Kramer VM-4UX 1:4 4K SDI Distribution Amplifier

Overview
The VM-4UX is a 1:4 4K distributor that can handle up to 12Gbps of data rate and supports resolutions up to 4K (4:2:2) 30bpp. It is compliant with SMPTE standards and has lockable BNC connectors for reliable wire connectivity. The distributor also has the ability to equalize and re-clock the signal for extended reach, with support for up to 80m (260ft) at 12Gbps.

It can handle various types of SDI signals including SD, HD, 3G, 6G, and 12G, and has LED indicators for easy monitoring of signal data rates and power status. The compact and fan-less design makes it easy to install in small spaces or in a rack. With its high performance and professional features, the VM-4UX is a reliable choice for distributing SDI signals.

About the Kramer VM-4UX 1:4 4K SDI Distribution Amplifier
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, equalises and re−clocks the signal to improve transmitted signal reach, and distributes the signal to four identical SDI outputs.

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 equalisation 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.

Compliance — Complies with SMPTE 259M (SD–SDI), 292M (HD–SDI), 344M (ED–SDI), 424M (3G HD–SDI), ST–2081 (6G–SDI) and ST–2082 (12G–SDI) standards.

SDI Signal Transmission — SDI, HD–SDI, 3G HD–SDI, 6G and 12G SDI compliant signals, supporting pass–through of standard embedded audio channels with ancillary ID and metadata information.

LED Indicators — Status indicators for transmitted SDI data rate of input and output connected signals, and power indicator, for ease of maintenance and troubleshooting.

Easy Installation — Compact DigiTOOLS™ fan–less enclosure for small footprint spaces and over–ceiling mounting, or side–by–side rack mounting.
