AC Power and Control
AC Power Input
The RA-1070 uses a moderate amount of
power. However there are two auxiliary power
outlets on the back of the unit, which can be
used to supply up to 200 watts of power for
other components. Consequently, the RA-1070
should be plugged directly into a 2-pin po-
larized 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 RA-1070. Power amplifiers
often draw more power than these outlets
can provide. The auxiliary power outlets
should be used only to power source
componets, such as CD players or tuners.
Your RA-1070 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 left side.
NOTE: Should you move your RA-1070
amplifier 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-1070 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 Switch and
Remote Power Button
The Power switch is located on the left side
of the front panel. When it is pressed the
RA-1070 is turned on and the front panel
displays and indicators are illuminated. When
the front panel Power button is in the “on”
position, the RR-969 Power button
can be
used to put the RA-1070 into standby mode
and return it to regular power mode. When
the RA-1070 is in standby mode the front panel
display is turned off and amplifer circuits go
into low power mode.
NOTE: The RA-1070 will be turned on
and in the normal operating mode as soon
as it is connected to the AC outlet. Be sure
to set the Volume control to the minimum
(full counterclockwise) position before con-
necting the power cord.
Auxiliary Power Outputs
(North American version only)
The RA-1070 has two switched outlets on
the back panel. Power is available from these
outlets when the RA-1070 is in regular power
mode. Power to these outlets is turned off
when the RA-1070 is in Standby mode.
These outlets can provide up to a total of
200 watts. They are appropriate for sup-
plying 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 200
watts to these outputs could damage the
Power switch in the RA-1070.
Input Signal Connections
[See Figure 3.]
The RA-1070 has conventional RCA-type con-
nectors for all inputs.
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.
Phono Input and
Ground Connection
Plug the cable from the turntable into the
appropriate left and right phono inputs. If the
turntable has a “ground” wire connect it to
the screw terminal to the left of the Phono in-
puts. It will help prevent hum and noise.
Line Level Inputs
The CD, DVD/Video, Tuner, and Aux inputs
of the RA-1070 are “line level” inputs. These
are for connecting components such as CD
players, Hi Fi or NICAM Stereo video cas-
sette recorders, tuners , 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
RA-1070. Ask your authorized Rotel dealer
for advice about cables.
Recorder Connections
[See Figure 3.]
The Tape 1 and Tape 2 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 con-
ventional tape recorder.
When connecting a recorder to the RA-1070,
remember that the outputs of the recorder must
be connected to the tape inputs of the
RA-1070. Similarly the tape outputs of the
RA-1070 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 associ-
ated components. Use high quality connect-
ing cables to prevent loss of sound quality.
