STEREO CONTROL AMPLIFIER RC-971

A Few Precautions

Please read this manual carefully. It provides complete informa- tion on how to incorporate the RC-971 into your system as well as general information that will help you get optimum sound perfor- mance. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel wel- come your questions and comments.

Save the RC-971 shipping carton and all enclosed packing mate- rial for future use. Shipping or moving the RC-971 in anything other than the original packing material may result in severe damage to your amplifier.

Fill out and send in the owner’s registration card packed with the RC-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.

Placement

Like all audio components that handle low-level signals, the RC-971 can be affected by its environment. Do not stack the RC-971 on top of a power amplifier. This will minimize chance it will pick up hum or interference. We recommend installing the RC-971 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components.

Cables

Be sure to keep the power cords, digital signal cables and regular audio signal cables in your installation away from each other. This will minimize the chance of the regular audio signal cables pick- ing up noise or interference from the power cords or digital cables. Using only high quality, shielded cables will also help to prevent noise or interference from degrading the sound quality of your system. If you have any questions see your authorized Rotel dealer for advice about the best cable to use with your system

Your RC-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 RC-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 RC-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 2 and Power Indicator 1

The Power switch is located on the left side of the front panel. When it is pushed in the RC-971 is turned on and the Power Indi- cator light is illuminated. Press the Power switch again to turn the RC-971 off.

Auxiliary Power Outputs 12 (U.S.A. version)

The RC-971 has two switched outlets on the back panel. Power is available from these outlets when the RC-971 is turned on. These outlets can provide up to a total of 400 watts. They are appropri- ate for supplying power to signal sources, such as CD players, tuners, or tape decks. They should not be used for power amplifi- ers. Connecting components that will draw more than 400 watts to these outputs could damage the Standby switch in the RC-971.

AC Power and Control

AC Power Input 13

The RC-971 does not use a significant amount of power. However there are two auxiliary power outlets on the back of the unit, which can be used to supply power for other units. Consequently it is usually best to plug the RC-971 directly into a 2-pin polarized wall outlet. Avoid the use of extension cords. 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 components con- nected to it.

Note: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RC-971. Power amplifiers often draw more power than these outlets can provide.
