The C2YC converter accepts Composite video and splits the signal into the Luminance "Y" and the Chroma "C" components or S-VHS (S-Video). Send a Composite video signal to the Video Input connector (BNC) on the rear panel. The separated "Y" and "C" video signals are obtained from the "Y/C Output" connector on the rear panel. The "Y" and "C" output is 75 Ohms and utilizes a standard 4 pin S-Video din connection.
