RC-972 Stereo Control Amplifier

Input Signal Connections

[See Figure 4 for input connection
illustration.]
The RC-972 has conventional RCA type in-
put 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 correspond-
ing channels of the source component. The
Left RCA connectors are white, the Right con-
nectors 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 en-
ables you to connect a phonograph to the
RC-972. See your authorized Rotel dealer
for more information.

Recorder Connections

[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

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 compo-
nents 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 of-
ten 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 am-
plifier to another country, it is possible to
reconfigure your amplifier for use on a dif-
ferent line voltage. Do not attempt to per-
form this conversion yourself. Opening the
enclosure of the RC-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/Standby Switch
and Power Indicator
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 indi-
cator lights are turned off.
Auxiliary Power Outputs
(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 out-
puts could damage the Standby switch in the
RC-972.
