9. ARC Mode
Audio Return Channel (ARC) allows audio from a display to pass “upstream” through
an HDMI cable to an audio processing device, such as an AV amplifier. When ARC
mode is active on the switcher, the ARC stream will pass to the active HDMI source
device if it can process the signal.
Only the fourth HDMI input port features ARC, when the display and AV amplifier
support ARC, the audio connection diagram is shown below:
