The ALF-SUK4T is an 18 Gbps HDMI 1x4 HDBaseT splitter kit that distributes a single HDMI source to four displays through HDBaseT outputs, with an additional local HDMI loop output. It supports video resolutions up to 4K @ 60 Hz 4:4:4 and transmits HDMI signals over a single CAT 6 or CAT 7 cable up to 328 ft (100 m) at 4K resolution or 492 ft (150 m) at 1080p. Four HDBaseT receivers are included for connecting remote displays.
The kit supports video downscaling, allowing a 4K input signal to be converted to 1080p output where required. Its local HDMI loop output can be used for monitoring or cascading additional splitters to distribute signals to more displays. Audio de-embedding and EDID management provide additional flexibility for integrating the system into professional AV installations.
For system control and integration, the ALF-SUK4T supports IR pass-through, RS-232 control, and IR and RS-232 cascade control. Its 24V Power over Cable (PoC) feature allows the included HDBaseT receivers to receive power from the splitter over the HDBaseT connection, helping simplify installation.
