Recent Update: Now Includes a 12G/6G/3G/HD/SD Test Pattern Generator with 58 selectable output formats and 58 test patterns including Luma and Chroma Zone-PlatesThe Decimator 12G-CROSS is a compact HDMI and SDI 4K cross converter with scaling and frame-rate conversion, supporting formats up to 4096 × 2160 at 60p. Its flexible routing allows HDMI and SDI outputs to be sourced from either input or the internal scaling engine, making it suitable for connecting equipment operating at different resolutions and frame rates.
Four 12G-SDI outputs allow the unit to serve as a 1-to-4 distribution amplifier, while the built-in test pattern generator offers 58 patterns, including luma and chroma zone plates. An integrated LCD and buttons provide direct access to settings, with USB control and firmware updates also available. Housed in a robust aluminium enclosure, the fanless 12G-CROSS provides quiet operation for studio, broadcast and live production environments.
