About the Blackmagic Design CONVMCAUDS4K Mini Converter Audio to SDI 4K Signal Converter

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.

Key Features

  • 4 Analog or 8 AES/EBU Audio Channels Embedded
  • 6G‑SDI with Full 4K Support
  • Redundant SDI Input and Re-clocking
  • Flexible Configuration via DIP or USB

FAQs about Blackmagic Design CONVMCAUDS4K Mini Converter Audio to SDI 4K Signal Converter

What is the Blackmagic Mini Converter Audio to SDI 4K?

It is a broadcast-grade audio embedder that integrates external analog or digital AES/EBU audio signals into any SDI video feed. It supports multi-rate 6G-SDI, allowing you to embed audio into SD, HD, and Ultra HD video streams up to 2160p30.

What audio inputs are supported on the converter?

The unit features four 1/4-inch (6.35 mm) professional audio jacks that can be switched between balanced analog audio or digital AES/EBU audio. It can embed up to four channels of balanced analog audio or eight channels of digital AES/EBU audio simultaneously.

What video resolutions and frame rates does it support?

The 6G-SDI interface supports standard-definition (NTSC/PAL), high-definition (720p, 1080i, 1080p up to 60 fps), and Ultra HD formats up to 3840x2160 at 24, 25, and 30 fps. The converter automatically detects the incoming video format and switches internal processing instantly.

Can it replace or overwrite existing audio on an SDI feed?

Yes, the unit allows you to either overwrite existing embedded SDI audio channels or insert new channels into previously empty audio slots. This lets you replace a camera's scratch audio track with a clean master feed from an audio mixing console.

How do you configure settings on the converter?

Settings can be adjusted instantly using the built-in mini DIP switches located on the side panel, with a convenient printed diagram right on the chassis. Alternatively, you can configure detailed routing, channel mapping, and updates over USB using Blackmagic's Converters Setup utility software.

Does the converter require an external computer to operate?

No, it is a standalone hardware converter that functions completely independently without a computer connection once powered on. USB connectivity is only required for firmware updates or software-based configuration adjustments.

Does the converter pass through video without latency or alteration?

Yes, the SDI input signal is equalized, reclocked, and forwarded to the SDI output with pristine signal integrity. Reclocking eliminates digital jitter, allowing the video feed to travel over longer downstream cable distances.

What power supply does the converter use?

The unit runs on standard +12V DC power and includes a universal power supply with interchangeable international wall socket adapters. It features a threaded locking DC connector to prevent accidental power disconnections during live productions.
