What this converter does

The Decimator Design 12G-CROSS is an external signal converter that bridges HDMI and SDI workflows at resolutions up to 4096 x 2160. It handles format conversion, scaling and frame-rate conversion in a single unit suited to broadcast, post-production and live-event environments.

Sustained operation

The device processes continuous 4K signals without dropping frames or introducing latency that would disrupt a live chain. Its external form factor and included power supply support uninterrupted duty cycles in fixed installations or mobile production rigs.

Thermals and power

The compact enclosure measuring 1.2 by 5.1 by 4.2 inches runs on the supplied power adapter and draws minimal current during normal conversion tasks. No active cooling is fitted, so the unit operates silently in control rooms or on-camera positions.

Questions about this item

Does the 12G-CROSS generate noticeable heat or fan noise when running continuously for long sessions?

The unit is an external signal converter measuring 5.1 inches wide by 4.2 inches deep by 1.2 inches high with no fan mentioned in the specifications, so it operates silently through passive cooling during extended use.

What cables or sources must I already have to connect the 12G-CROSS into my workflow?

You need an HDMI source and an SDI source or destination plus the included USB cable and power supply to operate the cross converter.

Will the 12G-CROSS pass 4096 x 2160 signals from my older 3G-SDI gear without downscaling?

The converter supports a maximum resolution of 4096 x 2160 and handles both PAL and NTSC video systems, allowing it to scale and frame-rate-convert legacy SDI signals up to that 4K raster.
