Kramer Electronics VS-44DT 4x4 4K HDMI a HDBaseT matrix switcher s PoE, RS-232 a rackovými ušami

Managing multiple HDMI sources across several displays can quickly become a cabling nightmare, but the Kramer VS-44DT solves this by routing any of four HDMI inputs to any of four HDBaseT outputs over a single Cat6 cable. It supports 4K@60Hz (4:2:0) video, HDCP 2.2, and provides Power over Ethernet to compatible receivers, eliminating the need for local power at each display. This 1U half-rack unit includes rack ears and advanced control options, making it ideal for conference rooms, classrooms, and digital signage.

Who is it for

System integrators, AV professionals, and IT managers who need a reliable, long-distance HDMI distribution solution for multi-display environments. It is perfect for corporate boardrooms, educational facilities, houses of worship, and retail spaces where centralised control and clean installations are priorities.

Main features

Tips

For best performance, use shielded Cat6 (or higher) cables and ensure all HDBaseT receivers support PoE if you plan to use that feature. The analog audio outputs can feed a separate amplifier or mixer, giving you flexibility in audio routing. Always update firmware via the USB port to maintain compatibility with the latest sources and displays.
