The Model VS4-YC is a versatile S-Video (Y/C or S-VHS) Switch with 4 inputs and one output. It is compatible with all TV standards.
The selection of the channel to be displayed can be made from individual front panel switches or via RS-232 control port. Four LED lights are used to show the channel selection.
The unit features 250 MHz amplifiers for a clear and crisp image and also buffers the audio signals with low noise amplifiers for a distortion-free sound.
The output can be placed in scan mode (either from the front panel by pressing two buttons simultaneously, or via a serial command). In this mode the output displays each input channel for a few seconds and cycles through all inputs. The output can also be blanked (with audio muted) via a serial command.
