Product Introduction
Thanks for choosing the 18G HDMI Extender, which consists of a transmitter and a
receiver. It can extend 4K or 1080p video to distance up to 262 feet (80 meters) over a
single CAT6A cable without compression. It supports audio de-embedding and ARC. It
also supports bi-directional IR, USB and RS232 pass-through control and Ethernet
extension. 24V PoC feature allows the transmitter and the receiver can be powered
from each other and only one power adapter is needed in system.

System Connection
1) When ARC switch is selected to HDMI, and the TV supports ARC, the TV audio
can be transmitted back to the transmitter via HDMI output port of receiver, and
then it will be output by the ARC OUT & HDMI Source port of transmitter. CEC
pass-through is not supported in this mode.
2) When ARC switch is selected to SPDIF, the audio can be transmitted back to the
transmitter via ARC IN port of receiver, and then it will be output by the ARC OUT
& HDMI Source port of transmitter. Besides, it also supports CEC pass-through in
this mode.
3) When ARC switch is selected to PASS, the extender can pass the ARC signal and
support CEC pass-through. If the amplifier can work with the TV for ARC function,
the ARC audio can be transmitted back to the transmitter via HDMI output port of
receiver, and then it will be output by the ARC OUT & HDMI Source port of
transmitter.
Note: Please try to restart the extender if ARC function works abnormally.
