SW1-SW2for EDID/Audio
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.
