Shipping or moving the RB-1072 in anything other than the original packing material may result in severe damage to your amplifi er. Be sure to keep the original sale

34、s receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required. Placement The RB-1072 generates heat as part of its normal operation. The heat sinks and ventila- tion openings in the amplifi er are designed to dissipate this heat. The ve

35、ntilation slots in the top cover must be unobstructed. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airfl ow through the installation location, to prevent the amplifi er from overheating. Likewise, remember the weight of the amplifi er when you select an installat

36、ion location. Make sure that the shelf or cabinet can support its weight.

Use only this cord or an exact equivalent. Do not use an extension cord. A heavy

39、 duty multi-tap power outlet strip may be used, but only if it is rated to handle the current demand of the RB-1072. Be sure the Power Switch on the front panel of the RB-1072 is turned off. Then, plug one end of the cord into the AC power connector 8 on the back panel of the amplifi er. Plug the ot

40、her end into an appropriate AC outlet. Your RB-1072 is confi gured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line confi guration is noted on a label on the back panel. NOTE: Should you move your RB-1072

41、 to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this con- version yourself. Opening the enclosure of the RB-1072 exposes you to dangerous volt- ages. Consult a qualified technician or the Rotel factory service department

42、for infor- mation. If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifi er. Power Switch and Indicator 12 The Power Switch is located on the front panel. To turn the amplifi er on (or to activate either of the optional automatic pow

43、er-on modes), push the switch in. The LED indicator above the switch will light, indicating that the amplifi er is turned on. To turn the amplifi er off, push the button again and return it to the out position. Turn On/Off Mode Selector 6 The RB-1072 can be turned on and off auto- matically by using

44、 its “12V Trigger” system. The Turn On/Off Mode Selector switch is used to select which method is used. With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. With the switch in the 12V TRIG. position, the amplifier is turned on automatica

45、lly when a 12 volt trigger signal is applied to the 3.5mm Jack labeled IN. 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 Inpu

46、t and Output 7 The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trigger signal to turn the amplifi er on and off. To use this feature the adjacent switch 6 must be set in the 12V TRIG position (see previous section). This input accepts any control signal (AC or DC) rang

47、ing from 3 volts to 30 volts. The jack labeled OUT is for connecting another 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 Indicator 3 Thermal and protection circu

48、its protect the am- plifi er against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RB-1072s protection circuit is independent 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 amplifi er if safe limits are exceeded. In addition, the RB-1072 includes overcurrent protection which operates only when load impedances drop too low. S
