ARC Solution
The coax digital audio port and the HDMI ports support ARC (Audio Return Channel) which
enables a display via a single audio/ HDMI cable to send (upstream) audio to amplifiers/
speakers, increasing user flexibility.
The transmitter provides an ARC switch on the bottom panel to enable ARC mode selection.
There are 2 modes in total, and connections will vary in different ARC modes to ensure normal
ARC output. See the chart below:

that does not support
ARC) to the HDMI input.

audio output to an audio
