8-out V-MATRIX™ Video/Sync Output Cards

The VM2144VS/VM2145SS/VM2146UX are 8- output Cards designed for use in a V-Matrix™ enclosure and can handle a wide array of signal formats and connector types. When installed in a V-Matrix™ Basic Enclosure, these Output cards enable the connection of eight composite sources when used with the VM2143VS 8-in Video/Sync Input Card. See the VM2143VS for more information.

The VM2144VS/VM2145SS 8-output video/sync cards provide built-in ground loop isolation (GLI on Board™) through the use of differential inputs. This is an extremely important feature because it protects against hum bars and other interference caused by ground loops, which notoriously wreak havoc on large-scale matrix systems. Both the input and output video cards provide a bandwidth of 350 MHz @ –3dB, allowing them to pass extremely high-resolution computer video/sync signals without signal degradation.

The VM2145SS has a negative and positive polarity. It can be used as sync output by setting its jumpers to the appropriate position.

The VM2146UX is 8-output Universal Card that can process video and sync output signals. See jumper settings for sync and video output for more information.

All input and output cards are “hot-swappable” with finger adjustable lock-down screws and secure, positive engagement card-edge connections.
