VS4-YCA User’s Manual

 

1. Introduction 

 
1.1 General 

The Model VS4-YCA is a versatile S-Video (Y/C or S-VHS) Switch with 4 inputs and one output. It 
also switches stereo audio from each of the inputs. 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.
