Blackmagic Design Teranex Mini 12G-SDI to Quad SDI Converter

SKU CH-4YC3-FC3T4

Converts 12G-SDI signals into four HD-SDI outputs for video walls and broadcast workflows

  • Converts 12G-SDI to Quad Link SDI for Ultra HD connectivity
  • Splits Ultra HD SDI into four HD outputs for video wall displays
  • 12G-SDI loop-through maintains signal integrity across multiple devices
  • Supports Level A and Level B 3G-SDI equipment for broad compatibility
  • Durable compact design built for broadcast production and post-production environments

Professional 12G-SDI to Quad SDI conversion

The Blackmagic Design Teranex Mini converts 12G-SDI signals into Quad Link SDI for broadcast, production and post-production workflows. It bridges the latest Ultra HD equipment with existing Quad Link infrastructure. The compact unit is built for professional environments where reliable signal conversion is essential.

Handles 12G, 6G, 3G and SD-SDI formats

The converter accepts 12G HD-SDI, 6G HD-SDI, 3G HD-SDI and standard SDI inputs for 4K and UHD workflows. It separates Ultra HD SDI into four independent HD SDI outputs for video wall displays. The 12G-SDI loop-through preserves signal integrity across daisy-chained devices.

12G-SDI loop-through for signal distribution

A built-in 12G-SDI loop-through passes the incoming signal onward without degradation. This allows the converter to sit inline while feeding Quad SDI outputs to monitors or recorders. The feature is critical for installations that must maintain a clean signal path through multiple devices.

Questions about this item

Will the 12G-SDI loop-through let me keep my existing 6G HD-SDI monitor in the chain without signal loss?

The loop-through passes the 12G-SDI signal onward untouched, so downstream 6G HD-SDI gear receives the same clean feed.

How can I verify the converter is correctly splitting a 4K/UHD signal into four HD SDI outputs?

Check each of the four SDI outputs on a waveform monitor or HD display; all should show matching HD frames derived from the single Ultra HD source.

Does the box include the four BNC cables needed for the Quad SDI outputs, or must I buy them separately?

Only the converter and its power supply are included; four BNC cables for the Quad SDI outputs must be purchased separately.
