Overview

The Blackmagic Design Teranex Mini SDI to Audio 12G is a dedicated converter built to extract embedded audio from SDI video signals across the full spectrum of professional formats. Whether you are working with standard definition, HD, 2K, or Ultra HD 4K content, the unit automatically detects the incoming signal and outputs up to four channels of AES/EBU balanced digital audio through its XLR connectors. The 12G-SDI input means it can handle single-link UHD signals without requiring quad-link setups, streamlining cabling in modern production environments. A 12G-SDI loop output passes the video signal onward, making the converter easy to integrate into existing signal chains without the need for additional distribution amplifiers.

Designed in the Teranex Mini form factor, this converter occupies minimal space and can be used standalone on a desk or mounted in a rack using an optional shelf. Configuration and firmware updates are handled through USB or Ethernet, allowing operators to adjust settings such as assigning timecode output to the right XLR connector. This makes the unit particularly useful in broadcast, live event, and post-production scenarios where SDI audio needs to be broken out to external mixers, monitoring systems, or recording devices with professional digital audio inputs.

Pros & Cons

👍 Pros

  • Supports the full range of SDI formats from SD to Ultra HD 4K on a single 12G-SDI input
  • Includes an SDI loop output so the video signal can continue to other equipment in the chain
  • Compact Teranex Mini form factor fits easily into tight rack and equipment spaces
  • Automatic signal detection eliminates manual switching when input formats change
  • Right XLR output can be reconfigured for timecode, adding workflow flexibility

👎 Cons

  • Limited to 4 channels of AES/EBU audio output, which may not cover all embedded channels in a 16-channel SDI signal
  • Does not include analog audio outputs, restricting use with legacy analog equipment
  • Requires a separate Teranex Mini rack shelf or mounting solution for permanent installations
  • No front-panel display for monitoring audio levels or signal status without additional software

Frequently Asked Questions

It outputs 4 channels of professional 110-ohm balanced digital audio via AES/EBU XLR connectors. The right XLR connector can also be configured for timecode output.
No, the Teranex Mini automatically detects and switches between SD, HD, 2K, and 4K SDI input signals without any manual intervention.
