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.

Features
S-video models
Inputs — S-video switchers accept up to six S-video inputs on
4-pin mini DIN connectors.
Outputs — S-video switchers output two identical S-video
signals on 4-pin mini DIN connectors.
Composite video models
Inputs — Composite video switchers accept up to six composite
video inputs on BNC female connectors.
Outputs — Composite video switchers output two identical
composite video signals on BNC female connectors.
Audio models
Inputs — Audio switchers accept up to six stereo audio inputs,
balanced or unbalanced, on 3.5 mm, 5-pole captive screw
terminals.
Outputs — Audio switchers output two identical stereo audio
outputs, balanced or unbalanced, on 3.5 mm, 5-pole
captive screw terminals.
Audio input gain and attenuation — Users can set the level of
audio gain or attenuation (-15dB to +9dB) for each input
via the RS-232 link or from the front panel. Individual
input audio levels can be adjusted so there are no
noticeable volume differences between sources.
