24、it will bring you many hours of enjoyment. Getting Started Thank you for purchasing the Rotel RMB-1066 Six-Channel Power Amplifier. When used in a high-quality music or home theater system, your Rotel amplifier will provide years of musical enjoyment. The RMB-1066 is a sophisticated six-channel powe

25、r amplifier. Discrete output devices, a massive power supply with toroidal trans- former, premium components, and Rotels Balanced Design ensure superb sound qual- ity. High current capability allows the RMB- 1066 to drive difficult speaker loads with ease. Operating Features Three pair of amplifier

26、channels, any of which can be bridged for mono operation (back panel switchable). Possible configu- rations: 6, 5, 4, or 3 channel operation. User selectable power on/off configuration: manual, automatic signal sensing, or con- trolled by remote 12 volt trigger signal. Front panel input level contro

27、ls. Front panel LEDs indicate Bridged Mono mode for each pair of amplifier channels. Protection circuitry with front panel indicators. Signal link output to pass-through the in- put signal to another component. A Few Precautions Please read this manual carefully. In addition to installation and oper

28、ating instructions, it provides information on various RMB-1066 system configurations. Please contact your au- thorized Rotel dealer for answers to any ques- tions you might have. In addition, all of us at Rotel welcome your questions and comments. Save the RMB-1066 shipping carton and packing mater

29、ial for future use. Shipping or moving the RMB-1066 in anything other than the original packing material may result in severe damage to your amplifier. 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 eve

30、r required. Placement The RMB-1066 generates heat as part of its normal operation. The heat sinks and venti- lation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be unobstructed. There should be 10 cm (4 inches) of clearance around the cha

31、ssis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Likewise, re- member the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its weight. Contents Figure 1: Controls and Connection

Use only this cord or an exact equivalent. Do not use an extension cord. A heavy duty multi-tap power outlet str

35、ip may be used, but only if it is rated to handle the current demand of the RMB-1066. Be sure the Power Switch on the front panel of the RMB-1066 is turned off. Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. Plug the other end into an appropriate AC ou

36、tlet. Your RMB-1066 is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 115 volts/60 Hz , Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel. NOTE: Should you move your RMB-1066 to another country, it is possi

37、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-1066 exposes you to danger- ous voltages. Consult a qualified technician or the Rotel factory service department for information. If you are goi

38、ng to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier. Power Switch and Indicator The Power Switch is located on the front panel. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The

39、LED indicator above the switch will light, indicating that the am- plifier is turned on. To turn the amplifier off, push the button again and return it to the out position. Auto Turn On/Off Mode Selector The RMB-1066 provides three options for manual or automatic power on/off operation. These modes

40、are selectable using a three- position slide switch on the back panel: With the switch in the OFF position, the amplifier is turned on or off manually us- ing the front panel power switch. Use this mode if you are using a switched AC out- let to control power to the amplifier. With the switch in the

41、 SIGNAL SENSING position, the amplifier turns on automati- cally when a signal is sensed at the inputs. The amplifier will go into standby mode after five minutes with no signal. The front panel power switch overrides this function. It must be ON for the signal sensing to work. Turn- ing the switch

42、OFF cuts power to the am- plifier, regardless of whether or not a sig- nal is present. With the switch in the +12V TRIG. position, the amplifier is turned on automatically when a 12 volt trigger signal is applied to the 3.5mm Jack to the left of the switch. The amplifier will go into standby mode af

43、ter 5 minutes with no signal if the +12 volt 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 sig- nal is present. +12V Trigger Input and

44、 Output 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 adjacent slide switch must be placed to the left position (see previ- ous section). This input accepts any control signal (AC or DC) rangi

45、ng from 3 volts to 30 volts. The jack labeled 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 Indicators Thermal and protection circu

46、its protect the am- plifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RMB-1066s pro- tection circuit is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of

47、the output devices and shuts down the amplifier if safe limits are exceeded. In addition, the RMB-1066 includes overcurrent protection which operates only when load im- pedances drop too low. This protection is in- dependent for each of the three pair of chan- nels with separate front panel PROTECTI

48、ON LEDS for each. Should a faulty condition arise, the amplifier will stop playing and one or more of the PRO- TECTION LEDS on the front panel will light. If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to iden- tify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the PROTECTION LEDS should go out. In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation lead- ing to an overheating conditi
