About the Audio and Video Switchers
The Extron SW family of audio/video switchers are 6-input,
2-output composite video, S-video, and/or stereo audio
switchers. The AS and Auto versions are functionally identical,
but also include an auto-sync detect mode. Auto-sync detect
mode, when enabled, automatically selects the highest
numbered input with a video signal available. The following
table identifies the models and their video, audio, and auto-sync
capabilities.

Composite video
The switchers are compatible with NTSC, PAL, and SECAM
video. If external sync is connected, video switching occurs
during the vertical interval, providing glitch-free switching.
The switchers allow the user to switch between devices, such as
a DSS receiver, a VHS or S-VHS VCR, a DVD player, or a
camcorder and output the image to one or two video recorders
or displays such as a data monitor or large screen projector
(figure 1-1).
The ½-rack width switcher can be mounted to a standard Extron
rack panel (part # 60-190-01). Each model has an internal
100VAC to 240VAC, 50/60 Hz, 10 watts, auto-switchable power
supply that provides worldwide power compatibility.
