The Extron SW HDMI LC Series are two and four input, one output, high-definition multimedia interface (HDMI) switchers
that allow multiple HDMI signals, including digital video and embedded multi-channel digital audio to be switched to one
compatible output. These switchers support all standard single link HDMI 1.3a (up to 225 MHz) and DVI 1.0 signal formats
and are compatible with all HDTV resolutions up to 1080p and computer resolutions up to 1920x1200, at 60 Hz with 12-bit
color. This guide provides basic instructions for an experienced installer to set up and operate these switchers.
