Decimator Design 12G-CROSS HDMI/SDI 4K Cross Converter

The Decimator Design 12G-CROSS is a small, low power portable converter encased in a solid robust aluminium case and does not contain a noisy fan. Allowing it to be used in almost any environment. This unit allows either of the HDMI or SDI outputs to be simultaneously sourced from either the HDMI or SDI input or the new 4K scaling engine.

The 4K scaling engine can be driven by either the SDI or HDMI input, supports horizontal and/or vertical flipping and can be locked to either the SDI, HDMI or Genlock input. The 12G-CROSS now supports 294 VESA formats on the HDMI Input!

The 4K scaling engine can scale and/or frame rate convert between any of the following 57 formats:
– (3840 or 4096) x 2160p50/59.94/60 via HDMI or 12G-SDI
