Matrix Switch Corporation 'VGA Video Routing Switchers' have wide signal bandwidth combined with ultra-low crosstalk technology, producing artifact-free images at image resolutions up to QXGA. For applications that require either a very large number of inputs or very large number of outputs, Matrix Switch Corporation VGA routers can be cascaded with no degradation of overall performance. MSC-5-3208 routers can be cascaded to build systems with 128 VGA inputs and 8 VGA outputs in just 10RU (17.5" of vertical rack space). MSC-5-6416 routers can be cascaded up to 256 VGA inputs by 16 VGA outputs. And MSC-5-1664 can be cascaded up to 16 VGA inputs by 256 VGA outputs. These video routers can be combined with Matrix Switch Corporation's Analog Audio or AES Digital Audio routers, by connecting them with a D25 straight male to male through cable.
