ARC enables a source connected to a display to route audio to an AVR or zone amp.
The S/PDIF port is used for two audio options, ARC or matrix source audio de-embedding. When
using one, the other is disabled. By default the matrix comes with ARC turned off on all ports, this
enables the S/PDIF to de-embed audio from the matrix source. To switch between ARC and matrix
source audio, ARC must be turned on or off. Enable or disable ARC through RS-232 (see page 18)
or front panel (see below).
1. Check to be sure the display supports ARC
2. Enable ARC on the HDMI output of the matrix through RS-232 (see page 18) or front panel
(see steps above)
3. Connect the HDMI Matrix output port to the ARC labeled input port on the display
NOTE: The Matrix must be connected to the display’s HDMI ARC input
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
NOTE: The S/PDIF port used must be the same output number as the HDMI port connected
to the display
