VM2142AU

8-out V-MATRIX™ Audio Output Card

The VM2141AU is an 8-out Audio Output Card designed for use in a V-Matrix™ enclosure can handle a wide array of signal formats and connector types. When installed in a V-Matrix™ Basic Enclosure, these Audio Output cards enable the connection of eight audio sources. For inputs, the VM2142AU can be used with the VM2141AU 8- in Audio Input Card. See the VM2141AU for more information.

The 8-input video 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 signals without signal degradation.

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