Computer I/O Connector
The RA-1070 can be operated from a per-
sonal computer running audio system control
software from third-party developers. This con-
trol is accomplished by sending the operat-
ing codes normally sent by the RR-969 remote
control over a hard-wired network connec-
tion from the computer.
The COMPUTER I/O input provides the nec-
essary connection on the back panel. It ac-
cepts standard RJ-45 8-pin modular plugs,
such as those commonly used in 10-BaseT UTP
Ethernet cabling.
For additional information on the connections,
software, and operating codes for computer
control of the RA-1070, contact your autho-
rized Rotel dealer.
Audio Controls
Volume Controls and
The front panel Volume control increases
or decreases the volume in both channels at
the same time. Turn it clockwise to increase
the volume or counterclockwise to decrease
the volume. On the RR-969 remote Volume
Button
, press the ▲ to increase volume
or ▼ to decrease volume.
Listening Selector Buttons
and Display
Press one of the Listening Selector Buttons
to select the input signal that goes to the main
outputs and to the power amplifier – or, more
simply, which source is heard. The source
selected is shown in the front panel FL Dis-
play
.
Recording Selector Buttons
and Display
Press one of the Recording Selector Buttons
to select the input signal that goes to the record
outputs. The source selected is shown in the front
panel FL Display
. When you are not re-
cording, press the Off button. This minimizes
the chance of interference from other compo-
nents in the system.
Having a separate Recording and Listening
selector adds a significant degree of flexibil-
ity in how you can use the RA-1070. For ex-
ample by selecting CD with the Record Se-
lector and selecting Tuner with the Listening
Selector you can record a CD onto a tape while
listening to the tuner.
If you wish to duplicate (“dub”) a recording
from one recorder to another, the source unit
must be connected to Tape 1 in/outputs. Press
the Tape 1 Recording Selector button. Con-
nect the unit recording the signal to the Tape
2 in/outputs.
Contour Control
Instead of conventional tone controls, the
RA-1070 has a front-panel Contour control
which selects one of five available settings.
Each setting provides a fixed frequency con-
tour 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.
Phones Output
The Phones output allows you to connect head-
phones for private listening. This output ac-
commodates 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 autho-
rized Rotel dealer, to get the correct adapter
plug. Plugging in a set of headphones does
not cut off the signal to the outputs. Use the
Speaker Selector to turn off the speakers. The
setting of the Listening Selector controls which
source is heard. Turn the front panel Listen-
ing Selector to the source you want to listen
to. Or press the corresponding source button
on the remote control.
NOTE: Because the sensitivity of speakers
and headphones can vary widely, always
reduce the volume level before connecting
or disconnecting headphones.
