Mini Converter Audio to SDI 4K

Blackmagic Design Mini Converter Audio to SDI 4K embeds four channels of balanced analog audio or eight channels of AES/EBU digital audio into SD, HD, 3G or 6G-SDI video signals. It supports formats from 525i NTSC up to 4096 x 2160p30 4K. A universal 12 V power supply with international adapters is included.

Broadcast engineers embedding external audio

Suits broadcast engineers who need to embed analog or AES/EBU sources into an SDI stream for live production or post workflows. Not for buyers who require HDMI input or output, or who need to de-embed audio from an SDI signal.

6G-SDI reclocked output with redundant input

The single specification that decides fit is the 6G-SDI reclocked output with automatic redundant-input failover. It ensures clean 4K transport and signal continuity when the primary SDI feed is lost.

Highlights

  • Embed 4 analog or 8 digital audio channels into SDI video
  • Redundant SDI input switches automatically if main signal fails
  • Supports SD through 6G-SDI and 4K UHD formats automatically
  • 48 kHz 24-bit audio sampling meets broadcast standards
  • USB port enables configuration and firmware updates on Mac or Windows

Questions about this item

How do I connect analog audio to the 1/4 inch jacks and avoid the common mistake of unbalanced cables?

Plug four channels of professional balanced analog audio into the standard 1/4 inch jack connections; the mistake is using unbalanced cables which can introduce noise and ground loops in studio environments.

Will the USB port need firmware updates over time and how are they applied?

The USB port is used for software upgrades and configuration via the included updater application on Mac OS X 10.9 or later and Windows 7 or 8; connect to a computer to apply updates when released.

At what point does the 8.40 Watt power draw become a thermal limit during continuous 4K operation?

The converter consumes 8.40 Watts and operates from 12V to 31V DC with the supplied universal power supply; sustained 4K embedding runs within this envelope without a stated thermal throttle point.
