Audio Return Channel (ARC)
ARC enables a source connected to a display to route audio back to the
switcher and send the de-embedded audio out the S/PDIF output.
Steps
1. Check to be sure the display supports ARC
2. Enable ARC on the HDMI output of the switcher through RS-232
(command ARC on), TCP/IP, or webGUI
3. Connect the HDMI output port of the switcher to the ARC labeled
input port on the display
Note: The switcher must be connected to the display's HDMI ARC input
Note: Works well with audio from ARC enabled "Smart" televisions
4. Connect the source to a non ARC HDMI input port on the display
5. Connect the S/PDIF port to an AVR or Zone Amp
