Product Information

Full details

The Blackmagic Design Mini Converter SDI to Audio is designed for audio engineers, broadcasters, and video professionals who need to extract audio from SDI video signals. Its key benefit is the flexible de-embedding of up to four channels of analog audio or eight channels of AES/EBU digital audio, directly from an SDI feed, enabling seamless integration with external audio equipment. A potential caveat for users is the reliance on 1/4 inch jack connectors for audio output, which may require specific cabling not always found in standard audio setups.

FAQs

Can this converter de-embed audio from HDMI?

This specific model, the Mini Converter SDI to Audio, de-embeds audio from SDI connections. Other Blackmagic Mini Converter models may support HDMI input and audio de-embedding from HDMI.

What type of audio cables do I need for the outputs?

The converter uses standard 1/4 inch jack connectors. For analog audio, you will need balanced 1/4 inch jack cables. For AES/EBU digital audio, you will also use 1/4 inch jack connectors, often referred to as TRS connectors, but ensure your AES/EBU equipment is compatible.

How do I switch between analog and digital audio?

There are mini switches on the side of the unit that allow you to select between balanced analog audio and AES/EBU digital audio output. Refer to the unit's markings or the manual for precise switch positions.

Does the converter support Dolby Digital or other multichannel formats?

The converter de-embeds up to 8 channels of AES/EBU digital audio or 4 channels of analog audio. Support for specific multichannel formats like Dolby Digital depends on the embedded audio within the SDI signal and the capabilities of your downstream audio equipment.

Can I use the SDI loop-through output to connect to multiple converters?

Yes, the SDI loop-through output allows you to send the original SDI signal to another device, such as a second Mini Converter, enabling you to de-embed additional audio channels or use the signal for monitoring.

What is the purpose of the redundant SDI input?

The redundant SDI input provides a backup connection. If the primary SDI input signal is lost for any reason (e.g., cable issue), the converter automatically switches to the redundant input to maintain an uninterrupted audio feed.

Does it come with a power supply?

Yes, the Mini Converter SDI to Audio includes a 12V universal power supply with international socket adapters for worldwide use.

Troubleshooting

No audio output

Ensure the SDI input signal carries audio. Verify that the correct audio output type (Analog or AES/EBU) is selected using the mini switches. Check that audio cables are securely connected to both the converter and the destination device. Confirm the destination device is powered on and configured to receive the correct audio format.

Video signal is lost or intermittent

Check the SDI cable connections for damage or loose fittings. Ensure the SDI source is active and outputting a valid signal. If using the redundant input, verify the backup SDI source is functioning correctly and attempt to trigger the failover manually or by disconnecting the primary source.

Incorrect audio format (e.g., digital instead of analog)

Confirm the mini switches on the side of the converter are set to the desired audio output format (Analog or AES/EBU). Ensure the connected audio equipment is compatible with the selected format.

Converter not recognized by computer for firmware updates

Ensure the USB cable is securely connected to both the converter and the computer. Try using a different USB port or cable. Make sure you have the latest drivers or Blackmagic Desktop Video software installed on your computer.

Pros and Cons

Pros

  • Flexible audio de-embedding for both analog and digital formats.
  • Automatic detection and switching between SD and HD video standards.
  • Robust design with redundant SDI input for critical applications.
  • Uses standard 1/4 inch jack connectors for common audio cable compatibility.
  • Compact and robust build quality suitable for professional environments.
  • Supports the latest 3 Gb/s SDI technology for future-proofing.

Cons

  • Requires specific 1/4 inch jack cables for audio connections, which may not be universally available.
  • The unit requires an external power supply.
  • Analog audio outputs are balanced, requiring appropriate connection to downstream equipment.
  • Only one model is needed for both analog and digital audio, but the user must manually switch the type.
  • Does not de-embed audio from HDMI sources (relevant for HDMI models only).

Setup, Compatibility & Care

Setup: Connect your SDI video source to the SDI input and your audio destination (mixer, recorder, monitors) to the analog or AES/EBU audio outputs using standard 1/4 inch jack cables. Connect the included 12V universal power supply to the unit and a power outlet. Use the mini switches on the side to select between analog or AES/EBU audio output. Connect a secondary SDI cable to the redundant input if needed. A loop-through SDI output can be used to feed another device.

Compatibility: Supports NTSC, PAL, 1080i/59.94, 1080i/50, 1080psf/23.98, 1080psf/24, 720p/59.94, and 720p/50 video formats. New formats can be added via USB firmware updates. Compatible with standard broadcast analog and AES/EBU audio equipment.

Care: Keep the unit clean and dry. Use a soft, dry cloth for cleaning. Avoid exposing it to extreme temperatures or humidity outside the specified operating range. Ensure the power cable is securely connected, utilizing the provided tie-point to prevent accidental disconnection.
