Audio Return Channel (ARC) allows an HDMI display that receives or plays content via air
waves or Internet applications (such as a TV or STB connected to a satellite antenna) to send
audio “upstream” to your HDMI audio / video receiver using the same HDMI cable.
Initial Setup
The GHSW8242 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
GHSW8242 and then passed on to the HDMI displays / receiver (TV, projector or AVR).
However if the HDMI audio or video is coming from the TV (through a satellite antenna or
Internet Apps), you can enable ARC so that audio is sent to the AVR/HDMI receiver through
the existing HDMI cable or the device(s) connected to the audio output port(s). See p.11 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 to be connected to the correct
HDMI output port. Check your HDTV’s user manual for this information.
