Extron electronics SW HDMI LC Series User manual

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.
