Audio Return Channel (ARC)
KD-Pro8x8D supports Audio Return Channel. When enabled, audio from the connected display is
returned to the matrix and output on KD-Pro8x8D’s audio de-embed ports.
ARC is useful in applications where an internet-enabled display is streaming content. ARC is a
means for the audio to still reach the distributed audio system or AV Receiver.
ARC must be enabled via IR, RS-232, or TCP/IP. After enabling ARC, the output’s digital and
analog audio connection will provide the audio returned from the display/output.
