Audio Return Channel (ARC)
Audio Return Channel (ARC) allows an HDMI source device that receives
content via air waves (such as a TV or STB connected to a satellite antenna) to
send audio “upstream” to your HDMI display devices using only one HDMI
cable.
Initial Setup
The VS482 supports dual HDMI output for dual view, such as two HDTV or
audio/video receiver (AVR) applications, as shown in the following diagram.
The audio/video coming from the HDMI sources (Blu-ray, DVD, etc.) are
received by the VS482 and then passed on to the HDMI displays (TV, projector
or AVR).
However if the HDMI audio or video is coming from the TV (through a
satellite antenna or STB), you can enable ARC so that audio is sent to the AVR/
HDMI receiver through the HDMI cable or the device(s) connected to the
audio output port(s). See p. 14 for the diagram.
Note: 1. Without ARC, you must connect another cable, specifically for
passing audio, from the TV to the AVR or the device(s) connected to
the audio output port(s).
2. The ARC function requires HDTV built-in ARC function and
connect to the correct HDMI output port. Check your HDTV’s user
manual for this information.
