The model MT105-111 is a 8 X 8 Sync Matrix Switcher Card. The MultiTasker® Mid-Sized Video Matrix Switcher Series (MT MVMS) is a line of video matrix switcher cards designed for use in MultiTasker enclosures to allow the routing of computer and broadcast video in audio/visual presentation systems. The MT MVMS Series provides a solution for many medium-sized configurations, and is particularly well-suited for high tech boardroom/conference room installations. Inputs are selected via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of a MultiTasker enclosure. It is designed to accommodate the special impedance requirements of the "H" and "V" Sync channels, or the "S" channel of RGBS systems.
