This Audio Extender can extend the transmission distance of both HDMI eARC and S/PDIF audio signals up to 100m328/ft over a single CAT6 cable. It supports CEC pass-through between HDMI eARC input port and eARC output port to handshake for eARC audio transmission. For TVs without HDMI eARC function, this audio extender provides an additional SPDIF audio pass-through channel to transmit SPDIF audio from the SPDIF IN port of the transmitter to the SPDIF OUT port of the receiver.
it can achieve zero-delay, uncompressed long-distance audio transmission between the transmitter and receiver. This is a fantastic plug and play solution for transmitting HDMI eARC and SPDIF audio from an HDTV back to an amplifier, AVR or multi-room audio system.
