A RF Modulator is an electronic device for converting audio/video signals into a RF (radio frequency) signal. RF modulators are used to connect DVD players, video game systems, camcorders and other video components to TV sets without Audio/Video inputs. The connection is made from the DVD (or other component) a/v outputs to the RF Modulator and from the RF Modulator to the TV's antenna input jack.

• Combines audio/video line-level signals into an RF output signal. (necessary for televisions with only a 75-ohm RF coaxial input)
• Separate antenna/cable TV input. (eliminates the need for switching cables back and forth)
• Channel 3 or 4 output selector switch. (ensures compatibility with most televisions)
• Auto sensing A/B switch. (automatically switches back and forth between antenna and video source)
