## Long description

The Kramer Electronics VM-4UX is a compact 1:4 4K SDI distributor and line amplifier that auto-adapts to the input SDI data rate, equalizes and re-clocks the signal, and delivers four identical SDI outputs. It supports broadcast-grade coaxial connections via lockable BNC connectors and is designed for professional AV and broadcast installations requiring reliable uncompressed SDI signal distribution up to 12G data rates.
Advantages
The unit provides reliable wire connectivity using lockable BNCs to prevent accidental disconnection and ensure stable signal distribution. Built-in input equalization and output reclocking extend transmitted signal reach and improve signal integrity. The VM-4UX auto-adapts over a wide transmitted data rate range (270 Mbps to 12 Gbps) and complies with SMPTE and ST standards for SD, HD and 4K SDI. Status LEDs for input, output data rates and power simplify maintenance and troubleshooting. Its compact, fan-less DigiTOOLS enclosure enables flexible installation including over-ceiling or side-by-side rack mounting.
