The Blackmagic Design OpenGear SDI to Audio Converter is a professional broadcast module designed to extract, or de-embed, high-quality digital audio channels from an SDI video signal and output them as discrete analog audio signals. Installed in a compatible openGear frame, this card serves a critical function in facilities where embedded audio from video sources—such as camera feeds, servers, or live production switchers—needs to be connected to analog sound systems, mixing consoles, intercoms, or monitoring equipment. The converter takes an SDI input, separates the embedded audio from the video, and performs a high-fidelity digital-to-analog conversion, outputting the audio on balanced analog connections like XLR or TRS. This process is essential for integrating digital video infrastructure with the extensive world of analog audio gear still prevalent in many broadcast and production environments.

The module is engineered for signal integrity and flexibility, typically supporting multiple audio channels (often up to 16) from a single SDI stream and providing them on several stereo or mono output pairs. It automatically detects the audio format embedded in the SDI signal and converts it with precise timing to maintain lip-sync accuracy. Advanced features may include level control, channel routing, and status monitoring for each audio output. As part of the openGear system, it leverages the frame's centralized power, cooling, and management, offering a more reliable and serviceable solution than a collection of standalone de-embedders, especially when processing numerous SDI feeds.

Remote monitoring and control of the card are typically available through the openGear frame's management software, allowing audio engineers to adjust levels and monitor signal presence from a central location. Its single-slot design enables high-density installation, making it possible to de-embed audio from many SDI sources in a compact rack space. This is invaluable in broadcast master control rooms, live production trucks, and post-production facilities where clean, isolated audio feeds are required for separate mixing, distribution, or archiving. By providing a dedicated, modular solution for audio extraction, this OpenGear converter ensures reliable and high-quality audio-video separation within professional workflows.
