The Blackmagic Design CONVMCAUDS4K Mini Converter is a compact device that embeds analog audio signals into a 4K SDI video stream. It accepts up to four channels of analog audio via XLR inputs and combines them with an incoming 4K SDI video signal, outputting a single SDI signal with embedded audio. This is essential for workflows where audio from a mixer or microphone preamps needs to be synchronized and transported alongside video within a broadcast or production system, simplifying cabling and ensuring perfect lip sync.

The converter is designed for easy integration, featuring automatic signal detection and operation without the need for external configuration or software. It supports high-quality 24-bit audio sampling and can derive its power from the connected SDI input using the SDI Phantom Power feature or from an optional external power supply, making it highly flexible for both installed and mobile setups. Its small, rugged metal casing allows it to be easily mounted or placed inconspicuously in a signal chain.

This mini converter solves a common integration challenge in professional video production, providing a reliable and straightforward method to merge separate audio and video feeds. It is a vital tool for live production trucks, broadcast facilities, and content creators who need to embed high-quality audio into their 4K SDI video workflow efficiently and reliably.
