Unpacking
Remove the unit from its packing. Look for
the handheld remote control and other ac-
cessories. Install the supplied batteries in the
remote control. Save the packing and box
as it will protect the RT-955 if you move or
need to return it for maintenance.
Placement
Place the RT-955 on a solid, dry, level sur-
face away from direct sunlight, excessive
heat, high humidity, or strong vibrations.
The RT-955 can generate some heat during
normal operation. If installed in a cabinet,
make sure that there is adequate ventilation.
Make sure there is enough room behind the
RT-955 for easy hookup. Place the unit close
to the other components in your audio/video
system and, if possible, place it on its own
shelf. This will make initial cable routing,
hookup, and any subsequent system changes
easier. It also minimizes potential interfer-
ence or heat buildup from other components.
Don’t stack heavy objects on top of the
RT-955. Do not expose the unit to moisture
as this could damage delicate circuitry and
result in a safety hazard.
Rear Panel Connections
The RT-955 provides rear panel connections
for audio line level output, two FM anten-
nas, an AM antenna, DB-9 computer inter-
face, a remote IR sensor connection, and
AC power input.
NOTE
: Do not plug any system component
into an AC source until system hookup is
complete and you are confident that all com-
ponent-to-component connections have
been properly made.
RCA Outputs
A pair of line level RCA audio outputs sends
a fixed-level stereo signal from the RT-955
to your preamplifier, system controller, or
integrated amplifier. Use a standard RCA
audio cable to connect the LEFT OUTPUT jack
to the left channel tuner input on your sys-
tem controller and the RIGHT OUTPUT jack
to the right channel tuner input on your sys-
tem controller.
AM Loop Antenna
The RT-955 includes a loop antenna to re-
ceive AM radio signals. Remove this antenna
from the box and locate it near the RT-955.
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 reori-
ent the antenna to find the best position.
NOTE
: To use an outdoor antenna, connect
its 300 ohm twin-conductor wire to the G
and AM terminals in place of the loop an-
tenna, only after a professional contractor
has installed the antenna system in accor-
dance with local electrical codes.
FM Antenna
The RT-955 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 sup-
plied with the unit. To hook up a cable or
satellite TV FM antenna system, see the in-
structions supplied with that unit.
The RT-955 is supplied with a T-
shaped indoor FM antenna. Remove
this antenna from the box and connect its
attached coax F-type plug to one of the the
FM antenna connectors on the RT-955. 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.
NOTE
: To use an outdoor antenna, connect
its 75 ohm coax lead wire to the FM con-
nector in place of the indoor wire antenna,
only after a professional contractor has in-
stalled the antenna system in accordance
with local electrical codes. In the USA, you
will need to use the supplied F-type con-
verter to connect the 75 ohm coax cable to
the antenna input.
AC Input
Your RT-955 is configured at the factory for
the proper AC line voltage in the country
where you purchased it (120 volts AC at
60Hz in the USA and 230 volts AC at 50Hz
in Europe). The AC line configuration is noted
on a decal on the back of your unit. Make
sure that your unit is configured properly for
your AC line voltage.
Plug the supplied cord into the AC INPUT
receptacle 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 system
component.
