Please read this manual carefully. It provi-des complete information on how to incorporate the RC-972 into your system as well as general 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.
Save the RC-972 shipping carton and all enclosed packing material for future use. Shipping or moving the RC-972 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-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.
Placement
Like all audio components that handle low-level signals, the RC-972 can be affected by its environment. To minimize the chance the RC-972 will pick up hum or interference, do not place it on top of an amplifier or any other device that has a large power transformer. Keep the RC-972 away from devices that have motors for the same reason. Do not place the RC-972 where it will be exposed to direct sunlight.
We recommend installing the RC-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.
The RC-972 is supplied with a compact, easy to use remote control
–the RR-C91. In order to take advantage of the convenience it provided, the RC-972 must be placed where you can see the Remote Sensor on the front panel.
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 picking 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
Remote Control
The RC-972 is supplied with an RR-C91 remote control. This compact unit allows you to operate many of the controls of the RC-972 from your listening location. When using the RR-C91 the emitter on the front of the control must be pointed at the RC-972 front panel.
The RR-C91 duplicates the basic functions of the front panel control. When a control is on both the front panel and the remote control, both control identifiers are shown in the related instruction text. For example, to change the volume level you can either turn the control 6 on the front panel or use the buttons
17on the remote control.
Remote Sensor 7
The Remote Sensor picks up the infrared signals 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, particularly 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-C91 are weak.
Remote Control Batteries
The supplied batteries must be installed before the remote control can be used. The battery cover is on the back of the RR-C91. Gently press the small triangular symbol on the cover and slide the cover down to expose the battery well. Install the batteries with the terminals as shown in the illustration in the battery well. Test the control for proper operation, then slide the cover back into place. When the batteries become weak the remote control won’t operate the RC-972 consistently. Installing fresh batteries should eliminate the problem.
Note: Remove the batteries from the remote control if it will not be used for a long period of time. Do not leave run down batteries in the remote control. Exhausted batteries can leak corrosive chemi- cals which will damage the unit.
Output Connections 12
[See Figure 3 for RCA output connection illustration.]
The RC-972 has RCA-type output connectors that are compatible with the inputs of most power amplifiers. Use high quality cables and be sure to connect the Left and Right channel outputs of the RC-972 to the correct channels of the amplifier.
There are two sets of outputs on the RC-972. The second set of outputs may be used in custom system configurations to drive a second power amplifier or to supply a signal to a special signal processor.
