INTRODUCTION
The AT-HD44M-SR 4x4 HDMI over CAT5 Matrix with IR Control Path provides the most exible
and cost effective solution in the market to route high denition video sources plus multi-channel (up to 7.1-channel) digital audio from any of the four HDMI sources to the remote displays
at the same time. Through low cost CAT5/5e LAN cables, not only high quality video and audio
can be transmitted to the display sites, but also users can switch among 4 HDMI sources using
the push button or remote control. With single power design at the source site, each remote
module is easily installed without power supply. Furthermore, the built-in IR extension function
makes users at display site access the DVD player, PS3 or any HDMI equipped devices directly!
FEATURES:
• State-of-the-art Silicon Image (founder of HDMI) chipset embedded for upmost compatibility
and reliability
• HDMI 1.2a compliant
• HDCP compliant
• Allows any source to be displayed on multiple displays at the same time
• Allows any HDMI display to view any HDMI source at any time
• Supports 7.1 channel digital audio
• Supports default HDMI EDID and learns the EDID of displays
• The matrix master can switch every output channels to any HDMI inputs by push button, IR
remote control, or RS-232 control
• Allows controlling local HDMI sources such as DVD and TiVo by IR extender through control
path at remote receiver
• Allows to control main matrix center through control line at remote receiver
• Extends video signal up to 35m (115 feet) over CAT5e at 1080p
• Easy installation with rack-mounting and wall-mounting designs for master and receiver re-
spectively
