RT-1080 AM/FM Stereo Tuner

Rear Panel Connections

The RT-1080 provides rear panel connections
for audio line level output, two FM antennas,
an AM antenna, computer interface, a remote
IR connection, 12V trigger connections for re-
mote turn-on and AC power input.
: Do not plug any system component into
NOTE
an AC source until system hookup is complete
and you are sure that all connections have
been properly made.

RCA Outputs

A pair of line level RCA audio outputs sends
a fixed-level stereo signal from the RT-1080 to
your preamplifier, surround processor, or inte-
grated amplifier. Use a standard RCA audio
cable to connect the left output jack to the left
channel tuner input on your system controller
and the right output jack to the right channel
tuner input on your system controller.

AM Loop Antenna

The RT-1080 includes a loop antenna to receive
AM radio signals. Remove this antenna from
the box and locate it near the RT-1080.
Connect the 300 ohm twin-conductor wire
from the loop antenna to the pair of screw
terminals labeled AM LOOP, attaching one
wire to each terminal. It does not matter
which wire attaches to which terminal, but
make sure that the connections are solid and
that the two wires do not touch.
You may need to rotate or otherwise reorient
the antenna to find the best position.
: To use an outdoor antenna, connect
NOTE
its 300 ohm twin-conductor wire instead of
the loop antenna, only after a professional
contractor has installed the antenna system in
accordance with local electrical codes.

FM Antenna

The RT-1080 has two FM antenna connec-
tions, labeled A and B. This permits you to
switch between two different FM antenna
systems using a front panel or remote control
switch. This feature could be useful to switch
between an indoor antenna and an outdoor
antenna system or between a standard FM
antenna and a cable or satellite TV decoder
that provides an FM antenna signal.
: The following instructions assume the
NOTE
use of a standard FM wire antenna supplied
with the unit. To hook up a cable or satellite
TV FM antenna system, see the instructions
supplied with that unit.
The RT-1080 is supplied with a T-shaped in-
door FM antenna. Connect the attached coax
F-type plug to one of the FM antenna con-
nectors on the RT-1080. For best reception,
unfold the T-shaped antenna. Eyelets at both
ends of the T allow tacking the antenna to a
wall, if desired. Experiment with positioning
for best reception.
: To use an outdoor antenna, connect
NOTE
its 75 ohm coax lead wire to the FM connec-
tor instead of the indoor wire antenna, only
after a professional contractor has installed
the antenna system in accordance with lo-
cal electrical codes. In the USA, you will
need to use the supplied F-type converter
to connect the 75 ohm coax cable to the
antenna input.

AC Input

Your RT-1080 is configured at the factory
for the proper AC line voltage in the coun-
try where you purchased it (120 volts/60Hz
in the USA and 230 volts/50Hz in Europe).
The AC line configuration is noted on a de-
cal on the back of your unit. Make sure that
your unit is configured properly for your AC
voltage.
Plug the supplied cord into the AC input re-
ceptacle on the back of the unit. Once all
other rear panel connections are completed,
plug the power cord into an AC wall outlet or
switched AC outlet on another component.

12V TRIGGER Connections

The RT-1080 can be activated by a 12 volt
trigger signal from a Rotel preamplifier.
These two connections provide an input to
receive the 12 volt trigger signal from the
preamp and an output to pass through the
trigger signal to another component such as
a Rotel power amplifier.
The trigger input accepts any control signal
(AC or DC) ranging from 3 volts to 30 volts.
When a cable is connected to the input and
a trigger signal is present, the tuner is acti-
vated. When the trigger signal is interrupted,
12
the tuner goes into standby mode. The front
panel indicator light remains lit, but the display
goes dark and the unit will not operate.
: When using the 12V Trigger feature, leave
NOTE
the POWER button in the ON position.

EXT REM. IN Jack

This 3.5mm jack receives command codes
from industry-standard infrared receivers
(Xantech, etc.) via hard-wired connections.
This feature could prove useful when the unit
is installed in a cabinet and the front panel
sensor is blocked. Consult your authorized
Rotel dealer for information on external re-
peaters and the wiring of a jack to fit the
receptacle.

COMPUTER I/O Interface

The unit can be operated from a home auto-
mation controller or a computer running au-
dio system control software from third-party
developers. This control is accomplished by
sending the operating codes normally sent
by the RR-T93 remote over a hard-wired net-
work connection 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 information on the connections, software,
and operating codes for computer control,
contact your authorized Rotel dealer.

Basic Operating Controls

The following explanations will help you get
familiar with the features and controls. When
a function is available on both the front panel
and the remote, a number (see front panel
illustration) and a letter (see remote control
illustration) are shown in the instructions. For
example, to change from the AM to FM band,
you can either press the front panel button
or use the button
only one identifier appears, that control is
available only on the front panel or the re-
mote, but not both.
