The  ALF-MUH44E 18Gbps 4×4 HDBaseT Matrix can connect four HDMI sources to eight displays. It features four HDMI outputs, and each HDMI output is mirrored to provide a CAT Cable output that runs simultaneously. The HDBaseT output can extend video transmission distance up to 492ft / 150m (1080p) via a single Cat 6/7 cable, with resolutions up to 4K2K@60Hz 4:4:4. Audio de-embedded to analog and coaxial audio is supported. Each HDMI output supports 4K2K to 1080P downscale independently. The product supports IR matrix. The IR signal is one-to-one control at the Matrix end, and the IR signal follows the HDMI video channel at the HDBaseT Receiver end. The product provides an intuitive front panel with an OLED screen and control via front panel buttons and supports control via IR remote, RS-232, LAN, and Web GUI.
