ARC Commands

Audio Return Channel (ARC) allows a source device (TV, STB, etc.) to send audio “upstream” to an audio/video receiver using only one HDMI cable. The formula for enabling/disabling ARC is as follows:

ARC Command + Control (On / Off) [Enter]

For example, to enable ARC, type the following:

arc on [enter]
