Atlona Technologies AT-HD19SS 1x9 HDMI™ splitter is the perfect solution for those who want to
display a single source on 9 or more displays using just single Cat5 or Cat6 cable for each
display. The Atlona splitter has 8 x RJ45 (Cat5/Cat6), one for each display and 1 x HDMI™ output
to be used for local monitoring or a loop-out for cascading multiple splitters. AT-HD19SS is
capable of HDTV resolutions up to: 1080p@130ft and 1080i@200ft.
Note: A receiver unit (balun) is required for each display and sold separately (Model: AT-HDRS or AT-
HD15SRS).

For shorter transmission length, AT-HD15SRS is more recommended instead of AT-HDRS.
