| Extron VSW 2VGA A Two Input VGA and Stereo Audio Switcher |
Product Code: VSW2VGAA
 |
The Extron VSW 2VGA A is a compact and
economical two input, one output, active switcher for VGA and stereo audio. It
allows users to select between two VGA sources with audio and route the selected
source to a video output device such as a data monitor or projector. In
addition, the VSW 2VGA A provides a buffered local monitor output for input one.
Multiple VSW 2VGA A switchers can be daisy-chained using Extron high performance
pre-fabricated VGA cable to create a multi-user presentation system.
The VSW 2VGA A switches a variety of analog video signals at VGA-QXGA
resolutions, including RGBHV, RGBS, RGsB, RGBHVS, and other high resolution
computer video signals. Multiple forms of control are provided, including
front-panel buttons, contact closure, and auto-input switching. In auto-input
switch mode, input sources are selected automatically when the switcher detects
an active sync signal, making the VSW 2VGA A ideal for automatic routing and
unattended operation.
The VSW 2VGA A is housed in a quarter rack width metal enclosure, and its
flexible mounting options make it ideal for integration into conference rooms,
classrooms, multimedia production systems, and other high resolution, computer
video environments. |
