The DD-CROSS-12G is a versatile and powerful HDMI/SDI 4K cross converter designed to meet the demands of modern video production environments. Encased in a robust aluminum case, this compact (4.2" x 5.1" x 1.2") and low-power device operates silently without a noisy fan, making it suitable for any setting. The DD-CROSS-12G features a 4K scaling engine capable of handling both SDI and HDMI inputs, supporting horizontal and vertical flipping, and locking to SDI, HDMI, or Genlock inputs. It can scale and convert frame rates between 351 input formats and 57 output formats, including 294 VESA formats via HDMI input, 4K resolutions up to 60p via HDMI or 12G-SDI, and various HD and SD formats. The device includes four (12G/6G/3G/HD/SD)-SDI outputs, allowing it to function as a 1 to 4 distribution amplifier. The audio pairs in the SDI and HDMI outputs can be rearranged as needed. The DD-CROSS-12G is equipped with an easy-to-use LCD screen and button control system, eliminating the need for complicated LED/button controls or dip switches. It also includes a USB port for control and firmware updates, a metal thread locking DC power socket, and comes with a power supply and USB cable.
