Rear Panel
● LAN (10M/100M) and RS232 are for PC control.
● Analog Audio IN/OUT ports bind to their corresponding HDMI ports by default.
For example:
If HDMI 1 audio source is selected with External LR, then analog AUDIO IN LR1 (with
phoenix connector) will be selected to replace the embedded audio of the HDMI
input 1 data stream. If HDMI 1 audio source is selected as AUTO by PC TOOL or
command, then the original embedded audio of input HDMI 1 will be used as its
audio data stream. If the input is DVI signal, no matter how it is set up, the system
will get the external analog audio input. Analog AUDIO OUT n will always output the
same audio content with HDMI OUTPUT n.
● IR IN and IR OUT
IR IN/OUT routing follows the video matrix routing. There is no need to separately
control the IR matrix.
