5.3 Getting to Know Your VS-55V Switcher
The Kramer VS-55V is a high performance 5x1 vertical interval switcher designed for composite video
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 common
reference sync. The LINK connector is designed to allow the use of a VS-55A to form “audio-follow-
video” systems. The VS-55V also provides an EXT connector, which allows several 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 RK-50R kit that holds two units in one or two vertical rack spaces.
