It is an innovative HDMI 2.0 extender with eARC & ARC functions, which allows users to transmit 4K@60Hz (4:4:4) HDMI signal up to 40m/131ft over a single Cat 6a/7 cable.

Immersive Audio Experience with eARC

“More and more consumers want to return the best audio from their smart TV to a remote AV receiver, like uncompressed 7.1, Dolby Atmos, DTS:X.
