Antiference Single Input CVBS AV Modulator is an electronic device that allows you to convert a composite video signal, also known as CVBS (Composite Video Baseband Signal), and an audio signal into a modulated RF (Radio Frequency) signal. The modulated signal can then be distributed over a coaxial cable and received by a TV or other device equipped with an RF tuner.

The Single Input CVBS AV Modulator typically has one input for the composite video signal and a separate input for the audio signal. It modulates the signals to a specific frequency that can be selected using the device's controls, usually in the VHF or UHF range, before being output via a coaxial cable.

Single Input CVBS AV Modulators are commonly used in commercial and industrial applications, such as in hotels, hospitals, and sports bars, where multiple video sources need to be distributed to multiple TVs using an existing coaxial cable network. They are also used in residential settings where an older TV with only an RF tuner needs to receive a video signal from a newer device with composite video output.

Single Input CVBS AV Modulators are valued for their simplicity and cost-effectiveness, as they allow a single video source to be distributed to multiple displays without the need for expensive distribution equipment or rewiring of the existing infrastructure.
