The RR-AT92 Remote Control

Some functions can be done with either the front panel controls, or the supplied RR-AT92 remote control. When these operations are described, the call out number for both con- trols is shown. For example, you can select the source you want to listen to with either the

front panel Listening Selector or the re- mote control buttons .

Save the RA-972 shipping carton and all en- closed packing material for future use. Ship- ping or moving the RA-972 in anything other than the original packing material may re- sult in severe damage to your amplifier.

Fill out and send in the owner’s registration card packed with the RA-972. 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 and Control

AC Power Input

Because of its relatively high power rating, the RA-972 can draw considerable 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

Remote Sensor

The Remote Sensor picks up the infrared sig- nals from the remote control. Do not cover or block the sensor. It must be unobstructed or the remote control will not work properly. The operation of the Remote Sensor can also be affected if it is exposed to bright light, par- ticularly sunlight. Certain types of lighting, such as halogen lights, that emit a fair amount of infrared light, can also interfere with proper operation. In addition remote control functions may not work reliably if the batteries in the RR-AT92 are weak.

Note: Remove the batteries from the re- mote control if it will not be used for a long period of time. Do not leave run down bat- teries in the remote control. Exhausted bat- teries can leak corrosive chemicals which will damage the unit.

A Few Precautions

WARNING: To avoid potential damage to your system, turn off ALL the components in the system when connecting or discon- necting the loudspeakers or any associated components. Do not turn the system com- ponents back on until you are sure all the connections are correct and secure. Pay particular attention to the speaker wires. There must be no loose strands that could contact the other speaker wires, or the chassis of the amplifier.

Please read this manual carefully. It provides information on how to incorporate the RA-972 into your system as well as information that will help you get optimum sound performance. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments.

Placement

Like all audio components that handle low- level signals, the RA-972 can be affected by its environment. Avoid placing the RA-972 on top of other components. Also avoid routing audio signal cables near power cords. This will minimize the chance it will pick up hum or interference.

The RA-972 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 open. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating.

Remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support it. We recommend installing the RA-972 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 sig- nal cables and regular audio signal cables in your installation away from each other. This will minimize the chance of the regular au- dio signal cables picking up noise or inter- ference 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.

the RA-972 and all the other components con-

nected to it.

Your RA-972 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 RA-972 am- plifier to another country, it is possible to reconfigure it for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RA-972 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 au- dio and video components) while you are away.

Power Indicator and Power Control

Press the front panel Power Switch button, to turn the RA-972 on. The Power Indicator light is illuminated when the RA-972 is on. Press Power button again to turn the RA-972 off.

Once the RA-972 has been turned on with the front panel power switch, it can be switched between normal operating mode and standby

mode with the Power button on the RR-AT92 remote control. See page 8 for more information
