The Blackmagic Design Mini Converter SDI to Audio is a compact and specialized interface device designed to extract embedded audio tracks from a professional SDI video signal and convert them into discrete analog audio outputs. This unit serves a critical function in broadcast, live event, and post-production environments where audio needs to be separated from the video feed for independent monitoring, routing, or recording.

It accepts a standard SDI input, supporting a wide range of signal formats from standard definition up to high definition, and then decodes up to 16 channels of embedded digital audio carried within the SDI stream. These channels are then made available via two stereo 3.5mm mini-jack outputs, each providing a pair of analog audio channels, allowing for flexible connection to headphones, small speakers, or other analog audio equipment.

The converter is housed in a durable, pocket-sized metal casing and is powered via an included USB cable, making it highly portable and easy to integrate into existing setups without requiring external power supplies. Its straightforward, plug-and-play operation requires no configuration, making it an essential tool for audio engineers, video editors, and technicians who need a reliable and immediate method to monitor or utilize the audio component of an SDI source.
