You may need to rotate or otherwise reorient

the antenna to find the best position.

NOTE

: To use an outdoor antenna, connect its

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.

NOTE

: The following instructions assume the

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.

NOTE

: To use an outdoor antenna, connect its

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.

NOTE

: When using the 12V Trigger feature,

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.

NOTE

: If you are using a switched outlet on

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.

NOTE

: When the tuner is turned off and back

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 sta-

tion presets. Its use is described in detail in

the relevant sections that follow.
