Introduction 1 Introduction Welcome to Kramer Electronics (since 1981): a world of unique, creative and affordable solutions to the infinite range of problems that confront the video, audio and presentation professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 500-plus different models now appear in 8 Groups1, which are clearly defined by function.
Overview 3 Overview The VS-42HC is a true 4x2 matrix switcher for YUV (Y, Pb/Cb, Pr/Cr) component video and digital audio (S/PDIF) signals. The high quality VS-42HC lets you simultaneously route any of the 4 inputs to either one or both of the outputs. The component video and S/PDIF input and output signals are on RCA connectors, and the S/PDIF channel 2 is also available on optical (TOSLINK1) input/output connectors.
