Note
1
If the HDTV shows video but without audio, please try to set audio mode to stereo.
2
Factory default of SW1-SW2: Pin#1-OFF [] & Pin#2- OFF [] for 1080p with stereo.
3
If you encounter any unsolved audio/video output problem during system installation,
please turn any SW1-SW2 to Pin#1-OFF [] & Pin#1-ON [] , for safe mode to enforce the
most compatible 720p stereo output 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.
4
Bypass 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 change the DIP switch setting to
default mode or even safe mode to verify the functionality of the device.
5
Set Pin#1 at ON [] first then connect the HDMI Input to HDTV through a HDMI cable. Wait
for 20 seconds. The EDID learning procedure will be finished. If you want to learn the EDID
from another HDTV, you must set Pin#1 at OFF [] first and repeat this procedure.

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 by performing the procedures stated below.
SW1 / SW2’s pin 1 must be set at ON for EDID Learning Mode

EDID Learning

~ 11 ~
1. Power up the matrix master unit. Connect the HDMI display that its EDID needs to be learned
to either/both of the HDMI INPUT 1 & INPUT 2 port where your source device has trouble to
show the picture normally.
2. To learn the display’s EDID for source device connected to respective HDMI INPUT 1-INPUT 2
port, pull both pins of respective DIP switch SW1-SW2 up-and-down to stay at on-on [-]
and wait for about 5 seconds to complete the EDID learning process. You DON’T NEED to pull
up the DIP switch again unless you want to learn another display’s EDID by pulling both DIP
switch pin 1 & pin 2 of SW1 / SW2 up-and-down one more time.
3. Repeat step1 & step2 if you want to learn the EDID of this HDMI display on any other HDMI
input ports that have same trouble playing the audio/video properly.
Method A: Push Button
Push the red switch button of the output port to select the input channels.
Method B: IR Remote Control
a. Choose the output port you want to make channel
switch from OUT 1 to OUT 4 then press 1 or 2 channel
button to choose the HDMI input source shown on the
chosen output display.

this Device ID.
Linkage: Indicate the connection status.
Open: Open the COM port after scan to establish the connection between PC and the matrix.
Close: Release the COM port after scan.
Mapping: Click on this button, a quick selection table of inputs will show up. Users can
therefore easily select the output video for each input by pressing “Output” button.
Fast Select: Provide the fast setup between inputs and outputs of the matrix. “Input1 – All
Output” means all four outputs playing HDMI input 1. “Input2 – All Output” means all
four outputs playing HDMI input 2.
