Auxiliary Power Outlets
(North American version)
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.
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.
12V TRIGGER Connection
Several Rotel amplifiers can be turned on and
off using a 12 volt trigger signal. This con-
nection 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 inter-
rupted and the amplifier will be turned off.
Audio Controls
The following controls are used to operate
the RC-1070.
VOLUME Control
Turn the front panel VOLUME control clock-
wise to increase the volume, or counterclock-
wise to decrease the volume. Alternatively,
press the VOL buttons on the remote control
to adjust the volume up or down
CONTOUR Selector
Instead of conventional tone controls, the
RC-1070 has a front-panel CONTOUR con-
trol which selects one of five available set-
tings. Each setting provides a fixed frequency
contour as follows:
OFF: the tone contour circuits are bypassed
to ensure the purest possible sound.
L-1: moderate increase in bass frequencies
(typically +3dB @ 100Hz).
L-2: more increase in bass frequencies (typi-
cally +4dB @ 100Hz).
H: moderate increase in high frequencies
(+3dB @ 10kHz).
LH: combination of L-2 bass and H high fre-
quency increases.
LISTENING Selector
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-AT94 remote.
NOTE
: The AUX1 button on the remote du-
plicates the function of the front panel AUX
button.
RECORDING Selector
The RC-1070 can record from any input
source (except TAPE 2) to a recorder con-
nected to TAPE 1 or TAPE 2 outputs. To se-
lect an input source for recording, turn the
RECORDING control on the front-panel to
the desired source.
This selection is independent of the source
selected for listening. While recording, you
may still select a different source using the
LISTENING selector.
If you have a three-head recorder or a DAT
recorder that allows simultaneous read and
write operation, you can monitor your record-
ing by setting the LISTENING switch to the
TAPE 1 or TAPE 2 position.
NOTE
: If you select TAPE 1 with the RECORD-
ING control, the recording signal will only be
available at the TAPE 2 recording outputs, not
the TAPE 1 outputs. To dub a tape, select TAPE
1 and record to the tape deck connected to
the TAPE 2 outputs.
MUTE Button
To temporarily mute the sound of the sys-
tem press the MUTE button on the RR-AT94
remote. Press the button again to return the
sound volume to the original level. The LED
in the volume control will flash when the unit
is muted.
PHONES Output
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.
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.
Troubleshooting
Most difficulties in audio systems are the result
of incorrect connections, or improper control
settings. If you encounter problems, isolate the
area of the difficulty, check the control settings,
determine the cause of the fault and make the
necessary changes. If you are unable to get
sound from the RC-1070, refer to the sugges-
tions for the following conditions:
Power Indicator Is Not Lit
The POWER indicator should be lit whenever
the RC-1070 is plugged into the wall power
outlet. If it does not light, test the power out-
let with another electrical device, such as a
lamp. Be sure the power outlet being used
is not controlled by a switch that has been
turned off.
Fuse Replacement
If another electrical device works when plugged
into the power outlet, and the Power Indicator
still will not light, it indicates that the internal
power fuse may have blown. If you believe
this has happened, contact your authorized
Rotel dealer to get the fuse replaced.
