XCU Universe XF Transmission
4K and 6X HD Base Station

Grass Valley XCU Universe XF base stations have been developed to support the extended bandwidth requirements of LDX 86 Series high-speed cameras with up to 6X speed operation, 4K-capable cameras and 15 F-stops of high dynamic range (HDR) in 1X speed operation. They are the latest members of the XCU range of camera base stations and share the same unique cradle concept with the other XCUs that are available for the LDX 80 Series of cameras. The future-ready cradle concept supports the broadcast requirements of today and tomorrow.

With high bandwidth IP networks becoming more and more available for live productions, the new XF Transmission Direct IP Interface eLicense enables a direct IP interface of the complete transmission protocol between the cameras and XCUs over IP networks.

LDX 2016 Cameras Catalog Datasheet

LDX 86N Series (Fully Native HD/3G/4K/High-Speed)

The LDX 86N Series is the latest addition to the LDX Series, delivering native HD, 3G and 4K images for the highest possible resolution and image clarity. The LDX 86N Series lets you grow into the formats you need tomorrow while buying only what you need today. With a daily, weekly or perpetual GV-eLicense upgrade path, you can move from any single speed HD/3G format to 4K — from 3X HD speed to 6X HD/3X 3G speed — and even a camera that can switch between higher resolution and higher frame rate.

LDX 86 Series High Sensitive (HD/3G/4K/High-Speed)

The LDX 86 Series of cameras offer the perfect solution for all format requirements, especially when light sensitivity is of prime importance. Acquiring in native 1920x1080, the LDX 86 4K and LDX 86 Universe cameras use a unique closed-system process for 3840x2160 UHD where all of the processing takes place within the camera system. This delivers a 4K image with the highest light sensitivity available in any system camera, with images almost indistinguishable from native 4K acquisition in most applications.

LDX C86 Compact HiSpeed 3X (HD/3G) and LDX C86 Compact XtremeSpeed 6X (HD) Cameras

The world's first self-contained high-speed cameras in a small form factor for space-constrained applications. As an extension to the LDX range of cameras, they produce the same level of quality from angles and in areas where high-speed cameras with a compact form factor are required.

LDX 80 Series (HD/3G)

A unique line of advanced imaging cameras built around Xensium-FT CMOS imagers. These cameras have the highest sensitivity and image performance across different video formats, while offering a new level of business flexibility by using one hardware platform with a flexible GV-eLicense software upgrade implementation.

LDX C80 Compact Series (HD/3G)

An extension to the LDX Series of cameras with an identical image performance and a comparable feature set but in a smaller mechanical package. They are the perfect companions to the LDX Series cameras and bring a new level of image performance and business flexibility for all applications where cameras with a compact form factor are required.
