The VWP-SVA is a Composite, S-Video and Stereo Audio interface that fits in a single gang Decora style wall plate. The VWP provides an attractive connection point for VCR’s, DVD players, document cameras and much more. The VWP automatically selects the active composite or S-Video input, converting composite signals to S-Video. The selected signal in S-Video format is then passed through a line driver to allow cable runs of up to 300 feet. The unbalanced stereo audio input is converted to a balanced signal to get the highest audio quality. The stereo audio is balanced to help prevent interference.
