The Comprehensive CVG-21RCA is a versatile 2x1 high resolution mechanical switcher that can be used for many different types of signals. The CVG-21RCA switches three identical channels simultaneously, so it may be used for composite video with 2 audio channels; for three independent composite video channels; for one composite and one Y/C channel; for component video (YUV or RGB), SDI, HDTV or for any other combination. The CVG-21RCA uses an inchinchRFinchinch PCB design with three ultra high bandwidth channels, providing bandwidth exceeding 1000 MHz (1 GHz), and is therefore suitable for use with almost any common signal. It is housed in a desktop enclosure and can be used in inchinchreverseinchinch as well - functioning as a 1x2 switcher (toggling one source between two acceptors). It provides a simple solution for many switching needs and as the design is passive, it does not need power, thus increasing its versatility.
