The ARC feature eliminates the need to use an additional composite audio cable or an optical cable when connecting an Audio/Video (A/V) receiver or surround sound system to a TV. Connecting an HDMI cable from an ARC-compatible A/V receiver to an ARC-compatible TV will allow the following:
- Send audio to the A/V receiver from the TV.
- View and listen to movies and other content from source devices as they are passed through the A/V receiver to view on the TV.
The following image displays the connections required to get sound from a TV that is ARC compatible to an audio unit that is also ARC compatible:
[B]: Audio system
[C]: HDMI ARC input on the TV
[D]: HDMI ARC output on the Audio system
[E]: HDMI cable (high quality, high-speed HDMI cable)
NOTE: Low quality HDMI cables that are not labeled high-speed will not be able to provide the ARC function.
