RB-1070. Connect the right channel output of your preamp to the right channel input.
