LDK 4000 Elite

Single-Format HD Camera

The Grass Valley™ LDK 4000 Elite Single-Format camera is designed for small- to medium-sized broadcasters, digital production studios, and media-creation companies that have chosen a single high-definition (HD) format. It is available as either a 720p or 1080i camera head. It features low power consumption and Grass Valley's leading HD-DPM+™ technology that produces images unrivaled by any camera in the industry. Combined with Grass Valley frame transfer CCD technology, this ensures perfectly clean, low noise signals free from artifacts such as vertical smearing and aliasing. Dynamic anti-aliasing-on-sensor processing reduces artifacts. The LDK 4000 Elite also includes a secondary color corrector and user-selectable noise reducer. It is also based on a flexible HD transmission system, supporting standard triax as well as hybrid fiber SMPTE 311. A SuperXpander large lens adapter enables configuration with full size studio or mobile lenses as well as accessories.
