⚫LAN (10M/100M), RS232 are for PC control
⚫Analog Audio IN/OUT ports bind to corresponding HDMI ports.
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 with AUTO by PC TOOL or command, then will use the original embedded audio of input HDMI
1 as its audio data stream.
If the input is DVI signal, no matter how it is set up, system will get external analog audio input. Analog
AUDIO OUT n will always output the same audio content with HDMI OUTPUT n Analog Audio IN/OUT
connection
⚫IR IN and IR OUT
IR IN/OUT routing follows video matrix routing, no need to separately control IR matrix
IR extender connectors (not as accessories)
⚫Audio Input
4 3-way Phoenix connectors to input external analog LR audio, user can select this audio to replace
the corresponding embedded HDMI audio
⚫Audio Output
