INTRODUCTION
The MA-5244C 4x4 HDMI Deep Color & full 3D over single Cat.X matrix 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 only one low cost Cat-5/5e/6 LAN cable, 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. Furthermore, the built-in IR extension function makes users at display site access the
DVD player, PS3 or any HDMI supported devices directly!

EDID LEARNING
The EDID learning function is only necessary whenever you encounter any display on the HDMI
output port that cannot play audio and video properly. Because the HDMI source devices and displays
may have various level of capability in playing audio and video, the general principle is that the source
device will output the lowest standards in audio format and video resolutions to be commonly acceptable
among all HDMI displays. In this case, a 720p stereo HDMI signal output would be probably the safest
choice. Nevertheless, the user can force the matrix to learn the EDID of the lowest capable HDMI display
among others to make sure all displays are capable to play the HDMI signals normally.
There are THREE methods to do EDID Learning as below,
1. Front Panel Push-in Button: Please refer to the Operation Approach\ Method A: Push-in Button
(Page 8)
2. IR Remote Control: Please refer to the Operation Approach\ Method B: IR Remote Control (Page
10.)
3. Software Control: Please refer to the Operation Approach\ Method C: Software Control through
RS-232 port (Page 13.)
There are eight embedded default EDID as below,
1. Full-HD([email protected])-24bit 2D & 2ch
2. Full-HD([email protected])-24bit 2D & 7.1ch
3. Full-HD([email protected])-24bit 3D & 2ch
4. Full-HD([email protected])-24bit 3D & 7.1ch
5. HD([email protected])([email protected])-24bit 2D & 2ch
6. HD([email protected])([email protected])-24bit 2D & 7.1ch

FAQ
The quality of output video is not good enough, how can I do?
Please adjust the 8-level equalization on the receiver units. The HDMI signal level varies from 0
(strongest) to 7 (weakest) for respective transmission length from longest possible range to short
distance. It is recommended to switch from 7 to 0 to find the optimal visual experience.
Can I use any kind of LAN cable?
Please check the NOTICE section for more information about how to pick up a suitable cable.
Can every TV work with the HDMI matrix?
Basically, the answer is YES. But if your TV can not support 1080p, please refer the EDID
LEARNING section to learn EDID from your TV.
What is EDID? Why do I need to learn EDID?
EDID contains the whole information of the display such as the resolution and audio setting which
this display can support. Therefore, based on the EDID information, media player will pick up the
most suitable resolution and audio setting to the display. In order to faithfully transmit the EDID
information from display to the media player, learning EDID from display to this device is
necessary.
What should I do to learn EDID for the matrix?
Due to the limitation of HDMI, the source device can only output one format of video and audio. In
other words, the source device cannot output 720p and 1080p video at the same time, or output
stereo and surround sound at the same time. Therefore, you may need to manually setup each
HDMI input for desirable audio/video output format. The mechanism of EDID Learning is to pick up
the HDMI display with the lowest capability among the ones you would use for this input source.
For example, if user would like to play the Input-2 upon output-2, output-3 and output-4, and only
output-3 cannot support 1080p [support up to 720p only], please learn the EDID from the display
connected to the output-3 at the Input-2 port. Of course, if outpt-3 would get the HDMI signals from
every HDMI input, please learn EDID information from output3 to all four HDMI inputs. For more
information about EDID Learning, please refer to EDID LEARNING section.
19
My TV can support 1080p, but why there is no audio?
The factory default EDID of this device is 1080p & 2ch audio. However, there would be a problem
after you change to use 1080p & 7.1ch if the TV cannot support 7.1ch audio. Please use the
default EDID, 1080p & 2ch audio.
When I set an audio amplifier (AV receiver) between TV and the matrix to extract 7.1ch
audio, but why there is still no audio?
Basically, the default EDID of the chosen input can support 7.1ch audio, but the problem is that the
EDID of the amplifier still cannot match the default setting. Therefore, the best method is to learn
EDID from the amplifier directly. Please refer to EDID LEARNING section and follow the steps to
learn the EDID. When learning EDID from the amplifier, user just needs to connect the matrix and
amplifier. Please don't connect HDMI cable between amplifier and TV when the EDID
learning is proceeding.
When I play the same content upon multi-displays, why only the TV equipped with amplifier
can have 7.1ch audio, and the others don't have 7.1ch audio even no stereo?
Due to the limitation of HDMI, the source only can choose one video and one audio format to play,
which can be either 1080p and 7.1ch or 1080p and stereo audio. It means when the user sets the
matrix at 1080p and 7.1ch, the source will only play the content under this format. Therefore if the
TV cannot decode 7.1ch audio, there is definitely no audio.

NOTICE
1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to retrieve
and provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz LAN
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
3. The transmission length is largely affected by the type of LAN cables, the type of DVI sources, and the
type of DVI display. The testing result shows solid LAN cables (usually in bulk cable 300m/1000ft form)
can transmit a lot longer signals than stranded LAN cables (usually in patch cord form). Shielded STP
cables are better suited than unshielded UTP cables. A solid UTP CAT5e cable shows longer
transmission range than stranded STP CAT6 cable. For long extension users, solid LAN cables are
the only viable choice.
4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, one can use
shielded LAN cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the LAN cables has the major effect on how long the transmission limit can
achieve and how good is the received picture quality, the actual transmission range is subject to one’s
choice of LAN cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-6 cable is
recommended.
7. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]
generally can produce better transmission performance among all HDMI inputs.
8. Additional IR remote controls and IR blasters can be purchased as optional accessories to control the
HDMI sources located separately.
