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

Professional 4K HDMI to SDI Converter With Real-Time Frame Rate & Scaling Control

The DECIMATOR 12G-CROSS is a standalone HDMI/SDI cross converter designed for professional video workflows needing robust format flexibility. It enables users to convert video between HDMI and SDI (including 12G/3G/HD/SD-SDI) while incorporating both scaling and frame rate conversion. Whether you're integrating mixed signal formats or preparing feeds for broadcast, live production, or streaming, this compact yet powerful converter eliminates the need for a PC to make changes. It’s built for on-the-go productions where time-saving, reliability, and format control are essential.

Massive Format Flexibility With 3249 Conversion Combinations

The built-in frame rate and scaling engine lets you convert nearly any signal configuration to your desired output. With support for over 294 VESA formats through HDMI and 57 selectable conversion presets, you can adapt HDMI or SDI inputs into virtually any output format needed. The 12G-CROSS supports UHD 4K (3840x2160 and 4096x2160) up to 60p over both HDMI 2.0 and 12G-SDI, alongside full compatibility with standard HD formats like 1080p, 1080i, and 720p. Its versatility ensures you’ll never be stuck without the right output configuration again.

Standalone Design With Built-In LCD and Button Control

Unlike traditional converters that rely on software or DIP switches, the 12G-CROSS gives you full control directly from the unit. An onboard LCD screen and four-button interface make it easy to navigate settings, change output formats, assign SDI outputs, and rearrange audio channels—all without a computer. This makes it ideal for remote setups, field shoots, and installations where fast format switching is required without any software dependency.

Advanced Output Options Including Distribution Amp Capabilities

The 12G-CROSS isn’t just a converter—it can also function as a 1-to-4 SDI distribution amplifier. With two SDI output pairs and one HDMI 2.0 output, the unit can simultaneously deliver multiple synchronized outputs. SDI output pair one can either mirror the SDI input or output the same signal as pair two, offering excellent flexibility for routing signals in multi-monitor, recording, or broadcast environments.

Professional Signal Sync With Genlock and Audio Flexibility

For broadcast-grade synchronization, the device includes a 12G-SDI genlock input that allows for proper signal timing when integrated into larger systems. Audio output routing is fully customizable—SDI and HDMI audio pairs can be rearranged to suit your signal chain requirements, whether you’re feeding embedded audio to switchers, monitors, or encoders.

Reliable Power Connection With Threaded Locking Input

To minimize accidental disconnections during operation, the unit features a threaded locking power connector. This simple but essential design choice ensures that your video workflow remains uninterrupted—particularly useful during live events or mobile productions where reliability is critical. The included power supply and USB cable also support firmware updates and external control when needed.

Compact Yet Fully Featured For Broadcast, AV, and Live Production

Despite its size, the DECIMATOR 12G-CROSS delivers a full suite of high-end features typically found in rack-mounted systems. It’s ideal for video engineers, AV integrators, streamers, and broadcast professionals who need a trusted signal converter with 4K UHD support, wide input compatibility, and standalone control. The rugged metal housing and intuitive interface round out its readiness for any production challenge.
