eARC mode
If [Auto] is selected, high quality audio is output when an eARC supported device is connected to
an HDMI port labeled “eARC/ARC”. eARC is an extended version of ARC and stands for
Enhanced Audio Return Channel. By connecting an eARC supported device, you can enjoy
uncompressed, high-quality audio formats and newer surround audio formats in addition to the
audio formats supported by ARC connections thus far. For audio formats supported by eARC,
refer to Pass-through audio formats supported with eARC.
To connect the TV and an eARC supported device, use an eARC-supporting HDMI cable . To
connect an eARC supported device, refer to Connecting an audio system.
Sony's Premium High Speed HDMI Cable(s) is recommended.

quality is superior compared to analog connections.

technology.
