INTRODUCTION
The MA-5544V 4K-HDR 4x4 HDBaseT Lite matrix with PoC provides the most flexible and cost
effective solution in the market to route high definition 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. MA-5544V
supports all 3D formats, the true 4K 2K video and provides one HDMI local loopout. Through only one low
cost Cat-5/5e/6 LAN cables, not only high quality video and audio can be transmitted to the display sites,
but also users can switch among four HDMI sources using the push button, IR remote, RS-232, IPcontrol,
web-interface control, cloud, control 4 & Alexsa Echo control. Furthermore, the built-in IR extension
function makes users at display site access the DVD player, PS4 or any HDMI supported devices directly!
In addition, MA-5544V also supports PoC (Power over Cable) which can power RX unit from TX side with
power supply.

The length depends on the characteristics and quality of the cables. Higher resolutions and
longer transmission distances require low skew cables (<25ns/100m) for best performance.
Unshielded CAT6 with metal RJ45 connectors is recommended.
1. HDR = High Dynamic Range.
2. The video bandwidth of 4K2K@60 4:2:0 10bits (HDR) is 384 MHz, and the 4K2K@60 4:4:4 8bits
is 594MHz.
3. When used in conjunction with the EX-57VAC-I-SP-RX receiver
(a) The MA-5544V can support resolution downscaling from 4K2K to 1080P
(b) NOT supports resolution downscaling from 4K2K@60 4:2:2 to 1080P
