Using the Audio Return Channel (ARC)
The Audio Return Channel (ARC) allows audio to be sent upstream, from the display device, to the AT-JUNO-451-
HDBT over an HDMI cable. The audio is then output over the OPTICAL port. This technique can be used to send
audio from a Smart TV, using an app such as Netflix
®
, to an A/V receiver, providing a multichannel audio experience.
The advantage of ARC is that no additional audio cables are required to be connected between the display and the
audio output device.
The illustration below, shows an example of how the Audio Return Channel works. The dark green lines identify the
audio coming from the display. The instructions on the following page will reference the diagram below.
