4K HDBaseT HDMI™ Extender (ARC, LAN & KVM) - 330ft (cat6)-UHD-EXB330AUR-K

Extender with ARC

Just installed these to replace Altona units that quit working. Wanted to replace the old ones anyway because they didn’t have ARC capability. So far these are working great. ARC is working to pass surround audio from streaming apps on Samsung TV to Marantz receiver and the video looks good going from the receiver inputs to the TV. IR is working as well, though I wish I could attach more than one output to control the different devices in the AV closet. There is probably a splitter or multi headed transmitter I could buy.

Failed after two days.

Stopped working after two days. Resetting the devices made no difference-dead. Tech support and sales don’t answer their phones. Sent back for a refund. Don’t waste your time and money.
