The HDMI ARC (Audio Return Channel) function allows you to send audio from
your ARC-compliant TV to ARC-compliant audio devices (e.g. home theatre)
through a single HDMI connection.
With the HDMI ARC connection, you do not need to connect the extra audio
cable that sends the sound of the TV picture to the ARC-compliant audio
devices. The HDMI ARC connection combines both signals.
Use an HDMI cable (not included) that supports the ARC function to connect
your ARC-compliant audio devices with your ARC-compliant TV.
