Kramer 4X1VB
4x1 Mechanical Video Switcher


The Kramer 4x1VB is a high quality 4x1 mechanical switcher designed for composite video signals using BNC connectors. It accepts up to four inputs and allows the user to select any input to be routed to one output using buttons located on the side panel. High quality switching components are used to ensure minimal crosstalk and very high bandwidth. The entirely passive design of the 4x1VB eliminates the need for a power supply.
