Introduction
About the Switchers
The Extron SW AV series (figure 1-1) is a family of video and/or audio switchers
with a wide array of input and output configurations, video formats, and audio
connections. The switchers route S-video (luminance (Y) and chrominance (C)),
and/or composite video, and/or unbalanced audio on RCA connectors, and/or
balanced or unbalanced audio on captive screw connectors. The table on the
following page lists the models and the combinations of inputs and outputs
available in the SW AV family.

Features
Video switchers
S-video (SV) models
Inputs — S-video switchers input 4, 6, 8, or 12 luminance and chrominance signals
on 4-pin mini DIN connectors.
Outputs — The selected S-video input is split, buffered, and output on 2
connectors.
• One S-video output on a 4-pin mini DIN connector.
• One encoded composite video output on a female BNC connector.
Bandwidth — Bandwidth is 250 MHz (-3dB). This high bandwidth allows the
switchers to switch all of the quad standard video formats with no loss of
signal quality.
Composite video (V) models
Inputs — Composite video switchers input up to 4, 6, 8 or 12 composite video
signals on female BNC connectors.
Outputs — The selected composite video input is split, buffered, and output on 2
female BNC connectors.
