Input Signal Connections 10
[See Figure 4 for input connection illustration.]
The RC-972 has conventional RCA type input connectors, the type found on nearly all audio equipment.
Note: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections.
The CD, Tuner, and Aux inputs of the RC-972 are “line level” inputs. These are for connecting components such as CD players, Hi Fi or NICAM Stereo video cassette recorders, tuners for audio or video, Laser Disc players or the analog output from a CD ROM drive.
The Left and Right channels are clearly labeled and should be connected to the corresponding channels of the source component. The Left RCA connectors are white, the Right connectors are red. Use high quality RCA cables for connecting input source components to the RC-972. Ask your authorized Rotel dealer for advice about cables.
Note: The optional phono board card enables you to connect a phonograph to the RC-972. See your authorized Rotel dealer for more information.
Recorder Connections 11
[See Figure 5 for recorder connection illustration.]
The Tape inputs and outputs can be connected to any record/ playback device that accepts standard line level analog input and output signals. Typically that will be a conventional tape recorder.
When connecting a recorder to the RC-972 remember that the outputs of the recorder must be connected to the tape inputs of the RC-972. Similarly the tape outputs of the RC-972 must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality.
AC Power and Control
AC Power Input 14
The RC-972 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-972 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 connected to it.
Note: Do not connect the power cord for a power amplifier to the auxiliary power outlets on the RC-972. Power amplifiers often draw more power than these outlets can provide.
Your RC-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 RC-972 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. Open- ing the enclosure of the RC-972 exposes you to dangerous volt- ages. 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 components) while you are away.
Power/Standby Switch 2 15 and
Power Indicator 1
The Power Indicator light above the Standby button is always illuminated when the RC-972 is connected to a “live” AC outlet. When the Power/Standby switch is pressed the RC-972 is turned on. The Function indicator light and Volume Control indicator light will illuminate. Pressing the Standby switch again will put the RC-972 in “standby” mode and these indicator lights are turned off.
Auxiliary Power Outputs 13 (U.S.A. version)
The RC-972 has two switched outlets on the back panel. Power is available from these outlets when the RC-972 is turned on. These outlets can provide up to a total of 400 watts. They are appropriate for supplying power to signal sources, such as CD players, tuners, or tape decks. They should not be used for power amplifiers. Connecting components that will draw more than 400 watts to these outputs could damage the Standby switch in the RC-972.
