Stereo RF Modulator
15-2525
OWNER’S MANUAL —
Please read before using this equipment.
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 signals that 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 signal loss.
The modulator has two sets of inputs (front/back) so you
can connect two devices at the same time.

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