Specifications

OREI  ARC-EX300-K  HDMI ARC & S/PDIF Audio Extender - 500ft.

The ARC-EX300-K is a compact HDMI ARC and S/PDIF audio extender designed to deliver high-fidelity audio transmission over long distances. Capable of extending HDMI ARC signals up to 492 feet (150 meters) at 96kHz or 295 feet (90 meters) at 192kHz over a single CAT cable, it offers a reliable, plug-and-play solution for routing audio from a TV back to an amplifier, AVR, or multi-room audio system.

For TVs without an ARC port, the device includes a dedicated S/PDIF audio pass-through channel, transmitting audio from the S/PDIF IN port on the transmitter to the S/PDIF OUT port on the receiver.

CEC pass-through is also supported when operating in HDMI ARC mode, allowing seamless control integration between connected devices. With ultra-low jitter and precision-engineered signal design, the ARC-EX300-K ensures uncompromised audio performance in both residential and professional AV installations.
