INTRODUCTION
The AV-GM0783-S1 4x4 HDMI & Full 3D support over CAT5 Matrix with IR Pass-through
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. Through 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-in 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 supported devices
directly!
FEATURES
●Support HDMI Deep Color & full 3D
●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-in button, IR
remote control, or RS-232 control
●Allows controlling local HDMI sources such as DVD and TiVo by attached IR extender from
remote receiver to matrix master
●Allows to control matrix master through IR remote control at remote receiver’s site
●Extends video signal up to 35m (115 feet) over CAT5e at 1080p and likely longer with better HDMI
source device (such as PS3), better grade HDMI display (such as Sony X-series HDTV), and better
quality solid CAT6 cable
●Easy installation with rack-mounting and wall-mounting designs for master and receiver
respectively
●Fast response time –2~5 seconds for channel switch

turn any [SW1]-[SW4] to pin-1 at ON []& pin-2 at OFF []for safe mode to select the system
EDID up to 720p(1080i) video and stereo audio for system check. However, the safe mode
cannot be initiated if your HDMI source is set to enforce 1080p output. In this case, please
reconfigure your HDMI source to all resolution output for troubleshooting.
4Bypass means the matrix will maintain playing the original format of HDMI signals in video and
perhaps audio. By setting at this mode, the users may encounter compatibility issue among
different kinds of HDMI sources and displays. If you cannot get the audio and/or video output
normally at the system installation, please changethe DIP switch setting to defaultmode or even
safe mode to verify the functionality of the device.

input on the remote receiver MA-5144RX.
3. Connect each A/V SIGNAL output on the MA-5144 to respective A/V SIGNAL input on the remote
receiver MA-5144RX.
4. Connect IR blaster to the MA-5144 and direct the IR blaster to point towards the built-in IR
receiver of the HDMI source devices.
5. Connect the +5V 6A DC power supply to the MA-5144.
6. Power on all HDMI sources.
7. Power on the MA-5144.
MA-5144RX as receiver

2. Connect the A/V SIGNAL input on the MA-5144RX to the A/V SIGNAL output on the MA-5144.
3. Connect the CHANNEL CONTROL input on the MA-5144RX to the CHANNEL CONTROL output on
the MA-5144.
4. Connect IR receiver and place the IR receiver at the appropriate position that can receive the IR
signals sent from the users.
5. Dial the 8-level rotary control switch to adjust the HDMI signal level until the picture and sound
are clear. It is recommended to dial from 7 to 0 to find the optimal visual experience
You can buy any IR extension cables in the market that are compatible to the definition of
the IR sockets for the matrix if necessary for replacement use. However, IR cables longer
than 2m (6-ft) may not work.
