eARC/ARC Applications
The Audio Return Channel (ARC) in HDMI 2.1 enables a display, via a single HDMI
cable or audio cable, to send audio data “upstream” to an A/V receiver. The
BG-EXH-8KC6 will send the upstream audio from the receiver (RX) unit to the
transmitter (TX) where it can be connected to a compatible device via HDMI ARC.
Note: Press the eARC buttons on the front panel of the transmitter and receiver to
enable the eARC/ARC functions before trying to operate the system.
