Unpacking  
Remote Sensor  
Remote Control  
The RC-1070 includes an RR-AT92 remote con-  
trol that operates many of the controls of the  
RC-1070. In addition, the remote operates  
basic features of some Rotel CD players, DVD  
players, and AM/FM tuners.  
Carefully remove the RC-1070, the remote  
control, and accessories from the shipping  
carton. Save the shipping carton and all en-  
closed packing material for future use. Ship-  
ping or moving the unit in anything other than  
the original packing material may result in se-  
vere damage.  
The remote sensor receives infrared signals  
from the remote control. Do not cover or block  
the sensor. It must be unobstructed or the re-  
mote control will not work properly.  
The operation of the Remote Sensor can also  
be affected if it is exposed to bright sunlight  
or certain types of lighting (such as halogen  
lights) that emit infrared light. In addition re-  
mote control functions may not work reliably  
if the batteries in the RR-AT92 are weak.  
Audio Controls  
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.  
The RR-AT92 duplicates the basic audio func-  
tions of the RC-1070 front panel. When a  
function is available on both the front panel  
and the remote, a number (front panel con-  
trols) and a letter (remote buttons) are shown  
in the instructions. For example, to change the  
volume level you can either turn the control  
on the front panel or use the buttons  
NOTE: To use the remote, aim it at the remote  
sensor on the front panel of the RC-1070.  
Placement  
Like all audio components that handle low-level  
signals, the RC-1070 can be affected by its  
environment. To minimize the chance the  
RC-1070 will pick up hum or interference, do  
not place it on top of an amplifier or any other  
device with a large power transformer. Keep  
the RC-1070 away from devices that have mo-  
tors for the same reason. Do not place the  
RC-1070 where it will be exposed to direct  
sunlight.  
Remote Control Batteries  
Two UM-4/AAA size batteries (supplied) must  
be installed before the remote control can be  
used. To install the batteries, remove the cover  
on the back of the RR-AT92. Install the batter-  
ies as shown in the illustration in the battery  
well. Test the control for proper operation, then  
replace the cover. When the batteries become  
weak the remote control won’t operate the  
RC-1070 consistently. Installing fresh batter-  
ies should eliminate the problem.  
on the remote control. When only one identi-  
fier appears, that control is available only on  
the front panel or the remote, but not both.  
CD Functions  
The PLAY, STOP, PAUSE, TRACK +/–, RAN-  
DOM buttons, and NUMERIC keys (0-10)  
operate many Rotel CD players after the CD  
button on the remote has been pressed.  
We recommend installing the RC-1070 in fur-  
niture designed to house audio components.  
Such furniture is designed to reduce or sup-  
press vibration which can adversely affect  
sound quality. Ask your authorized Rotel dealer  
for advice about component furniture and  
proper installation of audio components.  
NOTE: Remove the batteries from the remote  
if it will not be used for a long period of time.  
Do not leave run down batteries in the re-  
mote control; they can leak corrosive chemi-  
cals which will damage the unit.  
DVD Functions  
The PLAY, STOP, PAUSE, and TRACK +/–,  
buttons operate Rotel DVD players, after the  
AUX1 button on the remote has been pressed.  
The RC-1070 is supplied with an RR-AT92  
remote control and must be placed where the  
infrared signal from the remote can reach the  
front panel Remote Sensor.  
Tuner Functions  
The BAND, TUNING, and additional tuning  
feature buttons operate Rotel tuners, after the  
TUNER button on the remote has been pressed.  
Cables  
By default, the RR-AT92 operates the Rotel  
RT-955 tuner. Alternatively, the remote can be  
reprogrammed to operate the RT-940AX tuner.  
This programming only needs to be done once:  
Keep power cords, digital cables, and audio  
cables away from each other. This will mini-  
mize the chance of the audio signal cables  
picking up noise or interference from the power  
cords or digital cables. Using high quality,  
shielded cables will also help to prevent noise  
or interference. If you have any questions see  
your authorized Rotel dealer for advice about  
the best cable to use with your system.  
To program for the RT-940AX: press the  
POWER button and the 2 button simultaneously.  
To program for the RT-955: press the  
POWER button and the 1 button simultaneously.  
 
RC-1070 Stereo Control Amplifier

When connecting a recorder to the RC-1070,  
the outputsof the recorder must be connected  
to the tape inputs of the RC-1070. Similarly  
the tape outputsof the RC-1070 must be con-  
nected to the inputs of the recorder. 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.  
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 audio and video components while  
you are away.  
Signal Connections  
The RC-1070 has inputs for line level and phono  
source components, connections for audio tape  
decks, and output connections to send signals  
to power amplifiers.  
POWER/STANDBY Switch  
Power Indicator  
NOTE: To prevent loud, potentially damaging,  
noises, make sure the system is turned off  
when you make any signal connections.  
The Power Indicator light above the STANDBY  
button is always illuminated when the RC-1070  
is connected to a live AC outlet. When the  
front panel STANDBY button or remote con-  
trol POWER button is pressed, the RC-1070  
is turned on. The LISTENING control indica-  
tor lights and VOLUME CONTROL indicator  
light will illuminate. Pressing either button again  
will put the RC-1070 in standby mode and these  
indicator lights are turned off.  
NOTE: The tape inputs can also be used for  
standard playback-only source components,  
omitting the output connections.  
Outputs  
See Figure 2  
Phono Inputs  
Ground Terminal  
The RC-1070 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-1070 to the correct chan-  
nels of the amplifier.  
The RC-1070 has a built-in phono preampli-  
fier. To connect a turntable, connect the Left  
and Right RCA signal cables to the Left and  
Right RCA inputs labeled PHONO. Be sure  
to connect the Left and Right channels to the  
proper channels. Attach the ground wire from  
the turntable to the Ground screw-terminal on  
the back panel.  
Auxiliary Power Outlets  
(North American version)  
There are two sets of variable gain outputs on  
the RC-1070. The second set of outputs may  
be used in custom system configurations to drive  
a second power amplifier or to supply a sig-  
nal to a signal processor.  
The RC-1070 has two switched outlets on the  
back panel. Power is available from these  
outlets when the RC-1070 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 RC-1070.  
AC Power and Control  
Line Level Inputs  
See Figure 3  
AC Power Input  
The RC-1070 has three pair of conventional  
RCA input connectors for line level components  
such as CD players, video cassette recorders,  
tuners, Laser Disc players, or DVD players.  
These inputs are labeled CD, TUNER, and AUX.  
The RC-1070 does not use a significant amount  
of power. However there are two auxiliary  
power outlets on the back panel, which can  
be used to supply power for other units. Con-  
sequently, it is best to plug the RC-1070 di-  
rectly into a 2-pin polarized wall outlet. Avoid  
the use of extension cords. A heavy duty power  
outlet strip may be used if it (and the wall out-  
let) is rated to handle the current demanded  
by the components connected to it.  
NOTE: Do not connect a power amplifier to  
the auxiliary power outlets on the RC-1070.  
Power amplifiers often draw more power than  
these outlets can provide.  
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-1070. Ask your authorized Rotel dealer  
for advice about cables.  
12V TRIGGER Connection  
Several Rotel amplifiers can be turned on and  
off using a 12 volt trigger signal. This connection  
provides this 12 volt trigger signal. When the  
RC-1070 is activated, a 12 volt DC signal  
appears at this connector and will turn on an  
amplifier. When the RC-1070 is put in  
STANDBY mode, the trigger signal is interrupted  
and the amplifier will be turned off.  
Your RC-1070 is configured at the factory for  
the proper AC line voltage in the country where  
you purchased it (USA: 115 volts/60Hz AC  
or CE: 230 volts /50 Hz AC ). The AC line  
configuration is noted on a decal on the back  
panel. Plug the supplied cord into the AC INPUT  
receptacle on the back of the unit.  
Recorder Connections  
See Figure 3  
Tape inputs and outputs can be connected to  
any record/playback device that accepts stan-  
dard line level analog input and output sig-  
nals. Typically that will be a conventional tape  
recorder. There are two sets of tape connec-  
tions on the back panel, labelled TAPE 1 and  
TAPE 2.  
NOTE: Should you move your RC-1070 am-  
plifier to another country, it is possible to  
reconfigure your amplifier for use on a differ-  
ent line voltage. Do not attempt to perform  
this conversion yourself. Opening the enclo-  
sure of the RC-1070 exposes you to danger-  
ous voltages. Consult a qualified service  
person or the Rotel factory service department  
for information.

PHONES Output  
Rotel and the Rotel HiFi logo are registered  
trademarks of The Rotel Co, Ltd., Tokyo, Japan.  
LISTENING Selector  
The PHONES output allows you to connect  
headphones for private listening. This output  
accepts standard stereo phone (1/4”) plugs.  
If your headphones have another type of plug,  
such as a 1/8” mini-plug, you will need an  
adapter plug. Contact your authorized Rotel  
dealer, to get the correct adapter plug.  
The setting of the LISTENING selector controls  
which of the input signals goes to the main  
outputs and onto the power amplifier – or, more  
simply, which source is heard. Turn the front  
panel control to the source you want to hear,  
or press the corresponding button on the  
RR-AT92 remote.  
NOTE: Plugging in headphones does not cut  
off the signal to the outputs. In most instances,  
you should turn off the power amplifier when  
listening to headphones.  
NOTE: The AUX1 button on the remote dupli-  
cates the function of the front panel AUX but-  
ton.
