Blackmagic Design Teranex Mini HDMI to SDI 12G Converter Overview

Professional-Grade Conversion with Advanced Connectivity

The Foto Crown Provides Blackmagic Design Teranex Mini HDMI to SDI 12G Converter delivers a high-performance signal conversion solution for broadcast, post-production, and live event environments. Designed to support HDMI input signals up to 4K DCI (4096x2160p) and output them through dual 12G-SDI connections, this compact yet powerful unit meets the demands of today’s professional video workflows.

With 12G-SDI capabilities, this converter enables the transmission of high-resolution video signals over a single cable. This dramatically simplifies infrastructure needs for facilities transitioning to Ultra HD and 4K. The ability to send 4K DCI signals up to 70 feet using 6G-SDI cabling, and eventually over 250 feet with 12G-SDI, makes it ideal for futureproof setups.

HDMI to SDI Conversion with Broadcast Accuracy

Blackmagic’s renowned Teranex video processing powers the conversion engine, ensuring pristine signal integrity during every conversion. Whether the signal is HD, 3G, 6G, or 12G, the unit adapts dynamically to deliver robust performance under demanding production conditions.

Optimized Audio Integration via Full-Size XLR Inputs

In addition to HDMI video, the Teranex Mini supports the integration of professional audio sources through dual XLR connectors. These full-size connections are switchable between balanced analog and AES/EBU digital audio, offering greater flexibility for integrating with a variety of sound systems and audio workflows. This feature is particularly useful in professional environments where embedded audio is not sufficient or external sources must be combined.

Smart Thermal Management for Rack Installations

Thermal efficiency is a key focus of the Teranex Mini design. Built-in heat pipes and an automated fan system help regulate internal temperatures without introducing excessive noise. When units are rack-mounted side by side, the design allows each unit to assist in cooling adjacent units, effectively maintaining system integrity and minimizing thermal stress across the array.

If the unit begins to overheat, it automatically sends alerts via the Ethernet utility and on the front panel, ensuring users are notified immediately. This level of thermal awareness and redundancy is critical for long-term stability in multi-unit installations.

Versatile Installation and Power Options

With its compact form factor, the Teranex Mini is ideal for installations where space is limited—such as broadcast trucks, flypacks, or concealed cable ducts. For more traditional setups, up to three units can be mounted in a single 1U rack shelf, making them perfect for dense system builds.

Power flexibility is another major advantage. Additionally, the Ethernet port supports Power over Ethernet (PoE), eliminating the need for separate power sources in networked environments.

Flexible Control via Ethernet or Optional Smart Panel

The rear Ethernet port serves dual purposes: remote control and PoE input. Users can manage the converter from any Mac or Windows PC using the included Converter Utility software, enabling centralized control across a large number of units in studio environments.

By default, the Teranex Mini includes a basic front panel with dip switches for fast configuration. Each switch corresponds to a printed settings diagram, offering immediate access to core functions without needing software. However, users can upgrade to the optional Smart Panel, which introduces a high-resolution color LCD, control knob, and navigation buttons.

With the Smart Panel installed, users gain on-device video previews, real-time audio level monitoring, timecode display, and a menu-driven interface. This dramatically enhances the usability and oversight of the converter during live workflows or critical switching operations.

Industrial Build Quality with Professional Workflow Integration

It fits naturally into professional AV, broadcast, and film production pipelines, providing the bridge between HDMI sources and high-performance SDI infrastructure. The unit supports all major SDI standards including HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI, and automatically detects and adapts to the incoming format. Its robust design, advanced connectivity, and flexible integration features make it a smart investment for professionals needing a long-term HDMI to SDI solution.

Seamless Conversion, Monitoring, and Control in One Compact Unit

Whether for permanent installation in a control room or as part of a mobile production rig, the Teranex Mini HDMI to SDI 12G Converter delivers seamless, accurate conversion for demanding video environments. Its integration of signal conversion, thermal intelligence, network control, and audio flexibility into a single chassis speaks directly to modern production needs—where quality, efficiency, and expandability matter most.
