RT-1080 AM/FM Stereo Tuner
You may need to rotate or otherwise reorient
the antenna to find the best position.
: To use an outdoor antenna, connect its
NOTE
300 ohm twin-conductor wire instead of the
loop antenna, only after a professional con-
tractor has installed the antenna system in
accordance with local electrical codes.

FM Antenna

The RT-1080 has two FM antenna connections,
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 connec-
tors on the RT-1080. For best reception, un-
fold 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 its
NOTE
75 ohm coax lead wire to the FM connector
instead of the indoor wire antenna, only af-
ter a professional contractor has installed the
antenna system in accordance with local elec-
trical 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 country where
you purchased it (115 volts/60Hz in the USA
and 230 volts/50Hz in Europe). The AC line
configuration is noted on a decal on the back
of your unit. Make sure that your unit is con-
figured 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 trig-
ger 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 activated.
When the trigger signal is interrupted, the tuner
goes into standby mode. The front panel in-
dicator light remains lit, but the display goes
dark and the unit will not operate.
: When using the 12V Trigger feature,
NOTE
leave 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 repeaters 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-T92 remote over a hard-wired network
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 on the remote. When only
one identifier appears, that control is avail-
able only on the front panel or the remote, but
not both.

Power Button

The POWER button is located on the front panel
of the RT-1080 and is not duplicated on the
remote control.
Push the button in to turn the unit on. The LED
above the switch and the display will light up.
Push the button again (returning it to the out
position), to turn the unit off.
: If you are using a switched outlet on
NOTE
another component to power the RT-1080 or
if you are using the 12 volt trigger feature,
leave the POWER switch in the ON position.

Front Panel Display

The fluorescent display in the center of the
RT-1080 provides status information used in
operating the AM/FM receiver (such as sta-
tion frequency display, band, preset memory,
RDS information, etc.).

DIMMER Button

Available only on the remote control, this button
selects three display brightness settings: NOR-
MAL, DIM, or OFF. When the display is OFF,
pressing any button or control will return it to
the NORMAL mode. Press the button to cycle
through the three settings.
: When the tuner is turned off and back
NOTE
on, the display reverts to its normal setting.

MEMORY Button

The MEMORY button is used to confirm and
memorize various settings in the setup and
operation of the RT-1080, including tuner station
presets. Its use is described in detail in the
relevant sections that follow.
