VS-55YC 5x1 Vertical Interval s-Video Switcher 

The Kramer VS-55YC is a high performance 5x1 vertical interval switcher designed for s-Video (YC) signals. One of up to five sources can be routed to one monitor, projector, or other receiving device. Since it switches during the vertical interval, transitions are glitch-free when sources share a common reference sync. The LINK connector is designed to allow the use of a VS-55A to form “audio-follow-video” systems. The VS-55YC also provides  an EXT connector, which allows multiple units to be combined to form larger switching systems. For example, two units will form a 10x1, three will form a 15x1, etc. A 12VDC-power supply is included for typical operation but the optional model VA-50P can power up to six Kramer devices requiring 12VDC. All Kramer VM-50 and VS-55 series products can be rack-mounted using the model R kit which holds two units in two vertical rack spaces.
