HDBaseT™ 4K UHD Receiver, featuring audio de-embed and ARC/Optical audio return (4K: 70m/230ft | 1080p: 100m/328ft)


Free the audio from SmartTV on-demand content with the RX-70-4K-ARC HDBaseT™ receiver supporting ARC or optical audio return to enable digital audio to be sent back to a compatible WyreStorm HDBaseT™ transmission device, such as an H2 model matrix switcher.



Audio Return Technology

The RX-70-4K-ARC can transmit multi-channel digital audio from the TV location back to the transmitter device for connection to an amplifier.

Audio de-embed

Optical & coaxial S/PDIF output allows for extraction of source audio from HDBaseT™ signal.

HDMI & Optical Options

Audio Return selectable between HDMI or S/PDIF optical input which allows for audio from a TV without ARC support to send audio to the transmitter or matrix.
