CONNECTIONS
Thank you for purchasing a RadioShack Stereo RF
Modulator. Your modulator is designed to convert the
separate audio and video signals from a video camera,
computer, portable VCR, DVD player or satellite receiver
into VHF TV signalsthat you can view on a TV set
without Audio/Video (A/V) inputs. This means you can
connect a DVD player to an older TV's antenna/cable
input. The modulator's gold-plated jacks and terminals
assure maximum reliability and minimum signa ll oss.
The modulator has two sets of inputs (front/back) so you
can connect two devices at the same time.

Your modulatorhas two sets of inputs, one in the back and one in the
front. The following connection information applies to either set of inputs.

S-VideoCable (1)
Usea transformer if your
TV does nothave a VHF
75-ohm F-Connector.
You can use an S-Video
cableif the video source
has an S-Video jack.
USING A/V JACKS
The A/V jacks on your modulator are color-coded to correspond to the
colors on A/V cable plugs. Be sure to match up the jacks and plugs by
color before completing the connections.
With a Stereo Video Source
1. Plug the plugs on one
end of a stereo A/V
cable into the desired
VIDEO and AUDIO L/R
input jacks on the
modulator.
2. Plug the connectionson
the cable's otherend into
theVideo and Audio L/R
output jacks on the
video source.
3. Connect one end of a
coaxial cable to the
TO TV jack on the back
of the modulator,and the
other end to the Antenna In jack on y our TV.
With a Monaural Video Source

of the modulator,and the other end to the Antenna In jack on your TV.
USING THE S-VIDEO JACK
1. Plug one end of an S-Video
cable intothe S-VIDEO jack
on the modulator and the
other end into thevideo

4. Plug the modulator'spower cord into a
standard AC outlet.
Connection Notes
• If your TV only has 300-ohm VHF screw terminals, attach a 75- ohm to 300-ohm matching transformer to
the screw terminals and connect the coaxial cable to thetransformer to complete the connection.
• The modulator selects S-Video as the first priority if both VIDEO and S-VIDEO jacks are connected.
