Description

The VM-4UX is a compact and high performance 1:4 4K distributor for standard broadcast-grade SDI signals of up to 12G transmitted data rate. It auto-adapts to the data rate of one SDI input signal, equalizes and re-clocks the signal to improve transmitted signal reach, and distributes the signal to four identical SDI outputs. Manufacturer part number VM-4UX.

Key features

Reliable Wire Connectivity - Coaxial broadcast-grade cables are

Reliable Wire Connectivity - Coaxial broadcast-grade cables are reliably connected via lockable BNC connectors, preventing unintentional wire disconnections, to gain fast and highly professional uncompressed SDI signals distribution deployments.

Extended-reach Input Extension - Input signal equalization and output

Extended-reach Input Extension - Input signal equalization and output signals reclocking to gain extended-reach signal extension. Using Kramer high-quality coaxial SDI cables, supports extension of up to 300m (984ft) for SD signals; 200m (656ft) for 1.5G HD signals; 100m (328ft) for 3G and 6G HD signals; 80m (262ft) for 12G 4K signals. Note: Reach depends on signal resolution, and quality of copper cable used. Reach extension performance may vary while using non-Kramer coaxial cables.

Transmitted Data Rate - Auto-adapting from 270Mbps to 12Gbps data
