Channel Vision's VDA-12 is an audio and base-band video distribution amplifier. It can expand the RCA output socket of your AV equipment by incorporating an audio input and a video input, which are distributed to twelve audio/video outputs. A built -in clamp circuit was designed to eliminate up & down roll pictures. The VDA-12 offers optimal picture quality with the audio/video cascade outputs that feature automatic video impedance. Overall, the VDA-12 is especially useful for connecting audio/video components to RF modulators or multiple zones.
