Kramer VM-8UX Data Sheet

VM-8UX

1:8 4K 12G SDI DA

VM−8UX is a compact and high performance 1:8 4K
distributor for standard broadcast−grade SDI signals
of up to 12G transmitted data rate. It auto−adapts to
data rate of one SDI input signal, equalizes and
re−clocks the signal to improve transmitted signal
reach, and distributes the signal to eight identical SDI
outputs

FEATURES

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 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 (260ft) 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 rates
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

Max. Resolution-4K@60Hz (4:2:2) 30bpp
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
