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 is capable of switching a variety of analog video signals, including RGBHV,
RGBS, RGsB, and RGBHVS, as well as VGA–QXGA, Macintosh®, and other high resolution
computer video signals. In autoswitch 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 high performance VSW 2VGA A can be controlled via its front panel toggle switch or contact
closure. Housed in a quarter rack width metal enclosure with flexible mounting options, the
VSW 2VGA A is well suited for conference rooms, classrooms, multimedia production systems,
and other high resolution, computer video environments.
