The RB-971 is a high-power, two-channel power amplifier, provid- ing the highest level of audio performance. Discrete output de- vices, a massive power supply, premium components, and Rotel’s Balanced Design ensure superb sound quality. High current capa- bility allows the RB-971 to drive the most demanding loudspeakers.
Be aware that the RB-971 is capable of high power levels, in ex- cess of 70 watts per channel. Make sure that your speakers can handle the power of the RB-971. If in doubt about your speakers, ask your local Rotel audio retailer for advice.

A Few Precautions
Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RB-971 system configurations as well as general informa- tion that will help you get optimum performance from your system. Please contact your authorized Rotel audio retailer for answers to any questions you might have. In addition, all of us at Rotel wel- come your questions and comments.
Save the RB-971 shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RB-971 in anything other than the original packing material may result in severe dam- age to your amplifier.
Fill out and send in the owner’s registration card packed with the RB-971. 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.
AC Power Input 6
Because of its high power rating, the RB-971 can draw consider- able current. Therefore, it should be plugged directly into a 2-pin polarized 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-971 and all the other components connected to it.
Be sure the power switch on the front panel of the RB-971 is turned off (in the out position). Then, connect the supplied power cord to the AC power outlet.
Your RB-971 is configured at the 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-971 amplifier to another country, it is 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-971 exposes you to dangerous voltages. Consult a qualified service person or the Rotel factory service department for information.
If you 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 audio and video compo- nents) while you are away.
Power Switch 1 and Power Indicator 2
The power switch is located on the front panel of your 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 position.
