The Kramer VS-1211, VS-1011, VS-811, VS-611, and VS-411 are a family of high performance vertical interval switchers for composite video and balanced audio stereo signals. One of 12 sources can be routed to one monitor, VCR, or other receiving device. Since switching is performed during the vertical interval, transitions are glitch-free when sources share a common reference sync. There are a total of four ways to control the VS-1211 family: front-panel buttons, RS-232, RS-485, and contact closure. They are also designed to be easily expandable for larger switching systems.
For example, two VS-1211s can be combined to form a 24x1, etc. Multiple units can also be operated in parallel for switching component signal formats. For example, two VS-1211s could be linked to form a 12x1 switch for Y/C, three could be linked to switch YUV, etc.
